System 25Hi+ Sliding / Lift And Slide Door - Thermally Enhanced

A thermally enhanced, twin or triple track lift and slide door system finished with a polyester powder coating.

Features and benefits:

• 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 106 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.
• With suitable glazing, doors can contribute to meeting the requirements of Building Regulations for conservation of heat and power.
• The doors provide Class IV weathertightness as defined by BS 6375-1:
• Air permeability: 600 Pa.
• Watertightness: 600 Pa.
• Wind resistance: 2400 Pa.
• 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.
• 25Hi+ lift and slide doors have been tested in line with PAS24 security standards and are certified by a UKAS accredited certification body.
• Aluminium sections are polyester powder coated to BS EN 12206, with the option of different interior and exterior colours. Consult Metal Technology for availability of colours and to obtain samples.
• Doors can accommodate a range of insulating glass units and can be glazed in the factory or on site. Doors are dry glazed using ‘snap-in’ extruded aluminium beads with colour coded, co-extruded, PVC nitrile, captive ‘E’ gaskets externally and ‘wedge’ gaskets internally.
• Each door leaf shall be fitted with an approved single lever locking handle.
• The sliding door set is fitted with Metal Technology’s standard locking system. The lock contains a security cylinder and associated euro cylinder guard both protected by Metal Technology’s security escutcheon.
