Cream Sash Horn Casement,

Our uPVC windows with sash horns come in sculptured (Ovolo) 70mm profile frames. These frames can accommodate 28mm double-glazed units, with the option to upgrade to Pilkington 6.8 Optiphon soundproofing glass. The design also includes Secure by Design locking systems for enhanced security. Internally beaded and fully welded, these windows provide superior strength at the corners and joints between mullions and transoms.

Thermally Efficient Insulated Foam Tape

ISO-BLOCO HYBRATEC advanced insulation foam tape is applied to the front of the frame edge before installation. It effectively expands to fill gaps ranging from 3mm to 14mm, sealing the perimeter between the brickwork and frame. This significantly reduces energy leakage from the window area. Additionally, the tape guarantees UV stability for ten years, with a life expectancy of 40 years, far outlasting most external low-modulus silicones.

Roy and team did an excellent and professional job replacing 3 front windows, making the change unnoticeable from the outside. They were worked with challenges getting large frames into the upstairs room and were courteous throughout. Would recommend.

Roy and his team fitted new windows and French doors in our house earlier this year (we wanted to live with them for a while before reviewing!). We are really pleased with the quality of the windows and the service from Roy. He's a real gent to deal with and is punctual and professional. His quote wasn't actually the lowest but he was the only one to supply full details of materials, give fire safety and security advice, send a detailed quote etc. Thank you Roy

I got quotes from a few companies however Peter was the only one who followed up to my questions on email so I decided to go with Southeast Windows. I am super glad I did, as Peter was professional and I am really happy with the work done in installing a new PVC backdoor and replacing glass in several windows. Peter was knowledgable, friendly and didn't take advantage of my lack of knowledge of window and door installation like some other builders have, being a first time home owner.I wouldn't hesitate to recommend Peter and Southeast Windows, I will for sure be using them again if I need. Thank you Peter!
