If you buy a 900mm by 900mm from our website drop down menu with an UPSTAND then your structural opening would need to be 900mm by 900mm. As an example, the structural opening hole size that needs to be cut for this rooflight is the size of the rooflight you purchase from the drop-down menu, only if you purchase with a 150mm or 300mm upstand.
Alternatively If you buy a 900mm by 900mm from our website drop down menu WITHOUT AN UPSTAND (fit on builders upstand) then your external upstand size would need to be 900mm by 900mm, upstand width 75mm wide and 150mm high.
*Centre pane U-value is a measure of the thermal efficiency of the glazing type.
Part L Building Regulations require a U-value of at least 2.2W/m2K: Brett Martin Daylight Systems recommend the use of at least triple skin rooflights in all applications
