Ice, water and wind protective underlayment
EcoStar Glacier GuardTM 100 underlayment is a 55-mil self-adhering sheet membrane. It protects roof substrates against water penetration from wind-driven rain and from water backup caused by ice dams. This membrane is required in new construction and re-roofing projects beneath all EcoStarยฎ roofing systems and most steep-sloped roofing products. The membrane will self-adhere to clean wood, plywood and metal.
Glacier Guard 100 is a flexible, rubberized asphalt, fiberglass-reinforced membrane with a granular surface that provides maximum skid-resistance during installation. A scored siliconized plastic release liner prevents the material from sticking together in the roll and is easily stripped away for installation.
NOTE: This product is required for all installations along the outside perimeter, valleys, skylights and anywhere there is an opening.
