White tripled glazed window

Energy-saving double glazing

Expertly crafted, our double-glazed windows and doors effectively work to keep your home at a comfortable temperature year-round whilst helping to save you money on your energy bills. Our double glazing consists of two panes of glass filled with argon gas which creates an effective thermal barrier between the inside and outside of your home. This results in U-values as low as 0.8W/m2K.

An extra layer of protection

Not only does double glazing improve the overall performance of your home but it also enhances your home’s security. The extra layer of glass makes it extremely tough for unwanted visitors to gain access to your home. As standard, our windows and doors come fully equipped with multipoint locking systems and quality hardware, so you can enjoy complete peace of mind that you and your loved ones are protected from any unwanted visitors.

Better noise reduction

As well as being incredibly efficient and secure, our high quality double-glazed windows and doors also offer fantastic acoustic insulation. It works to help block out external noise by the two panes of glass and the gas between them being able to absorb sound vibrations and dampen the transmission of sound, resulting in a quieter and more peaceful environment.
