3 Dos and Don'ts When Using Can Foam Insulation 3 Dos and Don'ts When Using Can Foam Insulation

Can foam installation is best for small insulation projects such as sealing cracks in the windows or the doors, or sealing gaps, holes or crevices. Since foam insulation prevents entry of air inside the home, it provides a cost-effective way of saving a lot of energy. Some insulation materials, such as fiberglass, do provide cheaper cost, but not in the long run, because they tend to produce air gaps that can reduce the R-value of the insulation. When using can foam insulation, here are some do's and don’ts to consider.

During Preparation

Remember that can foam insulation applications require some preparation from hazards or accidents so take into consideration careful preparation before proceeding with the application. Do wear eye protection because the chemicals in the can cause blindness when it comes in contact with the eyes. Do not wear new clothes because contact with the foam can ruin new clothes. Make sure to wear old clothes or disposable clothes. The foam is a very strong adhesive and can therefore bond with anything it comes in contact with, unless the foam already dried up, so do provide protection to shoes and pants as well. It even bonds to skin so do use rubber gloves. The rubber gloves will also protect people allergic to some of the components of the product.

Make sure to provide ventilation on the working area to allow the fumes to escape as it may cause respiratory problems after prolonged exposure. When working in a closed space, use a respirator.

During Application

Do read the instructions on the spray can before using it. The manufacturer will also include important safety tips that will be useful during application. There are different types of spray foam in cans so make sure to know the difference and choose the product that is well suited for a certain project or application.

Can foam insulation should only be used for small insulation applications. Never consider using it for larger projects that require the insulation of larger areas. Make sure to spray the foam evenly on the holes or crevices. In addition, do spray only halfway through cracks and gaps because the foam will expand to fill-in the other half. Spraying too much will put the extra foam to waste.

Aside from cracks on doors and windows, spray foams in cans can also be used for other types of applications. Do use it to fix gaps or cracks in pipes, tanks, and any other material in need of insulation. Know that spray foam can bond to any type of material such as glass, metal, wood, and just about anything.

During Disposal

Do not dispose spray foam cans that are not empty. Use up all the contents of the can before throwing it into the garbage. If the can is not yet empty, let the excess foam come out of the can before throwing it. Do not spray the contents of the can in an open flame as well because the fumes that are diffused from the chemicals are toxic.
