The Ultimate Guide to Energy-efficient Windows and Doors

Keeping your home energy efficient doesn’t always require big changes. Small, everyday habits can make a real difference to comfort, heat retention, and overall energy use.

This short guide shares practical energy saving tips and advice, with a focus on how high performance windows and doors can help your home work more efficiently.

How can I improve energy efficiency at home right now?

One of the easiest ways to support energy efficiency is to make better use of what your home already offers. Letting natural sunlight in during the day helps warm rooms naturally, while closing curtains and blinds in the evening helps keep that warmth inside. Being mindful of ventilation and avoiding unnecessary heat loss also helps maintain a more stable indoor temperature.

These simple habits support efficient energy use and can reduce how hard your heating system needs to work.

How do windows and doors support energy saving?

Windows and doors help save energy by acting as a barrier between your home and the outdoors. Features such as double or triple glazing, insulated frames, and argon-filled sealed units slow the movement of heat, helping to keep warmth inside during winter and reduce heat entering the home in summer. This makes it easier to maintain a comfortable indoor temperature while using less energy.

Well-designed windows and doors also help prevent draughts through effective sealing, supporting lower energy bills and a reduced carbon footprint. Many homeowners also notice added benefits such as fewer cold spots, reduced condensation, and improved insulation from outside noise.

What type of window is most energy efficient?

Energy-efficient windows are designed to work as a complete system. Modern PVCu windows often use a multi-chambered frame design, creating multiple insulating layers that help limit heat transfer through the frame.

Glazing plays a key role too. High-quality double glazing can achieve strong energy performance, with standard U-values around 1.2 W/m²K. For those looking to maximise efficiency, triple glazing offers even better insulation and can achieve U-values as low as 0.83 W/m²K. As a simple guide, the lower the U-value, the more energy efficient the window.
