Upgrade iconic structures with confidence
Picture the soaring glass of Liverpool Street Station or the brutalist elegance of the Barbican. Upgrading structures like these requires serious engineering rather than standard double glazing.
LandVac delivers world-leading thermal insulation with U-values as low as 0.4W/m2K. You get modern energy efficiency packed into a profile so slim it is practically invisible.

The Headache of Heritage Retrofitting
Why sacrifice energy efficiency for heritage when you can have both?
Retrofitting older properties is rarely straightforward. Planning officers want original windows preserved at all costs. Building control demands modern thermal performance.
Slim double glazing is basically the flaky ex of the window world. It promises the earth but usually leaves you with failed seals and disappointed clients. Standard double glazing is simply too thick to fit into original timber frames, while single glazing bleeds heat and money.
Trying to keep everyone happy usually leads to expensive compromises or rejected planning applications.
The Ultimate Architectural Solution
Vacuum glazing changes the rules completely. By extracting the air between two panes of glass, LandVac achieves incredible performance in a fraction of the space. It is fully toughened as standard and available in custom shapes to suit most architectural quirks.

No longer limited to single glazing
“Too often, heritage projects have been limited to single glazing with poor thermal performance or slim double glazing prone to early failure.
Vacuum glazing, has provided a reliable solution. It delivers the authenticity required for strict planning approval alongside the performance needed to meet advanced retrofit targets.
The Mews House project – which achieved an 82% measured energy reduction and airtightness close to 1 m³/m²/hr @ 50Pa – is a prime example of how this approach works in practice.“

Traditional looking modern windows
“The prospect of installing cold and draughty single-glazed windows was just not
acceptable to us. Whilst we were fully committed to maintaining the historic
integrity of our home, we also wanted to benefit from a warm and pleasant
living environment.
We looked at various window types. The thickness of standard double glazing was
definitely out of the question for the planners.
But we then discovered LandVac energy efficient vacuum glazing with a 0.3 mm airgap. For us, these traditional looking, modern windows really did tick all the boxes …so we looked no further!

The most authentic looking single-glazed look
“Of all the replacement window possibilities we explored, we thought that these had the most authentic single-glazed look. We were really impressed by the slimness and performance of the vacuum glazing
We are really pleased with our new windows. They have transformed the external look of the farmhouse, eliminated the draughts we used to put up with, and greatly improved thermal insulation, leaving the house warmer and much more comfortable to live in. The vacuum glazing has also helped make the house a lot quieter, so that the noise from the nearby road is now almost completely eliminated.”
