Benefits of Double-Glazed Sash Windows

Double-Glazed Sash Window Benefits

We first started creating double-glazed sash windows in London way back in 1993, so we consider ourselves the “go-to” local experts 🙂 .We manufacture double-glazed sash windows of the highest quality, combining expert craftsmanship and the best materials.

What is double glazing?

Double glazed windows consist of two window panes, separated by a space that acts as a vacuum and which can be filled with gases such as argon or krypton to ensure better insulation and protection. Double glazing is highly efficient and very effective in reducing heat loss from homes.

Reduce Energy Consumption

Double glazing is such a great way to insulate your home, so it can dramatically reduce your energy bill, especially over the winter period. With less need to “put the heating on”, you will be reducing your energy usage, saving on monthly heating bills, plus you’re helping the environment.

Less Condensation

Condensation in Winter can be a real problem, especially in older homes. It can create mould and rot in timber window frames, plus it’s extremely unhealthy for you. Damp can affect your home’s air quality dramatically. Double glazing helps to minimise condensation by keeping the inner pane of the window warmer, and being protected from the cold outside it reduces the moisture created internally

Noise Reduction

Noise pollution negatively affects our health. So by reducing noise pollution in your home, you can have a better, less stressed, quality of life. Double glazing can reduce outside noise by up to 60% which is a huge reduction in day to day external unwanted noise.

More Secure

Double glazing is more secure than single glazed windows because they’re harder to break. By installing double glazing, you increase your home’s security as it’s more difficult for intruders to break in via, especially with laminated or toughened glass.

Add Value

Double glazing is a good way to increase the resale value of your property. All buyers will want to buy an efficiently insulated home, so installing double glazing is a must. Newly installed double glazed windows are energy efficient, secure and need very little maintenance and look smart too.
