- Conclusion: An Informed Choice with STAVROS
You're standing in a hardware store, facing two seemingly identical ceiling rosettes. One costs 450 rubles, the other 1200. The salesperson shrugs: the first is made of foam, the second of polyurethane. Both are white, both have the same acanthus leaf ornament, both are 50 centimeters in diameter. What's the difference? Is it worth paying almost three times more?
Questionfoam or polyurethane moldingthousands of buyers ask daily. At first glance, the materials are similar—both are lightweight white plastics, both are installed with adhesive, both can be painted with water-based paint. But their physical properties, durability, application areas, and final results after a year of use differ drastically.
Foam is cheaper, more accessible, lighter. Polyurethane is stronger, more durable, more detailed. Where's the compromise? When is saving justified, and when will it lead to disappointment? How can you tell if you're looking at quality polyurethane or disguised foam? We break down the materials to their molecules, compare characteristics with numbers, and provide recommendations for specific situations.
Chemistry and structure: what's inside the materials
Understanding the differences begins with chemical composition and physical structure. Both materials are polymers, but they belong to different classes with opposite properties.
Foam: air bubbles in a shell
Polystyrene foam (expanded polystyrene, EPS) — styrene granules foamed with a gas-blowing agent, sintered into a single mass. Imagine millions of microscopic spheres, each a shell 0.01 millimeters thick, filled with air. The spheres are bonded to each other in a chaotic order. Voids remain between the spheres — open pores where air freely circulates.
Density 15-35 kilograms per cubic meter. This means: one cubic meter of polystyrene foam weighs 15-35 kilograms, the rest (1000 minus 15-35 = 965-985 kilograms) is air. The material consists of 96-98 percent air, 2-4 percent polystyrene.
Visible structure — a cross-section of polystyrene foam shows individual granules 3-8 millimeters in size, stuck together. Micro-gaps exist between the granules. The surface is rough; when sanded, entire granules tear out, leaving pits.
Low strength — squeeze a piece of polystyrene foam with your fingers, you'll hear a crunch — that's the sphere walls breaking. The material deforms irreversibly, forming a dent. Hit it with a hard object — a deep dent or puncture will remain.
Excellent thermal insulation — the air inside the spheres does not move, thermal conductivity is minimal (0.033-0.040 W/m·K). This is the primary application of polystyrene foam — insulation for facades, roofs, floors.
Our factory also produces:
Polyurethane: an ordered polymer network
Polyurethane (PU, PUR) — the result of a chemical reaction between a polyol and an isocyanate, forming a three-dimensional polymer network. The molecules are not just glued together but chemically bonded into a single array. The structure is amorphous — there are no separate granules, spheres, or fibers. It is a homogeneous monolithic plastic.
Density 180-400 kilograms per cubic meter depending on type (foamed light, cast medium, rigid dense). For interior molding, cast polyurethane with a density of 280-350 kilograms per cubic meter is used. This is 10-15 times denser than polystyrene foam.
Invisible structure — a cross-section of polyurethane is smooth, homogeneous, like plastic. There is no granularity or porosity. When sanded, the surface yields a smooth matte plane without tears or pits.
High strength — impossible to compress with fingers, the material is hard. Hit it with a hammer — a faint mark remains or nothing at all; the material springs back, absorbing the impact. Bend it — it returns to its original shape (if thickness is up to 10 millimeters). It can only be broken by applying significant bending force to a thin element.
Weak thermal insulation — the material is dense, thermal conductivity is 5-8 times higher than polystyrene foam. Not used as insulation, only as a structural and decorative material.

Extruded polystyrene: the middle ground between extremes
Sometimes, molding made from extruded polystyrene (XPS, extruded polystyrene foam) is found on the market. This is not polystyrene foam, although chemically it is the same polystyrene. It is produced by extrusion — a polystyrene melt with gas is forced through a die, forming a homogeneous fine-celled structure.
Density 28-45 kilograms per cubic meter — 1.5-2 times higher than polystyrene foam, but 7-10 times lower than polyurethane. The structure is fine-celled, with cell sizes of 0.1-0.2 millimeters, closed (air does not circulate between cells). The cross-section is smooth, resembling fine-pored rubber.
