RT40 BUTYL™ is a 40mil self-adhered flashing membrane. RT40™ is an exclusive laminate of reflective aluminum foil facer with butyl compound. As waterproof flashing membrane, it adheres to most surfaces and seals around punctures, forming a protective air, vapour and waterproof barrier. It is specifically designed to be self-adhered to most substrates without using any primer.

NO PRIMER NEEDED
