What Is the Price of Insulated Conservatory Roof Panels?
The cost of insulated conservatory roof panels depends on several factors:
1️⃣ Panel Thickness
ThermoPanels are available in multiple thickness options, typically ranging from 16mm up to 35mm.
In most cases, replacement is like-for-like in thickness — meaning:
- 25mm polycarbonate → replaced with 25mm insulated panel
- 35mm glass → replaced with 35mm insulated panel
The thickness depends on your existing glazing bars and roof system.
Thicker panels generally provide:
- Better insulation performance
- Improved temperature control
- Enhanced noise reduction
2️⃣ Panel Size
Standard panel sizes available at Conservatory ThermoPanels are:
✅ 2000 × 1000 mm
✅ 3000 × 1000 mm
✅ 3000 × 1500 mm (16mm & 25mm thickness only)
✅ 3000 × 2000 mm
✅ 4000 × 1000 mm
✅ 4000 × 2000 mm
These size options allow flexibility for most conservatory roof layouts, lean-to structures, garden rooms, and other projects.
3️⃣ Quantity Required
Naturally, the total project cost depends on how many panels your conservatory roof requires.
A small lean-to conservatory will require fewer panels than a larger Edwardian or Victorian style roof.
