Energy Rating

'A' Rated Window from Pearl

The "Pearl Energy Suite" Rating

After rigorous testings from BSI and extensive simulation testing, we are pleased to offer a range of products that all fall between the higher end specification of A, B and C-rated windows.


To make these changes we have had to firstly alter the make-up of the window frame itself. In the case of the A rated window, we have now included special foam insulation to the steel reinforcing chamber on the outer frame, and have had to specify special make ups of glazing to ensure optimal energy saving.

Window Energy Rating Label


Launched in March 2004, the Window Energy Rating label is similar to that used on many white goods in our homes, such as fridges and washing machines. Windows are scored on a scale of A – G, with an A rated building product being more energy efficient than one which is G rated. This allows individuals to quickly and easily choose the windows most suitable for their needs.


Energy efficiency

In an ideal world, A rated windows would be installed in each home in the UK. However, recognising that a balance needs to be made between the availability and cost-effectiveness of such products, those which are given a rating of C and higher are recognized as energy efficient, and can officially be endorsed with the Energy Saving Recommended logo.