Medium strength — higher than polystyrene foam (does not crumble, harder to dent), lower than polyurethane (dents remain from strong pressure). High moisture resistance — closed cells do not absorb water. Detail of relief is better than polystyrene foam, worse than polyurethane.
Price between polystyrene foam and polyurethane — 30-50 percent more expensive than polystyrene foam, 1.5-2 times cheaper than polyurethane. An intermediate option, a compromise between price and quality.
Comparative analysis of characteristics: numbers versus emotions
Abstract descriptions are of little help. Concrete numbers, clear comparisons, and measurable parameters are needed.
Mechanical compressive strength
Polystyrene foam with a density of 25 kg/m³: compressive strength at 10% deformation — 0.1-0.15 MPa (megapascals). This means: to compress a 10×10 centimeter polystyrene foam cube by 1 centimeter (10% of its height), a load of 10-15 kilograms is needed. Accidental hand pressure, leaning furniture, dropping a tool — all leave dents.
Polyurethane with a density of 300 kg/m³: compressive strength at 10% deformation — 20-30 MPa. To compress a 10×10 centimeter cube by 1 centimeter, a load of 2000-3000 kilograms is needed. Deformation by human effort is impossible.
Difference in strength: polyurethane is 150-200 times stronger than polystyrene foam in compression. Practically: a polystyrene foam cornice will dent if accidentally touched during installation or cleaning. A polyurethane one will not be damaged even with strong pressure.
Flexural and breaking strength
Polystyrene foam: flexural strength limit 0.15-0.25 MPa. A cornice strip 10 centimeters wide, 2 centimeters thick, 2 meters long will break under a load of 3-5 kilograms applied at its center. Lifting a long strip by one end — it will snap under its own weight and the weight of the air.
Polyurethane: flexural strength limit 30-50 MPa. A similar strip will withstand a load of 200-300 kilograms at its center. Lifting it by the edge, holding it horizontally, bending it into an arc — the shape is preserved, no break occurs.
A 200-fold difference. Practically: a polystyrene foam rosette 60 centimeters in diameter, 15 millimeters thick breaks if lifted by the edge — the center sags, the ornament cracks. A polyurethane one can be lifted from any point, dropped on the floor — and remain intact.
Impact resistance
Polystyrene foam: a test with a 500-gram steel ball dropped from a height of 1 meter creates a puncture 15-25 millimeters deep, 30-40 millimeters in diameter. The material crumbles, granules fly out. A punch with a fist will pierce through an element 20-30 millimeters thick.
Polyurethane: the same ball leaves a dent 1-3 millimeters deep, which partially recovers (the material is elastic, springs back). A punch with a fist leaves no visible damage on an element thicker than 10 millimeters.
Practically: polystyrene foam baseboards get damaged by mops, vacuum cleaners, feet, children's toys, and pets' paws. Polyurethane ones withstand all of the above without a trace.
Detail of relief
The material's ability to reproduce fine details of an ornament depends on its structure. Polystyrene foam: a grain size of 3-8 millimeters limits the minimum size of an ornament element. A groove 2 millimeters deep and 1 millimeter wide (a thin furrow between leaves, a vein on a petal) cannot be formed—the material tears out in granules, the edge is ragged. The minimum element size is 5-7 millimeters.
Polyurethane: the homogeneity of its structure allows reproducing elements as small as 0.5 millimeters. The finest leaf veins, eyelashes on angelic faces, notches on shells—everything is conveyed with jewelry-like precision. The casting mold is made with an accuracy of 0.1 millimeters, and polyurethane fills it completely, copying every micro-irregularity.
Visually: polystyrene foam decor looks simplified, the ornament is conventional, generalized, resembling a child's drawing—it's clear it's a leaf, but without details. Polyurethane decor is photorealistic—veins, serrations, volume, play of light and shadow are visible. It resembles a sculptor's carving.
