Spray Foam Insulation Reviews
Insulation is one of the best ways to reduce your heat and air conditioning bills. You can add it to the attic and crawlspace to reduce the amount of outside air that enters your home. This also reduces the amount of hot or cold air that escapes through the many cracks and crevices in your home. Spray foam insulation will seal the area creating a more energy efficient space. Spray foam insulation can be used during renovations to provide a barrier between outside walls and a sound barrier with interior walls. We have selected the best spray foam insulation material that will provide for easy application as well as a sealed area that will reduce your heating and cooling bills for years to come.
Spray Foam Insulation Buying Guide
Spray Foam Basics
Most homes are heated during cold seasons such as winter. This may be an exercise in futility if there are air leaks, holes and cracks in your home. Insulation helps to conserve the heat having a direct impact on the efficiency of your heating system. Unfortunately insulation may not cover all the holes, cracks or air leaks in your home. According to energy star about 40% of your monthly heating and cooling bill is wasted because of these gaps in your home.
Unfortunately this is true of houses which have cellulose or fiber glass insulation. To reduce the losses most people just increase the amount of insulation.
Because of their low cost, most home builders prefer cellulose or fiber glass insulations. They cannot efficiently stop heated air from escaping. They absorb moisture causing them to be prone to mold . On the other hand spray foam insulation cannot absorb water and seals out air infiltration or exfiltration.
Spray foam insulation is a two component mixture of isocyanates and polyol resin. Heated hoses convey the chemical to a mixing gun that sprays the mixture on the surfaces to be insulated. A chemical reaction between the components causes the foam to expand and then harden. Since it is foamed -in -place, the insulation easily fills walls and ceiling cavities. This makes spray polyurethane foam (SPF) more effective at reducing air leakages than any other insulation.
The R-value per inch determines the effectiveness of insulators. The higher the R-value per inch of the insulation product, the more effective the insulation. Closed cell insulation foam has an R-value of 6.5 while open cell insulation foam has 3.6. Cellulose and fiber glass have R-values per inch of 3.5 to 3.7 respectively ergo they are cheaper.
Pros and Cons
Advantages of Spray Foam
R-value describes the thermal resistance to heat flow by an insulation product. The high R-value foam insulation makes spray polyurethane foam (SPF) more effective at reducing air leakages than any other insulation. The effective insulation saves on energy coasts and lowers utility bills. Polyurethane foam insulates 50% better than traditional fiber glass and cellulose insulations. This reduces the 40% of the homes energy lost through air infiltration and exfiltraton. The higher the R-Value of an insulation product the more effective the insulation
The vapor retardant polyurethane spray foam protects buildings against moisture. This prevents the occurrence of mold and mildew. It can therefore be used for outdoor applications as well as indoor applications. Its strong and solid structure adds structural support.
Spray foam is often used to reduce noise in addition to heat and moisture control. It reduces the transfer of air borne sound thus acting like a sound barrier through doors, walls or floors. it also improves the air quality by sealing out allergens
Unlike cellulose insulation products, spray foam insulation has no nutritional value so pests do not want to eat it making it pest resistant
It is simple to apply spray foam insulation because you spray it like paint. This also makes its application quick and easy.
Safe: spray foam insulation has no CFC’s, Penta –BDEs or urea formaldehyde
Foamed in place insulation allows spray foam insulation to seal all the cracks, holes and air leakages. After it’s sprayed, spray foam expands 30-100 times more than its original volume. This capability allows it to expand and contract with the building.
Durable and long lasting : one you have installed spray form insulation you will do it once and for all
Cost effective: it may be a bit more expensive than the traditional cellulose and fiber glass insulation but when compare to the energy savings the investment n spray foam makes economic sense. Homes treated with foam insulation more often than not qualify for federal tax deductions in the US
Disadvantages of Spray Foam
Isocyanates found in spray foam insulation are irritants to the eyes, skin and respiratory track. Over exposure to isocyanates makes the workers subject to asthma attacks. Continuous exposure progresses the respiratory irritation to chemical bronchitis then to asthma attacks. Exposure to the skin may cause inflammations while the eyes feel like they have sand.
Expansion damage: after being sprayed insulation foam expands up to 30-100 times its original size. This considerable expansion force may damage anything that tries to stop it.
Spray polyurethane foam is toxic in liquid form and only becomes non toxic after it has cured.
It is messy to apply. The spray mixture can get on to your hair your clothes and above all your body.
Types of Spray Foam Insulation
There are two types of polyurethane spray foam namely:
Open Cell Foam Insulation
It is sponge- like in appearance and the tiny cells are not completely closed .because t uses less chemical during manufacture it is less expensive . Although it is a very good air barrier it does not provide any form of water vapor barrier. For this reason, it is not recommended for outdoor applications. It has good sound reduction characteristics and thus used for many interior walls
Closed cell foam insulation
The tiny cells in the foam are smaller and more compact than cells in open cell. This makes it denser. Therefore it is a good air barrier as well as water vapor barrier. For this reason it can be used for both outdoor and indoor applications. Its often used n roofing projects
From a resource use point of view, open cell products use significantly less material. This makes them attractive to builders. However when open cell foam is used in cold climates a vapor retarder should always be included. The vapor retarder is a paint that is sprayed on a wallboard (gypsum) to make it effective. Without the wallboard, research has shown that the vapor retarder paint is ineffective
Open cell foam is riskier than closed cell foam when under a roof sheathing. Water can reach the timber structure if open cell foam is used. This may compromise the timber because water cannot drain or evaporate leading to saturation and rot.
