1st Glass UK energy saving windows

Keep the bad weather out with brand new A-rated windows manufactured by 1st Glass UK. We use the latest energy saving glass sealed units, filled with Argon gas, maximum heat retention and minimum heat loss – perfect for those icy winter days while also keeping those heating bills down!

We manufacture our casement windows in our own factory, and also provide sliding sash windows for those more traditionally-styled homes. Our A-rated uPVC Sash windows have that ideal classic yet modern look.  With multi-chambered profiles for strength and energy saving, as well as robust multipoint locking, all our windows are as equipped to resist attack as keeping out the weather.
