Southern Pine Council Teams With Habitat for Humanity to Promote Raised Floors

Tuesday, September 1st, 2009

As part of its effort to promote raised-floor construction, The Southern Pine Council recently partnered with Habitat for Humanity to build two pairs of homes–each containing one raised-floor and one non-raised-floor unit–to document the differences between the two techniques.

The homes in each pair, which were built side by side in Mobile, Ala., and across the street from each other in Vero Beach, Fla., were identical except for foundation type: raised floor vs. slab. A study is being conducted to evaluate the construction costs of the two methods, to measure whether or not users save money on utilities with either method, and to analyze other variances in living factors.

Southern Pine representative Kim Drew told Hanley Wood editors that raised-floor construction is a better choice for these areas, in particular, because the method helps reduce the potential for flood damage. Homeowners also thought the raised homes looked better, she added.

Arch Wood Protection Introduces New Flame-Retardant Product

Arch Wood Protection recently introduced FlameDXX fire-retardant OSB.

The Class A fire retardant product is factory-coated with a proprietary treatment that allows it to be used as a noncombustible material in many applications, such as for roof and wall sheathing, ceilings, soffits, and subfloors. According to the company, it corrodes metal no more than uncoated OSB.

FlameDXX complements Arch’s more expensive flame-retardant plywood treatment, Dricon, representative Julie Chaplan told Hanley Wood editors. The product can also save builders money because they will not have to install sprinklers to meet code, she added.

Arch is targeting the product for the commercial and multifamily markets, along with single-family homes in regions with stricter fire codes, such as California.–Victoria Markovitz

Shake Test Shows Promise of Wood-Framed Mid-Rises in Earthquake Zones

A team of scientists, including representatives from manufacturer Simpson Strong-Tie and Colorado State University, performed the world’s largest earthquake shake table test in Japan last week, creating the equivalent of a 7.5-magnitude earthquake on a seven-story condo tower made up of 23 one- and two-bedroom units. According to a statement, early results showed little damage to the structure, a promising result that has building engineers confident in the future possibilities for mid-rise wood-framed structures, which typically are limited to five stories in earthquake-prone areas.

“The testing thus far has shown that performance-based design for light-frame wood structures works,” said Steve Pryor, structural engineer for Strong-Tie, in a statement. “This will allow the engineering and building community to provide safer, better performing buildings in the most cost-effective manner.”

The NEESWood Capstone tests are part of a four-year, $1.4 million grant from the National Science Foundation.
