Polyurethane Molding Fireplaces: Portals for Electric and False Fireplaces

Fire in the home is the most ancient symbol of coziness, protection, and the family hearth. But modern apartments lack chimneys, reinforced concrete floors cannot bear the weight of stone fireplaces, and building codes prohibit open flames in multi-story buildings. The dream of a fireplace remains a dream — until a solution appears:polyurethane stucco fireplacecreates the visual reality of a classic hearth without a chimney, foundation, or fire inspection permits. An electric fireplace with 3D flame simulation inside a polyurethane portal provides dancing firelight, glowing embers, and even warmth (built-in heater) — the full atmosphere of a real fireplace with zero installation complexity. A faux fireplace without a firebox, with decorative candles, garlands, and a mirrored back panel — pure aesthetics, a compositional centerpiece for the living room, a place where the gaze rests and finds peace.

Polyurethane stucco fireplacesare installed over a weekend. The portal weighs fifteen to thirty kilograms — two people can lift it, attach it to the wall with polyurethane glue and anchors for reliability. The electric fireplace is inserted into the firebox opening and plugged into an outlet — the fireplace works. No construction permits, layout alterations, or wet work required. The cost of a portal plus electric fireplace kit is fifty to one hundred fifty thousand rubles (depending on size, decorative complexity, and firebox quality) versus one to one and a half million for a real marble fireplace with a chimney. This affordability turns a fireplace from a privilege of a country house into a reality for a city apartment.

Styles: from antiquity to modern

Classicism. Symmetry, proportions, restraint. Side posts — pilasters with Corinthian or Ionic capitals (scrolls, acanthus leaves with moderate detail). Shelf straight, without curves, with a profiled cornice (dentils — small teeth, or simple moldings). Firebox facade framed with molding featuring ornamentation (meander, palmettes, laurel wreaths). Color traditionally white or ivory; sometimes the shelf is painted to resemble wood (wenge, dark oak) — contrasting with white posts.For a fireplace, polyurethane stuccoin a classical style — the choice for conservative interiors where timeless elegance is valued without fashionable excess.

Baroque. Opulence, dynamism, excess. Side posts — twisted or richly relief semi-columns (garlands of flowers, cherubs, cartouches). Capitals large, multi-tiered, with deep shadows. Shelf curved, with a wavy front edge, supported by carved brackets (S-shaped scrolls with leaves). Firebox facade adorned with appliqués (symmetrical cartouches, shells, wreaths). Coloring often polychrome — white base plus gilding of protruding details (capitals, brackets, central appliqués). Effect of luxury, palace-like grandeur.

Empire. Monumentality, military severity, imperial pathos. Side posts — square pilasters with minimal relief or smooth, capitals simplified (Doric — square slab on a cylinder). Shelf massive, straight, with a sharp projection (cornice without ornament or with simple bands). Firebox decoration — appliqués in the form of military attributes (shields, swords, laurel wreaths, eagles), symmetrical, graphically precise. Color dark (black, dark green, burgundy) with gilding of bronze details — dramatic, solemn.

Art Nouveau. Flowing lines, asymmetry, botanical motifs. Side posts curved, without capitals (lines flow into the shelf seamlessly). Ornament — stylized flowers (irises, lilies, poppies), winding stems, female profiles with long hair. Shelf can be asymmetrical (one edge longer), curved like a wave. Color muted (grey-green, dusty pink, lilac) or natural wood tones (walnut, ash). Art Nouveau is rare in ready-made portals (requires custom design), but some manufacturers offer simplified versions.

Modern classic. Simplification of traditional forms, minimization of ornament, preservation of proportions. Pilasters smooth or with one or two vertical grooves (fluting), capitals minimalist (simple roll). Shelf without decoration, a rectangular block with clear edges. Firebox facade smooth or with one profiled molding. Color white, grey, beige — a neutral background that doesn't overload the interior. Suitable for contemporary, Scandinavian style, minimalism with classical notes.

