The basic suite accommodates 70, 80, 100 or 120mm thick panels to accommodate all expected options and applications. The system is capable of accommodating the Metal Technology 4-20, 5-20, 7-20, 4-35Hi, 5-35Hi systems and their Hi+ variations. Various other profiles can be designed and incorporated allowing architects to achieve flexible designs. The windows are glazed internally or externally to accommodate a range of glazing options. Fixed panes may also be externally glazed with the addition of a liner bar. As with all Metal Technology systems, the Panel Adaptor System is manufactured to exacting standards enabling economy to be combined with strength to give many years of aesthetic, trouble-free operation.
Performance Overview
Weather Performance
The Panel Adaptor system is designed to provide the following levels of performance:
Air permeability – BS 6375 : Pt. 1 test pressure 600 Pa
Water tightness – BS 6375 : Pt. 1 test pressure 600 Pa
Wind resistance – BS 6375 : Pt. 1 test pressure 2400 Pa
These levels of performance should be sufficient for any locations within the UK and Ireland. However should higher levels of performance be required for any reason, Metal Technology’s advice should be sought.
Size Limitation
The size limits for the windows inserted into the panel adaptor system should be in accordance with the relevant system manual. In addition to the above fabricators shall give consideration to the maximum sizes
that they are able to safely handle without damaging the sealed corners.
Materials
Aluminum profiles are extruded from aluminium alloy 6060T6, T5 or T4 complying with the recommendations of BS EN 12020-2/BS EN 755-Parts 1 to 9. Polyamide thermal breaks are produced from glass reinforced nylon sections designed to withstand temperatures in excess of 200°C, allowing the sections to be powder coated after thermal breaking.
Construction
Cill/jamb members are mitre cut at 45°. Corners are screw fixed and reinforced with extruded aluminum cleats and corner braces. Head/jambs are mechanically fixed with angle cleats and joint blocks. All frame joints are sealed during construction against entry of water. For full details of the 4-20, 5-20, 7-20, 4-35 and 5-35 window systems, refer to the relevant system manual.
Finishes
The range of sections can be provided in either of the following range of finishes:
1. Anodised to BS EN 12373-1 or BS 3987
2. Powder organic coated to BS EN 12206-1
The System 24 window can accommodate a different colour/finish internally to that used externally.

Thermal Performance
Metal Technology System 24, in conjunction with the correct glass specification is designed to comply with the latest thermal requirements of the current building regulations (see separate document on compliance with thermal regulations).
The thermal performance of System 24 is further enhanced by the introduction of specially designed thermal foams, resulting in the system being known as System 24 Hi+. These foams reduce radiation heat loss across the air cavity in the window profiles to provide additional thermal enhancement. Where a less onerous thermal specification is required the foams may be omitted, resulting in the system being referred to as System 24.
