| What
are the benefits of SPF? SPF is environmentally
friendly, contains no formaldehyde or ozone depleting chemicals,
saves energy* and reduces the use of fossil fuels, thereby
reducing global warming gases. It also assists in providing
good indoor air quality, requires less energy to produce than
the leading insulation, and reduces the amount of energy required
to transport and install it. SPF is durable, maintains physical
properties over time, contributes little to the waste stream,
and in a single product (depending on the formula and project)
can take the place of three-four other products, including
insulation, air barriers, sealants, vapor retarders, and weather
barriers.
SPF reduces energy use in the following ways:
- Has high R-value per inch (open-cell 3.5 per inch and
closed-cell 6.0 per inch)
- Eliminates air infiltration
- Helps control moisture and condensation
- Reduces convective currents in walls and attics
- Eliminates wind washing
- Effective at low and high temperatures
- Provides the correct environment so that the ventilation
system performs more efficiently
