ISOGARD HD has the highest thermal performance of any 12 mm rigid cover board and is resistant to extreme weather conditions. It has a superior wind uplift performance, lays flat and requires fewer fasteners per board compared to 25 mm insulation boards.
A single 1.22 m x 2.25 m ISOGARD HD cover board weighs only 5 kg, resulting in easy handling and placement.
Quick and easy to install
ISOGARD HD is easy to cut and handle for quick installation around roofing details such as drains or other penetrations, reducing installation time and labor costs.
High compressive strength
ISOGARD HD has a compressive strength of over 800 kPa (5 to 6 times that of a normal PIR insulation board).
An added measure of protection
ISOGARD HD adds structural strength to the entire roofing system and helps to absorb the effects of hail, foot traffic and other potentially damaging impacts. It can also enhance the fire performance of the roofing system
When installed correctly, ISOGARD HD will last for the lifetime of the building.
ISOGARD HD is composed of mold-resistant material that does not support the growth of damage-causing fungi and bacteria. The board is manufactured with a 100% fiberglass, mold and moisture resistant facer and it contains more than 9% of post-consumer and post-industrial recycled combined content. The foam technology uses a HCFC-free blowing agent with a low GWP (Global Warming Potential) and zero ODP (Ozone Depletion Potential).