Kit contents: what's included, what to buy separately

Basic ready-made portal kit:

• Two side posts (left and right), height from floor to the lower edge of the shelf.

• Mantel shelf (one piece or two to three parts if the width is large).

• Decorative elements for the firebox facade (moldings, appliqués, hearth surround).

• Mounting kit (sometimes): glue, screws, instructions.

What is NOT included:

• Electric fireplace (firebox). Purchased separately, chosen to fit the portal's firebox opening size.

• Paint (if you want a color different from the basic primer).

• Additional decoration (if you want to enhance the portal — add corbels under the shelf, appliqués on the posts, a frieze above the firebox).

Some manufacturers offer complete portal+electric fireplace solutions — convenient (compatibility guaranteed, visualization of the finished composition available), but the choice of fireboxes is limited to the seller's offerings.

Assembling a portal from separate elements: a construction set for adults

An alternative to a ready-made portal is self-assembly from individual molding elements.Polyurethane fireplace molding, created according to an individual project, is unique — the dimensions precisely fit your space, the style is exactly the one you like, the richness of decor is adjustable.

Selection of elements: basic set

Side posts. Pilasters or half-columns. Height is determined by the desired portal height minus the shelf height minus the plinth height (if used). Typical post height is one hundred to one hundred twenty centimeters. Pilaster width is eight to twenty centimeters, chosen to match the portal scale (narrow portal — narrow pilasters, wide — massive ones). The capital style (Doric, Ionic, Corinthian) determines the style of the entire portal.

Fireplace mantel. Horizontal board or beam. Length equals the portal width (distance between the outer edges of the posts plus twenty to forty centimeters of overhang at the edges). Shelf width (depth) is fifteen to thirty centimeters (the wider, the more space for decor — vases, candlesticks, frames). The shelf can be made of polyurethane (lightweight, decorated with a carved profile on the front edge) or wood (solid oak, ash — heavier, more noble, more expensive). Polyurethane shelves often imitate wood texture (painted to look like wood, texture applied during casting).

Plinth. An optional element, but adds completeness. It is a profiled beam (an enlarged height baseboard) installed at the base of the posts. Plinth height is ten to twenty centimeters, width corresponds to the post width. The plinth visually raises the portal above the floor, creates a base, an architectural foundation.

Moldings and overlays. Decorative elements for framing the firebox opening, decorating posts, the frieze between posts and shelf. Moldings are narrow strips with relief (width three to eight centimeters), glued around the perimeter of the firebox, creating a frame. Overlays are carved elements (cartouches, rosettes, wreaths), glued onto posts, above the firebox, under the shelf — accentuating the composition.

Design: dimensions and proportions

Before purchasing elements, draw a scale sketch. Determine:

• Portal width (depends on wall width, electric fireplace size, room proportions). Typically one hundred to one hundred fifty centimeters.

• Portal height (from floor to top of shelf). Typically one hundred to one hundred forty centimeters.

• Firebox opening size (for a specific electric fireplace plus two to three centimeters on the edges for easy installation).

• Distance from floor to bottom of firebox (usually twenty to thirty centimeters — the hearth at a height convenient for viewing while seated).

Calculate element dimensions:

Post height = Portal height - Shelf height - Plinth height (if used) - Capital height.

Example: portal height 130 cm, shelf 8 cm high, plinth 15 cm, capital 12 cm. Pilaster shaft height = 130 - 8 - 15 - 12 = 95 cm.

Firebox opening width = Electric fireplace width + 4-6 cm (gaps).

If the electric fireplace is 60 cm wide, the firebox is designed to be 64-66 cm wide.

Installation: sequence of operations

Step 1: Marking. On the wall, mark the vertical axes of the posts (distance between axes equals internal portal width plus post width), the horizontal line of the plinth bottom edge (at floor level or higher if the plinth is set back from the floor), the horizontal line of the shelf top edge.

