Home Innovation Research Labs Releases New “How To” Resources on Constructing Closed Crawlspaces

Closed crawlspaces, also called unvented, conditioned, or sealed crawlspaces, are dry, energy-efficient, functional, and practical options for single-family new construction, but they are a relatively new construction practice. To help residential builders more readily incorporate closed crawlspaces into their homes, Home Innovation Research Labs in partnership with the Southern Forest Products Association created a new bundle of educational materials specifically designed for builders and trades. The resources include a downloadable TechSpec and a four-part instructional video series – all are available online at no cost.

The first new resource is a TechSpec, “Closed Crawlspaces: Making the Transition,” designed to be an easy-to-read summary of the technology that addresses its benefits and key steps when transitioning from more traditional slab-on-grade or conventional vented crawlspace construction, or improving existing closed crawlspace design and construction practices. 

As highlighted in the TechSpec, benefits of a closed crawlspace include:

In addition to discussing the benefits, the “Making the Transition” TechSpec addresses code considerations, best practices, foundation walls, height and access, wood floor framing, moisture management, air sealing, insulation, and mechanical systems. The information presented is consistent with the provisions of the 2012 International Residential Code (IRC), and is focused on warm and mixed-humid climate regions in the southeast (Climate Zones 3A and 4A).

Beyond the summary information in the TechSpec, this educational resource bundle also includes a series of four instructional videos online that walk builders through the various stages of closed crawlspace construction and address specific hot spots in greater detail.  The four videos are:
