Join our CPD Roadshow!
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.
Find out about a world-leading thermal insulation with U-values as low as 0.4W/m2K, but with profiles easily mistaken for single glazing.
The industry is starting to catch up.
Historic England has approved it in its guidance.
They say, “make something great and people will come”
But that doesn’t seem to be working…
So instead, we’ll come to you!
That is why we are bringing together industry specialists to share practical knowledge, technical insight and real project experience.
And taking this show on the road to visit a heritage hotspot near you!

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.
Trying to keep everyone happy usually leads to expensive compromises or rejected planning applications.
We’re ready to cure that headache!
What you'll find out:
- What is vacuum glazing?
- How is it different to other glazing types?
- How does vacuum glazing perform?
- What makes this the ideal solution for heritage windows?
- Where has vacuum glazing already been approved?
- How are manufacturers and installers incorporating vacuum glazing into their products?
Roadshow locations:

Who are the Edinburgh Speakers?
Our Edinburgh event will have a talk from industry experts, including:
2. A local glass and glazing specialist and supplier
3. A RIBA registered Architect and Company Director
5. A manufacturer/installer that is incorporating vacuum glass
Speakers and topics:
An Introduction to Vacuum Glazing from Amy Boutle at Vacuum Glazing
An in-depth introduction to vacuum glazing and its growing role within modern and heritage glazing applications.
The session will cover:
• What vacuum glass is,
• How the technology works,
• How it compares to single glazing and triple-glazing.
Plus, an understanding of cost comparisons, key applications within residential and commercial projects, listed buildings, conservation areas, and retrofit schemes.
Renovation of sash and case windows, Wullie Mallen, Wm.Mallen Joinery
WM.Mallen Joinery uses LandVac Vacuum Glazing daily and has been a distributor of it since 2020.
Karen Nugent, ARB, RIAS accreditation in Conservation Architecture
Karen will discuss the challenges of using vacuum glazing within conservation areas and in heritage properties.
Karen has recently used vacuum glazing on a project and loves to work with it, and wants to use it in more projects going forward and introduce it to more customers in Scotland.
Kit Campbell, Fellow of the Royal Incorporation of Architects in Scotland: Case Study
Kit retired four years ago but has replaced all of of his homes glazing with vacuum glazing and will never look back.
The presentation will be a case study on his own house, where WM.Mallen Joinery fitted LandVac in the units, which were 2650mm x 1480mm!
Laura Milbourne MRICS of Period Home Projects
Planning for Heritage Windows by Laura Milbourn, MRICS of
Period Home projects
Laura has been a qualified Chartered Surveyor for 22
years and has worked in London for many years, refurbishing prime residential
properties.
A passion for heritage buildings with their period
features led her to set up her Heritage Consulting business, Period Home
Projects, in 2014.
Laura will be discussing:
- Why it’s important to protect original/significant windows (even when replacement would be more profitable)
- Assessment of windows – who does it, why and when needed
- Consents – what needs consent and what doesn’t – listed buildings, conservation
areas and undesignated heritage assets - Stages of the planning process

Trusted Partnerships
LandVac is trusted across the UK and supported by six specialist regional distributors. These experts have the technical knowledge to help you specify the right glass for any complex project. We have also partnered with Schott glass to develop a groundbreaking new monolithic vacuum unit. Real expertise backs every single installation.
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!
Chris

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.”
