Why choose steel?

There are many reasons to choose original steel for your windows. Primarily, because it is 100% recyclable. In fact, all the steel (and glass) we use for our windows, doors and partitions comes from recycled material. We know you care about the planet and so do we.

The second reason is, as mentioned previously, it’s versatility. Because steel is such a strong material it can be used to create a large variety of windows and doors. Some of these include, but are not limited to:

  • Pivot windows and Pivot doors

Steel Window & Door FAQ

What are Original Steel windows and doors?

Steel windows and doors are often called Crittall windows or Crittall style windows . This is because in the early 20th century steel windows were popularised and manufactured by Crittall Ltd. Today there are not many companies in the UK who can now fit similar looking steel windows and doors. Our windows and doors have been inspired by the traditional design that Crittall Ltd made popular. For inspiration click HERE.

Are steel windows energy efficient?

Due to modern glazing technologies steel windows and doors comply with current building regulations for thermal performance. This means your doors will keep you cool in the summer and warm in the winter.

Are original black steel doors fire rated?

Our specification of internal black steel doors have been tested to withstand 30 minutes of fire. Currently the options available are for single doors, double doors and fixed partitions.

Do steel doors rust?

New technologies give steel windows and doors anti corrosive properties. The frames are galvanised which coats the frames in a protective zinc coating. They are then powder coated which further protects the metal. In fact, there are many steel windows in use today that were constructed earlier than 1950. This truly is a testament to their durability.

Are steel doors secure/safe?

All our external steel windows/doors are glazed using toughened glass. As standard our doors are fitted with British Standard locks and shoot bolts to ensure your safety.

Are steel windows single or double glazed?

Steel windows can be double glazed and even triple glazed. Our steel profiles can accommodate glazed units up to 30mm thick. Resulting in very energy efficient windows and doors.

What is Crittall style?

Crittall style refers to windows and doors that have a square pane configuration using horizontal and vertical glazing bars. This style was popularised by Crittall Ltd in the early 20th century. View our inspiration gallery for more examples.

What is thermally broken steel?

A thermal break or thermally broken refers to a high performance insulator that separates the internal side of your window or door to the external facing side. This insulator creates a barrier and stops the cold outside temperatures from creeping into your home through the metal.

Is there a benefit to Original steel windows and doors?

The main attraction to using steel is its strength. This allows for large windows and doors to be made without the bulky frames, typical of timber or aluminium windows. Steel also holds a different texture when left bare or powder coated.
