Important Update on Sprayfoam Insulation -- It Just gets even better!
The February 1, 2009 edition of Environmental Building News reports that Icynene will be introducing a new product with a planned minimum seven percent rapidly renewable content to its line.
This will be called Icynene LD-R-50, and will contain a polyol derived from the castor plant, which has a two annual growing cycles and can thrive on limited land resources. This now means that like the BioBased product that my earlier blog entry mentioned, Icynene will now have a renewable resource containing product that will qualify for LEED credit MR 6 -- rapidly renewable materials, as well as the other EA prerequisite and one credit in the energy area, for a total of two credits and one LEED prerequisite.
In addition, Icynene LD-R-50 will have a slightly higher R-value of 3.7 vs. 3.6 per inch, will be water-blown, contain no HFCs, will function as an air barrier and the cost will comparable to that of the petroleum-based Icynene product. For more information and updates, visit the Icynene site.
