- BioGreen is an industry leader in Florida in the application of Spray Polyurethane Foam insulation.
- We install the foam in a quality manner giving the customer what they've paid for, and when we leave the site it will be as clean as when we arrived.
- We are based in Clermont (just west of Orlando), and perform work throughout the state of FL.
- The foam is sprayed in walls, crawl spaces, on the underside of roof decks, or the top of commercial and industrial buildings.
- When properly installed in a home or building along with other responsible building materials, you can realize a 20 - 40% savings on energy costs.
The payback on the investment:
An average 2,000 square foot home with a standard 6-12 roof pitch would cost between $3200 and $4200 for spray foam (a number of variables affect the price such as project
size, accessibility of the attic, project location, existing v. new construction, roof pitch,
etc). If you could save 25% on your energy bill, or approximately $80/mo or $960/year,
then the payback would be approximately 3 years. If you include the $1500 federal
tax credit as well as local credits (local energy company) then the payoff is closer to 1 to 2 years. So...it is a good investment that will pay for itself within a few years. It is also a great selling feature when selling your home, as spray foam is becoming more
and more well-known as the gold standard in insulation.
- The foam itself expands more than 100x its liquid volume when installed, thereby filling all voids, crevices, and cracks in the attic area. This creates a thermal seal and air barrier in the building envelope and eliminates all air infiltration, which is the leading cause of energy inefficiency in your home or building. So following the installation, you have no ridge vents, and even the soffits are sealed to eliminate all air flow into your attic.
- The sealed envelope results in an attic temperature within 15 degrees of the living area, thereby becoming a semi-conditioned air space. So you won't have to deal with the usual 140+ degree attic heat in Florida summers. This balance creates efficiency.
- Our foam does not support mold growth.
- R-Values: Open-cell-3.83/in; Closed-cell-6.5/in
Comparing R-values of spray foam to R-values of 1) batt insulation or 2) blown-in cellulose is comparing "apples and oranges." An R-value of R20 in spray foam will provide substantially better insulation and energy efficiency then even an R40 in batt insulation.
- Most green building experts agree that in 10-15 years there will ONLY be spray foam in new home construction, and no longer any batt or cellulose due to the vast differences in energy efficiency.
- Approximate Cost per sf: $1.50 to $1.80/sf. Several variables affect pricing: project location, project size, accessibility of work area, roof pitch, new vs. existing, etc.
- Closed-cell vs. Open-cell:
OC: Sprayed in Central Florida 90% of the time; water soluble so if you have a roof leak will bleed thru foam and you will know it; 25% cheaper than CC; does NOT add structural strength to roof; also called 1/2# - this is the density - 1/2# per cubic foot
CC: Mainly sprayed along coast lines (hurricane-prone areas) because it adds structural (rack) strength to roof; 25% more expensive than OC; it is a vapor barrier
(not water permeable) so if you have a roof leak it will puddle; also called 2# or 1.7#.
- Spray Foam insulation extends the life of your A/C system.
- Building code in FL: R-19 required in roof deck (5" open-cell, 3" closed-cell)
- You need to wrap the 2x4 (or 2x6) studs on underside of roof deck during the spray foam application process or it will create a thermal break in the building envelope.
- Spray foam will last as long as your home or building is standing.
- General lead time for a project is 3 days to 3 weeks.
- We also perform injectable insulation into CMU block and Drywall cavities
- It is recommended to remove existing batt or blown-in cellulose prior to sealing attic with spray foam. BioGreen cost to remove existing Batt and Cellulose is ~ $.60/sf.
- On existing homes, the homeowner will receive a 30% federal tax credit on the cost of the spray foam project, up to $1,500.00. There are also local tax credits from OUC, Progress Energy, etc.
