Nudura forms stay in place to provide insulation value (R24) and vapour protection. Ties are built into each block, reducing labour costs significantly over plywood. Plywood forms require all ties to be installed on the jobsite, and require stripping once the concrete has been poured. Nudura forms fold flat to reduce shipping costs and are lightweight (15 pounds for 12 ft2).

The Nudura block has rigid plastic ties that run the full height of each block and located 8" on centre. It is easy to attached drywall to the ties using 1-1/4" drywal screws. The pullout strength of a drywall screw is 185 pounds, so there is plenty of holding capacity.

Horizontal rebar is slipped into the block every 18" on centre. Special rebar tabs make positioning a breeze. Vertical rebar is installed from the top, weaving between the horizontals at each block level.

We recommend using the Nudura Peel & Stick membrane. For details, click HERE. The advantage of the Peel & Stick is that it acts as a slip plane, allowing the soil to slide down the foundation.

We recommend attaching the windows to the inside face of the opening. You will need to contact your window manufacturer to ensure he supplies flanges designed for this detail. We do not recommend attaching to the outside face of the ICF as this exposes the window to the ravages of inclement weather.

Testing of moisture ingress of different wall/window assemblies shows that side mounted windows perform significantly better than surface mounted.

Nudura blocks are 18" high and can be cut in half to product a 9" height. There is also the Optimizer block which is 12" high (or 6" when cut in half). Finally there is the 3" height adjuster. For a calculator showing how to achieve any wall height, click HERE.

We have a list of 58 installers in the Greater Vancouver area. We will send your project details to these installers so that they can quote on your project.

There are many ways of aligning the foundation wall with the framing above. Please contact us for details on your project.

The area between the ground and the start of the framing is a very important to protect as the ICF is soft and can be damaged. We recommend attaching a strip of 1/4" Hardiboard using stainless steel screws. The area can also be parged with waterproof stucco over a fiberglass mesh.

This can be achieved in a number of ways. The floor system can be constructed on top of the ICF wall, or it can be attached to the inside face of the ICF wall. Click HERE for details on the different options.

We recommend yes. However, according to the 2020 revision to the BC Code, there is no need for the rainscreen and the cladding can be attached directly to the ICF. For our full discussion, click HERE.

No. The Nudura block qualifies as a vapour barrier. For details, click HERE.

The Nudura block has rigid plastic ties that run the full height of each block. As they are located 8" on centre, it is easy to attach the siding to the ties. The pullout strength of a #8 screw is 185 pounds, so there is plenty of holding capacity.
