What actually happens during a SupaLite conversion, how it achieves such a low U-value while staying light enough for an existing conservatory base, and the tile, colour and roof window choices available.
A SupaLite conversion replaces a tired glass or polycarbonate conservatory roof with a solid, fully insulated tiled roof — so the room stops being a hot box in summer and a fridge in winter. Here's how the system works and what you can choose.
| Feature | SupaLite Tiled Roof |
|---|---|
| U-value | 0.15 W/m²K standard, 0.12 W/m²K enhanced |
| Weight | Around 46kg/m² — a lightweight aluminium-framed build, varies slightly by roof style |
| Construction | Precision aluminium framing with over 150mm of insulation, a waterproof breathable membrane and a lightweight tile finish |
| Tile finishes | ExtraLight Classic, ExtraLight Shingle or Tapco Slate |
| Guarantee | 10-year product guarantee, Building Regulations approved |

A solid tiled roof doesn't have to mean losing all the light a glazed roof gave you. The SupaLite system can incorporate roof window glazing panels or a roof lantern section within the tiled roof, so you can keep a glazed area over a specific part of the room — see our roof lantern & roof light sizes guide if you're considering a dedicated glazed roof instead of a full tiled conversion.
A standard 4m × 4m Edwardian conservatory typically takes around 3–4 days to convert, though this varies depending on the roof style and size — your installer will confirm a timescale for your specific conservatory.
No — SupaLite's lightweight tiled roof system weighs around 46kg per square metre, which is why it can typically sit on an existing conservatory base and frame without the extensive structural strengthening a traditional heavy tiled roof would need.
Our SupaLite tiled roof achieves a U-value of 0.15 W/m²K as standard, improving to 0.12 W/m²K with the enhanced specification — both well within Building Regulations requirements for a habitable room roof.
Yes — SupaLite's tiled roof system can incorporate roof window/skylight glazing panels or a roof lantern section within the solid tiled roof, so you don't have to lose all natural light from above.
