Black tiled roof replacement in Ashton-under-Lyne


Whether you’re looking to build a new conservatory or replace an existing conservatory roof, you cannot go wrong when choosing a tiled roof. A new roof will insulate your conservatory against the cold and external noise. Giving you an all-year-round comfortable living space. The combination of internally plastered ceiling and external tiling also results in an area that feels like an extension of your current home.

With Guardian and Supalite tiled roofs available, you may be unsure which conservatory roof system is best. At Droylsden Glass, we offer both and thought we would take a closer look and answer the most common questions searched for online.

Guardian roof tiles vs Supalite roof tiles

Guardian roofs come with two types of tiles: Slate and Metrotile. Both styles come in 5 different colours to match a wide range of properties with ten options. Guardian tiles also come with a 40-year weatherproof guarantee.

Supalite roofs come with either Tapco or Extralight tiles and in 7 different colours. Plus, the tiles are guaranteed against the weather for 50 years.

Does a Guardian or Supalite conservatory roof have good thermal performance?

Guardian and Supalite replacement roofs have the same U-values of 0.18 W/m2k, meaning they both have the same energy rating.

The Guardian Conservatory roof reaches the 0.18 W/m2k measurement using a 3-layer insulation method that includes an exterior grade plyboard and a breathable waterproof membrane. 

A Supalite replacement conservatory roof achieves impressive U-values by using insulated plasterboard and EPS insulation.

If you want an additional thermal boost, you can opt for the Supalite Plus, which gives an improved U-value rating of 0.15 W/m2k, the best energy rating available for a replacement conservatory roof. 

Do Supalite or Guardian Conservatory roofs allow natural light?

Supalite and Guardian Conservatory roofs offer plenty of rooflight options to increase natural light and ventilation.

The Supalite Sky Vista is a hybrid conservatory roof with full-length glazing panels, as Guardian roofs can be fitted with large Solstice skylights to enhance light intake significantly.

You can have the best of both with these replacement conservatory roofs, the thermal performance of a solid roof with the natural flood of light just like a traditional conservatory.
