We are proud to introduce Celsius Solid Roof – 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 Roofs are bespoke manufactured to precisely meet project requirements and come supplied in kit form for convenient and speedy assembly on site.

The system has been designed using proven, high quality components, supplied by the leading companies in their fields: The Envirotiles (available in Black, Dark Brown or Terracotta colours), Kingspan TEK Building System structural insulated panels (SIPs) and Rapierstar stainless steel fixings.

Designed to be fast to fit, Celsius Solid Roof can be weathertight in a few hours, and using a patented and environmentally-friendly tile system that does not require battening, installations can be finished quickly, with the minimum of disruption for the homeowner.

An exclusive range of ridge and hip covers complement the Envirotiles range. Precisely colour-matched, they are custom-made to exacting specifications from 100% recycled polypropylene. This uniquely complete roof tiling system means that there is the ideal component for every part of the roof – leading to finished roofs that look better and are complete in less time.

Standard PVC-U fascia and guttering can be used to finish the Celsius Solid Roof – in a range of colours, all supplied as part of the roof kit. However the system can accommodate most fasicas and guttering styles if required.

The Celsius Solid Roof is constructed using Kingspan TEK panels.These Structural Insulated Panels (SIPs) interlock together to form a strong, highly insulated structure. A breather membrane sits underneath Synseal Envirotiles producing a perfect weathertight finish.