Moisture resistance and hygroscopicity
Polystyrene foam: open pores between granules allow water to penetrate inside via capillary action. Water absorption is 1-4 percent after 24 hours of full immersion. It sounds minor, but it's critical: water inside expands when freezing, rupturing bonds between granules, and the material crumbles. In bathrooms, kitchens, on facades (condensation, rain, snow), polystyrene foam gradually deteriorates.
Plus: water dissolves residues of porofor (the gas that foamed the granules), the material emits an odor, yellows, loses shape (granules shift apart).
Extruded polystyrene: closed cells do not let water through. Water absorption is 0.2-0.4 percent over 24 hours — 10 times lower than foam plastic. Can be used in damp rooms, but not on facades (frost will still destroy it after several cycles).
Polyurethane: monolithic structure is absolutely waterproof. Water absorption is less than 0.1 percent after 30 days of immersion. Water does not penetrate inside, does not alter properties. It can be washed, used in pools, saunas (up to +80 degrees), on facades (frost resistance F100—100 freeze-thaw cycles without loss of properties).
Temperature stability
Polystyrene foam: softens at +75-80 degrees, deforms irreversibly. Direct sunlight through a window (surface temperature up to +60-70 degrees) causes sagging. Cannot be used near powerful incandescent lamps (100-150 W), halogen lights—heat melts polystyrene foam.
At sub-zero temperatures, it becomes brittle, cracks. Facade use is excluded—in winter, the element freezes through, becomes brittle like glass, wind load breaks it.
Extruded polystyrene: withstands up to +75 degrees without deformation, better than polystyrene foam, but insufficient for all situations. More resistant in frost, but at -30-40 degrees also brittle.
Polyurethane: operating range from -60 to +90 degrees. Does not soften in the sun, does not become brittle in frost. Can be used everywhere—from a bathhouse to a freezer, from a facade in Yakutia to a sauna. Versatility.
Durability under real conditions
Polystyrene foam inside a dry room at +18-22 degrees, without direct sun, without mechanical impact: service life 10-15 years. Then yellowing begins (ultraviolet destroys polystyrene even from reflected light), granules crumble at edges, loss of ornament clarity.
Polystyrene foam in a damp room (bathroom, kitchen): 5-7 years until visible deterioration—yellow spots, granule delamination, deformations.
Polystyrene foam on a facade: 1-3 years until critical damage—cracks, crumbling, complete disintegration into granules.
Extruded polystyrene inside: 15-20 years. In damp rooms: 10-12 years. On a facade: 5-7 years (better than polystyrene foam, but not comparable to polyurethane).
Polyurethane inside: 30-50 years without loss of properties. Does not yellow, deform, or lose detail. Manufacturers' warranty period is 15-25 years, actual is much longer. In damp rooms: the same 30-50 years. On a facade: 20-30 years, then repainting is recommended, the material itself remains intact.
Price: the main argument for polystyrene foam
Polystyrene foam is the cheapest material for decor. A ceiling cornice 80 millimeters wide made of polystyrene foam: 80-150 rubles per 2-meter strip. A rosette 50 centimeters in diameter: 250-450 rubles.
Extruded polystyrene: similar cornice 150-280 rubles per 2 meters. Rosette 50 centimeters: 450-700 rubles.
Polyurethane: cornice 350-700 rubles per 2 meters (3-5 times more expensive than polystyrene foam). Rosette 50 centimeters: 900-1500 rubles (3-4 times more expensive than polystyrene foam).
But! Calculating the total project cost changes the picture. A room of 20 square meters, perimeter 18 meters. A ceiling cornice is needed—18 meters, 9 strips of 2 meters each.
Polystyrene foam: 9 strips × 120 rubles = 1080 rubles for material. After 5 years, deterioration begins—replacement needed. Another 1080 rubles. After 10 years, another 1080. Total over 15 years: 3240 rubles.
Polyurethane: 9 strips × 500 rubles = 4500 rubles for material. Service life 30-50 years. No replacement needed in 15 years. Total: 4500 rubles.
Plus installation costs. Polystyrene foam cornice is fragile; during installation, edges break, requiring purchase of 1-2 extra strips for trimming and defects. Polyurethane is strong, installs without waste. Savings on overconsumption 10-15 percent.
