extruded polystyrene (XPS), or a cement-foam composite. By way of a variety of manufacturing methods and formulations, rigid foam insulation is typically produced by introducing a blowing agent into the manufacturing process, creating uniform air pockets throughout. This results in a lightweight foam material with superior thermal properties.

Extruded polystyrene (XPS) is a rigid foam board that can be placed on the inte-rior or exterior of foundations. Installation of XPS foundation insulation is simple, and no training or special techniques are neces-sary. However, for most interior foundation applications, XPS cannot be …

Extruded polystyrene (XPS) is resistant to degradation from the components of common soils and will retain its insulating performance characteristics even after prolonged exposure to moisture. Provides a weather resistant barrier (when joints are sealed) to enhance the building resistance to air and moisture penetration.

sections from the NAHB Model Green Home Building Guidelines where Owens Corning products—when properly installed and thoughtfully integrated into the design—can help builders meet their green building goals.

FOAMULAR 250 extruded polystyrene (XPS) rigid foam insulation contains hundreds of millions of densely packed closed cells to provide exceptional thermal performance. It's also virtually impervious to moisture, unlike other plastic foam insulation products, preventing loss of R-value due to moisture penetration.

2009年5月14日 · WOODBRIDGE, Va. - The Extruded Polystyrene Foam Association (XPSA), a trade association of the industry’s manufacturers, partnered with the NAHB Research Center to publish informative, online resources about extruded …

• FOAMULAR® XPS insulation is also the first insulation to be approved under the National Association of Home Builders (NAHB) Research Center Green Approved Products seal of approval. Approval indicates third-party documentation that a building product

As of April 2020, more than 216,000 homes have been NGBS Green certified. The 2020 edition is the fourth edition of the standard, which reflects significant changes based on evolving market conditions and feedback received over the past decade from those using the standard.

This guide is intended to simplify the design and construction of frost protected shallow foundations (FPSFs) and promote their widespread use. The underlying data was obtained from National Association of Home Builders (NAHB) members who provided demonstration sites for evaluation of the performance of FPSFs.

2010年8月19日 · XPS is used all the time under footings for unheated buildings with frost-protected shallow foundations. See Figure 7 (on page 17) in the NAHB Research Center publication, “Revised Builder’s Guide to Frost Protected Shallow Foundations” (http://www.toolbase.org/PDF/DesignGuides/revisedFPSFguide.pdf). Just be sure that you choose XPS with ...
