Grace Ice & Water Shield HT (High Temperature)

Grace Ice & Water Shield® HT is an excellent high temperature ice and water barrier that follows in the footsteps of the original Ice and Water Shield®, but is specially formulated to meet the higher service temperatures that often encountered in metal roofing systems. The product is formulated with a proprietary adhesive with temperature resistance of up to 260°F. The membrane forms a watertight bond to the roof deck, and seals around fasteners to around the nail of the primary roof covering and thus maintains its waterproof integrity on the roof deck.