Conclusion:polyurethane molding versus polystyrene foam moldingis 200-250 percent more expensive at purchase, but more cost-effective when calculated over its service life.
Areas of application: where polystyrene foam is appropriate, where polyurethane is mandatory
Materials are not universal. There are situations where polystyrene foam is acceptable. There are conditions where only polyurethane will do.
When polystyrene foam is permissible
Temporary repair, short service life. Apartment for rent, planning to sell in 2-3 years, office for the duration of the lease (5-year contract) — foam decor will last through this period. Savings are justified — why pay for durability you won't use.
Decorations for events, photo zones, theater sets, exhibition stands. Needed for a day, week, month. Foam is lightweight (easy to transport, install-dismantle), cheap (not a pity to throw away after), cuts quickly (can create complex shapes on-site). Ideal material for short-term projects.
Children's creativity, modeling, teaching design basics. A child creates a palace model, an architecture student makes a building model — foam is easily cut with a utility knife, glued, painted. Cheap, accessible, safe.
Invisible structural elements. Need a substrate for a stretch ceiling to level the surface, fill voids in a frame, thicken a wall. Foam as a structural material works fine — carries no decorative function, hidden from view, not subject to mechanical impact.
When polyurethane is mandatory
Residential premises for long-term use. Your house, apartment where you live for years, will pass to children — only polyurethane. Renovation is done once every 10-15 years, decor must last this period without losing appearance.Foam vs polyurethanein this category — there is no choice, only polyurethane.
Wet areas: bathrooms, toilets, kitchens, pools, saunas (up to +80 degrees), laundries, showers. Foam deteriorates from moisture in 5-7 years. Polyurethane is completely moisture-resistant, decades without changes.
Facade decor: cornices, moldings, window and door trims, pilasters, balusters, columns on a building facade. Foam on a facade is a disaster, deterioration in 1-3 years. Facade polyurethane (with UV stabilizer) lasts 20-30 years.
High-traffic areas with high mechanical load: corridors, hallways (baseboards hit by shoes, bags, vacuum cleaners), children's rooms (toys, balls, activity), living rooms with pets. Foam cannot withstand, gets dents, chips. Polyurethane is impact-resistant.
Areas with decorative lighting: near powerful lamps, halogen lights, spotlights. Foam melts. Polyurethane is heat-resistant.
Complex decorative elements with fine ornamentation: Baroque rosettes with detailed relief, column capitals with acanthus leaves, stucco panels with figures, friezes with fine ornamentation. Foam does not reproduce details, ornament appears blurred, coarse. Polyurethane conveys every line.
Elements subject to bending or twisting: flexible moldings for curved surfaces (round columns, arched openings, bay windows), elements on uneven walls. Foam breaks when attempting to bend. Polyurethane (special flexible type) bends to a radius of 30-50 centimeters.
Extruded polystyrene: a compromise
Suitable for dry interior areas with medium load: living rooms, bedrooms, studies in apartments and offices. Stronger than foam (will withstand accidental touches, cleaning), 30-40 percent cheaper than polyurethane. Service life 15-20 years — sufficient for most renovations.
Not suitable for wet areas (though better than foam, but not ideal), facades (insufficient frost resistance), complex decor (detailing limited). Intermediate choice for a limited budget under adequate operating conditions.
How to distinguish polyurethane from foam when purchasing
Problem: unscrupulous sellers pass off foam as polyurethane or use vague terms like "polymer stucco" without specifying material. Price set between foam and polyurethane. Buyer thinks they're buying polyurethane at a discount, but gets foam at triple the price.
Visual signs
Cut (element end): foam shows granular structure — individual granules visible, gaps between them. Polyurethane smooth, uniform, like plastic. Extruded polystyrene fine-porous, cells 0.1-0.2 millimeters, resembles frozen dishwashing foam.
Scratch the back (invisible) side of element with fingernail. Foam crumbles into granules, leaves deep groove. Polyurethane doesn't scratch or leaves barely noticeable mark. Extruded polystyrene scratches but doesn't crumble, groove shallow.
