Before finishing plastic panels necessary calculate quantity various profiles, fasteners, PVC panels and laths for sheathing. This article provides a technique that will help you determine the approximate amount of material for installation PVC panels.

Calculation of the number of rails for the sheathing:

To calculate the number of reis, you need to measure the total wall length And ceiling height in meters. Then divide the ceiling height by distance between panels(no more than 0.5 m), round the resulting number up and multiply by the total length of the walls. After this, similarly calculate the footage of the slats for window and door openings, and subtract from the resulting number.

At calculation It is necessary to take into account that the sheathing is done around the perimeter of the walls. Therefore, to the total length of the slats, you need to add two more vertical slats for each wall, the length of which is equal to ceiling height. To the resulting number you also need to add the perimeter of window and door openings.

After all calculations to the length of the yard, you need to add 5% for overlaps and cuts and round the result up to a whole number.

For convenience, below is formula for calculating the number of battens:

Where L rey – yard length, m; l – total length of the room, m; h - ceiling height, m; a – distance between panels is taken from 0.2 to 0.5 m; L pr – the length of the yard in window and door openings, m; P – perimeter of window and door openings, m; k – safety factor 5% (assumed 1.05).

Calculation of the number of plastic panels:

For calculation of PVC panels need to calculate wall area and subtract it from this window area And doors. The resulting number is divided by the area of ​​the panel. It is recommended to add 10% to the resulting figure for overlaps and cuts and round the resulting number to a larger whole number.

Below is:

Where N – number of panels, PC; l – total length of the room, m; h - ceiling height, m; S pr – area of ​​window and door openings, m 2; l pan – panel length, m; h pan – panel height, m; k – safety factor 10% (assumed 1.1).

Also number of panels can be found by dividing total length of walls on panel width. In this case number of panels for finishing the surfaces above the door, as well as above and below the windows, they are calculated separately.

Calculation of mounting profiles for plastic panels:

Mounting profiles are sold individually, the length of one piece is usually 3 m.

If installation is carried out internal and external corners, then it is necessary to measure separately the height of all external and internal corners of the room, divide the resulting dimensions by 3 m. For framing window and door openings - the sum of the perimeters of windows and doors divide by 3 m (windows are measured on four sides, doorways - on three sides, except for the bottom width), add the resulting number to the length of the outer corners. Round the values ​​of the numbers to a larger integer, the result will be the required number of corners in pieces.

If installation is carried out universal angle, which is sold by the meter, then you need to add everything up lengths of internal and external catch indoors, as well as the perimeters of window and door openings, to obtain the required length of the corner.

Calculation required number fillets. The perimeter of the ceiling is measured, the resulting number is divided by 3 and rounded to the nearest whole number. You may also need internal and external corners for the ceiling plinth, quantity which will be equal number of internal and external corners indoors respectively.

Starting profile. Quantity depends on joints with walls made of other materials. From the starting profile you need to start installing panels on each wall, so for calculation you will need the height of the corners from which the installation of the panels will begin; the resulting number must be divided by 3 m and rounded to the nearest whole number.

The construction market is constantly evolving, offering consumers inexpensive and high-quality products, so repairs can be done easily and with pleasure. Modern building materials make it possible to carry out finishing work with your own hands quickly and without the involvement of professionals. These materials include plastic panels, which are often used to decorate the ceiling in residential and office buildings.

Plastic panels are one of the cheapest options for finishing a bathroom.

The ceiling made of plastic panels is a metal or wooden frame covered with PVC lining. Plastic can have different sizes, the greatest demand is for products with a length of 2.7 and 3 m and a width of 25 and 50 cm. Inside, such panels have stiffening ribs and a hollow base, so they are light and durable. For ease of installation on the sidewalls, they have locks for docking. How to sheathe it yourself?

Plastic ceiling panels differ from similar products used for wall cladding. They are much lighter as they only have to support their own weight. Wall panels are more durable, while the ceiling panel can be damaged even by hand. Therefore, all work should be carried out with the utmost care.

Advantages and disadvantages

Finishing the ceiling with plastic panels has its positive aspects:

1. In the frame of the structure you can hide electrical wiring, ventilation and other communications.
2. Installing built-in lamps and lighting is not difficult. They are resistant to high temperatures and do not emit unpleasant odors. Therefore, the usual electrical wiring can be replaced with circuits for installing LEDs, halogen and spotlights.
3. Simple installation and dismantling process.
4. Possibility of installing additional insulation from noise, moisture, and sound into the frame.
5. Wall panels are strong, durable, plastic, moisture and fire resistant, do not fade in the sun, and are easy to clean.
6. When finishing, you can ignore the uneven surface.

