Calculation of the number and area of ​​the lining

The popularity of using such a finishing material as lining is increasing daily. There are good reasons for this:

Molded board is a versatile material that is perfect for cladding external and internal wall surfaces. The price makes the material affordable for most. A rich assortment of materials used in the creation, and also makes it possible to use it in a variety of design-type projects.

But whatever lining you choose, errors in calculating the number of lining can not only disrupt the current repair process, but also significantly change the expected finishing result.

Choosing a variety of wood

At the moment, the construction market is overflowing with many options for finishing, and therefore for a beginner in the construction and repair business, the selection of lining can turn into a serious test. The main thing that a buyer should go with for a purchase is such a concept of the specified value of the required amount of material. This approach helps to prevent certain awkward situations.

Since the purchase of surplus building materials can lead not only to a loss of funds, but also time for its probable return.

Please note that when choosing a wooden lining, special attention should be paid to the type of wood from which it is made.

The most popular options are coniferous and deciduous trees.

It is required to consider the varieties of trees that are often used in the manufacture of lining:

  1. Calculation of the number and area of ​​the lining Pine - differs in high strength indicators, which attracts consumers. But here you need to know the fact that pine lining quickly loses its original color, if it is not treated with stain or protective varnish.
  2. Oak is an incredibly beautiful wood structure that almost does not give in to decay, and also makes the lining the leader in the list of the most popular materials for finishing. Its only drawback is its high cost, which is far from affordable for everyone.

  3. Ash - it is not used very often, since the processing of this tree is quite costly and laborious. But at the same time, the ash tree is durable and does not change its shape and structure when dried.
  4. Lipa is the best option to equip steam rooms in a sauna or steam bath. It perfectly retains heat, and at the same time does not emit harmful resin oils for humans.

Consider what woody varieties are.

Sorts of wood

The quality of lumber, and as a consequence, the final type of product, will significantly affect the cost of the lining.

There are four main types of wood that can affect such an indicator as cost:

  • Category No. 1, "Extra" - this is the highest class of wood, which is its surface does not have knots, cracks and other defects.
  • Category No. 2, "A" is assigned to wood, which can have 1-2 knots for each running meter of the board.

  • Category No. 2, "B" suggests that there are dark-colored defects on the wood surface, up to 1 cm in diameter.
  • Category No. 3, "C" is assigned for low-quality wood from which lining, and the price of such material corresponds to the quality.

It is not difficult to calculate the required amount of material.

If difficulties arise, a construction materials seller can always come to the rescue. It is important that all calculations are carried out on time, before the transaction is made. This helps to save money and prevent a lot of scrap after renovation work. Of course, there should be a supply of lining, but within reasonable limits. As a rule, masters advise adding from 10 to 15% to the calculated value.

Please note that when choosing a lining, it is important to take into account the functional purpose of the room where the finishing work will take place.

What units are used to implement the lining

Calculation of the area of ​​the lining is extremely important. Basically, it is sold in cubic meters, which helps to create certain inconveniences when calculating the required amount of material. For greater convenience, you should remember what approximately the area can be covered by a lining of one size or another:

  • Panel, the dimensions of which are 600 * 20 * 0. 8 cm, covers an area of ​​1.

    2 square meters.

  • If the properties of the lining are 600 * 25 * 0. 5 cm, then the area will be 1.5 square meters.
  • Panel with size 260 * 14.

    8 * 0. 6 meters, will cover an area of ​​7.07 square meters.

As you can see, the dimensions of the material will take into account the thickness indicator. If the lining is sold by the piece, then the thickness indicator will not matter, and is also not used in calculations.

But when selling material in certain units of volume, the thickness parameter will have a tangible effect on the final result when calculating the required number of lining.

How to calculate the number of lining

Calculation of the number of lining is performed according to the algorithm presented below.

First, determine the total area for finishing:

Calculation of the number and area of ​​the lining S = (2АН + 2ВН ) - ( ahn + bh1 n1), where A is the length of the room, H is the height of the room, B is the width, a is the window width, b is the width of the doors, h and h 1 is the height of the window as well as the door, and n and n 1 is the number of windows and doors. If we take into account the ceiling area, then the calculation formula looks like this:

S = (2AH + 2BH + AB) - (ahn + bh1n1)

It is required to determine the area of ​​the lining for the attic, and its ceiling is represented by two surfaces and a vertical type front without bulkheads:

S = 2 AB + 2 b (4 A2- b2) / 4, wherein A is the distance from the ridge to the pitched base.If you need to calculate the number of material for an attic with bulkheads, then the formula will look different:

S = 2AB + 2b (4A2-b2) / 4 + Ph, and P is the bulkhead perimeter and h is the wall height.

You can calculate the total area of ​​the panel using simple calculations. In order to determine the area of ​​the panel, you need to multiply the length of the panel by the width. In the result obtained, it is required to subtract the area of ​​the groove, which is not the elements of the skin surface. To calculate the required amount of material per piece, it is required to divide the total area of ​​the cladding into a single panel.

Calculations can be carried out manually, but this process, as a rule, takes a lot of time and effort.

Special programs for a PC or an online calculator for calculating lining help to speed it up and make it easier. As practice has shown, the final values ​​when using this method will not significantly stand out from those that would come out with manual calculation.


Calculation of the required number of lining for finishing all surfaces of your country house is easy to perform. You can calculate everything you need, manually, or use the computer programs of the online calculator. To do this, you only need to know the exact values ​​of the main surface parameters, namely the height, width, length, and also the thickness of a material such as lining.

Calculation reliability not only saves the repair budget from unnecessary costs, but also eliminates a lot of scrap. But still, when calculating the value of the required number of lining, it should be remembered that the fractional value must always be rounded up and added to the resulting number up to 15% of the material stock. After the calculation of the required number of lining has been carried out, installation can begin.
