LandVac Enhance Vacuum Glazing Units:

LandVac Enhance glazing is a suitable solution for retrofit of heritage glazing in listed properties 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 longer lasting, 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 product is an excellent choice for retrofitting projects where it's plugless design and low sightline fit existing rebates, allowing property owners to enhance the energy efficiency of their buildings without compromising their heritage or aesthetics.


LandVac Enhance heritage vacuum glass can also be fitted into new windows and new sashes, where it enables Heritage windows to perform at similar levels to modern double and triple glazed windows. The acoustic performance of LandVac Enhance vacuum glass also reduces noise and improves occupant comfort.
