Warmcel Recycled Paper Insulation
by Dominic Muren, Philadelphia, USA on 04.25.05
Believe it or not, Excel Building Solution's Warmcel insulation is made from 100% waste recycled newsprint. But even more exciting is that it's been successfully installed in more than 1 million homes in the UK alone! With this excellent track record, and a thermal conductivity of just 0.036 W/mK, it's a great alternative to blown fiberglass or bat insulation. It can be layered into walls being built, or blown into attic spaces and already sheetrocked walls for extra protection from the cold. Excel also offers soundproofing material made from the same stuff. Definitely worth a look if you're considering an addition in the future. :: Warmcel insulation by Excel
This has been used for a while, and there have been some concerns about settling, the safety of the fire retardant and the chemicals in the inks that are still there in the recycled newsprint. If they have beaten those problems, or if this is different from what I have known as cellulose insulation (also made from recycled newspaper)then go for it!
They should provide the same type of packaging that standard insulation is found in since there might be increased costs in the installation/spraying process.
God, another flashback to the 70s and 80s when I was doing construction work. Blowing cellulose insulation is a very meditative process. I also enjoyed the process myself.
