Product Description
DOWNER FRAMING SECRET FIX CLADDING SUBFRAME SYSTEM
DCS004 SYSTEM OVERVIEW
Downer Framing secret fix rainscreen cladding framing system, DCS004, is designed to provide a mechanical secret fix support to most rainscreen cladding panels using the principle of a ventilated façade.
DCS004 MSF can be installed onto our DCS031 HELPING HAND®, DCS041 Floor to Floor or DCS021 Omega & Zed system offering design freedom to suit project specific thermal and structural demands and variation in cavity depths.
CAVITY RANGE
An increase of 26mm would need to be added to framing support system cavity to allow for Downer DCS004 Panel Hangers and Horizontal Carrier Rail.
DESIGN CONSIDERATIONS
The ends of any DCS004 Horizontal Carrier Rail unsupported cantilever should be ≤150mm or as dictated by project specific static calculations.
At building corner locations, HCR cantilever can be increased up to max. 300mm and must be strapped to adjacent HCR using an “L” rail angle such as DCS031 60×40 L rail.
DCS004 HCR must not span across and be fixed to the other side of a building movement joint.
Adjustable panel hangers allow for a 10mm adjustment. A lift of 17.5mm will allow the panel hanger to clear the horizontal rail. Therefore, we advise a minimum of 25mm clearance gap for ease of installation.
A minimum vertical distance of 91mm from fixings between vertically spaced brackets is required for installation of the panel.
If adjustable bolt raises the panel over the allowable limit, remove panel and adjust HCR to suit.
Downer Framing's DCS004 secret fix rainscreen cladding subframe system can be specified by NBS Source.
