4. Benefits of UPVC Double Glazed Windows

Energy Efficiency

The amount of heat loss is greatly reduced with the use of UPVC double glazed windows. This means that the boiler is not on for as long, resulting in lower bills. A-rated windows can have a significant impact on the amount of money spent on bills for families living in Croydon, especially with the increasing prices of fuel.

Noise Reduction

The space between the two panes of glass acts as a sound barrier. Families living near roads or train tracks can have the noise of the outside world reduced by as much as 35 decibels with the use of double glazing.

Enhanced Security

Double glazed windows have advanced greatly from the old single-glazed windows that were so easy for burglars to break in. Modern UPVC double glazed windows have multi-point locking systems and can also have toughened glass. These windows are often sufficient for insurance purposes, giving families peace of mind.

Low Maintenance & Durability

Unlike wooden frames, UPVC windows do not need painting or any special treatment. They can simply be wiped clean. With a 10-year guarantee on all of our installations, Glitz Windows allows families to enjoy the benefits of double glazing for years.
