Icynene's LD-R-50 Insulation
Icynene LD-R-50 renewable-based foam insulation and air barrier
You've heard of its spray foam, and here's the next generation: Icynene's LD-R-50 is a renewable-based foam insulation and air barrier that is made using castor oil and offers numerous environmental benefits. A big plus is that castor oil has been used in place of a portion of the petroleum-based polyol, so three cheers for green attributes! For FREE information, visit http://pb.hotims.com/23726-341
