Key Installation Considerations for APP Modified Bitumen Membrane
APP membranes are torch-applied, so installation quality directly affects performance. Substrate must be flat and dry, with primer for adhesion. Install from low to high with proper lap width. Heat evenly to melt the modified bitumen without burning, then roll to remove air. Details like corners and pipe penetrations need additional reinforcement. Water testing should follow installation to verify performance. Protect finished work from damage by subsequent trades. Only with proper installation can APP membranes deliver their full performance advantages.
