Vacuum Glazing
Ultra-efficient slim vacuum glazing for heritage and modern homes
Vacuum glazing is an innovative, ultra-slim alternative to traditional double glazing, offering exceptional thermal performance while maintaining the fine, elegant appearance required for period and listed properties. Ideal for sash windows, casements and timber replacements, vacuum glazing delivers modern comfort with a discreet, heritage-friendly look.
Our vacuum glazed timber windows provide outstanding energy efficiency without compromising the original character of your home. As a family-run company for over 20 years, we supply high-performance glazing solutions to homes across Wiltshire, Dorset, Hampshire and Somerset.
We are specialists in listed buildings, working in all types of buildings from conservation areas to modern homes.
Benefits of Vacuum Glazing
- Exceptional thermal performance – similar to triple glazing, with a much slimmer profile
- Heritage-friendly appearance – ideal for listed buildings and conservation areas
- Ultra-slim units – typically 6–8 mm, fitting where standard double glazing cannot
- Excellent acoustic insulation – helps reduce external noise
- Energy-efficient – significantly reduces heat loss and draughts
- Condensation reduction – keeps internal glass surfaces warmer
- Perfect for restorations – retains the original look of traditional joinery
