SAS Prowall Cladding: Steel frame deserves a helping hand
Rainscreen cladding on steel frame – simplifying construction
When it comes to rain-screen cladding on steel frame, most cladding materials will likely have a rain-screen support system or façade mounting system specified. These are commonly known as ‘helping hands’.
Steel frame deserves a ‘helping hand’
When render facades are specified for a steel frame it is often a different story – our Technical Team have seen all types of systems cobbled together that only complicate the build process. However, in many cases with a rendered rain-screen cladding on a steel frame, a ‘helping hands’ system can be used to simplify the construction process and allow for easier interfaces between cladding finishes.It can be surprising how often you come across a steel frame development that has render specified and the building fabrics in-between are either over-engineered or complicated, not allowing for an easy transition between finishes. With ProWall, our rendered rain-screen cladding system, we recommend the use of ‘helping hand’ brackets for all applications involving steel frames.
The Prowall rain-screen system
The ProWall system in conjunction with ‘helping hands’ brackets has many benefits, including:
Allowing for the use of incredibly thermally efficient foil-faced phenolic or Polyisocyanurate insulation
Placing the cavity on the face of the insulation, as opposed to an EWI rail system that has the cavity behind the insulation
Allowing for one style of support system for all the different cladding finishes
Increased impact resistance compared to traditionally used EWI systems
Simple and fast installation
Adjustable void depths
30 or 60-year BBA certification
10-year guarantee.
The ProWall system can be used with all leading bracket manufacturers such as Nvelope, Hilti Eurofox, Amari Allface and others. ProWall uses our advanced render carrier board and cavity barrier fire seals, and is finished with highly water-resistant silicone render – take a look at the finishes and colours here.For more information or if you have any questions on the use of ProWall with ‘helping hands’, please contact our technical team on 01647 24620.
