The U-value of a product measures how effective its insulation properties are. The lower the U-value the better insulated the product is.
All sizes of the Ultrasky Flat Skylight currently exceed Building Regulation requirements.
G-value (sometimes also called a Solar Factor or Total Solar Energy Transmittance) is the coefficient commonly used in Europe to measure the solar energy transmittance of windows. A g-value of 1.0 represents full transmittance of all solar radiation while 0.0 represents a window with no solar energy transmittance (the lower the g-value the better).
The Ultrasky Flat Skylight’s G-value is 0.5 which is similar to most solar control glazing.
Currently the Ultrasky Flat Skylight is only available as a fixed product.
Top tip: For an opening option why not consider the Ultrasky Lantern with roof vents.

Ultrasky Flat Skylight can be fit at heights up to 13m above floor level when the overall glazing area is 3m2 or less. For glazing areas greater than 3m2 the maximum fitting height is 5m above floor level.
Self cleaning glass is only available on glass options with a 10 degree angle or above. As Flat Skylights are 4 degrees, this means self cleaning glass is not needed.
The Ultrasky Flat Skylight is designed to meet current British Standards for overhead glass installed less than 5m above the finished floor level (it is not designed to be walked on). British Standards state that inner panes on overhead glass units must be laminated in applications over 5m above floor level (increased to 13m in limited circumstances) or are located over a body of water (such as swimming pools).
The use of toughened inner glass panes in other applications below 5m above the finished floor level is permitted in British Standards, although a risk assessment should be carried out and confirmation provided that this does not present additional risk to those below the rooflight.
