LandVac Heritage glazing is an ideal 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. Additionally, its insulating properties are far superior, 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.
LandVac Heritage also offers huge benefits in sound attenuation and acoustic performance which can typically only be found in specialist triple glazing.
