Thermally efficient double glazing

Crittall Steel Framed Doors are ideally suited to the use of double glazing. Paired with high-performance glass and constructions that give excellent thermal efficiency, you can make significant savings on your heating bills and enhance the home’s atmosphere.

Let in more light

Crittall steel doors are a popular choice for bringing in more natural light into your home. The level of light let in depends on the finish you go for, with frosted glass letting in the most, polyester powder coating less, and oak wood veneers the least.  Choose polyester powder coating or timber veneer to match the interior finish of your home, or frosted glass if privacy is what you’re after. Being fitted with a secondary glazing layer can also help to lower heating costs as it will act as an extra insulation barrier.

Are Crittall doors expensive?
Crittall steel doors are custom made to order and available in a wide range of colours, styles, and finishes, ranging from plain steel to powder coated recesses. As a consequence, they are priced accordingly but for better value quality and longevity, particularly when compared with UPVC alternatives.
Are Crittall doors secure?
Crittall doors are designed with high security in mind, as well as beautiful design. It is very difficult to attack a Crittall door using tools that can be used on a normal door.

In the unlikely event that a burglar attacks an exterior door, the frame will be better protected than most other forms of door frame due to its tubular construction (other types of door frame just have 2 thin sheets of steel on each side).

Will Crittall doors rust?
Crittall steel doors are unaffected by rust and corrosion as they are 100% protected by an external coating of polyester powder, which is also environmentally friendly.
Can I get the original Crittall doors restored?
Yes. So long as the doors have not been refurbished in any way and fit within our guidelines, we are happy to take on a restoration of your Crittall Doors.

There is an element of risk when restoring old doors, but they will always look original as we will use factory methods, materials, and techniques, so long as applicable.
