Fully CWCT Tested

Wintech Engineering carried out full testing of the Rainscreen System with CWCT (Centre for Window and Cladding Technology) on behalf of CA Group.

PRIME-II-1020104

Responsible designers are seeking confirmation of the technical performance of rainscreen offerings.

The Prime range was extensively tested in accordance with the CWCT Standard for Systemised Building Envelopes, a leading information provider and trainer in the field of building envelopes and glazing.

Wintech Engineering Ltd is an independent UKAS accredited testing laboratory specialising in delivering a comprehensive range of testing services throughout the building, construction and allied industries worldwide.

TS011---9th-Sept-2013-021Wintech is able to undertake a vast range of Building Envelope Performance Tests including weather performance, air leakage, impact, spray bar, and hose testing. Testing is performed at their state-of-the-art facility, based in Telford, Shropshire or onsite at the required project location.

The performance criteria for CA Group’s Prime Rainscreen included water penetration and both wind and impact resistance.

The products available in the Prime Rainscreen portfolio benefit from the extensive knowledge and experience of the CA Building products team and include some outstanding features:

  • Use of flat panels for ease of transportation to allow for improved efficiency
  • Fixed holes and hooks pre-punched in our factory which aid assembly on site
  • Panels can be easily removed and replaced with minimal disruption to the end user
  • Larger panels can be re- enforced with stiffeners to meet the performance criteria of CWCT
  • Manufacturing excellence
  • Computer controlled manufacturing
  • Access to skilled tradesman
  • Quality control at all stages

At CA Group we are committed to working with our clients and their designers to develop systems which meet specific requirements. Our belief is that a systematic approach will provide a long- term cost effective solution.

Prime VII comprises of a support structure which is typically Prime SF which uses brackets to fix the vertical mullion hook carriage to the frame. A project specific delivery can be developed by determining the design and wind performance requirements, this allows us to calculate the hook centres and support pins. Prime VII allows a […]
