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

Over the years brick slips have proved to be a popular choice for the cladding of ICF walls.  The brick slip finish gives the attractive look and durability of brick,  but without taking up too much space in the thickness of the overall wall.  Typically the slips are attached to the permanent insulating form work boards, either with an epoxy based adhesive or a cementitious adhesive. 

There are some manufacturers of brick slips, but most product still seems to come from cutting the faces from a  traditional brick. 

Some of our clients have opted to make their own brick slips from recycled  and reclaimed brick stock.    

Typically most brick slips are made at around 15 millimetres thick.  

Proper set out is required when starting to place the brick slips and a consistent spacing both horizontally and vertically between the slips makes for an attractive cladding finish.


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.
