What are the best windows to keep heat in?

Improving your home’s energy efficiency is a major priority for many UK homeowners. With heating bills at an all-time high, people are looking for the best ways to improve their home’s heat retention capacity to save money and create a warmer living area. One of the best ways to do this is with energy-efficient windows.

Improving Energy Efficiency with Replacement Windows

According to UK government statistics, 18% of a property’s heat is lost through its windows. This is a huge proportion of overall heat loss in a building. It is also something that can easily be reduced. With high-performance double glazing or triple glazing, you can significantly reduce heat transfer through your windows and improve your home’s overall energy efficiency.

Replacement windows are a great way of improving your home’s thermal performance. Modern double glazing fitted with low-emissivity glass panes is designed to regulate the sun’s rays. It does this by reducing harmful UV rays penetrating the building interior while at the same time helping to trap any warm air generated inside the home. This means that you won’t need to use your heating as often, helping you to save money on your energy bills.

Window types to boost your home’s thermal performance

At Albany Windows, we install a variety of window types. All our window styles are designed to meet current energy performance requirements and will have a significant role in improving your home’s energy efficiency. We offer our customers uPVC windows and aluminium windows, which can be fitted with double, triple, or secondary glazing.

Choosing the right type of glazing and frame materials plays an important role in improving insulation. Casement windows and sash windows are a popular choice for older homes, while modern double glazing with timber frames or wood frames can help retain the aesthetic of original windows. For those looking for better insulation, selecting a third pane of glass or inert gas-filled glazing, such as argon gas or krypton gas, can further reduce the transfer of heat.

Glass Options for Maximum Energy Efficiency

To ensure customers receive the most energy-efficient windows, we offer the latest window glass technology. Some of our high-performance glass options include:

• Planitherm Glass – Excellent solar control for better heat retention and reduced solar gain
• Acoustic Glass – Laminated glazing to reduce sound transmission
• Solar Control Glass – Regulates solar heat gain for a more comfortable home interior
• Anti-condensation Glass – Features a highly insulating coating to reduce condensation

Why Upgrade to Energy-Efficient Windows?

Replacing your windows is one of the most important factors in improving the energy efficiency of your home. Not only does it help reduce your carbon footprint, but it also provides an added benefit of improved security and reduced regular maintenance. Unlike single glazing or a single pane of glass, modern double glazing with thermal breaks and Energy Star-rated window glass ensures that your home stays warm while lowering energy bills.

In recent years, the demand for the most energy-efficient windows has increased, with many homeowners opting for triple glazing despite the additional cost per square foot. While timber frames and wood frames require regular maintenance, uPVC windows and aluminium frames provide a low-maintenance alternative with excellent insulation.

Which Windows Offer the Best Insulation for Homes?

Improving insulation with the right windows can make a substantial difference to your home’s energy efficiency. Choosing between double and triple glazing, low-emissivity glass, and insulated frames helps reduce heat loss, lower energy bills, and create a more comfortable indoor environment.

How do energy-efficient windows help reduce heating costs?

Energy-efficient windows reduce heat transfer, meaning less warmth escapes during winter and less heat enters in summer. This lowers the demand on your heating system, helping you cut down on energy bills. Features like low-emissivity glass, inert gas fillings, and multi-glazing provide better insulation.

What is the difference between double glazing and triple glazing?

Double glazing consists of two panes of glass with an insulating gas layer, while triple glazing adds a third pane for extra insulation. Triple glazing provides better heat retention, reduces noise more effectively, and minimises cold spots, though it comes at a higher cost.

Which window frame materials provide the best insulation?

uPVC and aluminium frames with thermal breaks are excellent for insulation. Timber frames also offer good thermal performance but require more maintenance. Modern frames are designed to prevent heat loss and improve overall energy efficiency.

What is low-emissivity (Low-E) glass, and how does it work?

Low-E glass has a special coating that reflects heat back into the room while allowing natural light in. This reduces heat loss in winter and minimises solar gain in summer, making it a key feature of energy-efficient windows.

Are energy-efficient windows worth the investment for older homes?

Yes, replacing single glazing in older homes with modern double or triple glazing significantly improves insulation and reduces draughts. Retrofitting with secondary glazing or using timber-look frames helps maintain the property’s aesthetic while enhancing efficiency.
