Aluminium Casement Windows

Casement windows are a perfect choice for any type of building, and our aluminium windows are no exception. Fitted with double and triple glazing, all our products incorporate low emissivity featured glass units. DMWS Aluminium Casements are suitable for both replacing windows into existing buildings and installing them into new buildings. Aluminium is a strong and durable material, making our windows perfect for all environments. This strength also allows for more compact window designs – the material is durable, so it doesn’t need to be so reinforced as to become thick and unwieldy. As for the finish – you get to choose any colour you like.


With our profiles heights, designed for direct fix or frame fix, the system can meet all the building requirements for either domestic or commercial market place in London.

All of our products are fitted with double or triple glazing incorporating low emissivity featured glass units. They comply with current Government regulations regarding heat loss in your home as governed by FENSA. Optionally high security, easy-clean and full opening fire escape hinges are available as well as built-in restrictors ensuring your casement windows comply with the means of escape rule. Trickle vents can also be built into the outer frames. Full weather-stripping is standard and all relevant profiles have thermal barriers.

We use two system suppliers: Aluprof and Aliplast.
