TNi W400 (Green) - Glass-Fibre Based Shed Felt or Cap Sheet in Pour & Roll Systems

TNi W400 is a glass-fibre based, slate covered cap sheet, saturated and coated with oxidised bitumen. The membrane carrier is a glass reinforcement, giving the material good dimensional stability. The upper layer is coated with slate protecting material from ultraviolet exposure and lower layer is finished with fine grained sand. TNi W400 membranes are economical, glass-fibre based materials designed for use in traditional pour and roll multilayer roofing systems or as single layer waterproofing on shed roofs.
