Steel frame deserves a helping hand

Rainscreen cladding on steel frame – simplifying construction

rainscreen cladding on steel frameWhen it comes to rainscreen cladding on steel frame, most cladding materials will likely have a rainscreen 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 rainscreen cladding on 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 rainscreen cladding system, we recommend the use of ‘helping hand’ brackets for all applications involving steel frame.

The Prowall rainscreen 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 manufactures 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.
