How to calculate home siding: basic methods + step by step instructions!

The beautiful facade of the house, and in general a pleasant-looking cladding, is an indicator that the owner of the building is a caring and attentive owner who loves beauty, comfort and who knows a lot about style. That is why (and also for a practical purpose) often wooden (and not only wooden) buildings are sheathed with siding. These narrow panels make the home look modern and stylish. However, siding is not just one solid "wall", it is a huge number of panels fixed to the wall of the building. And how to calculate siding for a house so as not to spend extra money on the purchase of material is another science with which we will try to figure it out today.

What is siding and why should it be considered?

Siding is a transliterated name for a special type of cladding of wall surfaces of various buildings. It is a fairly narrow panel that is fixed to the surface at a certain angle using special devices.

What is siding and its advantages

Siding has two functions:

  • aesthetic , that is, it makes the walls of the house neat and beautiful;
  • protective , that is, it protects the walls from environmental factors (snow, wind, rain, etc.).

Note! For the first time siding appeared and began to be used in the 19th century. The people of North America processed the boards, giving them a neat appearance, and fixed them on the walls in such a way that each layer overhang somewhat over the previous one; this made it possible to achieve that the water easily rolled down the walls during the rain and did not linger on them.

Types of siding

If earlier siding was made exclusively from planed and painted boards, now there are several types of this facing material.

Wooden

As you might guess, this type of finishing material is made of wood. In turn, it differs in the way the wood is processed and the type of section of the finished panel. By the type of wood processing, they distinguish between impregnated wood (impregnated with antiseptics), heat-treated (processed in conditions of high humidity and at a temperature of + 170-220 degrees, due to which it becomes strong and better resists negative factors), as well as dried wood (the material is dried to a moisture level 16-18%). Also, wooden siding is subdivided according to the type of sections. There are overlap siding, end-to-end, quarter, groove-comb.

Woody

This is different the type is called glued clapboard.Such siding is made of wood fiber, which is pressed under the influence of high temperatures and with the addition of resins, and is covered with varnish or paint on top, which allows protecting the material from environmental factors. Siding looks like natural wood, it is often used for cladding rooms from the inside. It does not burn and has a service life of at least 15 years.

Metallic

This type of siding is rare It is used for cladding residential buildings, but ideal for decorating industrial buildings and warehouses.

The panels are made of aluminum, coated with a protective compound that reduces the risk of corrosion. Thus, metal siding is reliably protected from external environmental influences. The main drawback of the material is its considerable weight.

Cement

Cement and cellulose fiber - that's what this type of siding is made of. Such panels are not afraid of fire, and therefore increase the fire safety indicators of the building.

Such siding is expensive, and it has a lot of weight. Houses are rarely faced with them.

Vinyl

Universal type of siding, if you can call it that, because it can be used for cladding any type of building. It looks like an ordinary board, but at the same time it lasts much longer than ordinary wood siding - the average service life of this material exceeds 20 years. It is not afraid of wind, frost, rain, has a wide range of colors, is easy to clean and requires virtually no maintenance.


Vinyl siding is most often used to decorate the facade of the house, which is not surprising - these finishing panels have a lot of advantages:

  • the material is not afraid of the effects of external natural factors;
  • it is not afraid of moderate force of mechanical influences, it hardly scratches, does not crack;
  • does not suffer from rotting and corrosion;
  • insects-pests do not settle on it;
  • it is not toxic, environmentally friendly for humans;
  • does not conduct electricity;
  • panels of such siding have holes, so the walls are capable of " breathe ", condensation does not accumulate under them;
  • siding is easy to install;
  • easy to clean, easy to clean and wash;
  • durable - the maximum service life is 50 years old.

Note! Vinyl siding began to conquer the building materials market around the 50s of the twentieth century in America and Canada. And immediately gained popularity.

What to Count?

Siding is one of the easiest ways to improve the look of your home. However, in order for the siding to be wall-mounted, it must first be purchased.

But no one wants to spend extra money on material that can remain lying around in the barn, or vice versa - to buy too few siding panels.Therefore, it is so important to calculate the required number of panels before going to the store.

To clad walls with siding, it is not enough to buy only the material itself. Other elements are also needed, which will be discussed in the table below.

Accessories for facing the house with siding

Table.

Siding accessories for house cladding.

Profile type Description
Wall panel The same ordinary siding that will create a beautiful appearance of the building. It can be of various sizes and colors. Usually mounted horizontally.
Starting profile It is attached to the lower level of the facing and will serve as a guide for the first row of siding.

It is connected to the first line with a special lock connector.

Starting bar Performs the same functions as the starting profile, but in the rear shelf it is lower than the profile, and less durable ...
Connector bar (H-profile) With it, two pieces of siding are joined into a single system to increase the length of the panel.

Placed vertically and can be used as a separator.

Finishing profile Installed on the last row of facing panels.
Drain bar Located above the projections on the wall, above the protruding part of the base. Plays the role of an ebb or performs a decorative function.
Profile for decorating internal corners Designed to hide the joints of panels between two walls in the internal corners of the building.

It is not always used, as it can be replaced by a J-profile.

Profile for decorating outer corners Designed to hide the joints of panels between two walls at the outer corners of the building. Often used in a different color than the cladding of the house itself (for contrast).
J-profile wide Installed at the joint and is often just a decorative element. Can be transformed into window frames.


Wind board With the help of it, the end part of the cornices is finished. Also helps to fix the soffit.
Slope or near-window profile Used for framing window openings, doors recessed into the wall of the house, for the formation of slopes.
J-profile Used for framing cladding, fixing spotlights, finishing interior corners. In general, a universal profile.


