Replacement Glass Roofs

Keep in mind the following four things when you’re thinking about exchanging your old roof for a brand new glass roof...

Tint – There is a very subtle tint in each glass roof and this tint helps to generate a certain ambience in a conservatory.  

U-Value – U-values measure internal heat loss. A very low U-value signals that the roof provides excellent thermal insulation.

Solar Heat Reflection – Some conservatory roofs have the ability to deflect excess solar energy produced by the sun away from the structure.

Light Transmission – This refers to the amount of light from the sun that gets in through a glass roof.

We tend to use clear glass a lot for north-facing conservatories as they draw in lots of external lights and warmth. The U-value of a clear glass roof is 1.0 W/m²K and it will therefore keep in lots of heat to keep you nice and cosy.

• U-Value: 1.0 W/m²K
• Solar Heat Reflection: 58%
• Light Transmission: 61%

There is the smallest hint of green in our aqua glass and this neat tint helps to prevent excess glare from the sun spoiling your view. As it is a self-cleaning glass it can look after itself and it is capable of reflecting up to 72% of the sun’s heat away. It will keep warmth in too thanks to its U-value of 1.2 W/m²K.

• U-Value: 1.2 W/m²K
• Solar Heat Reflection: 72%
• Light Transmission: 32%
