What does Bio-renewable mean?

Aloha Foam is produced from plant-based and recycled renewable resources such as castor bean oil, sugar, soy and oil from the shells of cashew nuts. Our foam has the Highest Percentage of renewable resource ingredients in the industry, over 50% on the “B’ side.

Is Bio-renewable spray foam more expensive than Petroleum only spray foam insulation?

Sometimes no, sometimes yes; depends on commodity markets (soy, castor beans, sugar…) and the price of oil. Historically within 10% +or- as a rule, of actual cost, but always less if you consider the entire cost to the environment of using our limited petroleum reserves to make it the other way

How does bio-renewable spray foam insulation compare to petroleum based spray foam insulation?

Aloha Energy’s bio-renewable spray foam produces significantly less effect on the environment. Its use of castor bean oil, sugar, soy and oil from the shells of cashew nuts in place of petrochemicals reduces its carbon footprint. Using water as the “blowing agent” as opposed to petrochemical based blowing agents results in lower effective greenhouse gas emissions, increased pre-installation product stability at a wider range of temperatures and a longer shelf life.

How does spray Foam Insulation save on energy costs?

Spray Foam insulation saves on energy costs and lowers utility bills. Spray Foam Insulation is used to seal the entire “building envelope” of your home to prevent air and moisture infiltration. The US Department of Energy (DOE) studies show that 40% of your home’s energy is lost due to air infiltration. This air infiltrates the home in the form of drafts through walls sockets, windows and doorways.

Monthly energy and utility savings of 30% or greater can be achieved when compared to the alternative roofing and insulation systems. The cost of a complete Spray Foam roof and wall insulation system can often be recovered in less than 5 years, simply through energy savings alone.

Often times no expensive building wrap or additional vapor protection is required during construction when using Spray Foam, saving money and labor yet again.

Does spray foam support bacterial or fungal growth?

Polyurethane Foam Insulation has zero food value for bacterial or fungal growth and since it also acts as an air and vapor barrier, along with the installation of an HRV/ERV system, accurate control of fresh air and moisture levels in the home can be gained thereby avoiding the conditions that promote the growth of dangerous mold and mildew in the home.

Do insects and vermin eat spray foam insulation?

Unlike wood, spray foam offers no food value to them but like wood it would not present a sufficient barrier to their entry if they decided to chew through it (but with a solid castor content it won’t taste very good).

What’s the difference between open and closed cell foam?

Open Cell Foam Insulation is a somewhat porous material that can allow water vapor to penetrate the insulation, if the moisture differential is high and prolonged. Closed Cell Foam Insulation is non-porous with all of the voids closed to each other which makes it impossible for water vapor to pass through it. The vapor porosity of the two materials is the biggest difference and most important issue, but both are impervious to air transmission.

The other major difference between open cell and closed cell foam insulation is the density of the in-place foam. Open cell foams typically weigh about 0.5 lbs per cubic foot while closed cell foams have classically been 1.7lbs per cubic foot and up. Closed cell foams are stronger and denser allowing them to carry heavier loads. This is also one of the reasons that closed cell foam is quite a bit more expensive compared to open cell foam per board foot.

The final issue when discussing the differences between open cell and closed cell foam insulation is the insulating value or R value per inch of insulation. Our open cell foam insulation typically has average R values of about 3.6 per inch while our closed cell foam insulation has average R values of about 6.5. So you can see closed cell foam insulation can be almost twice the insulating values per inch.

Is Spray Foam Biodegradable?

No! Spray foam is inert and will last indefinitely. Once the foam reaction is complete, you are left with an inert, cellular plastic. It will never sag, shrink, settle or disintegrate.

Do any of your products contain Urea Formaldehyde?

NO, Aloha Energy’s products do not contain any urea formaldehyde what so ever. We are also free of all VOC’s and ozone depleting CFS’s or HCFC’s

What is Energy Star?

ENERGY STAR is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency.

What is LEED?

Leadership in Energy & Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies intended to improve performance in metrics such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Developed by the U.S Green Building Council (USGBC), LEED is intended to provide building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

What are the acoustic properties of spray foam?

Open-cell spray foam offers optimal sound-deadening qualities. As an effective air seal, Aloha’s open- cell foam eliminates the air gaps through which sound travels and is superior in controlling mid-range frequencies which include the most common sounds; the human voice, stereo music and plumbing noise. A lot of the sound waves are absorbed as they try to find their way through the foam. Closed-cell foam is a bit less effective as a sound deadener as it is so dense that the vibrations can be transmitted thru the foam more directly, but compared to fiberglass it’s still quite superior.

How does bio-renewable spray foam insulation compare to fiber glass insulation?

Spray Polyurethane Foam (SPF) Insulation Prevents Air, Moisture and Gas Infiltration. Studies have shown that as much as 40% of a building’s total energy loss is due to air infiltration. Traditional fiberglass insulation is only stapled, or placed into the wall cavities and does not seal the stud and wall cavities from end to end, or top to bottom. Air infiltration can pass through these gaps and thru the loose fibers themselves as well, making it far less efficient than SPF. In fact the actual R-values of a fiberglass insulated wall are usually no where near their “rated” insulation values). SPF not only adheres to, but forms to the walls and floors to create an airtight seal and insulating barrier that stops this air leakage. SPF also boasts the highest R-value per inch of any commercially available insulating material, (upwards of R-7.0, compared with Fiberglass’s rated R-3.5) making your home more comfortable and less expensive to heat in the winter, and cool in the summer.

Does spray foam insulation add structural integrity to a building?

Higher density, closed cell spray foam insulation inside your stud walls fully adheres to both the exterior sheathing and the studs, reinforcing both. With this added rigidity, there will be less wall movement due to wind, vibration, and occupant activity. Additionally your walls have greater than code required resistance to “racking events” such as hurricanes or other strong wind situations.

Spray Foam also can add structural strength to buildings. NAHB Research demonstrated that closed cell spray foam filled walls could add from 75% to 200% racking strength to walls of OSB, plywood, light gauge metal, vinyl siding or gypsum board. When insulating with SPF you’re essentially gluing the entire home or building together.

Can spray foam be installed by the homeowner?

Currently NO: Spray Foam Insulations should ONLY be installed by certified, trained installers. Specific equipment and training is required to insure safe and correct application. Please contact Aloha Energy at 518-852-2812 to find the nearest certified independent installers.
