DIFFLEX THERMO TPU ND underlay screen

Description

DIFFLEX THERMO TPU ND is a high-performance roof underlay screen, nail-tight, specially adapted to renovation. Composed of a polyester non-woven combined with a monolithic TPU/copolymer coating, it offers an optimal combination of waterproofing, breathability and robustness. Its integrated "SK" adhesive strips allow reliable bonding of overlaps without additional adhesive, reinforcing wind-tightness. Certified according to NF EN 13859-1 / 13859-2 and compliant with NF DTU 40.29, it meets the requirements of flexible roof underlay screens and is authorized for temporary watertightness during construction. Advantages Integrated nail-tightness, ideal in renovation. Temporary watertightness without tarpaulin during construction. Pressure rebalancing under the roof covering during high winds → limits the lifting of covering elements. Reinforced wind-tightness thanks to integrated SK adhesive strips. Protection against humidity of insulation and construction timber. Better summer comfort and limitation of parasitic air movements. Resistant to temperatures up to 100°C. 10-year warranty.
