What Is LandVac Vacuum Glazing?
At its core, LandVac is a new generation of glazing that outperforms both double/triple glazing and other vacuum glazing brands while remaining remarkably slim.
- Structure – two panes of tempered glass separated by a vacuum layer, eliminating conduction and convection heat transfer.
- Thickness – at just 8.3mm, it is less than half the size of typical double glazing.
- Thermal performance – LandVac vacuum glazing delivers U-values as low as 0.4 W/m²K, exceeding triple glazing and even rivalling other vacuum-glazed units available today.
- Acoustic performance – LandVac glass cuts out intrusive external noise, enhancing sound insulation and creating calmer, more comfortable interiors.
Traditional insulated glass units rely on inert gases like Argon or Krypton to slow down heat transfer, but these gases can still carry heat via convection. LandVac removes the air entirely, creating a high-vacuum environment where heat simply cannot travel, resulting in unparalleled energy efficiency.
This is why a unit can be thinner than a single pane of old-fashioned glass yet provides insulation equivalent to a solid brick wall.
Key Features of LandVac Vacuum Glazing
LandVac is packed with innovative features that set it apart from conventional glazing and other similar products in the market:
Exceptional thermal insulation
Delivering U-values as low as 0.4 W/m²K, it offers thermal insulation performance that is 2-4 times better than insulated glass and 6-10 times better than single-pane glass. It also exceeds triple glazing and even other vacuum glazing brands without the extra thickness, making it a reliable energy-efficient choice for reducing long-term heating costs.
Ultra-slim design
At only 8.3mm thick and weighing 20kg/m2, LandVac fits seamlessly into slim or heritage frames where double or triple glazing would be unsuitable. This makes it ideal for listed properties and conservation projects.
Lightweight construction
Despite its strength, LandVac is lighter than equivalent triple-glazed units, making it easier to transport, handle, and install. This helps reduce time and labour costs. It also puts less stress on your window hardware and hinges, making the installation process safer and more efficient for our teams and your property.
Outstanding acoustic performance
Noise pollution is one of the most common urban complaints. Its vacuum cavity enables LandVac to achieve a weighted sound reduction index exceeding 39 dB, significantly improving indoor comfort through enhanced sound insulation.
Durable tempered glass
Each pane is made from tempered glass and features a resilient metallic edge seal, offering enhanced safety and long-lasting durability. With a 15-year guarantee provided by CN Glass, LandVac is engineered for over 25 years of reliable performance, longer than other vacuum-glazed units.
Condensation resistance
Its advanced construction helps prevent condensation even when the temperature difference between the two sides exceeds 70°C. With LandVac glazing, you can maintain crystal-clear visibility while still allowing ample natural light into your space.
Low maintenance
With fewer failure points compared to traditional double glazing, it requires minimal upkeep and is simple to clean. This ensures lasting clarity and performance.
Eco-friendly manufacturing
CTI testing reveals that LandVac is lead-free, hazard-free, and food-grade safe. Reducing energy use also helps cut long-term carbon emissions. It is a truly green choice for the environmentally conscious property owner, contributing to a lower carbon footprint for the entire building.

Frequently Asked Questions
- How does LandVac compare to double and triple glazing?
- LandVac stands out among vacuum-insulated glass options due to its thinner profile, stronger sealing technology, and superior thermal performance, making it ideal for both modern and heritage applications. While triple glazing can reach U-values of 0.6 or 0.8, it is often 32mm to 44mm thick. LandVac achieves a 0.4 U-value at just 8.3mm, providing superior warmth without the heavy aesthetic or the need for new, bulky window frames.
-
How thick is vacuum double glazing?
- LandVac units measure just 8.3mm or less than half the thickness of standard double glazing. This ultra-slim profile is what makes it uniquely suitable for fitting into existing sashes without the need for extensive joinery work or structural changes.
-
Can LandVac help with heritage compliance?
- Yes. Our LandVac heritage glazing solutions are specifically designed to meet conservation requirements while improving efficiency. We also support clients in addressing planning permission concerns with detailed technical documentation.
-
What U-value can it achieve?
- It delivers U-values as low as 0.4 W/m²K, putting it above the best triple glazing and vacuum glazing products in the market. This means LandVac provides thermal insulation that is significantly more effective than standard 24mm double glazing, which usually sits around 1.2 W/m²K.
-
Does it require special window frames?
- No. Its slim profile means LandVac can often be retrofitted into existing frames, saving time and cost. Whether you have timber, aluminium, or uPVC frames, it can usually be accommodated with only minor adjustments to the glazing beads.
-
How long does installation take?
- Project times vary, but most installations are quicker than fitting bulky triple glazing thanks to LandVac's lighter, thinner design. A typical residential upgrade can often be completed in just a few days, depending on the number and size of the units.
-
Is it environmentally friendly?
- Yes. Expert testing reveals that LandVac glazing is lead-free and manufactured to eco-friendly standards. By significantly reducing energy consumption for heating and cooling, it is one of the most effective ways to lower your home's carbon footprint.
-
How does it handle thermal expansion?
- Because LandVac uses tempered glass and a flexible edge sealing technology, it can withstand extreme temperature fluctuations without cracking or losing its vacuum. This resilience is tested in environments ranging from -40°C to +70°C, ensuring reliability in the most unpredictable UK weather conditions.
-
Are the 'pillars' visible in its glass?
- LandVac uses micro-pillars to keep the glass panes apart, which are remarkably small and arranged in a grid that becomes virtually invisible once installed. Most users do not notice them in daily use, as they are specifically designed to blend into the background and maintain perfect visual clarity.
-
What are the units’ expected lifespan?
- While the warranty is for 10-15 years, the units are engineered to last for over 25 years with minimal maintenance. The vacuum seal is designed for extreme long-term stability, ensuring the glass performs as well in year 25 as it does on the first day of installation.
-
Is LandVac toughened glass?
- Yes, both panes of glass in a LandVac unit are fully tempered, making them much stronger and safer than standard annealed glass units. This is a critical feature that distinguishes LandVac from other VIG brands, offering superior impact resistance for high-traffic areas and low-level windows.
