WPC facade board - step-by-step installation instructions

Wood and plastic are well-known and widespread materials, each with its own pros and cons. Until recently, the disadvantages of using plastic and wood were minimized with the help of special additives and impregnations, but modern technologies allow the creation of completely new, revolutionary materials. One of them is called wood-polymer composite (WPC), or simply liquid wood.

What is wood-polymer composite?

In essence, wood-polymer composite is something between wood and plastic. It is made from shredded wood with the addition of polymers (polypropylene, polyvinyl chloride, etc.

) - the particles of the materials are mixed, after which, under the influence of high temperature and pressure, the mass is given an appropriate shape. Moreover, the wood content in the material can be up to 90%. In such a combination, WPC acquires the positive properties of wood and plastic, and its use gives a number of advantages.

WPC - composition

  1. Resistance to negative factors . Since the basis of the material is plastic, the material is not subject to rotting, corrosion and damage by pests.

    In addition, fungal spores and pathogenic microorganisms do not multiply in them.

    Does not rot and does not crack

  3. Durability and strength . WPC well tolerates mechanical damage, stress, as well as exposure to chemical and aggressive substances.

    In addition, the material is highly frost-resistant, so it can be used in regions with a difficult climate.

    Does not fade in the sun

  4. Fire safety. With the correct installation of the facade and the implementation of all the necessary measures (processing of wooden elements that are used for the installation of the frame, the appropriate compositions), the material almost completely eliminates the risk of accidental fire.
  5. Excellent heat-saving and noise-insulating characteristics . Installation of WPC board facade systems in residential buildings increases noise insulation by 50% and retains heat 30% better than other facing materials.

  6. Attractive appearance. The wood-polymer composite has a unique structure characteristic of wood, and the boards are very easy to join, so the seams at the joints are almost invisible. WPC surfaces combine well with any materials, fit into any architectural style and do not require additional processing.

  7. High environmental friendliness. Quality materials are made using non-toxic polymers, and the proportion of wood in them is at least 60%.

    WPC facade board - step-by-step installation instructions

    High environmental friendliness

  8. Ease of processing. WPC laying does not require special tools or skills: it can be cut and fastened with ordinary hardware.

Like any other material, wood-polymer composite has a number of disadvantages that should be considered when purchasing and installing it.

  1. High thermal expansion coefficient. In this regard, when installing the WPC, it is necessary to pay special attention to the deformation gaps.

    According to technical standards, for operation at temperatures from -30 to +40 degrees, the material requires an expansion joint with a width of about 5 mm per linear meter. Styling is carried out exclusively on special clips, which are sold separately.

  2. Low resistance to abrasion and fading. The surface of the WPC does not have a protective coating, so its surface is easily susceptible to mechanical damage. For the same reason, it can change color, especially if placed on the sunny side.

How to choose a WPC facade board?

Wood flour is used to make a WPC facade board, the quality of which does not really matter, but special attention should be paid to the binding components. A material based on polyethylene and its derivatives is quite cheap and contains a large amount of wood, but at the same time it is highly susceptible to fading in the sun. Another type of material, which is made using PVC, is more resistant to temperature extremes, ultraviolet light and fire, and is also twice as durable as analogues.

Step-by-step instructions for installing a WPC facade board

Correct installation of wood-polymer composite is a guarantee of durability, reliability and attractive appearance of the finish. The facade made of WPC panels and boards belongs to the so-called ventilated facades, which have a number of advantages over other structures.

Despite the fact that the installation process in this case is quite simple, it requires compliance with some important rules.

  1. WPC board is not recommended for cladding buildings made of hollow materials (for example, aerated concrete), since it requires the installation of a massive frame that can damage the walls.
  2. Store the material should be stored in a dry place in a horizontal position so that the board does not bend. If it is stored outdoors, cover the boards with an opaque material.
  3. Do not pay attention to the fact that there may be slight differences in shades between individual elements.

    This can happen due to the use of different raw materials and WPC processing technologies, but at the same time it guarantees that the finished surface will have a natural look.

