Challenges in building protection

When protecting roof cladding and PV system substructures, problems often arise that are exacerbated by the choice of unsuitable protective materials:

Materials such as aluminum are subject to temperature-induced contractions and expansions of up to 1 mm per meter length, which can endanger the stability of PV systems in the long term. In addition, vibrations caused by machines or wind lead to mechanical movements in the substructure, which increases the material load and can cause damage. Commonly used building protection materials such as fleece materials, EPDM mats and rubber granules have various weaknesses, including a lack of weather resistance, compaction over time and susceptibility to bird damage.

PMT Pro-& Easy Plate: The solution for long-term protection

With the Pro-&EasyPlate, PMT offers an innovative solution that has been specially developed to meet the requirements of PV systems. The plate is made of high-density polyethylene (PEHD), a material with outstanding physical properties:

High abrasion resistance: Due to a high Shore hardness (= scratch hardness); the higher the scratch hardness, the lower the abrasion.
Adapted material structure: The innovative design of the plate minimizes the contact surface with the roof cladding and thus reduces friction effects.

In addition, extensive tests simulate over 25 years of use. The plate is tested under realistic conditions - a unique procedure on the market.

Conclusion: safety and quality combined

With the Pro-&Easy Plate, PMT offers a solution that is characterized by reliability and innovation. All tests, including adhesion and abrasion tests, have been successfully passed on a wide variety of roofing membranes. This confirms PEHD as the ideal material for building protection.