Ceilings made of plastic panels also have their negative sides:

1. Cheap plastic can allow light from recessed lights to pass through.
2. The seams between the panels are visible to the naked eye.
3. There is no possibility of making a multi-level structure or bending.
4. Part of the height of the room is lost.

The frame for installing the panels must be metal, since wood quickly rots and collapses.

Types of PVC profiles

You will need not only the panels themselves, but also components. When visiting the construction market for the first time, due to the variety of PVC profiles, an inexperienced buyer may become confused. But each type has its own special purpose.

1. Starter profiles are the most commonly used. They are needed to mount the panel around the perimeter of the room on the line of the ceiling being mounted.
2. External and internal plastic corners are necessary to make beautiful joints at the corners of the room.
3. H-profiles connect the ends of several panels.
4. A plastic ceiling plinth is needed to hide the ends of the panels. This is the same starting profile, only with decorative trim.
5. F-profiles are necessary to hide the ends. They can be useful when finishing adjacent walls with various materials.

Universal plastic corners hide any joints.

Material calculation

It is better to cover the ceiling with materials of standard sizes, 5-10 mm thick and 250-500 mm wide. Typically, panels are supplied in standard lengths of 2.7-3 m, but there are also 4-meter samples.

The area of ​​each panel can be seen on the packaging. Their required number will be equal to the ceiling area divided by the area of ​​one panel. When calculating the required volume of materials, be sure to add a reserve of 15%, which will be used for scraps and scraps. So, for the ceiling you need 10 PVC slabs, adding a reserve, we get 11.5 panels (it is advisable to round up).

To calculate the amount of profile required, the ceiling area needs to be divided into strips spaced 60 cm apart: the mounting guides will be installed along them. Additionally, a rigid profile will be required for cladding the perimeter. If desired, metal profiles can be replaced with wooden sheathing, but the useful life of such a structure will be much shorter.

Ceiling plinths are sold in 3-meter segments. To calculate the required quantity, you need to divide the length along the perimeter by 3, and round the resulting number up.

Ceiling installation

Before starting work, the walls and ceiling must be checked for the presence of hidden electrical wiring. To do this, you can use a special detector or invite a professional.

Under no circumstances should you stick a plastic panel directly onto concrete - the lack of ventilation between the panel and the ceiling is unacceptable.

In order to prevent the appearance of an unpleasant odor in the room associated with the appearance of fungus or mold, the ceiling surface should be treated with an antiseptic solution. Then you need to decide on the height of the suspended ceiling. In this case, you need to take into account the dimensions of the lighting fixtures that will be installed directly in the panel. Typically, a plastic suspended ceiling is installed at a distance of 6-7 cm from the rough surface.

At the level of the drawn line, it is necessary to secure special corners under the base of the ceiling with self-tapping screws. After securing the corners along the perimeter of the line, guides are installed on them. They need to be attached directly to the rough ceiling using long self-tapping screws, and the self-tapping screw must be driven in so that its head is at the level of the line on the walls and the guide corners. The guides are attached in increments of 60-100 cm.

After this, you need to prepare the plastic panels. Using a hacksaw for metal, they need to set the desired size. The slab should be cut approximately 5 mm less than the length of the room. To obtain a perfectly smooth edge, it must be sanded with sandpaper. After this, the protective film is removed from the panels. Care must be taken not to dent the panel.

Holes for lighting fixtures are made in predetermined locations. They can be made either with a regular sharp knife or with a special attachment for a drill.

You need to take care of the supply of electrical wires to the ceiling in advance. After the lighting fixtures are inserted into the grooves prepared for them, installation of the panels can begin. They must be fastened across the profiles. The first panel slides close to the wall so that it is in the profile on three sides. The last 4th side is attached to the frame using self-tapping screws. The next panels need to be fastened in the same way, but one of the sides is fixed to the previous panel.

This requires securing all panels except the last one. Before attaching it, it is necessary to level the ceiling using guides by tightening or loosening the screws. The ceiling level should be the same everywhere.

