Topic - Long term durability and R Value
(R value insulation ratings are used to measure insulation's ability to resist heat flow. The higher the R value, the more effective it is.)
Fiber Products - Fiberglass insulation usually has an R-value of approximately 3 per inch. Cellulose insulation has an R-value of 3.8 per inch. Both traditional types of insulation (overtime) settles under its own weight and can reduce the R-Value by 20% leaving you to replace, or add more insulation to your home.
Spray Foam Insulation - R Value = 6 per inch. Does not shrink, or change shape once it has expanded and is set in place. The R-Value never deteriorates and will last the buildings lifetime, so that you will never have to replace or add more insulation to your home.
Topic - Air Leakage and Annual Heating Costs
Fiber Products - Cellulose and Fiberglass do not stop air leakage. Air Leakage through walls and ceilings is responsible for about 40% of annual air conditioning and heating costs. In addition if there are any punctures in the poly or gaps left then your annual utilities bills can increase over time.
Spray Foam Insulation - The 40% of air conditioning and heating costs attributable to air leakage is virtually eliminated when applying spray foam insulation to your substrates. You will see a significant drop (about 50%) in your monthly utility bills.
Topic - Air Quality in your living spaces
Fiber Products - Outside air through walls and ceiling cracks and openings, allow heat, sound, moisture, dirt, and allergens to be transported through the insulation's porous air spaces and into interior living spaces. Fiberglass can leave gaps around obstructions such as pipes, and vents. Fiberglass batts do not fit properly into spaces and therefore leaving areas unprotected. This could make for poor air quality in your home.
Spray Foam Insulation - Spray Foam expands when applied, filling and sealing even the tiniest cracks and crevices. This eliminates air movement through the exterior walls. This frees you and your family from harmful air spaces and leaves good air quality throughout your home.
Topic - Mold, Mildew and Bacteria
Fiber Products - Dirt and moisture carried into the insulation air pockets create breeding conditions for mold, mildew and bacteria. The air pressure can eventually force harmful organisms in the your living space.
Spray Foam Insulation - Spray foam has a solid barrier, which means no pathways through insulation for dirt or moisture to accumulate, which means that mold, mildew and bacteria can not grow.
Topic - Installing your insulation
Fiber Products - Fiberglass batts, blown-in fiberglass, and cellulose can be installed by the home owner.
Spray Foam Insulation - Must be installed by a professional.
Topic - Strength of your house structure
Fiber Products - Fiberglass and cellulose insulation do not contribute to the strength of your walls or roof in your home.
Spray Foam Insulation - Medium density spray foam (closed cell spray foam) can double the strength of the walls and roof.
Topic - "the bottom line" The Cost
Fiber products - Fiberglass and Cellulose insulation are roughly the same price and both inexpensive and very affordable for home owners. Also you can rent equipment and install both types of insulation yourself which lowers the costs even more. There are still extra costs for vents, vapor barrier, equipment and tools.
Spray Foam Insulation - The initial investment for both Opened and Closed cell spray foam is the most expensive option on today's market. The most intriguing reason why people turn to Spray Foam Insulation despite the costs of the product and the install is for the Low energy bills in the future. "Spend now and Save Later" seems to be a very fitting description for this type of insulation. For Lefebvre Insulation it is important that we all try to lower our energy consumption to make our planet and ozone layer a better place for all of us to live.
Topic - Air Barrier, Vapor Barrier and Thermal Insulator
Fiber products - Both fiberglass and cellulose do not have an air barrier or a vapor barrier. You will need to add these materials (poly) and house wrap in order to meet building codes. The problem with conventional vapor barrier is that it is easily damaged. In a perfect world, where you don’t hang a picture on an outside wall of your house, poly is fine. For each picture you hang on the perimeter wall of your house and puncture the poly an estimated 1 cup of water per season comes through that hole in the poly. In addition it's a great opportunity for mold and mildew as well as a lot of dusts, pollens and pollutants to enter your home.
Spray Foam Insulation - Closed cell medium density foam can act as a vapor and air barrier, as well as an insulator, meaning that fewer materials are needed on a job site. Opened cell low density foam can act as a air barrier and a thermal insulator but you will need to add a vapor barrier for this type of spray foam.
Topic - Environmentally friendly - The Greener Choice.
Fiber products - Cellulose insulation is manufactured from finely shredded newspaper that is chemically treated for fire and mold resistance. Considered very green due to its highly recycled content, however, it is also made in electrically-driven mills that eat up a large part of our energy. (750 BTU's per pound) Fiberglass insulation which consumes 6,000 to 15,000 BTUs eats up even more energy. Fiberglass insulation manufacturers are incorporating some recycled materials into their products. However, several fiberglass insulation manufacturers (not all of them) still knowingly use phenol-formaldehyde binders in their batt products. Formaldehyde, since 2004, is classified as a known carcinogen by IARC.(1) Fiberglass insulation can be considered green mainly on the fact that it insulates.
Spray Foam Insulation - PolarFoam PF-7300-0 http://www.polyurethanefoamsystems.com/ is made from annually renewable Soybean oil and recycled plastic bottles. 40% recycled plastic bottles, which means there are about 1000 plastic water bottles in every tank of spray foam.It also utilizes a Zero Ozone Depletion Substance. A building that is insulated and sealed with this type of spray foam will also use 50% to 80% less energy, reducing fossil fuel usage and decreasing greenhouse gas emissions.
All types of insulation are essentially "green" products to some degree. However government research shows that Spray Foam not only contains varying degrees of renewable resources in its formulation, but the energy saving characteristics alone, significantly reduce fossil fuel consumption and electricity requirements for heating and cooling your home or building. These superior performance capabilities are quickly being recognized by the government, all construction trades, home owners and by insulation companies like us. Spray foam by far is the most popular, clean, sustainable green insulation product today.
Topic - Rodents, Bugs and Other Pests
Fiber Products - It is a fact that rodents can penetrate your house and are able to get through or around small areas that fiberglass and cellulose insulation can not reach.
Spray Foam Insulation - "Rodent Barrier" is the term we use for keeping pests out. SEALECTION 500 insulation offers no food value, but it would not present a sufficient barrier to their entry if they decided to gnaw through it. Normally, pests take "the path of least resistance" and if they cannot detect a food source then they would normally not attempt to go through. In this sense, SEALECTION 500 acts as a physical barrier and an odor barrier that has shown to significantly reduce the number of pests entering the homes. Studies show that medium density spray foam (2bls foam) is rigid and impossible for little pests to go threw. It completely encapsulates any areas of your home and leaves you with out any unwanted pests.
Topic - Sound Barrier
Fiber Products - Fiberglass insulation has no sound barrier qualities besides filling an space but Cellulose provides a sound barrier with its densely packed material. Sounds from the outside like traffic and aircraft are filtered and inside noises like television, radios and conversations are subdued.
Spray Foam Insulation - SEALECTION 500 Insulation (The Sound Barrier Foam) has excellent sound absorption properties and sound transmission properties. When comparing SEALECTION 500 to other insulation, there is a very noteworthy difference. As an effective air seal, it eliminates the air gaps through which sound travels easiest. SEALECTION 500 Insulation is superior in controlling mid-range frequencies that include the most common sounds, the human voice and stereo music.
