Steel Look Internal Doors and Screens

Steel Look internal doors and screens create a stylish interior inside the home, complementing the exterior steel look windows and doors . Minimalist, slimline and distinctive, there’s a range of Crittall style internal doors and aluminium steel look internal screens. Everything you need to know about steel-look internal doors and screens and aluminium Crittall style room dividers.

Steel look internal doors and screens explained

Only genuine steel products such as Crittall® Windows, or other steel brands provide the best sightlines and true steel look. The aluminium versions of Crittall style room dividers or doors take inspiration from steel.

Steel always provides slimmer lines, but aluminium comes close. As well as this, other distinctive styling hues from the original products include the grid-like appearance, consistent lines, optional deep bottom rails and the thicker plate or panel behind any handles.

It’s also worth knowing many of the products in aluminium markets as interior system are actually external-grade products. Only Aluco Aluminium provides a dedicated interior system. It’s different from steel but highly effective.

If you’re choosing exterior systems it’s likely you’ll get double glazing and thermally insulated profiles – two elements you don’t need inside but perfectly acceptable nonetheless.

You’ll also find the same sightlines with the exterior-use models but there’s some excellent customisation available from specialists giving the right functionality, look and feel.

It’s also worth remembering with the exterior systems that you’ll quite likely get the same locks used on exterior doors such as multi-point locks. Again it’s not required as many internal doors only have a basic latching system, but many customers are happy with this arrangement.

Therefore, if your property has a requirement for fire-rated doors and you want the steel look, only certified products from specialist installers are suitable. You can find out more about this style of glazing, also has fire protection.

The choices are either steel with a fire-rating or steel-clad aluminium, also having the appropriate certification. Always seek professional advice.
