Does the EPS provide support for a wood sill plate?
No, the EPS has no structural capacity to support any loads. Wood sill plates must achieve the required bearing from the concrete within the ICF. A wood plate that cantilevers 1⁄3 over the EPS and bears 2⁄3 on the concrete is allowable. This can be done with a minimum 2 x 6 plate. If a 2 x 4 plate is required, a taper top form should be used to extend the concrete under the plate.

Is installing ICFs a DIY project?
Fox Blocks recommends that all installers using Fox Blocks ICFs complete a Fox Blocks training program to ensure they have a better understanding of the basics. However, for first time installers, it is preferred that a Fox Blocks trained, experienced installer inspect the installation prior to placement of concrete and assist in the placement of the concrete, as they are familiar with working with concrete and can ensure the build is structurally sound and safe and the walls are consolidated properly, built straight and plumb.
Is a vapor barrier required on the inside face of an ICF wall?
No. The characteristics of an ICF wall with the mass concrete and the EPS insulation provide the required vapor permeance to meet building code requirements as a vapor barrier.

Effective Strategies to Insulate Block Walls
Improving the insulation of block walls significantly enhances energy efficiency, comfort, and durability in both residential and commercial spaces. Block walls, often made of concrete masonry units (CMUs), are sturdy but notoriously poor at retaining heat without proper insulation.
