LandVac Enhance Glazing: The Clear Choice Reglazing in Heritage and Conservation Projects

LandVac Enhance 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.

The unit has low sightlines and no evacuation plugs, so it fits neatly into most existing rebates with minimal work.

Compared to slim double glazing, LandVac Enhance heritage glazing is significantly thinner, making it easier to install without deepening rebates. It also comes with a 15 year warranty and an expected service life far beyond that, completely the opposite of the high maintenance and replacement requirements of slim double glazing.

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.
