What is the u-value of the glass

expertwebworld

A u value is a measurement of how well a building component is a window or a roof , keeps heat inside your conservatory.
Celsius clear and Celsius one have a U value of One compared to normal glass that is around two.
As there are no heat loss requirements on a conservatory or porch you do not have to have a performance glass to comply to building regulations (unless in Scotland).
To try and give an idea of how good Celsius glass is if normal 28mm double glazed units are around 2.0 u value Pilkington K glass is around 1.7 u value and Pilkington K glass with argon is 1.5 u value. Celsius Clear and One have a u value of One whilst Celsius elite has a u value of 0.9
It is all about balancing the side walls u value with the roof. There is no point in having a performance glass in the sides of the conservatory for instance Pilkington K glass with a u value of 1.7 and then putting a plain glass roof on top with a u value of 2.0. The only comparison for this is having a sauce pan without a lid where all the heat disappears through the roof.

Thanks. Gripping stuff. I've been losing sleep worrying I would never discover the u value of glass.
Are you planning a spamming?

And of course all your U value calculations are in accordance with EN410 and EN673 - A fact which is not mentioned anywhere on your website.
