Did you know plastic siding expands when its warm and shrinks when its cold? We call this working, the working can take place deformation and / or discoloration. However, this problem can not arise, when it meets the proper installation requirements.

When installing siding must be taken into account with the possibility of expansion of the panels due to temperature differences. If there is no attention of this expansion, the wall panels can work more than usual. Extreme force may crack the top layer causing discoloration may occur. This is more common in dark colors panels because they hold more heat. We would like to remodel your point to the correct assembly instructions regarding proper ventilation, discoloration or avoid tapping.

Proper installation of siding

The correct mounting of cladding with the line of work in which the panels are attached to. The battens must have a minimum aperture and maximum spacing. The distances vary according to the brand, the correct instruction you we like to refer to the specific installation instructions under the tab downloads.

In addition to the proper distances from the lath and the cladding, it is of great importance that are used in the mounting of cladding, the ventilation profile (art.nr.423) and the ventilation sealing profile (art.nr.424). Ventilating structures ensure that there is no wildlife behind the siding and air can always be ventilated at the top. Does the air not move, then the heat will accumulate. As the air accumulates there can be permanent deformation or discoloration occur.

Siding confirm loosely

By the expansion and the shrinking starts to move the panel. When mounting of facade elements must, therefore, each screw to be tightened loosely so the panel will have the possibility to be able to move freely. If the panel is tightened up too much, tension is built up at the point of attachment, with can result to shoot the panels off. This will gives the ticking noise as a result. If the panel does not slip, the tension remains allowing the panel to remain structurally deformed.
