# Sheathing and finishing of the pediment of a wooden house

## Recommendation points

The choice of gable finishing depends on the purpose of the attic space, the architectural design of the facade and the structure of the outer wall of the building. In this material, we will consider the most affordable for self-execution methods of finishing the pediment.

## Consumption of materials for various forms of gable

The front in architecture is called the upper part of the facade of the building, bounded from below by a cornice or attic floor, and from above by the edges of the roof slopes. The shape of the pediment directly depends on the construction of the roof of the house. Hip and hip roofs cover the facade of the attic space with a slope. Other types can have both a simple and a complex geometric shape of the pediment, but in the overwhelming majority in the vertical plane.

It is best to make a preliminary drawing of all surfaces to be finished to scale. On it, mark the detailed layout of the elements (panels, sheets, boards, etc.) of the finish. In this case, it will be possible to calculate all the dimensions of the additional parts. To the final amount received, even with the most careful calculation, it is necessary to add 10% of the total amount for unforeseen expenses.

If the decoration is made from small parts, then the calculation is made based on the area of ​​the surface to be trimmed, which is divided by the area of ​​one element. So, for example, for a pitched roof there will be three gable areas: front – a rectangle (S1); two side right triangles (S2, S3).

• total finishing area S = S1 + S2 + S3;
• area of ​​one finishing detail – Sd;
• all finishing details will be required – n = S / Sд.

More complex geometric forms of the pediment can be divided into simple ones (triangle, rectangle, trapezoid). The total area will be their sum. Further, the number of necessary parts is calculated according to the principle described above. You also need to add 10% to the result..

## Features of the device of the insulated attic pediment

When the attic space is used as a living space, the gable sheathing is done simultaneously with the insulation. The gable frame and / or lathing is mounted with a tie to the roof truss system. The vertical or horizontal structure of the battens depends on the installation method of the cladding. The design of the battens, counter battens and the sequence of insulation layers depends on the material selected as insulation. It is best to continue the insulation in the same way as the internal roof insulation..

1. Laga. 2. Inner layer of vapor barrier. 3. Insulation. 4. Sheathing. 5. Wind protection. 6. Sheathing (block house)

The thickness of the batten must correspond to the thickness of the insulation. This leaves a gap of 3 cm on the outside of the facade for ventilation of the wooden elements of the gable structure. Insulation of the required thickness is installed between the lathing bars, which depends on the climatic region of construction.

The most commonly used mineral wool board. It is better to choose a basalt semi-rigid slab for stability (density 80, 100 kg / m3). On the inside, the mineral wool is protected by a vapor barrier membrane, on the outside, a moisture and windproof membrane is laid.

The next stage in the construction of the gable wall will be internal and external decoration. All wooden parts must be treated with antiseptics. The width of the slab is taken slightly larger than the distance between the details of the crate for better stability of the insulation due to the expansion.

## Sheathing the pediment with clapboard

The type of finishing is chosen to be similar or at least combined with the general appearance of the building facade. The most common decoration of wooden houses is clapboard paneling of the pediment. Its advantages are simplicity of installation, unpretentious operation, attractive appearance. Durability is ensured by processing with special compounds against the negative influence of the external environment.

According to the quality requirements for the lining (euro lining), it is subdivided into classes “A”, “B”, “C”. For facing the pediment, it is better to choose class “A” lining.

## Finishing the pediment with a block house

Block house is also a fairly common finishing material for wooden buildings. It imitates the shape of a log. Finishing the pediment with it will be an excellent continuation of the facade of a log house. This does not add additional load to the foundation..

The speed and simplicity of installation of this material with high quality finishes allow you to make a choice in favor of a block house with many options for the exterior of the house.

## Gable trim with planken

Finishing the pediment with a front board, which is also called planken, will last longer than the lining, as it is made of hard wood. It is actually a profiled board, which is given various shapes..

Its installation differs from other types of finishing with wooden parts in that a gap is left between the boards here. This allows you not to create stress during deformation of the wood, provides additional ventilation to the wooden parts, and also makes it easier to replace the damaged board.

## Timber imitation finish

Another type of finishing the pediment of a wooden house is with the help of a planed board for a timber. Most often it is just a continuation of the exterior of the facade. For houses from a bar, in order to preserve the integrity of the architectural solution, such cladding solves the problem of reducing the load on the foundation..

## Siding gable trim

The siding pediment reliably protects the wall structure and is undoubtedly an adornment of any facade. Wooden siding is used less and less, its artificial analogue – vinyl siding, which has the advantage of imitating any natural material, a variety of textures and colors, is replacing it. It is durable, moisture and heat resistant, does not fade and does not rot.

Metal siding is more expensive and rarely used for residential construction. The popularity of outdoor siding is explained, among other things, by the presence of a large number of additional elements. This greatly simplifies the installation of the cladding and increases the decorative effect of the finish..

## Sheathing of the gable with profiled sheet

The profiled sheet is made of galvanized sheet steel. Its wavy shape is due to the creation of stiffening ribs. A decorative polymer coating on the outer side of the sheet protects it from corrosion and gives the finish a beautiful appearance with a pronounced texture. It is a strong, lightweight, durable, moisture and bio-resistant finishing material. Among the disadvantages: the material heats up strongly in the sun, the complete lack of sound insulating properties.

## The sequence of works on finishing the pediment

Regardless of the choice of the gable finish, the crate is attached to the rafter roof structure. It can be a beam of 60×40 or 50×50 mm. Based on the vertical or horizontal installation options for finishing elements, the battens are installed in the opposite direction.

All wooden parts of the pediment must be dried to a maximum moisture content of 20% and impregnated with an antiseptic. The pitch of the bars is no more than 40 mm. In each case, it is specified in accordance with the dimensions of the facing material. For the lathing, you can also use ready-made parts of the metal frame, but a cheaper option is a wooden one.

If the pediment is finished on the old surface, then it is thoroughly cleaned of dirt. All details (platbands, window sills, decorative elements) must be removed. Defective gable surface parts need to be replaced or repaired.

The installation of the lathing is carried out taking into account the framing of the upper part of the pediment and window openings, if any. Fasteners (nails, screws, self-tapping screws) must be resistant to corrosion and ensure the strength of the connection of one part with another with the required clamping depth of fasteners (25-30 mm).

In the case when the finishing is made with panels with the selection of ready-made additional elements, the installation begins with their installation. Only then the main cladding sheet is erected. This also applies to low tide, for example, in siding. The planking is installed horizontally from bottom to top, vertical – from the middle to the edges.

A beautifully and high-quality finished pediment can change the face of the house beyond recognition and create a new style of the building’s exterior.
