At Warm Roof Pro, we use C24 grade structural timber in all our roofs. Timbers are machined to the highest standards using state of the art woodworking machinery.

Warm Roof Pro use C24 timber for its eaves beam, wall plates, eaves infills, ridges, Hips, and structural jointing timbers. None structural joints in the panels use SIP cassettes.

Hips, and ridges are cut to the angles required, then bonded with pu adhesive, and mechanically fixed in our factory.
