The Grace Tri-Flex XT is a woven, synthetic, water-shedding underlayment that is high performance. It is more than 20 times stronger than #30 felt. Tri-Flex XT is coated on both sides with a new and enhanced coating formulation made up of slip-resistant polymer for exceptional foot traction. This membrane is tough and weather-resistant and is constructed to function in the harshest weather circumstances in North America. Tri-Flex XT is also built to withstand high wind conditions while also covering more area and being lighter than #30 felt. This underlayment can be used in combination with GCP self-adhered underlayments and is mechanically attached to the roof. It also provides a reliable base for the application of roof coverings that are mechanically attached. This membrane serves as a secondary watershed to prohibit leaks if water penetrates the main roof covering.
