Uniform standards of installation of wood-polymer decking does not exist.Different manufacturers offer their stacking technology and ways of organizing terraced decking.But to

erected design as long as possible the performance and aesthetic properties, it is necessary to observe the basic rules of installation.

first, where to start installation work - a training base, as which can act rubble or gravel (thickness 40 cm), concrete, cobblestones, asphalt base tree.

The substrate must be sound, smooth.All sorts of recesses, depressions, bumps are not allowed.They eliminate using special leveling agents based on cement.Business base sloping downward gradient of at least 1.2% (drop height is 1 cm by 1 meter).

Since profiled decking is designed for outdoor use, it is placed on the support.This allows for removal of moisture and natural ventilation of air under the floor.Many manufacturers offer for that special support profile, made of the same material as the decking itself.It measures every manufact

urer defines itself.

Support lags a way to compensate for the existing slope of the ground.They are mounted parallel to each other at a distance of 50 cm (mount boards perpendicular to the joists).The floorboards can also be stacked at any angle with respect to the support profile.If the anticipated load exceeding 350 kg per individual floorboard, the reference profile is set to a smaller step than the above.Lugs attached to the substrate using anchors, screws (depending on the type of base).

to ensure drainage and space for thermal expansion of the material between the ends of the supporting profiles is recommended to leave a gap of 5-10 mm and 15 mm between the reference profile and the wall.And joists need to be installed so as to overlap the board does not exceed 50 mm.This can lead to sagging floor and ultimately to breakage floorboards.In areas with minimal moisture instead of the lag can be used conventional wooden boards.

Today we know two ways of installation: open and hidden.The first method involves the exercise of fixing boards to the joists on the front side (the first and last board).As a self-tapping fasteners are used with corrosion-resistant coating.In the body of the pre-made street decking holes of smaller diameter, which prevents cracking of the material during screwing screws.For concealed wiring board attached to the inner side or by means of the tool joint, or by means of clips.In the first case floorboards are joined together thanks to the "tongue and groove".

When laying terraced decking should be noted that the profiles of wood-plastic composites (floorboards, logs) during the operation under the influence of temperature and moisture are subject to shrinkage or swelling.To prevent deformation of the floor, between the boards themselves, and between the floorboards and all fixed objects (walls of houses, different architectural elements of the facade) make expansion joints ranging in size from 2-3 mm.

to complete a decorative finish flooring is often used side stub.The ends of the street decking snap-shut aluminum plates.Application side plugs is only relevant when the rectangular end sections.
