How to calculate external wall panels for... How much will it cost to make a bathroom with plastic panels? Calculation of fasteners for mounting plastic panels
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.
In modern interiors of apartments and offices, suspended ceiling designs made of polyvinyl chloride (PVC) panels are common. This is a convenient and safe material that allows you to quickly and inexpensively update any room. Nice appearance, easy maintenance, and moisture resistance make plastic finishing advantageous when installing walls and ceilings in bathrooms, restrooms and kitchens. The design and coating of the plastic differs in texture and color palette, so you can easily select the necessary panels and decorate your home with them.
Features of polyvinyl chloride products
Plastic finishing is an economical option for transforming the appearance of walls, ceilings and the entire room. Installation of finishing does not require construction skills; anyone with accuracy and patience can handle it.
A large assortment of polyvinyl chloride finishes allows you to choose suitable options to suit your taste for an organic combination with the interior of the room. PVC panels are:
- for ceiling structures that are light in weight and elastic, but at the same time fragile and require careful handling;
- for walls with greater rigidity and weight;
- glossy with varnish;
- with a pattern on thermal film;
- with a texture imitating wood, granite, etc.
Finishing products are available in several sizes, which also needs to be taken into account when purchasing material for repairs. The main advantage of PVC panels is that they are easy to clean because they are not afraid of moisture. In addition to bathrooms and toilets, balconies, loggias, courtyard gazebos and baths are finished with polyvinyl chloride slabs. Some products are made with beautiful designs and textures, such elements can decorate the interior.
Polyvinyl chloride finishes are distinguished according to manufacturing technology and pattern application. White panels without any pattern are simple and inexpensive. But there are also products with a decorative coating applied in two ways:
- economical - transferring an ornament or design from thermal film to the surface;
- by direct printing, this method allows you to obtain high-resolution images or decor with a large color palette. Requires special equipment.
Advantages of suspended structures
There are many advantages to suspended structures made of polyvinyl chloride material:
- First of all, this is the service life. Manufacturers guarantee for 15 years. But experience and calculations show that this period is much higher. A high-quality product does not lose its properties for 20 years.
- Safe and environmentally friendly. Polyvinyl chloride is even used for children's toys, so it is considered harmless.
- Low cost. Compared to other designs, the finishing material is inexpensive and looks presentable.
- Moisture resistance. Dampness does not threaten the plastic, and the structure tolerates leaks well.
When purchasing material, you should know how many fasteners and metal structures will be required. Below are some recommendations for calculating the required number of panels and related materials.
Selection of finishes
When preparing to purchase plastic panels, you should carefully choose. The quality of the products varies; crooked elements will not decorate the interior.
We begin the selection with a careful inspection: the geometry of the products is correct and identical, the pattern is evenly distributed over the plane, without abrasions or “bald patches.”
Select panels that are smooth, without scratches, bumps or dents. If the stiffeners are visible from the front side, this is considered a defect. The number of stiffeners and their thickness give the strength of the plastic plate. The quality of the finish is affected by the rigidity of the PVC structure. When choosing, pay attention to the wall thickness. The front one should be strong and thick.
Check the connection; the connection should be easy and without gaps.
How to calculate the required number?
A simple way to calculate is to divide the area of the ceiling by the area of one piece, we get the required amount of consumables. Experienced craftsmen recommend adding 20% for fitting, trimming and culling. Since there are no windows on the ceilings, this method is the most common. For complex combined structures that combine various materials (plasterboard and plastic panels or tension fabric with slabs), the calculation is carried out for areas covered with PVC.
In cases where a suspended ceiling is planned, calculate the required number of mounting profiles and fasteners. For this purpose, it is better to schematically depict the ceiling and the location of the slabs on it. By drawing parallel lines on the wall, we will mark the installation locations for the profiles. The pitch is selected depending on the width of the panels - 500-600 mm. In addition, it is necessary to provide for the installation of a rigid UD profile around the perimeter. Following the scale according to the diagram, calculate the need for a metal profile.
To calculate the required fasteners for installing PVC products, take into account the fixation of load-bearing profiles to the ceiling, consumption - one dowel per 0.5 meter of profiles. The panels can be secured to the profiles with special screws (self-tapping screws) with a wide head, the consumption is one per 0.5 meter of the length of the slab.
If installation of ceiling plinths is planned, calculate the required length before purchasing. The standard sizes of manufactured skirting boards are three meters. Therefore, having measured and calculated the perimeter of the ceiling, divide by three and round up.
If you are making an economical repair option, then attach the products to the ceiling. Then, when calculating, you will find out the required amount of materials, limiting yourself to the first stage.
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.
Cosmetic repairs in an apartment, with the modern variety of plastic panels, is at first glance a fairly simple task. However, there are many nuances in this matter, neglect of which will certainly lead to senseless losses of money and time.
Most often, mistakes are made at the planning stage, when it is necessary to calculate the number of PVC panels. All other troubles occur during installation work. To avoid all this, to make high-quality, and, importantly, inexpensive repairs, it is recommended to take a closer look at the information below.
