Foam sheathing is a very effective means of insulating the interior or exterior of foundation walls, preventing heat loss and lowering the risk of condensation issues. Use of foam sheathing on foundations for frost protection can save thousands of dollars in construction cost and energy bills.

This standard is a code referenced guide for designing and constructing cost-effective and energy-efficient foundations using foam plastic sheathing.
To assist U.S. home builders, remodelers and trade contractors in the design, construction, and code approval of frost protected shallow foundations.
This guide produced for the U.S. Dept. of Housing and Urban Development initiated modern recognition of frost-protected shallow foundations in the U.S. – ultimately resulting in building code acceptance and development of the ASCE 32 standard.
Provides information and construction details concerning thermal protection, subdrainage, waterproofing, vapor controls, structural requirements, radon control, and termite damage prevention when constructing or renovating residential or small commercial projects.
Field testing and report finding that houses and other structures may be built on shallow, slab-on-grade foundations in cold climates when properly insulated to protect against frost heave.
