Celsius Solid Roofs
Contemporary, Sleek and Insulated - ideal for your modern glazed extension

The Celsius Solid Roof is an innovative tiled roof system for conservatory retrofits, as well as new tiled conservatory style extensions. Celsius Solid Roof is constructed using highly insulated SIPs (Structural Insulated Panels), deliberately avoiding the use of an aluminium framework to create a truly warm solid roof construction - with no possibility of cold bridging

Celsius Solid Roof Render - Kingspan TEK SIP Panels for High Insulation and Structural Performance


Kingspan TEK Building System panels consist of a high performance rigid urethane insulation core, sandwiched between two layers of Oriented Strand Board type 3 (OSB/3).  During manufacture, the insulation core is bonded by autohesion to the OSB/3 facings. This process provides more reliable and superior adhesion than the secondary bonding process used in the manufacture of most others SIPs
