The 'light room' in Russian tradition is not just a room, but a special space filled with light, air, and handcraft. Here, women spun, embroidered, wove, gathered for conversation and work. The light room was the brightest room in the house, with large windows facing south or east. Its interior was distinguished by lightness, elegance, delicate finish — not massive logs and beams, but thin strips, carved details, airy carving.
Modern interpretation of the light room — this is a space where light and lightness prevail. And here, the key role is played by thin-sectioned strips:wooden strip 20×40, 10×30, 10×40. They create a delicate, graphic pattern, do not overload the space, allow light to pass through, and contribute to creating the very airiness characteristic of the light room.
Choosing the strip section is not a matter of chance. Each size has its purpose, its area of application, its mounting and finishing characteristics. The 20×40 mm strip is a universal option suitable for most tasks. The 10×30 mm strip is for the most delicate, lace-like compositions. The 10×40 mm strip is for creating a thin but expressive vertical rhythm.
In this article, we will examine standard trim sections for the light room, determine where to use each size, how to properly join elements, what finish to choose, and how to cut the material without waste. This is a practical guide for those who want to create an interior in the spirit of the Russian light room — light, bright, elegant.
Standard cross-sections
When referring to strips, one means a rectangular section, where one dimension (thickness) is usually smaller than the other (width). Standard sections developed historically and are dictated by the dimensions of lumber from which strips are made, as well as by the practice of their use in construction and finishing.
The 20×40 mm strip: the golden middle. This is the most popular section for interior work. The 20 mm thickness provides sufficient strength and stability — the strip does not bend or warp when properly dried. The 40 mm width is optimal for creating a visual rhythm: not too thin (to avoid disappearing), not too wide (to avoid appearing bulky).
The 20×40 mm strip holds fasteners well. A 3.5×45 mm self-tapping screw can be screwed in at an angle and will hold securely. When mounted with adhesive, the 20 mm thickness provides sufficient contact area with the base. At the same time, the strip is light enough to avoid creating excessive load on the wall.
Visually, the 20×40 mm strip is perceived as elegant but not fragile. It creates a clear line, is easily readable from a distance of 2-3 meters (typical perception distance in a room). Depending on orientation — vertical or horizontal — it can create different effects: vertically installed, it raises the ceiling; horizontally — it expands the space.
The 10×30 mm strip: for delicate compositions. This is the thinnest of the considered strips. The 10 mm thickness is the minimum required to maintain strength at a length of 2-2.5 m (standard trim length). The 30 mm width is a compromise between visibility and lightness.
wooden strip 10×30It creates a very light, almost graphic pattern. It is suitable for small rooms, where heavier strips would appear excessive. For creating frequent rhythms (spacing between strips 20-30 cm), when a rich texture is needed but without heaviness.
This strip requires more careful handling during installation. It may split if a self-tapping screw is screwed in too close to the edge. It may bend if the span between mounting points exceeds 60-70 cm. Therefore, for 10×30 mm strips, adhesive mounting or very frequent fastening points are usually used.
The 10×40 mm strip: thin vertical. A middle option between 10×30 and 20×40. The 10 mm thickness — like the previous one — provides lightness. The 40 mm width — like the first — provides expressiveness.wooden strip 10-40Especially good for vertical compositions, where visible width is important while minimizing projection from the wall.
When installed vertically, this strip creates slender lines that visually raise the ceiling without creating a sense of bulk. When installed horizontally, it is less stable due to its small thickness, so it is used less often or with more frequent fastening.
The 10×40 mm strip is good where you need to create an accent wall with a pronounced vertical rhythm, while still preserving the lightness and airiness characteristic of the light room. It allows more light to pass between the strips (due to its small thickness), creating an interesting play of light and shadow.
Comparison of parameters. For clarity, we will summarize the characteristics in a table:
| Section | Thickness (mm) | Width (mm) | Weight (kg/m) | Main application | Installation Difficulty |
|---|---|---|---|---|---|
| 20×40 | 20 | 40 | 0,38 | Universal | Medium |
| 10×30 | 10 | 30 | 0,14 | Decorative | High |
| 10×40 | 10 | 40 | 0,19 | Vertical Panels | Medium |
Weight calculated for pine with density 480 kg/m³
Standard length. Most manufacturers produce rails of standard length 2.2–2.5 m. This is dictated by the dimensions of lumber and ease of transportation. For high rooms (ceilings 3 m and above) you can order rails 3 m long, but they will cost more, as they are made from longer blanks, which are less available on the market.
