Conservatory Roof Insulation
A breathable, sound-dampening cork layer applied to your conservatory roof — boiling summers and freezing winters become comfortable all year.

The problem
Why this matters
Polycarbonate and glass conservatory roofs are thermal disasters. Solid-roof conversions cost £8,000–£18,000 and often need building regs approval.
Our solution
How we fix it
We spray cork directly onto the existing roof panels (interior, exterior or both). It cuts solar gain, reduces rain noise dramatically, and improves U-value — without the cost or planning of a solid roof.
What you get
- Up to 60% cooler in summer, warmer in winter
- Cuts rain drumming noise by ~50%
- Typically a fraction of the cost of a solid roof
- Installed in 2–3 days, no planning needed
- Available in any RAL colour to match interior

Common questions
People often ask
- Does it look like plaster?
- It has a subtle suede texture — most clients love it. We can show samples on site.
- Will I need building regs?
- No — it's a coating, not a structural change. Solid-roof conversions need regs; ours don't.