Ornament detailing: examine small elements — leaf veins, edge serrations, transitions between planes. Foam — elements simplified, coarse, transitions sharp, small details absent or blurred. Polyurethane — details clear, transitions smooth, finest nuances visible.
Color: foam white matte, slightly grayish (due to air inside light scatters). Polyurethane white, may be slightly creamy or warm tint (depends on additives), but color dense, deep. Extruded polystyrene white or colored (blue, pink, green — dyes added to distinguish from foam).
Tactile signs
Weight: weigh in hand or ask for scales. Foam cornice 2 meters long, 80 millimeters wide weighs 60-100 grams. Polyurethane similar one 400-600 grams. Difference of 5-8 times noticeable. Extruded polystyrene 120-180 grams.
If no scales, compare sensation: foam almost weightless, like empty cardboard box. Polyurethane has noticeable mass, like piece of dense plastic.
Compression: carefully squeeze element with fingers from both sides (not in seller's view — may not appreciate). Foam indents, leaves dent, crunch audible. Polyurethane hard, doesn't deform. Extruded polystyrene indents slightly, dent small.
Bending: take thin element (molding, baseboard) by ends, carefully bend. Foam breaks or cracks when bent 10-15 degrees from straight line. Polyurethane bends 20-40 degrees without damage, returns to straight shape. Extruded polystyrene bends 10-20 degrees, slight deformation remains.
Documentary signs
Request the product certificate or passport. It must specify: material — polyurethane (PU, PUR), density (for molding at least 200 kg/m³, preferably 280-350), manufacturer, standard (European manufacturers indicate EN standards).
If the seller refuses to show documents or says "polymer," "plastic," "decorative material" without specifics — it is foam or extruded polystyrene.
Price is an indirect indicator. If a cornice costs 100-200 rubles for 2 meters — it is definitely not polyurethane. If 600-800 and above — likely polyurethane. If 250-400 — most likely extruded polystyrene or overpriced foam. Check visually.
Installation: differences in technique
All materials are glued with polymer adhesives, but there are nuances.
Foam and polystyrene
Light weight allows the use of medium-fixation adhesives — standard liquid nails. Adhesive is applied in dots or a serpentine pattern with a spacing of 10-15 centimeters. The element is pressed against the wall for 20-30 seconds. Additional fixation is not needed — weight is low, adhesive holds.
But! Fragility requires caution. When pressing, do not apply point pressure — dents will remain. Press evenly with palms over the entire area. When cutting, use a sharp knife — a dull one will crush edges and pull out granules. Joints in corners often have gaps — material crumbles, precise 45-degree cutting is difficult. Gaps are filled with putty or sealant.
Polyurethane
Greater weight requires adhesives with fast and strong fixation — special adhesives for polyurethane molding, reinforced liquid nails. Adhesive is applied in a serpentine pattern along the entire length with a spacing of 3-5 centimeters. The element is pressed for 60-90 seconds until it sets.
For large heavy elements (rosettes with a diameter over 80 centimeters, cornices wider than 150 millimeters), additional mechanical fixation with screws is recommended during adhesive curing (4-6 hours). After the adhesive fully dries, screws can be removed (holes filled with putty) or left in place.
Strength allows not fearing damage during installation — you can press firmly, cut with any tools (handsaw, miter saw), tap for fitting. Joints are tight without gaps — material cuts cleanly, without tearing.
Painting and final finishing
All materials are painted with water-based paints, but preparation and results differ.
Foam
Surface is porous, paint absorbs unevenly. The first layer absorbs heavily, paint consumption is high. 3-4 layers are needed for even color. After painting, the granular structure is visible — surface does not become smooth.
Glossy paints are not recommended — gloss emphasizes granularity, looks cheap. Only matte paints.
Patination (aging effect) is difficult to perform — dark patina gets stuck in pores between granules, excess is hard to remove, result looks dirty.
Polyurethane
Surface is smooth, primed (quality manufacturers prime products at the factory). Paint applies evenly, consumption is low. 2 layers are enough for perfect coverage.
