Our mission is to exceed our customers' expectations in the home improvements market by delivering lasting value, thus being the first name considered and their supplier of choice.

Thermaglaze is the South West’s leading home improvement company. From our village showroom in Wiltshire, we provide an unrivalled range of energy efficient double glazing products, including A-rated windows, doors, conservatories and maintenance free roofline systems throughout Wiltshire, Somerset, Dorset and Hampshire.

We also offer high yield solar PV systems through our renewable energy division Thermaglaze Solar. In addition to providing an endless supply of green energy, these installations guarantee you a tax–free income for 20 years thanks to the government’s feed in tariff (FIT).

Established in 1988, we’ve been building a reputation by doing things our way. We promise transparent pricing, quality installations and customer care that’s second to none. That’s why we have over 20,000 loyal customers, with more joining us every day.
