How do I install insulation on my flat roof?

• Step 1: Prime the surface if necessary (refer to manufacturer's instructions for roofing/damp proofing).
• Step 2: Begin gluing the insulation panels at the farthest point from the roof access point and work towards the access point, ensuring not to walk on the glued panels.
• Step 3: After applying the adhesive foam to the insulation panel, wait 2-3 minutes and apply the insulation panel to the flat roof within 5 minutes, pressing firmly at the grooves.
• Step 4: Press firmly for at least 2 hours and do not walk on the panels. (If the insulation panels have shifted or been moved during the curing time of the adhesive foam, reapply the adhesive foam to ensure proper adhesion.)

The roofing and any underlying layers can be applied after the adhesive foam has fully cured.
