Description

Metal Technology's System 4-20Hi+ offers the designer a wide and diverse range of profiles that provide structural integrity, weather performance, thermal enhancement and security. It is a highly cost-effective glazing solution complying with and in many cases exceeding current Building Regulations. The polyamide thermal break profiles have been specifically designed to minimize heat transfer across the window profiles. Thermal performance is further improved through the introduction of specially designed thermal gaskets and foam profiles. These reduce radiation heat loss across the air cavities within the window profiles to provide additional thermal enhancement.

Secured by Design:

All glazed curtain walling screens, windows, and doors within the ground floor and vulnerable areas are secure by design.

All systems installed are tested in line with PAS 24 security standards and certified by a UKAS accredited certification body.

Standard product features

Profiles:

Extruded aluminium alloy (6060 T6, T5 or T4 to BS EN 12020-2; BS 755-9; 2001).

Construction:

Frame members are mitre cut at 45°, corners are reinforced with extruded aluminium crimping cleats and corner braces, and a secure joint is formed by pneumatically crimping into the extruded crimping cleat. Mullion and transom bars are square cut shaped and fixed securely to the frame by means of stainless steel screws and fixing cleats. All frame joints are sealed during construction against entry of water using Metal Technology’s two-part adhesive. Metal Technology recommend that only A2 or A4 Austenitic (300 series/class 70) stainless steel fixing screws are used in the assembly of their products.

Sill Liners:

All windows incorporate a sill liner profile to accommodate made to measure bespoke push fit aluminium sill pressing.

Glazing:

Windows can accommodate a range of insulating glass units, and are dry glazed using ‘snap-in’ extruded aluminium beads with colour coded, co-extruded, PVC nitrile, captive ‘E’ gaskets externally and ‘wedge’ gaskets internally. Consult Metal Technology for recommendation and details.

Air tightness:

All windows have a continuous EPDM seal fitted to their perimeter.

Technical properties:

Air infiltration (to BS EN 1026): Class 4.

Watertightness (to BS EN 1027): Class E900.

Wind resistance (to BS EN 12211): E2400.

Ironmongery/ Accessories:

Opening vents are hung on a pair of friction hinges or butt hinges, sized to the manufacturer's recommendations, and are fitted with standard push-to-release, lockable, cockspur handles (CA12). Opening vents are fitted with friction restrictors to limit opening depth to 100 mm. Consult with Metal Technology for recommendations and details of additional ironmongery options.