Step 2: Installing plinths. Plinths are glued to the wall with polyurethane adhesive, aligned with markings, pressed. For heavy portals, plinths are additionally secured with anchors (two to three anchors per plinth, drilled through polyurethane into the wall, screwed in, heads countersunk, filled).

Step 3: Installing posts. Pilaster shafts are installed on plinths (if present) or directly on the floor. Glued to the wall with adhesive, aligned vertically with a level. If posts are tall (over a meter), secured with anchors at three to four points along the height.

Step 4: Installing capitals. Capitals are placed on top ends of shafts, glued. If the capital is wider than the shaft (architecturally correct), it overhangs, rests on the shaft end, fixed with adhesive and screws from below (screwed through shaft into capital, invisible).

Step 5: Framing the firebox. Moldings are cut to firebox opening size, corners cut at forty-five degrees (miter box), glued around the perimeter. Creates a decorative frame, inside which the electric fireplace is installed.

Step 6: Installing the shelf. The shelf is placed on capitals, aligned (overhangs at edges equal), glued. Heavy wooden shelf additionally secured with screws or anchors (screwed from below through capitals into shelf, or from above through shelf into wall behind shelf — depends on construction).

Step 7: Installing decorative overlays. Overlays, corbels, friezes are glued to desired locations (above firebox, under shelf, on posts). Final decor, detailing the portal.

Step 8: Sealing joints. Joints between elements are filled with acrylic sealant (white, elastic), smoothed with a wet finger or spatula. After four to six hours, joints are sanded with fine sandpaper (grit 180-240), dust removed.

Step 9: Painting. The portal is primed (if base primer damaged during installation), painted with acrylic paint in two coats. Intercoat drying two to four hours. For effects (patination, gilding), additional layers are added.

Installation time: one to two days (excluding paint drying time).

Electric Fireplace Installation: Integrating Technology and Aesthetics

An electric fireplace is a technical element that creates an imitation of fire. Modern hearths use LEDs, mirrors, steam, and video projection to create realistic flames — dancing tongues, flickering embers, smoke (water vapor). Additionally, built-in thermal fans (power of one to two kilowatts) heat a room of fifteen to twenty-five square meters.

Types of Electric Fireplaces for a Portal

Built-in hearths. Compact units inserted into the firebox opening of the portal. The front panel of the hearth (where the flame is) is flat, flush with the portal facade or slightly recessed. The sides and back are technical (ventilation grilles, wires) — hidden inside the portal. The hearth depth is twenty to thirty centimeters — the portal must have corresponding depth or adjoin a wall niche (if the portal depth is insufficient, a frame made of profiles is built behind the portal, covered with drywall — a technical niche for placing the hearth).

Cassette hearths. Wide panoramic fireboxes, width up to one hundred twenty centimeters, height forty to fifty. They imitate a long-burning hearth with a row of logs or embers. Visually impressive (wide fire panorama), suitable for modern minimalist portals. They are built into the wall flush, the portal frames them around the perimeter.

Freestanding hearths. Decorative blocks in the form of a wood basket, a metal grate with coals. Placed inside a false fireplace, do not require rigid integration. Mobile (can be removed, moved), cheaper than built-in ones (fifteen to thirty thousand versus forty to one hundred twenty).

Connection and Placement

The electric fireplace is connected to a standard 220V outlet. The power consumption of hearths ranges from one hundred watts (only lighting, without heating) to two kilowatts (maximum heating). The wiring must withstand the load — wire cross-section two and a half square millimeters copper (for power up to three kilowatts) — standard apartment wiring.

The outlet is placed hidden — behind the portal, inside the technical niche. The wire from the hearth is connected to the outlet, the wire is hidden behind the portal elements. No visible wires — aesthetics are preserved.

