Description
ASTM Standard High Quality synthetic roofing underlayment
Synthetic underlayment is a type of roofing material that is used as a secondary barrier against moisture penetration on roofs. It is typically made from polypropylene or polyethylene material. Synthetic underlayment is designed to be lightweight, flexible, and highly tear-resistant, making it easier to work with during roof installation.

Advanced Engineering
Wuxi Sentai Roofing Underlayment with its advanced engineering is highly recommended for mechanically attached, coated woven synthetic roofing underlayment for sloped roofs. Wuxi Sentai is specifically manufactured to replace the #15 Felt and #30 Felt.
Cooler Working Surface
Wuxi Sentai unique gray top layer which provides for a cooler working surface can be used under primary roofing materials to replace #15 Felt and #30 Felt. Wuxi Sentai high traction walking surface permits easier steep slope walk-ability, even during high condensation or moisture on the surface.
High anti skid bottom
Wuxi Sentai anti-skid bottom surface made with advanced polymers helps keep the underlayment intact and prevents the fabric from tearing while it is being fastened avoiding any leakages through the underlayment layer.
Exceptional Strength
Wuxi Sentai is 25 times stronger than #15 Felt and #30 Felt and 4x lighter than #15 Felt and #30 Felt. With a 7mil thickness, a 1000 square feet roll weighs only 23 lbs.! This super low weight combined with 48" width and 250 ft. run length means big savings in time and labor - over 30% faster to install than felt!. These unique design features, when coupled with Wuxi Sentai’s exceptional light weight and exceptional tear strength, allows the contractor to easily carry the roll up and down the ladder. Fewer laps, cuts, and roll handling means you can do more jobs in less time resulting in huge savings for you, the roofing contractor.
