Have you been on the lookout for new windows for your home that are a good match to the rest of your property?

Would you like to have your replacement windows supplied and installed by the same company?

And would you appreciate windows that are highly energy efficient, and that therefore keep your home warmer whilst saving on your energy bills?

These are questions to which so many of our customers can say “yes”, and here at Thermoglaze UK, we specialise in the supply and installation of windows that have an A rating according to the Windows Energy Ratings(WER) scheme of the British Fenestration Rating Council (BFRC).

Secured By Design (SBD)

Established in 1989, it is a police backed initiative focusing on the design and security for new and refurbished home as well as commercial premises.

Strongly supporting the principles of ‘Designing out crime’  to not allow an opportunity for anyone.

Secured by Design (SBD) status is awarded to products that are designed from the start with security features set as a top priority. Lainiar products that hold this certification are heavily tested to meet the requirements of Secured by Design and the Association of Chief Police Officers.

A rated windows are windows that have been awarded the top grade as part of the BFRC’s scheme, with G being the lowest possible rating. As a matter of fact, the most recent Building Regulations dictate that new homes should have a rating of no lower than C, which is a good starting point when you are looking to replace your own home’s windows.

Having said that, it also goes without saying that you’ll want to make the right choice of replacement windows, first time out – and that ideally means investing only in A rated windows.

Signature is a top installer and supplier of affordable, not to mention good quality, A rated windows.

Why should I purchase A rated windows from Thermoglaze UK?
