Powershield Steel Doors The Challenge was to provide a high performance security door offering, tailor-made to meet each individual customer’s needs, with sustainability embedded from concept through to completion. Powershield’s latest generation of steel doors are designed to support architects, specifiers and contractors, working on a wide range of projects from commercial office space and healthcare applications to data protection units and pharmaceutical facilities. Doors are manufactured with 48 percent recycled steel and are almost fully recyclable.Powershield high performance acoustic doors from ASSA ABLOY Security Doors are manufactured from steel, which provides a greater mass than other raw materials and therefore considerably limits the transmission of sound. Extensive research has been conducted to create a combination of materials that produce improvements in insulation and stiffness. This, in turn, helps to limit the vibrations of the door, producing improved acoustics and sound control.A complete range of high performance doors, bespoke to the customer’s requirements. The use of recycled material and the recyclability of the doors means virtually nothing will go to landfill, but instead will be reused at end of life.The research focus on stiffness and insulation has resulted in excellent thermal properties yielding a low U-value. This makes Powershield’s steel doors highly energy efficient, ensuring thermal comfort while also reducing the end user’s operating costs and environmental impact.Delivering sound reduction of up to 45dB, ASSA ABLOY Security Doors’ latest generation of steel doors are proven to effectively manage sound transmission. They have been used at the Cork School of Music, where the combination of acoustic properties and attractive aesthetics, has resulted in a functional and modern facility.
