Double Glazing

Installing double-glazed windows in a property improves the aesthetics and makes the home more energy efficient. Double glazing is also an investment in security and the value of your home.

Double glazing adds about 10% to the value of your home. Replacing old windows with double glazing can also save between £65-£110 per year on energy bills. Modern double-glazed windows also come with upgraded locks and security features.

Double glazing is one of the most popular home improvements for all these reasons. Homeowners in Cornwall have trusted Best Glaze for over 20 years to upgrade their windows, doors, and conservatories to attractive, energy efficient double glazing.

  • Timber windows are environmentally friendly and can last for a lifetime.

Aluminium windows come in a range of colours and styles to help you achieve that contemporary look for your home. High-quality aluminium windows & doors will last a lifetime.

You should consider aluminium windows because:

  • Aluminium windows have a lifespan of up to 45 years and will not rust.
  • We can use sturdy frames for large windows to let in more light without adding frames.
  • High-quality frames come in a wide range of colours and can create a modern look.

Double glazing increases the value of your home by up to 10%. Double-glazed windows also reduce the noise from a busy road or traffic. Double glazing also reduces your energy bills by £65-£110 per year.

Warm, sunny summers mean homes in the South West get plenty of sun. Double glazing can help you harness the power of the sun to warm up your living spaces in the morning. Easy-opening modern mechanisms open easily to let in the late afternoon breezes.

Winter chills, wintry winds, and rain showers are no problem with double-glazed windows to keep out the cold. The added insulation and thermal protection will keep your home warm in the colder months.

Double-glazed windows provide much better sound reduction than a window with a single pane of glass. Increasing traffic and more neighbours mean your peace and quiet could be shrinking. Double glazing a window can bring some of that tranquility back to your home.

A window with double glazing contains a layer of gas between each window pane. This combination of extra glass and the gas layer create a much more effective sound barrier than a single window pane.

Double glazing and replacement windows add value to your home – as much as 10%. Buyers know they will not need to replace the windows, so the home’s value goes up. The added kerb appeal can also make it easier to attract buyers.

Double glazing, especially with uPVC windows, will eventually pay for itself due to lower energy bills. However, the increase in property value may mean an immediate return on investment.

Secondary Glazing

Secondary glazing is another perfect solution for homeowners living in conservation areas or in listed buildings. We are one of the top quality double glazing companies offering the installation of secondary glazing. This improvement satisfies listed building regulations and can convert each window by adding an extra layer of noise and temperature insulation.

What Is Secondary Glazing?

Secondary glazing allows homeowners to keep the original window in place. An aluminium glazing unit fits inside your home, creating a second window indoors, thus the name double glazing. This is an attractive way to upgrade a listed house without changing its external appearance.
