Mini-Progard is a Self-Adhesive Waterproofing Membrane designed to protect your roof. Its core is made of SBS modified asphalt, carried by a specifically treated poly (non-slip) sheet. Mini Progard may be installed and sealed directly on approved surfaces, by removing the detachable silicone film. This membrane can be installed under roofing shingles or used as air-barrier/vapor-barrier under a thermal insulation.
