Keeping our tootsies pampered during midnight trips to the bathroom is a job any carpet can handle. But clean the air of all that icky stuff floating around that we know is there but glad we can’t see? According to Dutch carpet manufacturer Desso, their new carpet line AirMaster can greatly reduce the concentration of that microscopic particulate matter to improve indoor air quality eight times better than hardwood floors. Tall claim, but they have several independent studies backing it up.
After five years of internal and third-party testing, Boral USA today announced the introduction of TruExterior Trim, an exterior trim material made with a blend of bio-based polymers and coal combustion product materials.

K-tect Sustainable Building Systems makes a wall system that the company calls the “newest generation of structural insulated panels.” Although not a sandwich panel, the system is kind of like rSTUD but different and more comprehensive.

Once again, there is discussion in the U.S. Green Building Council (“USGBC”) to allow other wood certifying organizations to have a place within the LEED guidelines for green construction. The new Pilot Credit 43 [PDF] for certified products would allow several wood certifications — e.g., Forest Stewardship Council, Sustainable Forestry Initiative, American Tree Farm — to contribute to a point under the trial credit.

The Cradle to Cradle bulbs — 40W, 60W, and 75W equivalents — have a self-cooling design that maximizes brightness and requires fewer LEDs.
