Grace Ice and Water Shield HT fully-adhered, smooth surface roofing underlayment is specifically designed for high temperature applications such as metal and tile roofs. It delivers all the advantages of Grace Ice and Water Shield roofing underlayment with thermal stability metal and tile roofs require. Not all high temperature roofing underlayments are the same. Grace Ice and 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 are inherent to metal and tile roofs. The proprietary adhesive if formulated with a temperature resistance of up to 260°F. The peel and stick membrane forms a watertight bond to the roof deck, and seals around the primary roof covering fasteners to protect the roof deck from water intrusion. It also creates a strong bond to the roof deck. Grace Ice and Water Shield HT peel and stick roofing underlayment delivers an optimal balance of adhesion and thermal stability for superior performance under the most demanding roof types, such as metal and tile roofs.
