LandVac Heritage Vacuum Glazing Units:

LandVac heritage 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 heritage 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.
