The research reported in this paper is aimed at increasing the understanding of the hygrothermal performance of interior basement insulation systems by a combination of field monitoring of four… Read More

This article briefly repeats some of the information in the other mold articles but also includes information on how to prevent mold in residential structures. Mold requires water. No water, no mold… Read More

Builders for many years have put mechanical equipment and ducts in non-living spaces such as crawlspaces and attics primarily to save valuable floor space. Be that as it may (there are lots of good… Read More

This is a concise overview of the principles and steps to follow when dealing with water from the foundation to the roof.

In climates where the average monthly temperature for the coldest month of the year goes below 45°F, the temperature of the slab perimeter may be below the dew point of interior air for a significant… Read More

Basements are part of a home, within the building boundary—despite repeated attempts over the years to disconnect them from the living space. Because of this, basements should be designed and… Read More

Keeping soil gas (radon, water vapor, herbicides, termiticides, methane, etc.) out of foundations cannot be done by building hole-free foundations because hole-free foundations cannot be built. Soil… Read More

Water managed foundation systems prevent the build-up of water against foundation walls, thereby eliminating hydrostatic pressure. No pressure, no force to push water through a hole.Groundwater… Read More

The purpose of this guide is to provide useful examples of high performance retrofit techniques for the building enclosure of wood frame residential construction in a cold and somewhat wet climate.… Read More

This guide provides code requirements for basement insulation and clarifies whether building code allows for leaving insulation exposed in the basement. The requirements are based on whether the… Read More