At a ceiling height of 2.7 m (the most common in modern apartments), a 2.5 m rail can be used to create one vertical panel from floor to ceiling without joints. This is the ideal option, as the absence of joints along the length makes the composition more cohesive and clean.
Wood species. For interior rails in a sunroom, traditionally light-colored species are used: pine, spruce, birch, linden. Pine is the most accessible and practical, with a pleasant resinous aroma and light golden color. Birch is denser, almost white, and suits painting well. Linden is the softest, easy to work with, but less resistant to mechanical impacts.
For a sunroom, oak or beech would be excessive — they are too dark and heavy for a light, airy space. These species are better suited for formal rooms, offices, libraries, where solidity and sturdiness are important.
Where to use each section
Each rail size has its optimal application area. Understanding this allows selecting the right section for a specific task, avoiding mistakes, and achieving maximum aesthetic and functional effect.
20×40 mm rail: universal solutions. Accent wall in the living room or bedroom — the most common application. Vertical rails with 40–50 cm spacing create an expressive rhythm, zone the space, and serve as a backdrop for furniture. Wall behind the bed headboard, behind the sofa, behind the TV — classic locations for 20×40 mm slat panels.
Horizontal panels at 100–120 cm from the floor (height of chair back) — traditional solution for dining rooms and entryways. Horizontal 20×40 mm rails create a protective band that protects the wall from dirt and scratches from chair backs. At the same time, they are decorative, create wall divisions, and add structural depth to the interior.
Grid for hidden mounting of pictures, shelves, mirrors. Horizontal 20×40 mm rails installed on the wall with 40–60 cm spacing create a reliable base to mount various decorative elements without drilling into the wall at each new location. This is especially convenient if walls are plastered or covered with gypsum board.
Frame for lath panels. 20×40 mm rail is ideal for creating frames, within which lath panels made of plywood, MDF, mirrors, or fabric are installed. The 20 mm thickness allows routing a groove for inserting the lath or mounting it flush.
10×30 mm rail: lightness and airiness. Decorative grids in window openings — a modern interpretation of traditional shutters. Thin 10×30 mm rails, crossed at 45 or 90 degrees, create a light grid that allows light to pass through while creating privacy, partially obscuring the view from inside.
Ceiling panels in small rooms. In a sunroom with a low ceiling (2.5 m), thick rails on the ceiling will appear heavy and reduce perceived height. 10×30 mm rails installed on the ceiling with gaps create a light texture without reducing visual height. Hidden lighting can be installed between them.
Framing for mirrors, pictures, panels. Thin 10×30 mm rail creates a delicate frame that marks the boundary but does not dominate. Four rails, joined at 45 degrees, form a simple, elegant frame suitable for interiors in Russian style.
Frequent vertical rhythms in niches, cabinets, on small wall sections. When creating a rich texture on a limited area (1–2 m²), 10×30 mm rail with 15–20 cm spacing provides a rich pattern without excessive bulk.
10×40 mm rail: vertical accents. Tall vertical panels from floor to ceiling. 10×40 mm rail installed vertically with 30–40 cm spacing creates slender lines that visually raise the ceiling. The small thickness (10 mm) makes these lines light and almost graphic, which is important for a sunroom.
Partition walls not reaching the ceiling. If you need to zone space while maintaining openness, use slat partitions 180–220 cm high. 10×40 mm rails installed vertically with 20–40 mm gaps create a semi-transparent wall that divides but does not isolate.
Decorative panels on cabinet doors, kitchen furniture facades. Vertical 10×40 mm rails glued onto flat doors transform them into lath panels, adding volume and texture. The small thickness does not significantly increase furniture dimensions, which is important in small rooms.
Framing for niches, arches, openings. Vertical 10×40 mm rails are installed around the perimeter of a niche or arch, creating a frame that highlights the architectural element and makes it more expressive.
Combining sections. Interesting solutions arise when combining rails of different sections in one composition. For example, a main frame made of 20×40 mm rails (horizontal and vertical elements forming a large grid) is filled with thinner 10×30 mm rails creating a frequent rhythm within the cells. This results in a two-level composition that is rich but not overloaded.
