Aluminium Windows.

Thermal Performance
Metal Technology's range, in conjunction with the correct glass specification, is designed to aid compliance with the latest thermal requirements of the 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.

Construction
Frame members are mitre cut at 45 degree, 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.

Finishes
The range of sections can be provided in either of the following ranges of finishes:

Anodised to BS 1615 or BS 3987 or BS EN 12373-1
