T50 vented and drained cavity system

T50 cladding system

The PRIME.design T50 system consists of an aluminium ventilated rainscreen support structure for cladding products. The system installes over standard framing to NZS3604 requirements, and allows for concealed and mechanical fixing of a range of cladding products on a cavity with a width between 50 and 230 mm. T50 has been tested to NZS4284 and NZBC E2/VM1 using HPL (Trespa, as promoted by Decortech) or Kalsiclad HD+.

The typical hook (A) on the back of the vertical T50VR serves two purposes: it guards against water running around the vertical profile T50VR and it creates an easy, weathertight solution for the fixing of flashings onto the structure by means of the vertical clip T50CL.

The cladding products that can be fixed with the T50 system are

- Fibre cement sheets Equitone® and Kalsiclad® HD+ 
- HPL sheets Trespa® or similar
- Clay 
wall tiles Terreal® or similar
- Na
tural reconstituted stone sheets
- M
etallic sheets etc.

The following patterns with large-size façade panels are possible.

Engineered brackets allow for fixed and floating points to cater for expansion of rainscreen panels and thermal movement of aluminium profiles.

Fixing method: concealed fixing

PRIME.design uses BOSTIK Paneltack and SIKA Sikatack for the bonding of panels on aluminium structure. The glue system consists of four elements: primer for aluminium, primer for the back of the panel, double-sided adhesive tape and structural glue.

Fixing method: mechanical fixing

Sheets are fixed with aluminium rivets with diameter 4.8 mm, length of minimum 20mm and a head diameter of 16.0 mm. A customised aluminium ferule is used to avoid stress on the cladding sheet at the fixing point.
