ROOF UNDERLAYMENT


Grace Construction Products Grace Ice & Water Shield HT is made with innovative and propri-


etary rubberized asphalt that will not flow, even at temperatures as high as 240 F. It provides 120 days of exposure time to provide peace of mind during long, unpredictable construction cycles and, because the membrane bonds firmly to the deck, there is no need for heat or special adhesives. www.graceconstruction.com | Circle #65


Te Garland Co. Inc. The Garland Co.’s HPR Aqua Shield self-adhering underlayment is a light-


weight, reinforced base sheet designed for a variety of steep- and low-slope roofing applications. Formulated using a high-quality Styrene-Butadiene- Rubber modified bitumen; the underlayment is reinforced with high-strength fiberglass. Its self-adhering technology uses an advanced adhesive surface. www.garlandco.com | Circle #66


Englert Inc. Englert’s HT Underlayment features black, non-woven polyester topside designed for use as a metal underlay-


ment. The new self-adhering, slip-resistant product is 100 percent UV protected, heat reflective and slip resis- tant, and good for 90 days of exposure to accommodate construction scheduling and weather delays. Englert HT Underlayment provides an excellent defense against costly ice dams and wind driven rains, sleet and snow, particularly in the cold winter months. The new Englert membrane is designed for use in high-temperature environments where the in-service tem-


perature can reach as high as 250 F. The self-sealing, high-tensile strength underlayment comes in two configura- tions, each designed to provide waterproof protection before, during and after the installation of metal roofing. www.englertinc.com | Circle #67


Firestone Building Products New to the line of Firestone CLAD-GARD metal roofing underlayments is CLAD-


GARD R, an economical choice in Firestone’s self-adhered underlayment offering with a distinctively textured, skid-resistant surface for greater walkability during installation and maintenance. Available in an unboxed, two-square roll, this underlayment has a split-release backer for easy installation and can be directly applied to Firestone HailGard Composite, OSB and plywood substrates.
