WELL Building Standard
Certificate type
13.1 mm thick vacuum glazing unit with P1A classification, a U-value of 0.4 W/m²K and an acoustic noise reduction of 40 dB.
Particularly suitable for applications in new builds or security conscious restoration projects where slim profile glazing is important.
LandVac Protect is specifically designed to achieve P1A security performance while also offering a slim profile, a centre pane U-value of 0.4 W/m²K, an acoustic noise reduction of 40 dB, and toughened durability. It’s a particularly suitable choice for authentic windows with extreme energy efficiency and security performance requirements.

LandVac Protect Vacuum Glazing Units:
LandVac Protect glazing is a suitable solution for heritage projects and buildings located in conservation areas as it eliminates the double reflection that makes standard double glazing unsuitable. This feature also addresses planning permission issues that arise from this visual disturbance.
Compared to slim double glazing, LandVac glazing is significantly thinner and lighter, making it easier to install and maintain. Additionally, it has high insulating properties, resulting in significant energy savings and a reduction in carbon emissions. This makes it an excellent choice for both new construction and retrofitting projects, allowing property owners to enhance the energy efficiency of their buildings without compromising their heritage or aesthetics.