Or vertical 10×40 mm rails alternate with narrower 10×30 mm rails: wide — narrow — wide — narrow. This creates a variable rhythm, more dynamic and interesting than uniform. Such techniques are characteristic of traditional Russian architecture, where simplicity of forms combined with rhythmic variation.
Functional applications. In addition to decorative roles, rails can perform practical functions. 20×40 mm rail is suitable for making shelves up to 60 cm long (for longer lengths, additional support is needed). 10×30 and 10×40 mm rails are too thin for shelves but can serve as dividers in drawers, holders for lightweight items (keys, ornaments), or as a frame for textile panels (fabric is stretched over the rail frame).

Joint Nodes
The beauty of slat composition depends not only on the correctly chosen section and spacing, but also on the quality of joints. A poorly executed joint — a gap, misalignment, unevenness — immediately stands out and spoils the impression. Let’s examine the main types of joints and rules for their execution.
90-degree corner joint (wall corner). When a slat panel turns from one wall to another, an internal or external corner is formed. The cleanest way to finish it is with a 45-degree cut. Both rails are cut at 45°, and their ends are joined to form a straight, clean angle.
For precise cutting, a miter saw with a rotating table is required. The angle is set precisely to 45°, the rail is secured in the clamp, and the cut is made. Important: if the wall angle is not exactly 90°, the cut must be adjusted. The actual angle is measured with a protractor and divided in half — this will be the cutting angle for each rail.
After cutting, the ends are sanded with fine sandpaper (grit 180–220) to remove burrs. The rails are joined on the wall, and the joint is coated with PVA wood glue for added strength. If there is a small gap (up to 0.5 mm), it is filled with acrylic sealant in the wood tone.
T-joint (intersection of rails). When a vertical rail intersects with a horizontal one, a T-joint is formed. There are two ways to finish it: butt joint and mitered joint.
Butt joint — the simplest. One rail (usually vertical) runs continuously, while the other (horizontal) is cut to size and attached on top or flush. The end of the horizontal rail must be perfectly flat and perpendicular. Fastening — with glue and thin finishing nails or screws, countersunk and spackled.
Mitered joint — more complex but more elegant. A groove is routed into one rail (usually vertical) to half its thickness, into which the second rail is inserted. This creates a "half-timber" connection, which is stronger and visually cleaner. Such a joint requires precise marking and a router, but the result is worth it.
Joint along the length (extending the rail). If the wall is longer than the standard rail (2.5 m), two rails must be joined. A straight end-to-end joint looks crude and may eventually separate. It’s better to make a beveled joint at a 30-45° angle.
Both ends are mitered at the same angle (e.g., 30° to the rail’s longitudinal axis), joined on the wall with a 5-10 mm overlap, glued, and secured with thin nails. A beveled joint is less noticeable than a straight one and holds better.
Place the joint not in the middle of the wall, but closer to a corner or a vertical element (door casing, pilaster), where it will be less noticeable. If there are many rails (frequent rhythm), joints on adjacent rails should be at different heights to avoid forming a horizontal line of joints.
Joint with other elements (casing, baseboards). When a slat panel abuts a door casing or baseboard, it’s important to properly finish this joint. Rails should fit tightly against the casing, without gaps. If the casing is wider than the rail, the rail simply rests against it end-on. If the casing is narrower or at the same level, a 45° bevel can be made for a smooth transition.
With baseboards, the situation depends on how high the slat panel extends. If from floor to ceiling, vertical rails are installed over the baseboard (baseboard is installed first, then rails). If the panel doesn’t reach the floor (e.g., starts at 20-30 cm height), a horizontal baseplate may be installed between the bottom of the rails and the floor, to which the rails are attached.
Adhesive vs mechanical fastening. For thin rails (10×30, 10×40), adhesive joints are preferred — they require no drilling, don’t weaken the material, and provide a clean surface without fastener marks. Use carpentry-grade PVA (Class D3 or D4, water-resistant) or polymer-based construction adhesive.
For thicker rails (20×40), a combination can be used: adhesive plus concealed mechanical fastening (finishing nails, angled screws driven from the end). This provides additional reliability, especially for vertical elements that may bear loads (e.g., if something is hung on them).
Quality control of joints. After installation, carefully inspect all joints. Quality criteria: no gaps (maximum 0.3 mm allowed), no misalignment (rails must be in one plane), no glue residue on the face. If defects are found, they must be corrected before final finishing.
