Aluminium windows are known for their strength, durability and sleek modern appearance. But maintaining their thermal performance can be tricky, especially as older double glazing begins to lose efficiency. The good news? You don’t need to change your frames. Simply reglaze with LandVac vacuum glazing for a smarter solution.

What’s the issue with ageing double glazing?

Double glazing is better than single glazing, but it’s not built to last forever. Over time – typically 10 to 15 years – the insulating gas inside the unit starts to escape.

The glass might look fine, but the insulation won’t be. That means more heat loss, higher bills and less comfort.

What’s the smarter option?

Reglazing with LandVac Optimum S1.10 (25.1mm) dramatically improves insulation without needing to touch your aluminium frames. It’s high-performance vacuum glazing that slots straight into existing setups.

By upgrading from standard double glazing to LandVac Optimum S1.10, you can improve the overall U-value of your window from 3.76 W/m²K to 2.22 W/m²K. That’s a big win for comfort and efficiency – and it keeps the clean, modern look of your aluminium windows intact.

Looking for even more performance?

If you want to go a step further, consider 8.3mm LandVac Enhance with VacuGask™. It’s thinner, lighter and easier to install, and still delivers the thermal boost you need.

Why choose LandVac Enhance with VacuGask™?

  • Market-leading warranties: VacuGask™ provides a perfect seal, extending product life.
  • Stable performance over decades: Vacuum glazing doesn’t degrade like gas-filled units.
  • Minimal adjustments required: Slim enough to fit most existing aluminium window setups.
