Over 4.5 billion Square feet of DERBIGUM defy every sort of climate
all over the World. For more than 25 years, the DERBIGUM membrane
has proved its reliability from the far North to the Tropics.
APP (Atactic Polypropylene) Modified Bitumen material is blended
with the highest quality raw materials to provide a membrane with
superior flexibility, strength, and stability, even at sub zero
A special blend of asphalt and polymers allows the membrane to be
torched, heat welded, or applied with premium Permastic Adhesives.
A tough glass fiber mat provides superior membrane tensile
strength (up to 200 lbs/inch) with resistance to punctures and wear.
DERBIGUM and DERBICOLOR products may only be install by roofing
contractors that are approved by Performance Roof Systems through an
ongoing process of training and inspections.
EMPIRE ROOFING is a Performance Approved Contractor.
