Why New Double-Glazed Windows are a Smart Investment

Double-Glazed Windows

Double-glazing is a popular home improvement. More than 90% of UK homes now have at least some double-glazed windows. It’s a relatively affordable upgrade that offers a lot of benefits, whether you plan to stay in the property or you are moving in the near future.

In this article, we will explore why investing in new windows is a wise decision.

Better Energy Efficiency

The UK government has set challenging targets to improve the energy efficiency of the country’s housing stock. It hopes to reduce energy demand by 15% by 2020. There has been a big push to encourage homeowners to install heat pump boilers, but anyone with older single-glazed windows or low-quality double-glazed windows will see an immediate benefit if they fit new, energy-efficient double-glazed windows.

Older windows typically have a 6mm gap between the panes of glass, whereas newer units have a larger 16mm gap, which is better at retaining heat inside the home. Swapping out old windows for new ones could see your home’s energy efficiency improve by as much as 25%.

Noise Reduction

Another advantage of investing in new windows is improved comfort and noise reduction. Older windows may not effectively block outside noises, leading to noise disturbances from traffic and reduced privacy. Newer windows are designed to provide better sound insulation, creating a quieter and more peaceful environment indoors. In addition, modern windows often come with features like UV protection, which helps to block harmful sun rays and protects your furniture, flooring, and upholstery from fading over time.

Better Security

Safety and security are also important considerations when it comes to windows. Outdated single-gazed windows may have weak frames or locks, making them vulnerable to break-ins – it’s really not hard to force open a window when there is only one locking point.

Newer double-glazed window models typically incorporate reinforced frames, advanced five-point locking mechanisms, and impact-resistant glass, providing enhanced security for your home. This added level of protection can bring peace of mind, especially for homeowners concerned about their family’s safety. You may even find that your home insurance offers a discount if you have double-glazed windows with locks.

Increase the Value of Your Home

Replacing old windows makes a home more attractive to potential buyers. New windows can significantly enhance the kerb appeal of a property, making it look better in property listings. Window replacements have a high return on investment, adding as much as 10% to the value of the property. New windows also help to sell a home because it is one less task for buyers to worry about. This means that not only will you enjoy the benefits of new windows while living in your home, but you can also expect a higher resale value if you decide to sell in the future.

Aesthetic Improvement

Older windows are often very unattractive. Not only can they look shabby and may have peeling paint if they are made from timber, but older double-glazed windows often lose their seal, which causes the glass units to mist up. In addition, white UPVC windows can be affected by sunlight and turn yellow, which is not an issue with newer windows.

If you’re looking to improve the look of your home, windows are a good investment. There are some very attractive designs to choose from and newer windows come in different colours these days, ranging from grey, black, and green to cream and timber effect. No matter what style of house you have, chances are there is a window design that will enhance it.

How to Choose a Window Installer

Choosing a reputable and reliable windows installer or company that offers home improvement services is essential to ensure a smooth and successful window replacement or installation project. With so many options out there, it can be hard to make the right choice. Here are the key factors to consider.

Experience and Reputation

Start by researching the experience and reputation of potential installers. Look for companies that have been in the industry for several years and have a track record of delivering quality workmanship. Check online reviews on Google and social media. A well-established local installer with positive feedback is a safe bet.


A professional company will be responsive, prompt, and courteous in their interactions. They should be willing to answer your questions, provide detailed information about the installation process, and offer recommendations based on your specific needs. Good communication is key to a successful collaboration.

Product Knowledge and Options

Look for an installer who is knowledgeable about different window types, materials, and energy efficiency options. They should be able to guide you through the various choices available and help you select windows that meet your requirements and budget.

Warranty and Guarantees

Bigger companies offer warranties on their products, but some smaller firms do too. Ask about the warranties and guarantees offered by the installer. A warranty ensures that you are protected against any defects or issues that may arise post-installation. Be sure to read and understand the warranty terms and conditions before making a final decision. Check the windows are covered by the FENSA guarantee, as you’ll need this certificate when you come to sell the property.

Price and Quotes

While cost shouldn’t be the sole determining factor, it is important to obtain multiple quotes from different installers. This allows you to compare prices and ensure you are getting a fair deal. Beware of significantly low-priced offers, as they may indicate subpar quality or hidden costs. Look for a balance between affordability and quality workmanship.

Check Certifications and Affiliations

Certain certifications and affiliations can indicate an installer’s commitment to professionalism and expertise. For example, certifications from organisations like the Glass and Glazing Federation (GGF) or the British Fenestration Rating Council (BFRC) demonstrate their dedication to meeting industry standards. Affiliations with trade associations can also be a positive sign.

Timeline and Availability

Discuss the timeline and availability with the potential installers. Ensure they can accommodate your preferred installation dates and complete the project within a reasonable timeframe.

A well-chosen installer will ensure a successful window installation that enhances the functionality, aesthetics, and energy efficiency of your home.

New windows offer numerous advantages and are a smart investment for homeowners. So, if you’re considering home renovations or purchasing a new property, be sure to prioritise new windows.