  4. Before starting the installation, it is advisable to place the material for 72 hours so that it has time to acclimatize. Work can be carried out at temperatures from -10 to +35 degrees.
  5. It is very important to use only high quality hardware, preferably galvanized or stainless steel.
  6. Before installing WPC panels, it is necessary to install a rigid frame made of composite logs, galvanized or aluminum profiles on the building.

    It is not recommended to use wood for these purposes, as it is too strongly susceptible to weathering and can lead to deformation of heavier WPC panels. If the need to install a wooden lattice still arises, you need to choose durable wood, processed at the factory (for example, bog oak).

  7. The wood-polymer composite is not suitable for use in closed places and in places with high humidity (for example, in baths).
  8. Wood-plastic composite panels should not be clad directly from the ground, but only from the base of the building.
  9. It is better to buy additional elements for decorating a finished facade from the material manufacturer.

    If this is not possible, their technological and design features should be taken into account, otherwise they can spoil the appearance of the facade or even make it less reliable and durable.

  10. Before installation, it is imperative to check the material for damage and cracks.

Important: experts recommend assembling the wood-polymer composite at least two people, as this will greatly simplify the work.

Another important point is that during installation, the distance required for thermal expansion of the material must be maintained, which depends on environmental conditions.

Installation of panels from DPK is carried out in several stages, each of which is very important for the final result.

Stage one.

Preparation of tools and materials

In addition to wood-polymer composite panels (the calculation must be carried out taking into account the area of ​​the facade plus 10-15%), the following materials will be needed for cladding:

  • mounting clips;

    Clip for front panel

  • special hangers (brackets);
  • profile (usually , which is used for drywall);
  • hardware (dowel-nails, anchors, self-tapping screws);
  • additional elements: corners, guide rails, platbands, etc.

In addition, a number of tools must be prepared to perform the work, including:

  • electric drill;
  • hammer drill;
  • screwdriver;
  • hand-held circular saw;
  • hammer;
  • level (length not less than 60 cm);
  • scissors for metal;
  • carpentry metal square;
  • ruler, tape measure, pencil.

Stage two. Surface preparation

Before mounting the WPC panels on walls, they must be properly prepared.

Any unreliable or worn surface features should be removed, replaced or deburred. If there are residues of old coating (eg plaster) on the walls, they must be removed and, if possible, drain pipes, fixtures for lamps and protruding window sills should be removed.

Example installation of WPC siding

The frame is a very important part of the hinged ventilated facade, on which the durability and reliability of the entire finish depends. First of all, you need to make a project and develop wiring diagrams so that the crate is installed appropriately, after which you can proceed directly to the work.

Installation of the frame can be done in three ways: with the help of aluminum profiles (well-processed and dried wooden beams), wood-polymer profiles or L-shaped brackets and profiles.

Option # 1 . Aluminum profiles (wood).

The advantages of such a frame are ease of installation and low cost. For the lathing, it is not recommended to take an untreated or wet timber, since there is a possibility of skewing the entire structure.

Option No. 3. L-shaped brackets or profiles. A universal design that makes it possible to use insulation of any thickness, and the L-shaped profiles compensate for all differences and distortions of the surface.

In this case, the facing material is attached to the frame with clamps.

The sequence of actions when installing a frame from a profile for a ventilated facade is as follows.

Step 1. Determine the height of the facade installation along the wall perimeter, as well as the vertical and horizontal levels.

Important: a wider profile must be installed at the joints of the panels (you can use two intermediate elements installed side by side).

Step 2. Use a pencil and a level to mark the walls vertically - it will serve as a guide for mounting brackets, and the interval between marks should be 30-50 cm.

Step 3. Attach the brackets in one vertical line starting from the corner of the building. Installation is carried out as follows: holes are drilled on the surface at intervals of 40-60 cm, then the brackets are fixed with the help of anchors or dowel-nails.

