Installation Considerations & Best Practices
To get the most out of an Acryldach system, installation must account for several key factors:
-
Thermal Expansion: Acrylic expands and contracts with temperature changes — mounting systems must allow for this movement. Screws should be fitted with rubber washers, and fixing points should accommodate some movement. UK News Pulse
-
Proper Fastening: Use specialized fasteners (screws + EPDM or rubber gaskets) and avoid over-tightening, which can crack the panels.
-
Sealing Joints: Use high-quality, UV-resistant silicone or appropriate gaskets to seal the edges, prevent water ingress, and maintain durability. UK News Pulse
-
Surface Preparation (for Coatings): When using liquid Acryldach, the substrate must be clean, dry, and free of debris. Existing roofs (bitumen, metal, or membrane) may need a primer before applying the coating. mp4moviez.co.uk
-
Curing Conditions: For liquid-applied systems, ambient temperature and humidity affect curing. Proper curing ensures adhesion and longevity. mp4moviez.co.uk
-
Maintenance Access: Design the roof so that panels or the surface can be accessed for cleaning or inspection without damage.
