The Ultimate Guide to Energy-Efficient Windows

October 2, 2024 Steve Sherbourne

When it comes to home improvement, energy-efficient windows are one of the best investments you can make. Not only do they help reduce your carbon footprint, but they can also save you money on your energy bills and increase the comfort of your home. At Windrush Doors and Windows, we specialise in installing top-quality, energy-efficient windows designed to meet the unique needs of UK homeowners.

In this guide, we’ll explore what makes windows energy-efficient, the benefits of installing them, and how you can choose the best options for your home.

What Makes a Window Energy-Efficient?

Energy-efficient windows are designed to minimise heat loss and improve insulation, ensuring your home stays warm in the winter and cool in the summer. Several factors contribute to the energy efficiency of a window, including:

Double or Triple Glazing

Glazing refers to the layers of glass in a window. Double-glazed windows have two panes of glass with a space between them, while triple glazing has three panes. The space between the panes is often filled with an insulating gas, such as argon, which reduces the transfer of heat. This layer of insulation prevents heat from escaping in the winter and keeps warm air out during the summer, enhancing your home’s energy efficiency.

Low-E Glass

Low-E, or low-emissivity, glass is treated with a special coating that reflects heat back into the room. This helps maintain a consistent indoor temperature without overworking your heating or cooling system. Low-E glass also allows natural light to enter your home while blocking harmful UV rays, preventing furniture and carpets from fading over time.

Window Frames

The material used for the window frame plays a crucial role in its energy efficiency. Aluminium frames, such as those offered by Windrush, are durable, lightweight, and have excellent insulating properties. Modern aluminium windows are designed with thermal breaks—an insulating barrier between the inside and outside of the frame—which helps reduce heat transfer.

Weather Seals

A high-quality weather seal around the window frame prevents drafts and moisture from entering your home. This airtight seal helps maintain indoor temperatures and prevents energy loss, making your home more efficient.

Benefits of Energy-Efficient Windows

Energy-efficient windows offer several advantages beyond just improving insulation. Here are some of the key benefits:

  • Lower Energy Bills: By reducing heat loss and improving insulation, energy-efficient windows can significantly lower your heating and cooling costs. In fact, upgrading from single-pane to double- or triple-glazed windows can reduce energy consumption by up to 20%, leading to noticeable savings on your energy bills.
  • Enhanced Comfort: With energy-efficient windows, your home’s interior temperature remains more consistent. You’ll experience fewer cold spots near windows in the winter, and rooms will stay cooler during the summer. This creates a more comfortable living environment all year round.
  • Noise Reduction: Double and triple glazing provides excellent sound insulation, making your home quieter and more peaceful. If you live in a busy area, energy-efficient windows can help block out unwanted noise, creating a calmer indoor space.
  • Reduced Condensation: Energy-efficient windows are less likely to experience condensation build-up, especially in the winter. The insulating layers prevent the interior glass surface from becoming too cold, reducing the chances of moisture forming. This not only improves the view but also protects the window frames from potential damage caused by excess moisture.
  • Increased Property Value: Installing energy-efficient windows is a smart investment for your home. Not only do they improve the aesthetics and comfort of your property, but they can also increase its value. Potential buyers are often attracted to homes with modern, energy-efficient features, knowing they’ll save on energy bills in the long run.

How to Choose the Right Energy-Efficient Windows

Selecting the right windows for your home depends on various factors, including your budget, climate, and personal preferences. Here are some things to consider when making your choice:

Glazing Options

If you live in an area with extreme weather conditions, you may want to consider triple glazing for maximum insulation. For more moderate climates, double glazing is usually sufficient and more cost-effective.

Frame Material

Aluminium is an excellent choice for energy-efficient windows due to its strength and insulation properties. It’s also low-maintenance and available in a variety of finishes to match your home’s design.

Window Style

The design and functionality of your windows can impact their energy efficiency. Fixed windows tend to be more efficient than operable ones since they are sealed around the edges. However, if you prefer windows that open, consider casement windows, which provide a tighter seal than traditional sliding windows.

Professional Installation

Even the best energy-efficient windows won’t perform well if they aren’t installed correctly. At Windrush Doors and Windows, we ensure that all windows are professionally installed to maximise their energy-saving potential and provide a perfect fit.

This June Windrush installed 39 Pvcu windows to our student accommodation block at Rewley Abbey Court. The work required them to install the windows while residents were in occupation, some with young children. Windrush carried out a full risk and method statement and appraisal to carry out the works in a safe manner with multi-occupation to consider. Full scaffolding and access booms were used with everything being alarmed and fenced off with appropriate signage in place. The Windrush team involved had all the necessary accreditation holding CSCS cards, asbestos awareness trained, CRB checked etc. The windows were as per our requested specification with Windrush being the most competitive out of the competition. The College are very pleased with all aspects of the work carried out and will be using Windrush on our future projects.

Windrush have installed new pvcu patio doors in the residents homes on site. The window installers being friendly and polite and having a nice demeanour and getting on well with the residents. The work was carried out in a professional manor with their work being clean and tidy all with an insurance baked guarantee. I would have no hesitation in recommending them to others.

I would just like to say that I was very impressed by the two young men who came to do the windows yesterday, they were very efficient, had impeccable manners and they cleared up after themselves which was a joy.

Windrush serviced two Velux windows and re-glazed with new sealed units, re-glazed a bedroom window with three sealed units, and re-glazed a conservatory upgrading sealed units to “Low E Argon” gas and thermal bar

During the School holidays the Windrush team carried out window adaption works for the School. Windrush installed remote window winding equipment to our high level windows that have been a health and safety issue with pupils and staff standing on chairs to open. I can recommend Windrush for their professional approach, competitive pricing and ability to accommodate our requirements during a busy time with many other trades on site. They were willing to change their work schedule to accommodate changing circumstances on site.

Windrush recently attended our Academy and replaced damaged window hinges and handles with great success. The Windrush Team who carried the work out were very professional with the work being carried out during normal School hours. The Health and Safety aspect being covered with the adoption of measures from their risk assessment and method statement being carried out.
