Why Upgrade to Double Glazing?

Modern double glazing has come a long way from the products of 20 years ago. Today’s high-performance double glazed units feature warm-edge spacer bars, low-emissivity glass coatings, and inert gas filling between the panes — all of which dramatically reduce heat loss compared to older double glazing or single-glazed windows.

At Lancashire Window, we install A-rated double glazed windows in uPVC and aluminium frames across Burnley, Blackburn, and the whole of Lancashire. Every window we supply is manufactured to the latest British standards, and comes with a comprehensive guarantee for your complete peace of mind.

Frequently Asked Questions

According to the Energy Saving Trust, replacing single-glazed windows with A-rated double glazing can save a typical semi-detached home around £150–£200 per year on energy bills. Savings will vary depending on your home size and existing windows.
A warm-edge spacer bar separates the two panes of glass around the perimeter of a double glazed unit. Unlike aluminium spacers, warm-edge spacers are made from low-conductivity materials that reduce heat loss around the edges of the glass, improving the overall energy rating of the window.
Our double glazed windows are designed to last 30 years or more with normal care. The sealed unit itself carries a manufacturer’s guarantee, and the frames are guaranteed against defects in materials and workmanship.
In most cases, replacing windows with a like-for-like style does not require planning permission. However, if your home is in a conservation area or is a listed building, restrictions may apply. Our team can advise you during your free home survey.