Next you need to give the last panel the required width and insert it into the grooves.

1. 1. Measure the total perimeter of the room in meters.
2. 2. Subtract the width of windows and doors.
3. 3. Divide what happened by the width of one panel - 0.25 m.
4. 4. Add several pieces of panels to finish the openings above the doors and windows.
5. 5. You will get the required number of panels in pieces.

• You need to measure the total perimeter of the room in meters anddivide it by the length of the plinth - 3m.
• The plinth is easy to saw and the ends come together.
  
• Due to this, you can lay it to any length.

Why do you need a plastic lathing (mounting profile)

• - If the walls in the room are uneven
• - When installed in a bathroom due to high humidity
• - If it is necessary to create sound and thermal insulation
• - If the panels subsequently need to be dismantled and reinstalled in another location

• 1. Based on the height of the walls, determine the number of required levels of sheathing. Lathing
  
• installed at intervals of 30-40 cm.
• 2. Determine the total perimeter of the room in meters and multiply by the number of lathing levels.
  
• This will give you the total length of the required sheathing in meters.
• 3. Divide the total length of the sheathing in meters by 3 meters (the length of one sheathing) and round to
  
• the larger side.

• Example:
• - The height of the wall is 2.7 meters, the number of lathing levels is 7. The room is 3.5 m by 5 m.
• - It is necessary to finish around the entire perimeter. The perimeter of a room 3.5*2 + 5*2 is 17 m.
• - We multiply 17 by 7 and get 119 m - the total length of the required sheathing.
• - Divide 119 m by 3 to get 39.66, round to 40.
• - To finish this room around the entire perimeter, 40 battens are needed.

Scheme for installing panels on the sheathing

• 1. Mounting profiles are attached to the wall at a distance of about 30 cm using self-tapping screws.
• 2. Using metal clips, the internal and external corners are installed first.
• 3. The panels themselves are installed using clips.
• 4. Next, if necessary, ceiling plinths or starting profiles are installed.

Advantages of plastic sheathing over wood and metal

Installation takes less time; the panels are simply clipped to the slats.
- The plastic sheathing is not afraid of dampness, which eliminates the formation of mold and fungi.
- Plastic sheathing has a smaller width than wood or metal, only 1 cm.
There will be less loss of free space in the room.

In this article you will find answers to the following questions:

How many PVC panels and moldings (profiles) will be needed during repairs,

How much fastening materials are needed to cover the surface?

The article contains a descriptive part of the methodology for calculating the required material for covering walls with PVC panels. At the end of this article there is a file - “panel calculator”: by substituting your data in the appropriate cells, you will automatically calculate the required amount of material.

For greater clarity, the article will provide a calculation using a specific example.

1. Calculation of the total length of the slats required for the sheathing(S).

T M Decomax reminds: if the facing surface is flat and the room is dry, then the panels can be installed without lathing .

- calculation of the area for cladding with slats
S region = (l c * h c – l o * h o – l d * h d)
S region= (16.4m*2.8m – 1.3m*1.4m-2m*0.8m) = 42.5m2

- calculation of the length of the sheathing
L = S region /a
L= 42.5m2/0.4m = 106.25m

The lathing is always installed around the perimeter, so for each wall you need to add 2 slats, the length of which is equal to the height of the wall if the panels are mounted horizontally and the length of the wall if vertical.

When placed horizontally
L mountains = L+2*b* h s
L mountains=106.25m+2*4*2.8m= 128.65m

When placed vertically
L ver = L+2*b* l s
L ver=106.25m+2*2*5m+2*2*3.2m = 139.05m

Add 5% for cuts and overlaps and round the result up.
S = L mountains or L ver *1.05
- for horizontal placement: S= 128.65m*1.05=135.08m ≈ 136m
- for vertical placement: S= 139.05m*1.05=146.01m ≈ 147m

2. Calculation of the number of plastic panels (N):

N = S region / l pan * h pan
N= 42.5m/3*0.25m=56.67 pcs.

3. Calculation of mounting profiles for plastic panels:

Mounting profiles TM Decomax have a length of 2.7 m.

To determine the number of corners of a certain type you need:
- for profile " internal corner» – measure the height of all internal corners;
- for profile " outside corner» – measure the height of all external corners, and also calculate the perimeter of the window and door opening;
- for molding " universal angle» specify an angle or corner - calculate the sum of the lengths of external and internal angles;
- for profile " ceiling plinth» – measure the perimeter of the ceiling;
- for profile " starting» - calculate the sum of the heights of the corners from which installation should begin, as well as the length of the joints with walls and other materials.

