Laminated security triple glazing in Chepstow
Looking at laminated security triple glazing for a home in Chepstow? We survey, quote and fit across Gwent, and the NP16 postcode district is part of that.

Glass that cracks but stays in place, on the windows that need it. Laminated security triple glazing uses a pane made of two sheets of glass bonded to a plastic interlayer, so it cracks but stays in place when hit.
Winter light and glass choice in Chepstow

Rules for security glazing in Wales
Wales requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.
Before ordering: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.
How it works
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Chepstow
Do I have to have security glass?
Not for replacements, but it is worth it on ground-floor and easy-access windows.
Is laminated glass the same as toughened?
No. Toughened glass shatters into small blunt pieces; laminated glass cracks but stays in one sheet. Both are safety glass; laminated is better for security.
How long does it take to get laminated security triple glazing fitted in Chepstow?
After the survey, typical manufacture time is 4 to 6 weeks, and replacing the units usually takes a few hours to a day.
