There are a number of practical applications for this type of insulation. Small or difficult to reach areas, like door frames are easily insulated with this type of insulation. Despite the fact that this type of insulation is ideal for smaller areas, polyurethane foam spray insulation can be employed to completely insulate a home or building. Because of the complexities and health hazards involved, only professional contractors should attempt large-scale installation projects.
According to Ask The Builder, the R-value that is assigned to insulation is a measurement that refers to heat flow levels through the insulating material. Fiberglass insulation that is rated with the same R-value as polyurethane foam spray insulation tends to be 2 to 3 inches thicker, according to R-Value. Since polyurethane foam spray insulation can be sprayed to desired thickness, consumers have more control over the R-values in their homes.
According to ESP Energy, polyurethane foam spray insulation emits toxic fumes, which can be very harmful if inhaled. Respirators or another form of protection should be used to prevent lung damage from exposure to fumes while installing this type of insulation. According to Thomas Net, blowing agents utilized in some polyurethane foam spray insulation emit dangerous greenhouse gases.
In general, polyurethane foam spray insulation is more expensive than other types of insulation like fiberglass. Depending on thickness, polyurethane foam spray insulation can cost between $1.50 and $2.50 to have professionally installed. However, unlike fiberglass, polyurethane foam spray insulation will experience a slight decrease in effectiveness as the years pass. Canisters of polyurethane foam spray insulation can be purchased for small home improvement projects or repairs.
Ask The Builder claims that foam insulations like some polyurethane foam spray insulations are highly flammable, much more so than fiberglass insulations. Eye overexposure to polyurethane foam spray insulation can lead to temporary blindness. Eye goggles or face shields can be used to prevent damage to the eyes. A small number of consumers may experience an allergic reaction after coming in physical contact with polyurethane foam spray insulation, according to the Center for the Polyurethanes Industry.
