Aluminium Window's Contribution to Energy Conservation
Energy conservation involves reducing wasteful energy use by improving efficiency (achieving the same output with less energy) or adopting sustainable behaviours (e.g., minimising energy-intensive activities). Efficient energy use offers significant benefits, such as lowering greenhouse gas emissions, shrinking carbon footprints, and saving money, water, and resources.
In homes and buildings, around 30% of heat escapes through windows, with poor insulation leading to higher energy bills and unnecessary consumption. Upgrading to double-glazed windows with aluminium frames with daylight glazing can improve a property’s energy efficiency by up to 75%, significantly reducing heat loss.
Enhanced Insulation with Double Glazing
Double-glazed aluminium windows dramatically improve insulation, retaining warmth in winter and blocking excess heat in summer. Since nearly a third of a building’s heat loss occurs through windows, proper glazing helps maintain indoor temperatures, cutting energy costs.
Why Aluminium Frames?
Aluminium offers superior precision in construction, eliminating gaps or weak joints that allow heat transfer. Combined with daylight glazing—which optimizes natural light while enhancing thermal performance—these windows maximize energy savings.
Stronger material supports more glass
Generally, the more glass, the better the thermal efficiency. Aluminium is such a strong material it allows glass to take centre stage with a slimmer window frame design. It can also support more robust glazing, whether you opt for double or daylight triple glazed windows, as the frame is strong enough to support the glass unit inside completely, working with it seamlessly to seal the cold air out and the warm air in.
Quality and Sustainability
Our aluminium windows are manufactured in the UK using advanced techniques, ensuring top-tier insulation and an A-rated energy efficiency performance. Local production also minimises transport emissions, supporting environmental sustainability.
Window Energy Ratings (WERs)
All windows are graded for energy efficiency, similar to household appliances. While the legal minimum is WER C, high-performance aluminium windows with daylight glazing often exceed this, delivering superior energy savings.
Choosing the Right Solution
To select the most efficient windows, always check the WER rating and consult an aluminium glazing specialist. Modern daylight glazing solutions not only conserve energy but also enhance natural lighting, reducing reliance on artificial sources.
Recyclability
Aluminium is 100% recyclable without losing its properties. Using recycled aluminium in window production consumes only 5% of the energy used in primary production, making aluminium windows a highly sustainable choice.
Long lasting efficiency benefits
Boasting a lifespan of 30-40 years, aluminium windows and doors are durable and robust, and retain their insulating properties. Aluminium is also 100% recyclable at the end of its life and is endlessly recyclable. In fact, according to the Aluminium Association, nearly 75% of all aluminium ever produced is still in use today.
