An underfelt foil collar that ensures 100% water tightness around your window 

How do I ensure the tightness of my roof window? 

A key factor in the tightness of your roof window is water tightness at the critical point where roof window and roof meet. The RUC collar is manufactured from tear-resistant polystyrene with a vapour-permeable polyurethane coating. This provides the highest level of tightness while maintaining a high level of breathability. The RUC collar retains its properties even under extreme atmospheric conditions. Its resistance has been tested in a temperature range of -40°C to +80°C, and in the most torrential rainfall.

Saves time during installation

The RUC collar is pre-cut to the dimensions of the roof window, reducing window installation time. Please ensure that collar and window sizes are compatible when making your selection. The RoofLITE+ RUC collar is compatible with all RoofLITE+ roof window types.

The RUC collar performs excellently in combination with the IFC/IFCS insulating foam collar. Together, they guarantee an optimal level of window tightness and insulation.
