Steel Doors
Proven in use since 1979, in locations ranging from prestige city centres to rural hillsides exposed to the worst of the weather, Original Steel doors are truly outstanding.
Local authorities, housing associations, national major house builders and regional developers have all chosen to combine the visual appeal of traditional panelled doors with the energy saving, easy care characteristics that make Original Steel doors such high performers. They meet the exacting standards of newly built homes and provide an aesthetically acceptable means of improving the thermal performance of entry systems in older properties.
Original Steel doors offer a long lasting, low maintenance solution to the bowing, cracking, splitting and warping problems inherent in some solid timber doors. To ensure maximum effectiveness with minimum site labour, Original Steel doors can be supplied as complete doorsets comprising doors pre-hung in frames fitted with weathersealing components, or frames can be supplied in advance of doors to suit the build programme.
Original Steel Door Specifications
Door Construction
The Original Steel door is robustly constructed from two 24 gauge galvanised steel surfaces permanently bonded to a perimeter sub-frame of timber or synthetic stiles and rails, and filled with an insulating polyurethane core. The rigid polyurethane foam core is CFC and HCFC free, has an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of less than five. The steel skins have smooth external and internal faces.
Thermal Performance
Original Steel doors have a U value through the door of 0.55W/m2K, equivalent to approximately four solid timber doors. U values of doorsets for use in building regulation calculations are available from our Technical Department.
Sound Insulation
The Original Steel half glazed door has been tested by A.I.R.O (Acoustical Investigation and Research Organisation) and is capable of achieving an average sound reduction index (100-3150Hz) of 29 db.
Fire Resistance
Certain door styles are available as FD30, FD30S and Secured by Design accredited.