4. Calculation of fasteners for mounting plastic panels:

Dowel-nails– used when installing sheathing on a brick or reinforced concrete base – consumption will be 1 pc. for every 0.5 m of mounting rail.
Nails and screws– consumption will be 1 nail per 0.3 m.
Staples (clasps)– the consumption will be 1 staple per 0.4 m.

This technique will give you the opportunity to calculate the approximate amount of required material that will be needed for the installation of PVC panels. For an accurate calculation, please contact consultants at our partner stores closest to you.

This file will allow you to automatically calculate the required amount of material for finishing the room.

Before installing PVC panels, it is necessary to calculate the number of PVC panels themselves, profiles, PVC mounting strip for sheathing and fasteners.
The calculation method given in this article will help you determine the required amount of material for installing PVC panels.

Calculation of the number of PVC mounting strips for lathing:

To calculate the required amount of PVC mounting strip for lathing, you need to measure the total length of the walls and the height of the ceilings in meters.
Then divide the height of the ceilings by the distance between the PVC mounting strips. The optimal distance is from 0.3 m - 0.5 m.
The lathing is done around the perimeter of the walls, so for each wall you need to add two PVC mounting strips, the length of which is equal to the height of the ceilings.
Please note that the PVC mounting strips are attached perpendicular to the PVC panels, i.e. If you install PVC panels vertically, then the PVC mounting strip must be installed horizontally and vice versa.
Round the resulting number up and multiply by the total length of the walls. After this, the footage of PVC mounting strips for window and door openings is calculated in the same way, it is subtracted from the resulting number, which you rounded.

For convenience, below is the formula for calculating the required number of PVC mounting strips for sheathing:

Where L rey - length of PVC mounting strips, m

l - total length of the room, m

h - ceiling height, m

a - distance between PVC panels, m (optimally - 0.3)

L pr - length of PVC mounting strips in door and window openings, m

P - perimeter of door and window openings, m

k - safety factor 5%

Calculation of fasteners (clamps) when using a PVC mounting strip:

If the sheathing is installed on a brick or reinforced concrete wall, you will need dowel-nails, the consumption of which will be 1 pc. for every 0.5 m of PVC mounting strip.
The number of clamps required for the installation of PVC panels - multiply the number of PVC panels and profiles (in pieces) by the number of rows of sheathing made from PVC mounting strips.
For example, the number of PVC panels is 10 pcs, profiles are 4 pcs, and the number of rows of sheathing is 5, then the required number of clamps is 70 pcs.
The required quantity for the ceiling is calculated in the same way.

Calculation of the number of PVC panels:

Calculate the area of ​​the walls (multiply the length of the walls by the width of the walls) then subtract from it the area of ​​the door and window openings. We divide the resulting number by the area of ​​the PVC panel.
We recommend adding 10% for overlaps and cuts and rounding the resulting figure to a higher number.

Where N - number of PVC panels

l - total length of the room, m

h - ceiling height, m

S pr - area of ​​door and window openings, m

l pan - PVC panel width, m

h pan - PVC panel height, m

k - safety factor 10%

You can also find the required number of PVC panels by dividing the total length of the walls by the width of the PVC panel. In this case, the number of PVC panels for finishing above the doorway, above and below the window is calculated separately.

Calculation of PVC profiles:

Produces and sells 3 m profiles.

Types of profiles:

If the installation is carried out using internal and external PVC corners - and the height of the room is no more than 3 meters, it is more advisable to simply count the corners in the room.
If the installation is carried out with a universal PVC corner, which is sold by the meter, then you need to add up all the lengths of the internal and external corners in the room, as well as the perimeters of door and window openings - you will get the required footage of the universal PVC corner.

Calculation of PVC ceiling plinth (fillets):

The perimeter of the ceiling is measured, the resulting number is divided by 3 (this is the length of the ceiling plinth) and rounded to the nearest whole number.

Don't forget about internal and external corners, as well as connectors for the ceiling plinth. It is very comfortable! There is no need to “cut” the baseboard at 45 degrees, which can cause a lot of trouble, because... plinth is a hollow product.