Wall cladding components

The extreme rows of elements are installed at a distance of no more than 20 cm from the corners and slopes. At the top and bottom of the facade, the brackets should be mounted horizontally, the distance is 10-15 mm from the wall.

Step 4. Attach the first profile to the brackets (start again from the corner of the building), then screw the second profile on the other corner, aligning them along one line. Next, attach the brackets along the entire wall, with the exception of window openings, and screw the profile to them, constantly checking the evenness of the frame.

It is recommended to fasten the profile with two self-tapping screws to each bracket, screwing them into the pre-drilled holes.

Step 5. In the same way, assemble the frame for the remaining walls, after which in the right places, install the end, corner and docking strips so that the structure is a whole.

The wooden lathing is mounted in the same way, only instead of brackets, ordinary logs are used, which are attached to the wall with screws.

Stage four.

Installation of insulation

Installation of insulation is carried out if it is planned by the project. Insulation allows you to get rid of the so-called cold bridges, which are formed between the frame and the wall. The choice of method depends on what type of material has been chosen, since each of them has its own styling characteristics.

Important: under any insulation and on it, a special membrane must be placed with a vapor barrier effect. As a result, it should be as if packed in a membrane bag - without this, the material can get wet and completely lose its properties.

  1. Basalt or mineral wool is attached to the surface using plastic dowels with a wide head. First, you need to drill holes in the surface to a depth of 5-6 cm, then insert a dowel there and fix it with a spacer nail. About 6 dowels are taken per square meter of material.
  2. Glue is used for foam and polystyrene foam, and the material must be laid in at least two rows, and the joints must be foamed. This is the best option for residential buildings, providing complete thermal insulation.

Applying cement-polymer glue to the foam board

The thickness of the insulation should be equal to the thickness of the frame elements so that the finished cladding does not deformed and did not bend. Important: it is not recommended to use cheap and low-quality material to insulate a ventilated facade made of WPC, since they have a tendency to cake, which is why they cease to perform their functions, and fungi and mold can begin to multiply under the facade.

Wall cladding

To fix the WPC board to the frame, special clips and self-tapping screws and screws are used (the recommended length is 20-25 mm, width - 2.5-3 mm), as well as clamps.

Installation should start from the bottom corner of the building and continue horizontally, laying the boards in rows, and it is important that there are ventilation joints between the wall in the upper and lower part of it and the mounted facade for ventilation.

Step 1. Drill a hole at the very bottom of the frame, and its diameter should be slightly larger than the diameter of the self-tapping screw.

Step 2. Insert the front board, fix it with a clip and a self-tapping screw, screwing it as perpendicular to the surface as possible so as not to damage the material.

When tightening the screws, you do not need to apply too much force, as this can cause deformation or cracking of the board. It should not "sit" too tightly, otherwise the facade may crack during thermal expansion and contraction of the material.

Typical nodes

Note: if clamps are used to fasten the board, make sure that they are tight, but without effort entered the longitudinal grooves.

Step 3. Insert the fixing clip into the top of the first row of planks and install the next plank, securing it as described above.

It is recommended to fasten each panel to the profile with two self-tapping screws, and special attention should be paid to the joints of the profile and the board (in these places the fastening must be especially strong). It is better to install the subsequent upper rows of panels with a slight displacement of the seams.

WPC siding

WPC board facade wood-polymer composite does not require any special care - the surface can be washed with a hose, and cleaned with simple household products.

It is better to remove stubborn dirt immediately, and for this it is allowed to use a pressure washer (maximum 80 bar, minimum distance from the surface 20 cm) Grease and oil stains are removed using household chemicals suitable for wood and ceramic surfaces using a medium-hard brush. After the procedure, be sure to rinse the facade with water.

It should be noted that the most difficult material to maintain is a façade board of light colors, since it has a relief surface in which dirt and dust can accumulate. If minor scratches appear on the boards during cleaning, they can be removed by sanding.

To prevent the appearance of mold and mildew, you need to thoroughly wash the WPC facade during the flowering period, when pollen can fly in the air, and also strictly follow the instructions for laying the material.
