What Are DIY Insulated Conservatory Roof Panels?
ThermoPanels are PVC-UV / XPS / PVC-UV sandwich panels, specifically engineered for conservatory roof insulation in the UK climate.
They are designed as a direct replacement for existing polycarbonate or glass roof panels, allowing you to upgrade thermal performance without altering the conservatory structure.
Panel construction at a glance
- Outer layers: White PVC-UV on both sides (UV-protected, moisture-resistant)
- Core: High-density XPS (extruded polystyrene foam)
- Result: Lightweight, strong, weather-resistant, and thermally efficient panels
This construction delivers a significantly lower U-value than polycarbonate or glass, helping to stabilise temperatures and reduce heat loss.