Ventilation is critical. Hearth with thermal fans emit hot air (temperature sixty to eighty degrees at the outlet). Ventilation grilles (usually above the front panel or below) must remain open — closing leads to overheating, protection shutdown, breakdown.Portal for a fireplace made of polyurethaneis designed taking ventilation into account — a gap is left above the hearth (five to ten centimeters between the top of the hearth and the shelf), through which hot air exits freely.

False Fireplaces: Illusion Without Electricity

A real hearth is not always needed. Sometimes a visual composition is enough —polyurethane molding for a fireplacecreates a portal, inside which there is a decorative niche without technical components.

False fireplace construction

A frame made of wooden beams (cross-section three by four or five by five centimeters) or metal profiles (as for drywall) is attached to the wall. The frame repeats the shape of the portal — two vertical posts, horizontal crossbars above and below the firebox opening. Polyurethane molding elements — the portal facade — are glued or screwed onto the frame.

The firebox opening remains empty or is closed with a back wall (plywood, drywall, mirror). The back wall is painted (black paint — imitation of firebox depth) or covered with photo wallpaper (brickwork, stone). A mirrored back wall creates a depth effect — the firebox appears deeper, candles or lighting inside are reflected, doubled.

Filling the firebox: decor instead of fire

Without an electric fireplace, the firebox is filled with decorative elements:

Candles. A classic solution. Ten to twenty candles of different heights (from ten to thirty centimeters) are placed on the bottom of the firebox. Lit candles provide live fire, flickering, warmth (moderate, safe). Romantic, atmospheric, functional (candles can be lit according to mood, extinguished, changed). Disadvantage — candles burn down (need regular replacement), leave wax (need to clean the firebox).

LED lighting. LED strip is glued to the bottom or back wall of the firebox, plugged into an outlet or battery-powered. The light is directed upward — illuminates the firebox from inside, creates a soft glow. Color — warm yellow (imitation of fire) or multicolored (RGB strip, color control by remote). Additionally, decorative logs (made of polyurethane, painted to look like wood), stones, glass balls are placed inside the firebox — the lighting creates shadows, reflections, volume.

Decorative elements. A composition of branches (natural dry or artificial), pine cones, garlands (Christmas, year-round with warm light), mirror or glass accessories. Changed by season, mood, holiday. Summer — branches with green leaves, winter — spruce branches and pine cones, spring — flowering branches.

Books and baskets. If the fireplace is not planned to be used for fire imitation, the firebox turns into a storage niche. A stack of books, a wicker basket with a blanket, decorative boxes — functional use of space. Visually looks like a filled shelf, not like a fireplace — but the architectural frame of the portal preserves the compositional center.

Corner false fireplace: saving space

A standard portal is installed against a wall, takes up twenty to thirty centimeters of depth. In small rooms, this is critical. A corner false fireplace solves the problem — occupies a dead corner, does not steal space along the walls.

Corner portal construction: the frame is triangular in plan (two legs along the walls, hypotenuse — the portal facade). Decorative elements are installed on the facade — pilasters on the sides (running from the corner to the center of the facade), a shelf on top (triangular or trapezoidal in plan), the firebox opening in the center. Inside — decor or an electric fireplace (corner models exist, front panel at a forty-five-degree angle to the walls).

CornerPolyurethane fireplace moldingsaves space, creates a non-standard layout, highlights the corner as a compositional element. Suitable for studio apartments, small living rooms, bedrooms.

Fireplace Area Decoration: Molding Beyond the Portal

A fireplace is more than just a portal. The wall behind the fireplace, the space above the mantel, and the adjacent wall sections are decorated with molding, creating a cohesive fireplace zone.

Panel Above the Fireplace: Molding Frame

A molding frame (a rectangle made of moldings five to eight centimeters wide) is created on the wall above the fireplace mantel, sized one meter by one meter twenty or one meter twenty by one meter fifty. Inside the frame, a mirror is placed (visually expands the space, reflects the room and light), a painting (classical landscape, portrait, still life — stylistically coordinated with the interior), or a panel (molded, carved, fabric) is positioned.

