How is CosyPanels different from multifoil insulation?
Conservatory roof insulation generally falls into three categories: internal multifoil insulation fitted beneath the existing roof, insulated replacement roof panels, and complete tiled/solid roof conversions.
CosyPanels is an insulated replacement-panel system designed to replace existing glass or polycarbonate panels without requiring a heavy tiled roof.
Benefits of CosyPanels® Conservatory Insulation Panels

CosyPanels® conservatory insulation panels are precision made from lightweight materials. Within every panel is a thick layer of insulation, which is densely packed. This will help to prevent the warm weather making your conservatory too hot during the summer.

Insurance-backed guarantee
CosyPanels is accredited by the Home Improvement Consumer Protection Scheme (HICS), giving homeowners an additional layer of independent protection. Once your completed installation is registered and your HICS Insurance-Backed Guarantee certificate is issued, the guarantee can protect you if the original installer were to cease trading and could no longer honour the terms of its own written guarantee. HICS accreditation also means installers are vetted before acceptance and customers have access to independent dispute-resolution support, providing extra reassurance before, during and after installation of your conservatory roof insulation.

Mr and Mrs Allen contacted us to discuss roofing options for their outdated polycarbonate roof of about 12 years old. The solution provided was to replace the roof with CosyPanels® conservatory roof panels. This would not only replace the roof but would also benefit the use of the conservatory as the Allens were finding it too hot or too cold making the conservatory at times unusable. The result was a new roof with insulation which…
Mr and Mrs Allen
Due to a couple of leaks and discolouration of the roof we were contacted to supply a replacement alternative roof due to the inherent issues Mr and Mrs Mercer faced with polycarbonate. They did not want to continue with the issues they had with noise and temperature control. CosyPanels® provided the solution at a cost comparative to polycarbonate which made the decision easy. This solution gave a…
Mr. & Mrs Mercer
The polycarbonate roof became a harvest for bugs and moisture. Over the years the polycarbonate was effective at keeping the elements out but was a real problem at providing a stable climate controlled space. We were contacted to demonstrate our innovative product which now replaces this out dated technology. We installed this solution in just one day and the results made a huge difference to the Walter’s…

Polycarbonate vs glass vs tiled roof vs multifoil ceiling vs CosyPanels®
How do the main options compare?
Polycarbonate is cheap but loses heat and overheats. Glass looks smart but still overheats: we regularly replace blue and grey solar-control glass roofs where customers were still too hot in summer. A tiled roof insulates best but costs the most and usually needs structural work. Multifoil isn’t a roof upgrade at all: it’s an internal ceiling fitted underneath your existing roof, which stays exactly as it is above it. It only marginally improves insulation, and experts warn that sealing the roof void can trap heat and moisture, risking condensation, damp and damage to the original structure. CosyPanels® replace the panes in your existing frame, upgrading the roof itself from one day.
| Polycarbonate roof | Glass roof | Tiled roof | Multifoil ceiling | CosyPanels® | |
|---|---|---|---|---|---|
| What it is | New plastic roof sheets | New glazed roof units | Solid roof rebuild | Ceiling fitted under the old roof | Insulated panels in your existing frame |
| Summer comfort | ✗ Overheats | ✗ Overheats, even with tinted solar-control glass | ✓ Cool | Partly | ✓ Cool |
| Winter warmth | ✗ Loses heat | Better if modern units | ✓ Warm | Marginal | ✓ Warm |
| Rain noise | ✗ Loud | Quieter than polycarbonate | ✓ Quiet | Partly | ✓ Quiet |
| Risk to your roof | Discolours with age | Sealed units can fail and mist up | Heavy load on the frame | ✗ Can trap heat and moisture under the old roof | Lightweight, under 8kg/m² |
| Typical cost | £6,300+ | £9,450+ | £7,875+ | £2,000–£4,500 | From £3,146 |
| Structural work | None | Depends on the frame | Usually needed | None | None in many cases |
| Fitting time | 2–5 days | 2–5 days | 4–5 days | Varies | From 1 day |
