Forget about tearing, wrinkling, water absorption or blown off by high wind, GuardMax™  polymer fabric construction is 25 times stronger than felt and is impervious to mold growth. GuardMax™  is your ideal roofing underlayment for asphalt shingles, tile, slate, metal, and a variety of other roofing material.


***Superior none-woven skid resistance surface offers excellent footing & traction, while underside skid resistance coating reduces movement between membrane and roof deck.


GuardMax™  multi-layer laminated reinforced plastic substrate will not buckle or deform under extreme temperature and crack under long term heat exposure that resulted when asphalt oils dry-out.


GuardMax™  roofing underlayment is also lighter in weight compared to felt, it allows for easier lifting and saves on transportation cost.


Each roll of our GuardMax™ roofing underlayment covers a full 10 squares, and gives more coverage per lap as it is wider in width (48") compared to either felt or other brands of synthetic substrate (36"). It allows faster installation on job & save you more money on material!


Our enhanced UV and anti-aging formula allows the product to be uncovered by the primary roofing material on job-site up to 12 months. Note: Extra fastening is required under extended periods of exposure.


All GuardMax™ roofing underlayment are class A rated fire retardant building material.

The definition of thermal insulation is actually a term used to resist conduction of heat transfer with certain R-values. All material emit energy by thermal radiation as a result of their temperature. The amount of energy radiated depends on the surface temperature and its emissivity. Reflective insulation (also call radiant barrier) is a type of thermal insulation that inhibits heat transfer by thermal radiation through its low emissivity or high R-value.


GT Industrial's newly developed SilverMax™ not only complies with all AC207 criteria as a synthetic water barrier material that can be left without the cover of primary roofing material for up to 6 months, it can also act as a reflective agent that prevents heat energy from transferring between two system of different temperatures. SilverMax™ 30 also carries our special skid resistance feature that provides the best traction and footing within the industry.
