Why Choose Aluminium Windows

Aluminium windows offer plenty of benefits that make them a perfect option to consider when replacing your existing windows. Our aluminium windows are low maintenance and are not liable to rotting or warping in the elements making them a good choice for homeowners.

The slim profile design allows for maximum glass area letting in a large amount of natural light into your home and enhancing the aesthetic appeal.

By choosing aluminium windows, it is not just a choice for today, it is a long-term investment for your home as it offers sustainability, style and low maintenance.

Modern aluminium windows are thermally-broken using polyamide, an excellent insulator which helps to insulate windows against heat loss. The thermal conductivity of polyamide is 160 times better than steel, which for a typical terraced house would provide a saving of around £95 each year in fuel costs. In addition to these energy savings, the polyamide also raises the internal temperature of a house, helping to reduce the risk of condensation.

Our expert team at Park Lane can discuss with you the various options available and why you may wish to consider opting for aluminium over UPVC or Wooden framed windows.
