Thermally broken commercial door systems.
Construction:
Profiles are extruded from aluminium alloy (6060 T6, T5 or T4 to BS EN 12020-2/ BS 755-9) and with polyamide thermal break sections manufactured from glass reinforced nylon sections capable of withstanding temperatures in excess of 200°C. Outer frame sections are a minimum of 50 mm deep incorporating two 20 mm polyamide thermal break sections within the door profiles.
Joints in outer frame and vent members are formed with 45 degree mitres, reinforced with extruded aluminium cleats and stainless steel corner braces. Corner joints are secured by pneumatic crimping. Mullions and transoms are secured using stainless steel screws driven into integral screw ports within the sections: additional cruciform cleats are used where required. Joints are sealed using a small gap sealant.
Doors incorporate an internal pressure equalized drainage system with external ‘snap-on’ cover caps.
Performance:
With suitable glazing, doors can contribute to meeting the requirements of Building Regulations for conservation of heat and power. Consult Metal Technology for recommendations and details.
The doors provide Class IV weathertightness as defined by BS 6375-1:
Design wind pressure to be determined in accordance with BS 6399-2.
Fixing:
Lugs and/ or frame anchors used to secure windows to the building structure must accommodate predicted loads and deflection within design tolerances. Generally, fixings must be positioned 150 mm from each corner and each mullion/ transom, and at centres not exceeding 600 mm. Fixing lugs/ straps should be used only where they can be suitably concealed.
Secured by Design:
System 5-20TS doors have been tested in line with PAS24 security standards and are certified by a UKAS accredited certification body.
