Triple glazing for period homes and conservation areas in Newtown
We arrange surveys and fitting of period-style triple glazing in Newtown and the SY16 area, with a written, fixed quote after a free survey.

Heritage-style frames and plain advice on consents. In a conservation area, replacing windows on a house is often permitted development if the new windows look similar to the old ones, but councils can remove those rights with an Article 4 direction.
Winter light and glass choice in Newtown
By midsummer Newtown has about 16 h 50 min of daylight, but in December only around 7 h 39 min, with the noon sun at about 14°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for period homes and conservation areas in Wales
The rules for replacement windows in Wales are set by Approved Document L for Wales (2022 edition, with 2024 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. 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
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- 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 Newtown
Can I put triple glazing in a listed building?
Usually not as a replacement. Listed building consent is needed and is often refused for original windows. Secondary glazing is the common alternative.
Do you help with planning applications?
We provide drawings, specifications and samples you can use in an application. The application is made by you or your agent.
How long does it take to get period-style triple glazing fitted in Newtown?
After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.
Do I need permission for period-style triple glazing in Newtown?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
