Astroglaze are aesthetically designed glass rooflights, with high insulation values and offer simple on-site installation. They are designed to sit over builders timber kerbs and can be made to order to custom sizes in either single piece units or large multi-section units. Standard glazing is supplied clear, with a sandblasted border around the perimeter of the unit. This can be tailored to suit your individual kerb width – creating a smart appearance when viewed from either below or above.
