ICF Help & Advice

Our insulated concrete formwork help & advice centre has been created as a reference and information hub for designing and building ICF structures in general, and Polarwall in particular.

ICF Claddings & Finishes

Timber cladding the popular option for cutting an ICF wall, both horizontally and vertically. when we talk of timber we are also including the cement fibre boards such as those from James Hardy.   

the boards cannot be fastened direct to the ICF structure I need to be fastened 2 timber batten’s to create a small air gap behind the cladding. On most ICF systems vertical timber cladding requires both a batten and the counter batten.  On Polarwall we have devised a method of using vertical timber cladding with only a single layer of timber battens.  

the same method of using timber battens for fastening a timber cladding is used when using either slate tiles or cedar shingles.

The various sections above cover the main topics for ICF construction both above and below ground. 

Do not use this as an alternative to what your chosen manufacturer recommends.  We can do things with Polarwall that ICF blocks can’t do and there may some things that you do with other ICFs that Polarwall can’t do. For example our instructions on vibrating the concrete may not be wise on some EPS block systems. 

We want to add to and develop this section, so we welcome all your questions, suggestions for topics and feedback.  If you want to go deeper into a topic please let us know.  This advice hub does not replace our training (or any other companies training) and you still need to avail yourself of our FREE training course.
