Original (heritage style) aluminium steel alternative windows from The Knight Collection.

Original Aluminium steel alternative windows

We have developed a range of steel alternative aluminium windows within our Knight Collection window range to meet the needs of those looking for an authentic looking steel alternative window without all of the problems associated with traditional steel windows such as single glazing, rust and draughts etc. Our steel alternative windows range closely replicate the look and slim sightlines of original steel windows whilst giving you enhanced thermal efficiency, improved security and all at a fraction of the cost.

Our range of steel alternative windows is available in a range of styles to suite a large range of property types. Steel windows are typically found on properties built around the 1930's and are often essential to the look and charm of a property. When replacing steel windows it is often essential to select a window that is sympathetic to the look of the original windows and our range of JKG windows do just that whilst vastly improving the energy efficiency over the original steel window. Our steel alternative windows have also been approved for use in listed buildings and conservation areas.
