Windows and doors from Sovereign Windows & Doors deliver superior strength characteristics when compared to other traditional materials.
Conductivity: Fibreglass combines strength with low levels of conductivity without adding thermal breaks. It is 250 times less conductive than aluminium.
Thermal expansion - “glass on glass” effect: With more than 60% glass content, the frame expanse and contracts almost identically with the pane of glass, thereby lowering stress significantly on the window or door and providing longer life and comfort.
Low maintenance: Fibreglass is a stable material and provides a suitable base for a full range of finishes, ensuring a durable window or door.
Environmentally friendly: Fibreglass composites feature a low embodied energy of the frame (low energy consumption in profile production) when compared to other common profile materials.
Non-corroding: Good performance even in the toughest condition.
