If you want the benefits of double glazing, but replacing your windows isn’t an option, secondary double glazing is the perfect solution. Our secondary double glazing is a great choice because it:
- Fits seamlessly over your existing windows
- Helps to retain warmth
- Improves sound insulation
- Removes draughts from your existing windows
Secondary double-glazed windows are a great choice if you live in a listed building or conservation area where replacing windows is more difficult. They're available in a number of styles and are designed to match your existing windows, whatever the shape or size. They also offer very slim, unobtrusive sight lines on the inside and are virtually invisible on the outside.
Vertical sliding units are perfect if your home has original sliding sash windows, and they can tilt for easy cleaning. If you have horizontally-opening windows, we can install matching sliding units for between two to five casements. Or, if your home has single opening casement windows, we can make secondary double glazing to match.
Whatever the style, our secondary double-glazed windows are inconspicuous and blend in seamlessly with your home. As with every Anglian window, our secondary double glazing is bespoke and individually made by our team of skilled craftspeople to ensure you get exactly what you want.
