Steel Doors & Windows

Steel doors and windows have been favoured since the 1930s, for their strength, style and durability. Today, modern steel doors and steel windows also offer energy efficiency, security, and can be easily maintained.

Cotswold Casements offers a range of different metal doors and windows to suit every property. From the latest W30 windows, which offer the most up to date double glazing technology, to the traditionally made leaded light glazed windows, which look great on old stone and brick houses. We take great pride in our large range: even 300-year-old flat iron windows can be replaced!

For doors, we favour the industry-leading W20 steel doors. With the slimmest sightlines of any type of door, they will maximise the light within the room whilst offering the durability and strength of steel.

High Performance

W30 steel windows and W20 steel doors are designed for energy efficiency and offer the slimmest steel options currently on the market. The W30 and W20 steel windows and doors are also double weather-stripped and hot zinc thermal sprayed to prevent rusting.

  • Hot rolled steel section, keeping the slimmest sightlines possible
  • Hand fabricated in our factory in Moreton in Marsh
  • Frames protected using hot zinc thermal spray
  • Wide range of ironmongery available
  • Powder coated RAL colour of your choice
  • 18mm double glazed units with a krypton gas and low ‘e’ coating


Listed & Conservation

If your property is in a listed or conservation area, it can sometimes be confusing as to what you're allowed to change or how you can improve your property. At Cotswold Casements, we have a vast knowledge of listed and under-conservation properties, and we can help with the process, making everything a little easier when it comes to window replacement or refurbishment..

Of course, you always need to check with the Conservation Advisory Panel before making any changes to a listed building. However, you may be able to replace your existing windows with a slimline double glazed steel version.
