Impact of Foam Insulation on Global Warming!!

 

Generally, it is accepted that using more insulation will not only help you save more energy but is also better for the environment (i.e. reduce global warming).

 

 

However, in a recent article presented in the Environmental Building News, it was determined that not all insulation products provide the same net benefit to our environment.

Specifically, it was found that spray polyurethane foam, manufactured with a commonly used hydrofluorocarbon blowing agent, provided a marginal net benefit to the environment over its service life due to the fact that it requires a tremendous amount of energy to produce and that it gradually releases its blowing agent which in itself is an extremely potent greenhouse gas. 

 

 Conversely, it was also shown that the use of Cellulose Fibre Insulation (such as Therm-O-Light and Therm-O-Spray) provides the greatest net benefit to our environment.

 

 

What does this mean and how will this affect your decision? Well, if you are considering insulating with a closed cell spray foam (i.e. 2.0lb foam) which claims R-Factors in excess of 6.0 per inch, then you are more than likely considering a product which will provide a limited net benefit to our environment. If this is a concern, then you should consider insulating your attics and walls with our cellulose fibre products – Therm-O-Light and Therm-O-Spray Insulation.
