Spray foam insulation is pretty new in the world of commercial and residential insulation. It is sometimes deemed to be the eco-friendliest and most effective insulation in today's market. This is because it can significantly reduce energy losses, while helping homeowners save money. Read on to find out more about the other benefits to using spray foam over standard fiberglass insulation.
This particular material is made out of modified urethane and polyurethane foam and is very reactive as a foaming agent. Both of these components are kept apart until they get to the spraying machine's nozzle. There they react quickly, to create a material which can expand exponentially.
Ideally, the last step prior to installing the drywall would be to directly apply the spray between wall studs. In the case of retrofitting, it is instead possible to apply the insulation through holes and let it expand to fill up small nooks and crannies. This creates an air-tight seal that stops the air and energy from escaping.
The Different Kinds of Foam Insulation
• open cell insulation, which allows vapor infiltration
• closed cell insulation, which works as a vapor barrier and provides great insulation
Both of these insulators have high R-values, which means that they are extremely resistant to temperature, when used in construction, and are very effective as insulators, in general. Spray foam insulation generally has a higher R-value, compared to other insulators. As a matter of fact, it is known to have double the R-value of fiberglass insulation.
How is It Eco-Friendly?
• It fills up every space, to stop the heat, moisture and cool air from escaping.
• It reduces the overall amount of wasted energy by up to 40%, using less energy.
• Some brands use a lot of reusable materials and are made out of agricultural-based materials. No non-green practices are involved.
• It doesn't use HFCs or HCFCs as blowing agents, nor does it use hazardous chemicals, which could affect the environment in a negative manner.
Spray Foam vs. Fiberglass
There are a lot of other insulators available in today's market, such as traditional fiberglass insulation. However, fiberglass is generally frowned upon by environmental activists, due to the fact that it uses HCFCs as blowing agents and is made out of petrochemicals. Because of this, fiberglass doesn't save a lot of energy.
Although spray foam does have its own environmental issues during transport and production, it uses up much less energy when cooling or heating a building. Therefore, it definitely deserves to be known as the eco-friendliest and most effective type of insulation out there, to date.
