Assa Abloy UK's division Security Doors has installed Powershield steel doors at Terminal 2 of Heathrow Airport.
As part of Heathrow's £1bn expansion of Terminal 2, the company supplied high security Powershield fire and personnel doorsets.
Under the project, the company will provide acoustic, fire and security doors from the Powershield range, some of which feature special laminated facings and stainless steel kick plates for increased durability.
The acoustic doors, which can control unnecessary noise due to their special insulation, have been tested independently in accordance with BS EN ISO 140 pt 3 and calculated for sound reduction values under BS EN ISO 717-1 standards.
Assa Abloy Security Doors managing director Brian Sofley said: "Our steel doors are extremely durable and provide a high level of fire protection that could prevent the spread of fire and create maximum evacuation time for passangers and staff in the event of an emergency - an essential safety feature in busy transport hubs like airports."
Heathrow's head of design development Barry Weekes said: "As the UK's only hub airport, Heathrow required a high quality solution to meet our exacting security requirements.
"The superior strength, durability and security of all the steel doors supplied to this project, combined with their relatively low maintenance requirements makes them the ideal choice."
The terminal will also receive double and leaf and half door sets that will have an overlapping astragal detail for architectural appeal. Astragal will maintain fire integrity on double leaf steel doors.
