Heritage (Stepped) Windows
This Aluminium window system is designed as a slim-line and thermally efficient replacement for Steel windows. As part of our Heritage Range it uses steel look-a-like profiles which will maintain the character and integrity of your period property. Finishing touches such as optional dummy butt hinges and traditional furniture complete the classic look. Our Heritage Windows are suitable for use in listed buildings, heritage and conservation areas.
Our Heritage Windows will be a huge improvement on your old steel windows. They use the latest ÔPolyamideÕ thermal break technology and have high security multi-point locking options, slim double glazed sealed units and are still a fraction of the cost of steel windows. Due to their high specification our Heritage Windows exceed the requirments for new build, replacement and refurbishment projects.
