Secondary Glazing
Secondary Glazing
Secondary glazing helps lock in more heat, reduce draughts and block outside noise from getting into your home. Perfect for listed buildings and period properties, it fits behind your existing windows to provide support and insulation.
With a choice of sliding or hinged opening configurations to match your existing windows, they are easily paired with a variety of window styles. Increase privacy or add protection from the sun with a variety of obscure glass options.

Our modern uPVC windows are energy efficient, with A-rated double glazing as standard. This helps your home feel comfortable all year round. Our uPVC frames can be upgraded to triple glazing to achieve the highest energy efficiency rating of A++, helping to reduce your energy bills.
Our uPVC Casement windows, uPVC Flush Casement, Elite Sliding Sash and Tilt & Turn windows are accredited by Secured by Design – a police initiative which aims to 'design out' crime. Our uPVC window frames have multipoint locking and design features to prevent glass removal from the outside.
uPVC is our most durable window material and carries a 10-year frame guarantee. Anglian White Knight uPVC casement windows hold the BBA accreditation, meaning they can last over 35 years.
We create, or extrude, our own uPVC window frames for our stormproof casement and tilt & turn windows at our Norwich factory. Making our own uPVC frames means we have complete control over their quality from start to finish.
