Why steel windows and doors?
Crisp, narrow profiles and simple joinery allow for large expanses of glass with minimal sight lines.

How strong are steel windows and why choose them?
Crittall Windows steel sections have a tensile strength of 355-510N/mm² and a yield strength of 230-260N/mm². The inherent strength and versatility of steel, offers architects and designers the freedom to create bold architectural statements without compromise.

What is the expected life of the hot-dipped galvanising?
This galvanising process will last for 60+ years.

What is the expected life of the Duralife polyester powder-coating?
With regular washing in soapy water, the powder-coating will last for 20+ years – on the assumption that windows would be painted every 4-5 years, this equates to 4-5 painting cycles.

How do Crittall Windows contribute to the highest possible energy rating for your building?
While the U value of the steel frames is rated at 5.8 W/m²K, the narrow profile ensures that all Crittall steel window products meet the centre of pane U-Value of 1.2 W/m²K.

What is the fire resistance of steel windows?
The Crittall Corporate 2000 range has a fire rating of ½ an hour, and with specified metal screens, will comply with a high Bush Fire Attack Level (BAL).
