Exceptional Thermal Performance

Designed to improve your home’s performance, our double-glazed windows and doors exceed the minimum energy efficiency level for homes in the UK. Double glazing is proven to reduce the amount of heat escaping from your windows by 50%. It features two panes of glass filled with argon gas, which creates a highly effective thermal barrier between the inside and outside of your home. Achieving U-values of as low as 0.8 W/m²K, you can enjoy a more comfortable home whilst reducing your energy consumption. What’s more, our double-glazed solutions help to lower your energy bills.

An Extra Layer Of Protection

Not only does double glazing improve your home’s overall performance but it also improves your home’s security. Choosing to insert extra panes within your new replacement windows makes it tougher for unwanted visitors to break in. When combined with our multi-point locking systems and quality hardware, you can enjoy complete peace of mind knowing that you and your loved ones are protected from any intruders. You can be rest assured that you’re in safe and reliable hands with Double Glazing Essex.

Better noise reduction

Double glazing also helps to create a quiet and peaceful environment. This works by the two panes of glass and the gas between them being able to absorb the sound vibrations and dampen the transmission of sound. For homeowners who live near a busy road, school or airport you will appreciate the higher level of acoustic insulation that double glazing provides.