Small gaps are filled with acrylic sealant or wood-colored spackle. Excess glue is wiped off with a damp cloth immediately, while still wet. Misalignments are corrected by repositioning the element. It’s better to spend time correcting now than to live with crooked joints for years.

Finishing with oil and enamel
Choosing the final finish for rails determines not only their appearance but also durability, practicality, and tactile feel. For a bright room, where naturalness and lightness are important, two types of finishes are preferred: oil (preserves wood texture) and white enamel (creates cleanliness and brightness).
Oil: natural beauty. Wood oil is a mixture based on linseed, tung, or other natural oils with added hard waxes and pigments. Oil penetrates into the wood structure to 2-5 mm, fills pores, creates a water-repellent barrier, but still allows the wood to "breathe".
Advantages of oil: highlights wood texture, making it more pronounced; creates a pleasant matte or silky surface; eco-friendly, no odor after drying; easy to refresh — simply apply a fresh coat after several years.
Disadvantages: requires regular refreshing (every 3-5 years in living spaces); less resistant to stains than varnish or enamel; may slightly smell (if linseed oil) during the first months after application.
For a bright room, oil is an excellent choice. Pine or birch rails, finished with clear or light oil, retain their natural golden or white color, and the wood texture is visible and tactile. This creates a connection with nature and the tradition of using natural materials.
Oil application process. Rails must be sanded (150-180 grit for initial sanding, 220-240 for final), cleaned of dust, and dry (wood moisture not exceeding 12%). Oil is applied with a brush, roller, or cloth in a thin, even layer along the grain.
After 15-30 minutes (time depends on wood absorption and temperature), excess oil is wiped off with a dry clean cloth. The surface is left for 24 hours to absorb and polymerize. Then a second layer is applied using the same technique. For interior rails, usually 2-3 layers are sufficient.
After full drying (48-72 hours after the last layer), the surface can be polished with a soft cloth or a special drill attachment. This removes minor imperfections in the oil film and gives a slight sheen.
White enamel: light and cleanliness. White enamel is a covering paint that completely hides wood texture, creating a smooth, even surface. For a bright room, white is especially suitable: it reflects light, makes the room feel more spacious, and creates a sense of cleanliness, freshness, and air.
Advantages of enamel: durable (10-15 years without refreshing); easy to clean; resistant to moisture and stains; creates a perfectly even surface without wood defects.
Disadvantages: hides wood texture; requires careful surface preparation (any imperfection will be visible); harder to refresh (old paint must be completely removed).
For a bright room, white enamel on rails is a classic solution. White vertical rails against a light wall background create a light, airy pattern, characteristic of Scandinavian and Northern Russian interiors.
Enamel application process. Preparation is critical. Rails are sanded (180 grit, then 220), all knots and resin pockets are removed or spackled. A wood primer (acrylic or alkyd) is applied, which seals pores, equalizes absorption, and creates a base for enamel.
After the primer dries (4-6 hours), the surface is lightly sanded with fine sandpaper (240-320 grit) to remove raised fibers and smooth imperfections. The first enamel layer is applied with a brush or roller. Important: thin layer, no drips.
After the first layer dries (as indicated on the can, usually 4-12 hours), the second layer is applied. For white enamel, usually two layers are sufficient. If the wood is dark or knotty, a third layer may be needed for full coverage.
Colored enamels. Besides white, for a bright room, light pastel tones are suitable: cream, light gray, pale blue, soft green. These colors retain lightness and brightness but add nuance and individuality.
Important: bright, saturated colors (blue, red, green) are not typical for a bright room. They can be used accentually, in small quantities (e.g., one rail out of ten painted in a contrasting color), but not as a primary tone.
Combined finish. An interesting effect is achieved by combining oil and enamel in one composition. For example, vertical rails are coated with clear oil (pine texture is visible), while horizontal crossbars are painted with white enamel. Or vice versa. Such a combination creates a contrast of textures, adds complexity and depth to the composition.
Care for the finish. Oil coating: wipe with dry or slightly damp cloth, avoid abrasives and aggressive cleaning agents. Every 3-5 years, apply a fresh layer of oil (surface is cleaned, lightly sanded, then oil is applied).
Enamel coating: wash with a damp cloth using a mild soap solution; non-abrasive cleaners may be used. Refresh paint as needed when scratches appear (typically every 7-10 years): light sanding, primer, 1-2 layers of fresh enamel.
