Glassmarque's unique protection system protects valuable windows whilst enhancing the look of the building's exterior. It is lightweight, non-ferrous, easily removable and has a full perimeter ventilated frame. Previous systems lacked any form of ventilation, causing damage when heat built up against the glass. Our team are experts in installing to brick and stonework in churches and listed buildings and use no mastics, silicones or iron fittings which can cause staining to stone or brick or make windows difficult to remove for maintenance.
