Alitherm Heritage windows have been a popular choice for commercial properties for many years.  These windows were originally made from iron then later steel windows were created.  After this, galvanised steel became used in the windows.  In recent times, however, businesses and homes have come to realise there is an even newer option for these windows – aluminium Alitherm Heritage windows.

Here at Fortress Group, we offer to replace windows made with steel and other metals with aluminium Alitherm Heritage windows.  Aluminium is more cost effective than steel and also takes less maintenance – there’s no need to paint it or to coat it to prevent rust or corrosion as aluminium doesn’t suffer from either of these problems.

As well as replacing Alitherm Heritage windows with new aluminium versions, we can also replace other types of windows with this tough, durable material.  If you have timber, hardwood, oak or stone surrounds, aluminium windows are a perfect solution.  They can come in a variety of different colours and finishes to match in with other parts of the house and offer an excellent U-value – meaning they can help save you money on your utility bills by making the property more energy efficient.

We also offer aluminium windows in a variety of styles so if you have a style you like and want to see about having it added to your home, we are happy to chat about it.
