Avant Pro Roof

A beautiful amalgamation of solid and shaped glass brought together seamlessly. This is the first roofing solution designed to give you the flexibility of a solid roof together with shaped glass so that your room can benefit from maximum natural light. Externally the Avant Pro Roof is finished in a classic grey to complement any house style, whether you're after a contemporary or traditional look.

The Avant Pro Roof is quick to install, meaning minimal disruption to your home compared with general solid roof installations. Our new roof is extremely thermally efficient due to its advanced design and what's more the Avant Pro Roof is fully compliant with building regulations (the conversion of a glazed conservatory roof in to a solid one requires official building regulations permission).
