Low U-values as standard with thermally efficient timber windows and doors

Offering double-glazed U-values of 1.2W/m²K as standard, and triple-glazed values of 0.8W/m²K, you can rest easy in the knowledge that your project will be more than compliant.

If you are seeking timber window and door products of outstanding quality that are more than Building Regulations compliant, with double-glazed U-values meeting new notional requirements of 1.2W/m²K across the board, get in touch with our friendly team at Bereco. Our experienced staff can provide you with a personalised quote in just 48 hours.

Following changes to UK Building Regulations on 15th June 2022, the requirements for all windows and external doors changed, in order to decrease the amount of carbon emissions generated by new homes by at least 31%. Windows and doors in new builds are now subject to a notional target of 1.2W/m²K (previously 1.6W/m²K) and a limiting standard of 1.4W/m²K (previously 2.0W/m²K).

When it comes to timber, there has been an exception, whereby a limiting standard U-value of 1.6W/m²K is valid up until 14th June 2023.

Although Bereco is ahead of the game with double-glazed U-values of 1.2W/m²K across the board, with this date fast approaching, it is likely that many products currently being sold by other window and door suppliers will not make the grade. Our standard double glazed windows are even more efficient than the stipulated new Part L limiting requirement, and our triple glazed products reach a U-value of just 0.8W/m²K.

To learn more about the changes to UK Building Regulations and what they mean for you, you can book onto one of our webinars. Our next available session will take place on Thursday 29th June 2023, from 12:30 – 1pm.
