Wood Window Alliance specifications receive top rating

15 December 2014

Wood Window Alliance (WWA) specifications have been recognised in the BRE Green Guide for the first time.

The WWA said the A+ rating for standard softwood timber windows and A+ and A ratings for aluminium-clad windows show that WWA specification windows are more environmentally friendly, offering a longer planned service life and lower whole life costs than PVCu alternatives.

All WWA standard softwood timber windows for commercial and domestic buildings are rated A+.

Powdercoated aluminium-clad softwood windows with an internal water-based translucent coating are rated A+, while those with an opaque internal coating are rated A.
