thermally efficient windows and doors

Our aluminium windows and doors are engineered with advanced thermal break technology to deliver outstanding energy efficiency and year-round comfort. By reducing heat transfer, they help keep your home warmer in winter and cooler in summer, making them an excellent long-term investment. Discover how low U-values and high-performance aluminium glazing can improve your home’s thermal performance while helping to reduce your energy bills.

what is a u-value?

You may have heard the term U-value before. Simply put, this measures how well a building component measures heat transfer. The lower the U-value, the slower or more difficult it is for heat to pass through the window or door. All elements of the window or door can be assessed, including the glass, frame, panel and more to ensure maximum energy efficiency.

U-values are measured in W/m2K. We work alongside reputable manufacturers who provide certifiable U-values you can trust. Our thermally efficient aluminium windows and doors are designed to meet and exceed modern building regulations.

THERMAL BENEFITS OF ALUMINIUM

THERMAL BENEFITS OF ALUMINIUM
THERMAL BREAK TECHNOLOGY

Thermal breaks prevent heat from flowing through the material and help provide a lower U-value and improved energy efficiency.

DOUBLE, OR TRIPLE GLAZED UNITS

Double or triple glazing will improve aluminium’s thermal benefits. In addition, quality glazing offers soundproofing and security benefits that are well worth the upgrade. Upgrade to aluminium double glazing today for the best thermal performance and lower your energy bills instantly.

THERMAL STABILITY

With thermal breaks and a multi-chamber core, our aluminium is much more thermally stable than other competitor products.

REDUCED HEAT TRANSFER

Our aluminium windows and doors’ multi-chamber cores reduce heat transfer in the winter but keep you cool and comfortable in the summer.

Doesn’t aluminium lose heat quickly?

Aluminium is a highly conductive metal; however, with modern thermal break technology and our quality systems, you won’t notice a difference between this and any other material. 

How long does aluminium last?

Aluminium windows and doors can last up to 30-40 years, making them a cost-effective solution in the long run over less durable materials like uPVC.

Do aluminium windows get condensation?

Quality double and triple glazing is best to avoid condensation buildup in any window. Contact us to discuss options for your home.
