Glass Options
Glazing Types: Dual & Triple Glazed
All Sun products use dual glazed insulated glass as standard. This is composed of 2 pieces of glass with a 1/2" hermetically sealed airspace between them. Our insulated glass units are configured from a selection of low-emissivity glass with coatings that are designed for the variety of climates within our region.
Triple glazing is available on casement, fixed lite, and door products.