Any paints can be used — matte, semi-gloss, glossy. Gloss on polyurethane looks noble, emphasizes relief.
Patination, gilding, silvering, marble effects, wood effects — all are achievable. Smooth surface allows process control, result is professional.
Answers to popular questions about molding materials
Can foam molding be used in the bathroom?
Highly undesirable. Foam absorbs moisture, swells, loses bonds between granules, begins to crumble. Service life in bathroom is 3-5 years maximum. Extruded polystyrene is better — will last 8-12 years. Polyurethane is optimal — decades without changes.
How to glue a broken foam element?
Standard solvent-based adhesives (Moment, super glue) dissolve foam — glue area melts, turns black. Use water-based adhesives — PVA, acrylic, special for foam. But glue strength is low — element will break in the same spot under minimal load. Easier to replace the element.
Can foam be painted with acrylic paint?
Yes, water-based acrylic paint is safe for foam. Do not use solvent-based paints (nitro enamels, alkyd enamels) — solvents will melt the foam.
Does polyurethane molding yellow over time?
Quality polyurethane molding with UV stabilizers does not yellow for decades. Cheap polyurethane molding from unknown manufacturers may yellow after 5-10 years from ultraviolet light (even indoors reflected light contains UV). Check manufacturer, availability of certificates.
How much does a polyurethane rosette with a diameter of 60 centimeters weigh?
With a thickness of 15-20 millimeters and polyurethane density of 300 kg/m³ — approximately 800-1200 grams. A similar foam rosette weighs 100-150 grams. Difference is 8-10 times.
What makes polystyrene foam better than polyurethane?
Only two parameters: price (3-5 times cheaper) and weight (8-10 times lighter, which simplifies transportation for large volumes). In all other parameters, polyurethane is superior.
Can you distinguish quality polyurethane from cheap polyurethane?
Density is the main criterion. Quality cast polyurethane for molding has a density of 280-350 kg/m³. Cheap foamed polyurethane (used to reduce cost) has a density of 80-150 kg/m³ — properties are worse, strength is lower. Checked by weight and hardness — quality polyurethane is heavier, harder.
Is extruded polystyrene the same as polystyrene foam?
Chemically — yes, polystyrene. But production technology and properties differ drastically. Polystyrene foam is foamed (granules with air, sintered), extruded is pressed through a die (uniform fine-celled structure). Extruded is 1.5-2 times stronger, denser, more moisture-resistant. But still inferior to polyurethane.
Why is polyurethane several times more expensive than polystyrene foam?
Raw material cost: polyurethane components (polyol, isocyanate) are 8-12 times more expensive than styrene. Production technology: polyurethane casting requires precision molds (accuracy 0.1 millimeters, mold cost 50-200 thousand rubles), polystyrene foam is cut with a hot wire from a block (no mold needed). Density: one product uses 10 times more material by mass. Result: polyurethane product cost is 10-15 times higher than polystyrene foam.
Which material to choose for restoring a historical building?
Only high-density polyurethane (350-400 kg/m³) or plaster. Polystyrene foam is unacceptable — low durability, primitive detailing, mismatch with historical context. Polyurethane allows recreating original ornament with millimeter precision, lasts decades, visually indistinguishable from plaster molding after painting.
Conclusion: Informed choice with STAVROS
foam or polyurethane molding— it's not just a question of price, but a philosophy of approach to repair and living space. Polystyrene foam is a temporary solution, a compromise, saving now in exchange for replacement in a few years. Polyurethane is an investment, quality that will outlast more than one renovation, decor that will remain for children.
The choice depends on the specific situation. Temporary office, rented apartment, decoration for an event — polystyrene foam is justified. Your home, long-term perspective, wet rooms, facades, complex decor — only polyurethane. Extruded polystyrene is a compromise for a limited budget under moderate operating conditions.
The main thing is not to fall for substitution. Check the material visually and tactilely, request documents, compare weight. Real polyurethane with density 280-350 kg/m³ is hard, heavy, with detailed relief, smooth cut. Polystyrene foam is light, soft, grainy, with simplified ornament.