Cutting without waste
Material savings is not only a budget issue, but also an ecological and respectful approach to wood. Proper cutting minimizes waste and maximizes use of purchased material. This is especially relevant for rails sold in standard lengths (2.2–2.5 m).
Material quantity calculation. Before purchasing, accurately calculate how many rails are needed. For vertical panels: measure wall length and ceiling height. Divide wall length by rail spacing to get the number of rails. Ceiling height determines the length of each rail.
Example: wall 4 m, ceiling 2.7 m, rail spacing 40 cm. Number of rails: 4 m ÷ 0.4 m = 10 pieces. Length of each: 2.7 m. Standard rail — 2.5 m. Not suitable; need 3 m rails or jointing two short ones. If using 2.5 m rails, joints will be required — undesirable for verticals.
Solution: either order 3 m rails (30 cm waste per rail, but no joints), or adjust the design (panel not from floor to ceiling, but 2.2 m high, then standard 2.5 m rails with slight surplus will fit).
Optimizing cutting for horizontal elements. For horizontal rails, the situation is simpler. Wall length 4 m, standard rail 2.5 m. From one rail, you can get a 2.5 m piece (remaining wall 4 - 2.5 = 1.5 m covered by the second piece). Waste from two rails: (2.5 - 1.5) = 1 m.
If there are several horizontal rows on the wall (e.g., 3 rows), from one 2.5 m rail you can cut: one 2.5 m piece (for first row); from the second rail: 1.5 m (for first row) + 1 m (remainder). From the third rail: 2.5 m (for second row). From the fourth: 1.5 m (for second row) + 1 m. And so on.
1 m scraps accumulate. If panel height, for example, is 2.2 m, and you have 1 m scraps, two scraps can be combined to make a 2 m vertical rail, adding a 0.2 m joint from another scrap. Not perfect, but better than discarding.
Using short scraps. Scraps 30–100 cm long do not need to be discarded. They can be used for: making small frames (for mirrors, photos); making shelves up to 60 cm long; horizontal crossbars in rail compositions; repair reserve (if a rail gets damaged, it can be replaced from scraps).
Scraps under 30 cm can be used for fireplace kindling (if available), crafts, or as padding for fragile items. Very small scraps (under 10 cm) — for compost (if wood is not treated with toxic substances).
Planning with standard length in mind. The most effective way to minimize waste is to plan panel dimensions according to standard rail lengths. If standard is 2.5 m, plan panel height at 2.4 m (leaving 10 cm for trimming and error). Or 1.2 m (two pieces from one rail). Or 80 cm (three pieces from one rail).
For horizontal elements, plan segment lengths as multiples of convenient numbers: 1.25 m (two pieces from 2.5 m rail), 1.2 m (two pieces with 10 cm remainder), 80 cm (three pieces). This minimizes waste.
Combining cross-sections for savings. If a project uses rails of different cross-sections, purchase can be optimized. For example, need vertical 20×40 mm rails 2.7 m long and horizontal 10×30 mm rails 1 m long. Verticals ordered 3 m long (30 cm waste). Horizontals — standard 2.5 m, from one rail you get two 1 m pieces and 0.5 m remainder.
The 0.5 m remainder from horizontal rails can be used as short inserts or decorative elements. The 30 cm remainder from verticals — for horizontal crossbars in places where long lengths are not required.
Cutting optimization programs. For complex projects with many parts of different lengths, cutting optimization programs can be used. These are available online (free cutting calculators) and as specialized software (for professionals).
You input: standard length of raw material (2.5 m), list of required cuts with length and quantity. The program calculates the optimal cutting layout with minimal waste and outputs a cutting map: which rail to cut which pieces from.
Marking and tracking. To avoid confusion during cutting, a marking system is needed. On each rail (at the end), write its number according to the cutting map with a pencil. The map indicates: Rail #1 — cuts of 2.7 m + 0.3 m. Rail #2 — cuts of 1.2 m + 1.2 m + 0.1 m. And so on.
After cutting, all pieces are grouped: verticals separately, horizontals separately, scraps separately. Each group is tied together or stacked. This simplifies installation and prevents losing small parts.
