Installed over roof void. Installation and rooflight fixing instructions supplied on order confirmation.

em.curbs are suitable for use with various roofing membranes, including single ply (bonded, welded or mechanically fixed), torch-on felt, hot melt, asphalt, GRP and liquid systems. Some designs feature smooth white internal finish to eradicate the need for further interior decoration – as well as a U-formed groove at the bottom of the curb to allow for a seamless fit with 12.5 mm plasterboard, eliminating risk of unsightly cracks at the rooflight and lining interface.

uPVC 350mm Splayed Oversleeve:

The em.curb 350/s is a rooflight upstand designed for use on roof refurbishment projects to oversleeve existing upstands. This benefits both the client and the installer by reducing the time taken to install the new rooflight and it normally means that the existing internal lining does not need to be disturbed. The em.curb 350/s simply sits on the roof outside the existing upstand after removal of the old glazing. If the existing roof construction contains controlled materials or can not be disturbed for other reasons, the em.curb 350/s Oversleeve will help to overcome this.
