What is Proteus SR?

Proteus SR is our A1 or A2 fire rated rainscreen system that is available in a multitude of materials and finishes, including Powder Coated Aluminium, Pre Coated Aluminium, Anodised Aluminium, Stainless Steel and Weathering Steel.

The versatility of the Proteus SR rainscreen system allows the material thickness to be from 1.5mm to 5.0mm. Designers have the freedom using the Proteus SR system to lay panels in vertical, horizontal or a combination of both orientations. Standard 20mm vertical and horizontal joints provide a clean and effortless sightline to your facade.

The panels fix to a carrier rail with hooks at engineered centres. The hooks bolt into predesigned ports within the vertical rails rather than using self-drilling fixings, which offer maximum site adjustability and construction tolerance.

Vertical rails connect to support brackets engineered to a depth specific to your project with accompanying thermal isolator pads, allowing the system to be connected to all types of primary structures, including blockwork, precast concrete, timber frame, SIPS panels, SFS and insulated steel panels.

Secondary horizontal rails may be required, subject to the project’s framing system. This flexibility assists in reducing installation periods and offers maximum flexibility for new build, refurbishment and cladding remediation projects.
