Steel Replacement Windows and Doors

Steel-look windows made by Everglade Windows in Middlesex

Steel replacement windows are the aluminium alternative for the replacement of old metal casements or Crittall® windows. These windows, doors and screens provide contemporary or heritage glazing in new extensions and elsewhere in the home.

Importantly, while aluminium versions of steel-look windows offer credible alternatives to steel, only the genuine steel windows products are best. Steel windows are the genuine article also with the best sightlines and aesthetics. However, the incredible quality and craftsmanship of steel windows also come at a higher price.

For homeowners replacing old steel windows with a similar alternative, aluminium systems provide an alternative solution. There’s now a diverse range of products and suppliers.

For the trade, there are many knowledgeable fabricators of steel-look aluminium windows and doors.

Over the last thirty years, PVCu windows replaced many old steel windows. These addressed the draughts, poor weather performance and energy inefficiency of old metal windows.

However, they’ve not retained the character and appeal of older houses where the metal windows are a feature. Today this trend has shifted to dedicated systems designed to offer 21st-century window technology while retaining traditional looks.

Information about steel-look and steel-replacement windows

Windows, screens, residential doors, single and double doors with sidelights. These are the best-designed steel-look products. Bifolding doors from some systems also offer a very credible look. Sliding doors less so, although there are products, well-customised and giving a great look. The trade can contact us for details of some of the best fabricators and suppliers of steel-replacement systems. Homeowners can also get in touch with us for further information and where to buy.

How these products come together and the types of profiles used are key to getting the best in appearance and a credible steel look.

Some providers simply put glazing bars over the glass for the multiple panel effect. This is the most basic type of steel look windows. More credible products from systems such as Reynaers, Smart Systems and Aluk are best known. Then there are others such as Decalu aluminium system, come specifically designed as a steel-look product. Air MOD Series offers more versions than other systems.

Another consideration is are the glazing bar profiles. Not only must these products use the right size of the glazing bar. It’s crucial that sightlines run consistently across the entire product and especially when choosing doors with sidelights.

Deep bottom rails, putty line sightlines, the right window and door handles and the backplate feature on residential doors. These are the key features that a good supplier of steel-replacement windows should address in the products they supply.