The frame visually continues the verticality of the portal — the gaze moves from the floor (plinth) through the pilasters, the mantel, and the frame upward — the wall space is organized and structured. Without the frame, the wall above the fireplace remains empty, and the composition feels incomplete.

Pilasters on the Sides of the Fireplace: Wall Framing

The portal is installed in the center of the wall. On either side of the portal (at a distance of thirty to fifty centimeters from the outer edges of the portal pilasters), two additional pilasters are installed, extending from the floor to the ceiling (or to the ceiling cornice). The pilasters frame the fireplace area, highlight a section of the wall, and create an architectural accent.

Vertical panels (thirty to fifty centimeters wide) are formed between the pilasters and the portal — on these, sconces (wall lights), shelves with decor (vases, figurines), or molding frames for small paintings or photographs are placed. Symmetry (identical decoration of the left and right panels) enhances the classical nature of the composition.

Corbels Under the Mantel: Reinforcing the Support

The fireplace mantel visually rests on the capitals of the pilasters. However, corbels can be added — decorative brackets installed under the mantel between the pilasters. A corbel is a carved element twenty to forty centimeters high, ten to twenty wide, with an S-shaped or volute form. Corbels are installed in pairs (two symmetrically on either side of the firebox) or in trios (on the sides plus one in the center above the firebox).

Corbels do not bear a structural load (the mantel is held by the capitals and adhesive), but they visually enhance the perception of support, add three-dimensionality (the corbel protrudes from the wall, creating a play of light and shadow), and enrich the decor.

Painting and Patination: Final Finishing of the Portal

The base polyurethane is supplied primed white. A white portal is classic, universal, and suits most interiors. However, painting in other colors and applying decorative techniques create uniqueness.

Monochromatic Painting: Color Instead of White

Acrylic interior paint (matte or semi-matte) is applied to the portal in two coats. Intercoat drying time is two to four hours. Colors:

Ivory, cream. Warmer than white, softer, creates a sense of antiquity without stark whiteness. Suitable for classic interiors with a warm color palette (beige walls, honey-toned wood, golden textiles).

Gray. From light gray to graphite. Modern classic, Scandinavian style, loft with classic elements. A gray portal does not compete with bright interior accents (colored furniture, paintings), serving as a neutral background.

Black. Dramatic, contrasting, graphic. A black portal on a white wall is a sharp accent, attracts attention, dominates. Suitable for modern interiors, Art Deco, Gothic stylizations. Requires high ceilings and a spacious room (in a small space, a black portal feels oppressive).

Dark green, dark blue, burgundy. Rich, deep colors for formal interiors. The portal becomes a color accent, setting the tone for the fireplace zone. Combines with gilded elements (capitals, brackets are gilded separately).

Patina: effect of noble antiquity

Patina — an imitation of the patina of time, darkening of recessed relief, signs of oxidation, aging. Created through multi-layer painting:

Base coat. The portal is painted with a light-colored paint (white, ivory, light gray) in two coats and allowed to dry completely.

Patina layer. Dark paint (brown, gray, black, green, bronze) is diluted with water to semi-transparency and applied with a brush to the relief of the portal — into the recesses of the ornament, grooves, and joints of elements. The paint fills the recesses, remaining there as dark lines, shadows.

Blending. After one to two minutes (while the patina layer is not yet completely dry), excess dark paint is removed with a damp sponge or cloth. The protruding parts of the relief are wiped — they remain light (base color). The recesses remain dark (patina). Contrast, volume, and a depth effect are created.

Sealing. After the patina dries (four to six hours), the portal is coated with a matte varnish (acrylic or polyurethane) — protects the paint, fixes the patina, and gives a slight silky sheen.

Patination transforms a new portal into an antique one — creating the feeling that the fireplace is a hundred years old, has witnessed generations, and absorbed stories. Visually richer, deeper, and more aristocratic than flat monochromatic painting.

