Not all high temperature roofing underlayments are the same. Grace Ice & Water Shield® HT is an excellent high temperature ice and water barrier that follows in the footsteps of the original Grace 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. It also creates a strong bond to the roof deck and delivers optimal balance of adhesion & thermal stability for superior performance under the most demanding conditions.
Waterproofing ability is critical when choosing an underlayment, but another factor to consider is its exposure time. Grace Ice & Water Shield® HT has been formulated and tested to be UV stable for up to 120 days, ensuring the building stays safe and dry during long and unpredictable construction cycles. It delivers the schedule flexibility you need and the waterproofing performance you trust.
Protect metal roofs from wind driven rains and ice dams, and have peace of mind against costly call-backs with Grace Ice & Water Shield® HT – the best in class high temperature ice and water barrier.
