Technical Information

Glazing Information:

*Centre pane U-value is a measure of the thermal efficiency of the glazing type.

#Ud-value is a measure of the thermal efficiency of the whole rooflight (calculated in accordance with NARM Technical Document NTD2).

~Glass glazing option is not available with the access hatch option and limits other opening options depending on size

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.

Tint:

To see the light transmission properties of the polycarbonate rooflight, look at the below table:

 

Clear – high visibility, Light transmission maximised, Clarity of vision of views and objects through the dome maximised.

Opal – diffused light and solar control, Privacy in tandem with elevated levels of diffused light transmission, Reduced solar heat gain and no solar glare, Restricts sight of views and materials through the dome.

Patterned – privacy, Privacy fused with elevated levels of light transmission, Reduced daylight, Impairs vision of sights and objects through the dome structure.