Gilding: Accentuating Details

Full gilding of the portal (covering the entire surface with gold paint) looks kitschy, overloaded, cheap (resembling plastic costume jewelry). Selective gilding of details is elegant, emphasizes the architecture, and adds luxury in a measured way.

Gilded:

• Capitals (fully or only the protruding elements — volutes, leaves of the acanthus ornament).

• Corbel brackets under the mantel (fully).

• Central overlays above the firebox (cartouches, wreaths, rosettes).

• Firebox framing moldings (only the protruding profile, not the entire strip).

Gilding is done with acrylic gold paint (color from light lemon to dark antique gold with a reddish tint) or wax paste with metallic pigment (applied with a finger or sponge, rubbed into the relief, creates a matte metallic sheen).

The portal is painted with a base color (white, ivory), dries. Gold paint is applied with a thin brush only to selected details. Effect: a light portal with gold accents — classic luxury without overload.

Safety: polyurethane and heat

Polyurethane is a polymer, a combustible material. When heated above one hundred twenty degrees it softens, above two hundred fifty it begins to decompose, releasing smoke. Ignition temperature is three to four hundred degrees (depends on density, composition). Safety requirements for usefireplace molding made of polyurethaneare strict.

Electric fireplaces: safe heat

Modern electric fireplaces do not heat the body above sixty to seventy degrees. The front panel (glass or plastic) is warm to the touch but not burning. Hot air exits through the top ventilation grilles — temperature at the outlet is seventy to eighty degrees, at a distance of ten centimeters it drops to forty to fifty. A polyurethane shelf located fifteen to twenty centimeters above the hearth heats up to thirty to forty degrees — absolutely safe, the material does not soften or deform.

Recommended clearances:

• From the top of the hearth to the lower edge of the shelf — minimum ten centimeters (optimally fifteen to twenty).

• From the side edges of the hearth to the inner surfaces of the portal posts — minimum five centimeters.

• From the back wall of the hearth to the wall — minimum three centimeters (ventilation).

Observing the clearances guarantees that polyurethane elements do not heat above fifty degrees — a safe temperature at which the material retains its properties for decades.

Bioethanol fireplaces: open flame

Bioethanol fireplaces burn bioethanol — alcohol, burning with a clean flame without smoke, soot, or sparks. Flame temperature is six hundred to eight hundred degrees. Open flame at a distance of thirty to fifty centimeters from polyurethane is dangerous — the material heats up, softens, and can ignite.

Safe installation of a bioethanol fireplace in a polyurethane portal requires:

• Enlarging the firebox opening (the bioethanol fireplace is installed deep inside, at a minimum distance of fifty centimeters from the front plane of the portal).

• Heat insulation of the firebox back wall (fire-resistant drywall, ceramic tile, metal sheet) — protects the wall and the back side of the portal from heating.

• Increasing the distance from the flame to the shelf (minimum sixty centimeters vertically) — shelf heating does not exceed fifty degrees.

Alternative — using the bioethanol fireplace outside the portal, the portal is purely decorative (false fireplace), the bioethanol fireplace is freestanding in front of the portal (at a distance). Visually, the fire is in the fireplace, but physically they do not contact — safe.

Candles: controlled flame

Candles inside a false fireplace are safe if rules are followed:

• Candles are placed on a non-combustible base (metal tray, ceramic tile, glass plate) — wax drips, fallen wick do not contact the firebox bottom.

• Distance from the candle flame to the top of the firebox opening minimum twenty centimeters (candle flame height five to ten centimeters, air heating above the candle — another ten centimeters, total fifteen to twenty to portal structures).

• Candles are not left unattended — they burn only when someone is in the room, extinguished when leaving.

Candles provide live flame, romantic atmosphere, but require responsibility.Portal for a fireplace made of polyurethanewith candles is safe with reasonable use.

Frequently asked questions

Is it possible to install a polyurethane portal around a real wood-burning fireplace?