Sofit Profile, outwardly very similar to the siding itself. Sewn onto the bottom of the eaves.

Siding cornice cladding

These are the details and must be purchased in order to successfully mount the cladding of the house. Siding panels alone are indispensable. However, some elements may not be needed - it all depends on the architectural features of the building.

Methods of making calculations

There are three main methods of calculating the amount of materials for wall cladding with siding:

  • graphic;
  • math;
  • using online calculators.

Online Calculators are the easiest way to calculate the number of cladding panels for a house. There are a lot of sites on the Internet offering to use this method of counting. In order to use them, it is enough to know the basic parameters of the house in need of facing, and indicate them in the form offered on the website. The parameters of the walls are entered there, that is, their height and width, the dimensions of windows and doors, the number of external and internal corners, the length of the cornices.

As a result, you can get a number that will be equal to the amount of materials required for cladding the facade of the house. The main drawback of such calculators is that they are not always accurate.

How to calculate home siding: basic methods + step by step instructions!

An example of calculating siding using a special program

When using the mathematical model of counting , a special formula is used that and allows you to calculate the required number of siding panels, where it will be equal to the ratio of the surface area of ​​the walls of the house to the area of ​​the siding panel. In this case, it is important to make a small margin - equal to 7% - and therefore the result obtained during the previous calculations is additionally multiplied by 1.07.

How to calculate home siding: basic methods + step by step instructions!

Calculation of the area of ​​ordinary siding

There is also a graphical way of counting . It is the longest in time, but it is considered the most accurate. To bring this method of making calculations to life, it is necessary to draw on paper an accurate model of the house, taking into account the scale and all dimensions of the building. From another piece of paper, cut strips to scale exactly the size of the siding panels. Further, the "walls" of the painted house are simply "filled with" paper strips - "panels".

As a result, the number of the latter is counted - this is the result of the graphical method of counting the number of siding panels.

Tip! You don't have to draw a house on paper and cut paper strips to bring the graphic method to life. You can use any graphics editor.

Graphic method for calculating siding

When making calculations, it is important to take into account one point - the width of a siding panel can be working and useful ..

. The fact is that each panel has a perforated strip, which at the time of installation will be hidden under another strip, and therefore the full width of this facing element cannot be used for calculations. Here it is important to consider only that part of the panel that will be visible to the eye. Therefore, when considering the size of siding panels, it is worth remembering this little caveat.

We count siding

In order to calculate the siding, you should arm yourself with a pencil, a piece of paper, a tape measure and a calculator.

First you need to calculate the number of siding panels.

Step 1. The first step is to take measurements from the building that needs facing. It is necessary to determine the area of ​​the walls in square meters. Each wall of the house, as well as its gables, are measured separately.

First find out the length of each wall of the house at the base.

Common roof forms

In order to calculate the area of ​​a triangular pediment, measure its height and length, calculations are made according to the formula: half of the base of the triangle is multiplied by its height . To calculate the area of ​​a trapezoidal pediment, measure its base and height.

The area of ​​the trapezoid will be equal to the product of the half-sum of its bases and the height.

How to calculate home siding: basic methods + step by step instructions!

We calculate the area of ​​the pediment

To calculate the area of ​​the pediment in the form of an attic, its area is visually divided into simple geometric shapes and the area of ​​each is considered separately. The results of all areas are summarized.

Step 10. Calculate the total sum of the areas of all gables of the house.

Knowing the total area of ​​the walls and gables, these indicators are summed up and the total area of ​​the whole house is obtained. After that, the sum of the plots that do not require finishing is subtracted from the result obtained. These are windows and doors.

Required siding area

Attention! Cutting the panels can generate waste that cannot be used anymore. This is also important to consider when calculating the amount of siding.

Usually the stock is equal to 10% of the total.

Step 11. Measure the cornices and pediment overhangs to calculate the number of spotlights. To begin with, measure the length of each cornice.

We count additions and accessories

When calculating the costs for the purchase of materials, it is very important to take into account the remaining elements necessary for the installation of the cladding. Even if you plan to sheathe only one wall without windows and doors, you will have to purchase at least a starting bar. However, it is especially important to make accurate calculations if the structure has a complex configuration.

  1. So, the total length of the start and finish strips for siding will be equal to the length of the base of the house. The number of planks is calculated by dividing this number by the length of one plank.

  2. The number of panels for the corners of the house - both internal and external - is considered as follows: the data obtained thanks to the measurements made earlier for each of the types of corners are added together - the total length of both types of corners is obtained. Their number is calculated by dividing the total length by the length of one corner (step 5). Note that it is preferable to mount without joints.

    Therefore, it is better to count the number of corner strips for each corner separately.

  3. The J-profile will frame the window and door openings. Its quantity is found out thanks to the previously calculated perimeter of windows and doors (step 8).
  4. If the window openings are recessed into the walls by more than 2 cm, but less than 18 cm, then window profiles are used for their design. They are counted by the piece for each opening.

How to calculate home siding: basic methods + step by step instructions! Herringbone siding

When choosing siding, the shape of the panels is one of the decisive factors, because it depends on this how it will be look like a facade. Recently, consumers have been interested in the "herringbone" profile, which imitates wooden clapboard trim. Herringbone siding has an expressive texture and pleasant pastel colors, which gives the house a very cozy and attractive look.

This is how you can make accurate calculations and find out how much siding is needed to clad the facade of the house.

Of course, you will have to spend time on calculations, but this is better than running back to the store and buying the missing material, or, on the contrary, not knowing what to do with the excess siding.
