RUC Roofing Underfelt Collar

Ensuring your window is completely watertight.

One of the most important things for a secure roof window is making sure it’s properly sealed where the roof and window meet. The YARDLITE RUC roofing underfelt collar does just that. Made from tear-resistant polystyrene and coated with a vapour-permeable polyurethane layer, it offers excellent water tightness while still allowing the roof to breathe. Built to handle tough conditions, it’s been tested to withstand temperatures from -40°C to +80°C and even heavy rain. Plus, the RUC collar comes pre-cut to fit the roof window, making installation faster and easier.