Absolutely not. A wood-burning fireplace heats the wall around the firebox to one hundred to one hundred fifty degrees, the chimney to two hundred to three hundred. Polyurethane softens, deforms, and ignites at such temperatures. Only non-combustible materials are used for real fireplaces — stone, brick, plaster, wood with fire-retardant impregnation (and even that with limitations). Polyurethane portals are only for electric fireplaces, bio-ethanol fireplaces with proper clearances, and false fireplaces without real fire.

How much does a polyurethane portal weigh and will the wall support it?

A typical portal one hundred twenty centimeters high, one hundred ten wide, made of polyurethane with a density of 200 kg/m³ weighs twenty to thirty kilograms (depends on element thickness, richness of decor). Any load-bearing wall (brick, concrete, blocks) supports it without problems — polyurethane adhesive provides adhesion of two to three kilograms per square centimeter, the contact area of the portal with the wall is two to three thousand square centimeters — a tenfold safety margin. Additional fastening with anchors (two to four anchors) guarantees reliability. A drywall wall requires reinforcement — wooden backing or metal profiles are installed behind the drywall, to which the portal is attached.

Does the floor under the portal need reinforcement?

No. The weight of the portal, twenty to thirty kilograms, is distributed over the base area (portal width multiplied by depth — approximately 0.3-0.5 square meters). Pressure on the floor is fifty to one hundred kilograms per square meter — negligible (a standing person creates eight hundred to one thousand kg/m²). Any floor covering (laminate, parquet, tile, linoleum) supports the portal without deformation.

Can the portal be repainted after a few years if you want a different color?

Yes, easily. The surface is lightly matted (sanded with fine sandpaper to remove the gloss of the old paint, improve adhesion), dusted, primed (if the new paint color differs significantly from the old one), and painted with new paint in two coats. Polyurethane withstands multiple repaintings — the base is stable, does not age, paint adheres as to a new surface. Changing the portal's color is a way to update the interior without replacing the decor.

Can you make a portal from molding yourself without experience?

Yes, if you follow the instructions carefully. Installing polyurethane molding does not require special skills — basic tools are needed (tape measure, level, miter box for cutting corners, spatula, brushes), accuracy, patience. The adhesive forgives mistakes (you can remove an element, re-glue it), polyurethane is lightweight (one person can lift it), does not break if dropped. The first portal will take two to three days (accounting for adhesive and paint drying time), the next one — a day. The result is visually indistinguishable from professional installation, saving fifteen to thirty thousand rubles on crew work.

How much does a portal + electric fireplace kit cost?

A ready-made polyurethane portal of medium size (width one hundred ten, height one hundred twenty) in a simple classic style — twenty to thirty-five thousand rubles. A portal with complex decor (Baroque, Empire, rich ornamentation) — forty to seventy thousand. A large ceremonial portal — eighty to one hundred twenty thousand.

Built-in electric fireplace: budget (width fifty cm, simple flame imitation, heating) — fifteen to twenty-five thousand. Mid-range (width sixty, good flame imitation, brightness and heat adjustment) — thirty to fifty thousand. Premium (width seventy and more, realistic 3D flame, steam, crackling wood sound, smartphone control) — sixty to one hundred twenty thousand.

Total kit: from thirty-five thousand (budget) to two hundred forty thousand rubles (premium). The optimal price-quality combination is fifty to ninety thousand.

Conclusion: A fireplace for every home

polyurethane stucco fireplacemakes the dream of a home hearth accessible to apartment dwellers, homes without chimneys, spaces where a real fireplace is physically or economically impossible. Visually indistinguishable from stone or plaster, a polyurethane portal creates classic architecture, a noble backdrop for an electric fireplace or a false fireplace with decorative filling. Installation over a weekend, cost dozens of times lower than a real fireplace, safety when following simple rules, the possibility of repainting, relocation, adaptation to any interior — the combination of advantages makes polyurethane the material of choice for modern fireplace projects.
