Building Regulation Compliance And Window Energy Ratings (WER)

Compliance with current building regulations is a vital part of every installation and can sometimes be complex. Using REAL Aluminium, meeting the requirements of Part L of current UK building regulations is easy as the entire range is compliant when installed with a double-glazed unit with a U Value of 1.2w⁄m2k and a solar gain of 0.71 or better that is manufactured using an Edgetech Super Spacer Bar or equivalent.


All REAL Casement Windows achieve an ‘A’-rating if the above glass unit is upgraded to low-iron glass.
The thermal efficiency of the REAL Aluminium range can be enhanced further by using higher performance double-glazed or triple-glazed units.
