Spray foam insulation – Review preview
From an energy conservation perspective, a big energy problem with conventional homes is that their forced air duct systems are usually located in attics, which invariably turn out to be the hottest places. The result is that cool conditioned air traveling through the ducts gets reheated, and the air conditioners have to work much harder to deliver comfort.
The green solution to this problem is to include the attics into air-conditioned spaces. To achieve this, attics have to be properly air sealed and very well insulated. The product of first choice to achieve this is polyurethane spray foam insulation.
Polyurethane spray foam insulation comes in two main types, a lightweight open cell type and a heavier closed cell type. The latter not only expands and fills every nook and cranny of the attic, thereby creating an airtight insulation barrier, but it also provides a watertight shield against water intrusion.
The walls and floors of many green homes are also sealed with spray foam insulation in order to create a complete air tight envelope, or shell around the home.
Although being partly oil based, polyurethane spray foam has green credentials because it has an organic plant-based component as well, and because it is responsible for such a significant reduction in the energy consumption of residential, commercial and industrial buildings.
I am looking forward to reviewing polyurethane spray foam insulation, buttoning down its best features, how it works, what makes it green, and then providing FAQs and tips and tricks to give my readers a full understanding of this green living product. So, please come back soon and in the meantime, check out my other Living Green Reviews and please remember to visit and support my green store, so that you can also Switch it Green, Switch it Forward.
