Spray foam is usually made up of a mixture of isocyanates and polyol resin which combine at the nozzle of a spray gun when spraying. The mixture forms an expanding form as it is sprayed onto the surfaces such as wall cavities, roof tiles and concrete slabs among others. You will need to hire a professional applicator to help do Foam insulation Wichita KS for you. Visit website for more details.
Types of foam insulation
There are two types of foam insulation:
- Open-cell- this foam does not close the cells completely as it is less dense. It is less expensive as it uses fewer chemicals and is easier to apply. In addition, it provides a good barrier to air but is less effective in insulating against water vapor. However, it is not recommended to apply this type of foam on the exterior.
- Closed-cell- this type is denser, smaller and compact cell structure, unlike open cell foam. It acts as a good barrier to sound and water vapor and can be applied in the interior and exterior of the house. It uses a polyurethane that has low conductivity gas.
Benefits of using closed-cell foam insulation
Although closed-;cell is more expensive to apply; its benefits exceed the initial cost of spraying it. It also has the following benefits
- Prevents the growth of mold- the foam insulation reduces the growth of harmful mildew and mold by minimizing the entry of moisture into your home. Controlling the growth of mold helps eliminate the rotting of wood furniture, and allergic reactions caused by mold spores among the occupants of your home.
- Reduces noise- Spray foam insulation acts a second barrier to loud noise that may emanate from the environment.
- High R-value- closed-cell foam has a high R-value meaning that there will be greater resistance to heat loss or gain. It blocks three forms of heat transfer which include conduction, radiation and convection.
However, closed-cell foam insulation has some shortcomings which include:
- Exposure to isocyanates can cause irritation to the eyes and direct inflammation to the skin
- The agents that propel the foam out of the spray gun are made of hydrofluorocarbon (HFC) agents that are potential greenhouse gases.
To realize these and other benefits of Foam insulation Wichita KS, consider hiring a professional applicator from NorthStar Comfort Services.
