West Leigh have revolutionised the construction industry by offering the most comprehensive line of fire-rated steel windows and doors. West Leigh's Fire-Rated Windows are put through rigorous testing.

The modern version of the steel window has the same classic appearance, but is more energy efficient and versatile than ever before. The look of these iconic, slim framed, vast expanses of glass make the windows a popular choice, and something that will last for several years to come.

Metal windows and doors made from Aluminium, steel or bronze are stronger because of their structural strength. However, the disadvantage of this feature is its mismanaged energy efficiency since metal conducts heat easily. This means on a hot day a solid metal frame will act like a radiator in your room, and likewise, on a cold day, you will be losing heat outdoors through your frames.

When you are looking at the metal window and door options you may see the term ‘thermally broken’ or ‘non-thermally broken’ throughout the information you are reading. If you are not experienced in selecting or specifying steel frames this may be a foreign phrase to you but it is one that is very important when choosing the steel window/door system.

Steel windows and doors have been in existence in their current form since the 1930’s, and a well manufactured window will last, easily, for 50 years or more. You are still able to find the traditional single glazed steel windows, commonly known within the industry as the SMW window. If you have existing steel windows and live in a listed property or conservation area these are the windows you will normally be required to replace your originals with.

West Leigh Ltd installed a range of W50 TB windows into 100 Union Street, London. This project reflects the steers from research on progressive workplace design.
