Crittall Steel Doors

When it comes to large steel screens, John Knight Glass ensure you can achieve the authentic industrial look, popular with both interior designers and architects the Steel Screens are used both internally and externally. Internally a Steel Screen can act as a great design feature whilst doubling up as a sound barrier creating separation of space within modern open-plan living spaces and commercial spaces such as office blocks.

There are two main door types that we find our customers are looking for, this includes the traditional steel doors found on heritage properties such as steel french doors and the large steel screens that have grown in popularity recently with those building and renovating properties.

For owners of historic and heritage buildings looking for a replacement for their original Steel Doors, there are two clear options including our very own range of steel alternative aluminium windows from The Knight Collection. If you are living in a conservation area you may be required to fit steel windows however in some areas aluminium windows that closely replicate steel are permitted. The benefits of steel are the authenticity of certain features such as the slim frame profile and glazing beads. Choosing an aluminium steel alternative has the benefit of improved energy efficiency whilst still retaining many of the features of steel doors.

If you are looking for replacement windows for your Art Deco property, historic stone building or just looking for something a little different we can help you decide on the best solution when choosing steel windows.

Although very similar in design and manufacturing to your original Steel doors, modern Steel doors have certain enhancements over the originals. All Steel frames are now hot dip galvanised before painting for enhanced durability, Krypton-filled double glazing can be supplied for added energy efficiency and enhanced locking mechanisms for improved security.

Here are John Knight Glass we have several Steel products on display to demonstrate these stunning doors and we have the experience working with the product to help you when it comes to decision time and installation.
