Prime SF

Prime SF (Support Frame) provides an adjustable layered interface between any backing wall and the Prime Rainscreen system.Prime-SF

Designed by CA Building Products and manufactured in-house Prime SF (Support Frame) is incorporated into all of the Prime Rainscreen systems. The frame can easily accommodate simple projections of 100mm to 300mm, with deeper projections available on request.

The ventilation void can be maintained to meet the recommendations from CWCT. This is achieved through the adjustment in length on the main bracket.

Depending on the access available on site, CA Building Products can assist the project’s critical path by supplying the support frame in both part assembled and stick format. All holes and slots will be pre-punched during manufacture to allow for greater efficiency.

Prime SF is made up of five basic components; main bracket, mullion or transom profile, sleeve connection for transom profile and fixing which is stainless steel, self drilling and self tapping. Prime II, Prime III and Prime V will require transom elements; this will also apply to Prime VII in some applications.

Prime SF is fabricated from aluminium. It sits in the void behind the Prime Rainscreen where the risk of corrosion is greatly reduced.

Prime II


Prime II is a traditional through-fix rainscreen panel system. The panels could simply be sheets of aluminium which are either anodised or powder coated.  Alternatively, the panels can be made up of a number of materials bonded together to form a composite material. These include ACM (Aluminium Composite Material), copper, plywood and steel. A key […]

Prime III


Prime III is a recessed fixed panel system offering visual depth for the building facade with the fixings hidden in the recess where the panels meet.   In order to obtain a clean design all of the recesses in the joint are developed so that the colour continues into the space between the panels. To […]

Prime V


Prime V has evolved from the PlanoWall Rainscreen system with enhancements made to ensure the CWCT testing criteria was met.   Like the PlanoWall system before it Prime V is based on a system of cassette panels which interlock on the top edge, concealing the panel fixings.  With Prime V the spanning capacity has also […]

Prime VII


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 […]
