The Ultrasky Aluminium Flat Skylight provides an element of style to extension and orangery roofs by flooding natural light into previously dark gloomy rooms. Its distinctive sleek, frameless edge to edge glass gives a stunning contemporary look that complements the style of the roof and allows the largest possible amount of light into the room. Ultrasky Flat Skylight looks frameless from the inside, giving a bright open room feel. The fully insulated aluminium frame with ‘Warm Frame’ technology and high performance noise reducing glass* means the flat skylight blocks out noise from the outside and is unrivalled in thermal efficiency.

The U-value of a product measures how effective its insulation properties are. The lower the U-value the better insulated the product is.
Building Regulation Part L relates to limiting heat gain and loss (u-Value compliant). In order to be compliant U-values must be no greater than 1.6 W/M2k in England and 1.4 W/M2k in Scotland.
Ultrasky Flat Skylight's fully insulated frame with 'Warm Frame' Technology and low-E High performance glass with a U-value of 1.0W/M2k means the Skylight has an overall u-value of 1.2 W/M2k, making it compliant with building regulations in England and Scotland.
Top tip: Always check the overall U-value of the skylight/roof light product, not just the glazing element.
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.
