Fully waterproof and air-tight, Wunderlay delivers protection against wind-driven rain and snow while resisting wind uplift pressures. It is the recommended choice for all Tapco Roofing products, including TapcoSlate Classic.\u003c\/p\u003e \t\t\u003cp\u003eManufactured from a durable twin-ply polypropylene spunbond and LDPE\/PP film, Wunderlay combines high tensile strength with excellent nail tear resistance for secure fixing. The absorbent underside prevents condensate drip-off, while the embossed upper surface minimises glare and allows accurate chalk line marking.