Conclusion: the ease of tradition
Svetlica is not just a room, but a philosophy of space where light, air, and lightness are paramount. A modern svetlica in an urban apartment or country house is a space where one can retreat, engage in creativity, and rest from the bustle. And the right choice of trim — small-section rails — helps create this atmosphere.
20×40 mm rail — a universal tool for most tasks. 10×30 mm rail — for the most delicate compositions. 10×40 mm rail — for expressive vertical accents. Each finds its place, creates its own effect, contributes to the overall idea of light, airy, traditional Russian space.
Quality of execution — in the details. Precise joints without gaps, proper finish (oil or enamel), economical cutting without unnecessary waste — all these are signs of professional work, respect for material and tradition.decor in Russian styleRequires no less skill than any other style, perhaps even more — because here, it’s not about boldness, but depth; not effect, but substance.

Frequently asked questions
What profile of board to choose for accent wall in the bedroom?
For the bedroom, the optimal board is 20×40 mm or 10×40 mm (if you want a lighter effect). The wall behind the bed headboard is a classic place for board paneling. Vertical boards with a 40-50 cm spacing create a calm rhythm that does not disturb sleep. Color — natural wood with oil or white enamel.
Can 10×30 mm boards be used for vertical panels 2.7 m high?
Yes, but with frequent mounting points. A thin 10 mm board 2.7 m long may sag under its own weight. It needs to be mounted at a minimum of three points along the height (bottom, middle, top), preferably with glue along the entire length. Or choose 10×40 or 20×40 mm boards — they are stiffer.
How much do boards of different profiles cost?
Estimated prices (per linear meter, spruce, planed, dry): 20×40 mm — 350-450 rubles; 10×30 mm — 180-250 rubles; 10×40 mm — 220-300 rubles. Prices depend on the wood species, region, and order volume. Birch is 20-30% more expensive than spruce, oak — 3-4 times. Boards with factory finish (primer, paint, oil) are 40-60% more expensive than planed boards.
How to mount thin 10×30 mm boards without splitting them?
Use glue (woodworker's PVA or construction polymer) — this is the safest method. If mechanical fastening is needed, use finishing nails 1-1.2 mm thick, 25-30 mm long, driven no closer than 15 mm from the board edge. Pre-drilling with a 0.8-1 mm drill bit reduces the risk of splitting.
Is it necessary to treat boards with antiseptic before oiling?
In residential spaces with normal humidity, antiseptic is not mandatory but recommended for longevity. Use water-based impregnating antiseptics compatible with subsequent oil finish. Apply to dry wood in 1-2 coats; after full drying (24-48 hours), apply oil.
What is the oil consumption per 10 linear meters of boards?
For 20×40 mm boards: surface area is approximately 0.8 m² per 10 m.l. (including ends and edges). Oil consumption — 100-150 ml/m² in 2 coats. Total: 80-120 ml per 10 m.l. For 10×30 and 10×40 boards — roughly half as much (they are thinner). One liter of oil will cover 60-80 m.l. of 20×40 mm boards.
How to calculate the number of boards for a 4×2.7 m wall with 40 cm spacing?
Wall length 4 m, spacing 40 cm between board centers. Number of boards: 4 m ÷ 0.4 m = 10 pieces. Height of each board 2.7 m. Total: 10 boards × 2.7 m = 27 linear meters. Accounting for cutting allowance (5-10%), order 30 m.l. If standard board is 2.5 m, 12 pieces are needed (2 for allowance and cutting).
Can already installed boards be painted, or should they be painted before installation?
It is better to paint before installation — this ensures even coverage on all sides, including ends and edges. However, painting after installation is possible if boards are installed with gaps (then the brush can pass between them). If boards are installed tightly, painting the back and sides is impossible — they should have been painted before installation.
What tools are needed for installing board paneling?
Minimum set: circular saw (for precise cutting at desired angle), drill or screwdriver (for mounting the frame), level (for checking vertical/horizontal alignment), tape measure, pencil, square. Recommended: laser level (for quick marking), glue gun (if installing with glue), stapler (for temporary fixation).
How long does it take to install board paneling on a 4×2.7 m wall?
For an experienced craftsman: marking and installing the frame — 2-3 hours, installing boards (10 vertical with 40 cm spacing) — 3-4 hours, inspection and fitting — 1 hour. Total: one working day (6-8 hours). For a beginner — 1.5-2 times longer. Painting (if done after installation) — another 2-3 hours for two coats with intermediate drying.
