At Sovereign, we use the finest uPVC and aluminium profiles for the windows within our double glazing range. These profiles offer high levels of thermal efficiency, offering an environmentally friendly way of saving the Bishop’s Stortford homeowner money on their energy bills. Most designs are thermally broken or multi-chambered, working alongside the glazing panes to trap in pockets of warm air. This will create a comfortable temperature within your home throughout the year, even in the cold winter months.

The windows we have in our double glazing range suit every Bishop’s Stortford home. We currently install casement, flush sash, sliding sash, tilt and turn, styleline and aluminium windows. Our product range suits both modern and traditional properties alike and can be customised in a range of colour and woodgrain foils to match your style.