Advantages of PVC panels
To begin with, it is worth recalling the main advantages of finishing with plastic panels. It is the following advantages that make this type of repair very popular, and the material itself sells well:
- attractive price;
- a huge selection of colors and textures of plastic;
- simple and quick installation;
- versatility of use;
- resistance to moisture and vapors;
- ease of care;
- durability;
- quick dismantling if necessary.
Installation of plastic panels in a medium-sized room can be done in just one day, which cannot be said about ceramic tiles or decorative plaster. Even painting, taking into account drying, will take longer than finishing with plastic.
A few words about the frame
The lathing for plastic panels can be made either from a metal profile or from wooden beams. Each of these materials has its own advantages and disadvantages. They are worth listing briefly.
Advantages of a metal frame:
- mounted on almost any surface, regardless of its curvature;
- tolerates sudden changes in temperature and humidity levels;
- durability;
- does not burn;
- the metal frame can be adjusted even when already assembled.
Disadvantages of a metal frame:
- relative high cost of profiles;
- greater weight than wood.
Advantages of wooden lathing:
- cheapness;
- ease.
Disadvantages of wooden sheathing:
- can only be mounted on a relatively flat surface;
- does not tolerate changes in temperature and humidity levels;
- highly flammable;
- short service life.
Which one to choose depends, first of all, not on the price, but on the conditions in which it will serve as the basis for the plastic finish. If it is a perfectly dry and warm room with constant climate control and smooth walls, then a wooden frame will be the right choice. In other cases - only metal.
Calculation of PVC panels
What should you consider when buying plastic for wall decoration? Here three parameters are taken into account:
- perimeter of the room;
- ceiling height;
- width of one panel.
Example No. 1
The room dimensions are 5x6 meters and the desired ceiling height is 2.5 meters. Plastic panels for walls will be purchased as standard: 25 centimeters wide and 3 meters long. The corner joints will be connected using a herringbone (plastic corner). To make the correct calculation of PVC panels in this particular example, it is necessary to divide the perimeter of the room by the width of the plastic. The corner is calculated by height and number of corners.
The perimeter is: 5 x 6 = 30 meters.
Required number of panels: 30 / 0.25 = 120 pieces.
Connecting angle: 2.5 x 4 = 10 linear meters.
Example No. 2
Now the task gets more complicated. Let's say the room dimensions are 10x12 meters and the ceiling height is 3.5 meters. The width of one plastic panel is 30 centimeters and the length is 3 meters. Such parameters are typical for public spaces. For this example, in addition to the above materials, you will also need a connecting H-shaped plastic profile. Now the calculation.
The perimeter is: 10 x 12 = 120 meters.
Required number of panels: for the first row 120 / 0.3 = 400 pieces. Plus, to increase another 0.5 meter in height, you will need 400 plates of the corresponding length, which will amount to 200 linear meters of panels, or 200 / 3 ~ 67 pieces. In total, for the entire room, we have 467 panels.
The corner profile made of plastic is calculated by analogy with the previous example, that is, 3.5 x 4 = 14 linear meters. The connecting profile is calculated based on the perimeter of the room, which in this case corresponds to 120 linear meters.
For non-standard rooms, the calculation of plastic panels is carried out by analogy with the examples given.
Installation of plastic
After calculating and purchasing all the necessary materials, all that remains is the installation of PVC panels. Wall finishing usually begins when the ceiling is ready. It can be suspended, tensioned or plastic. A metal profile frame is assembled on the walls. Next, the connecting profile is fixed to the corner posts using self-tapping screws with a wide head. If the height of the room is non-standard (as in the second example), then an H-shaped profile for extension is mounted to the sheathing at a distance of 3 meters from the floor.
PVC installation begins from any angle. The first panel is installed, aligned plumb and fixed to the frame. The remaining panels are assembled by analogy. The last corner sheet is cut to a width corresponding to the remaining gap. It is first tucked into the connecting corner and then pushed into the lock of the previous installed panel. The remaining planes are sutured in the same way as described above. If the height is non-standard, the first row is sutured first, then the extension is carried out.
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 premises.
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:
- In the frame of the structure you can hide electrical wiring, ventilation and other communications.
- 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.
- Simple installation and dismantling process.
- Possibility of installing additional insulation from noise, moisture, and sound into the frame.
- Wall panels are strong, durable, plastic, moisture and fire resistant, do not fade in the sun, and are easy to clean.
- When finishing, you can ignore the uneven surface.
Ceilings made of plastic panels also have their negative sides:
- Cheap plastic can allow light from recessed lights to pass through.
- The seams between the panels are visible to the naked eye.
- There is no possibility of making a multi-level structure or bending.
- 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.
- 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.
- External and internal plastic corners are necessary to make beautiful joints at the corners of the room.
- H-profiles connect the ends of several panels.
- A plastic ceiling plinth is needed to hide the ends of the panels. This is the same starting profile, only with decorative trim.
- 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.
