Safety Tips for Spray Foam Insulation

May 25, 2016

Many homeowners often ask which insulation is best. And while every project has different needs and priorities, one product has proven to be consistently effective across the board - spray foam insulation. From all respects, it's the best - it does exactly what insulation should do. At the same time, this is an installation project for professional contractors. They understand the nuances of the product; they understand the intricacy of the application; and they understand how to install safely and responsibly, thus protecting themselves and their homeowners during the process. By any definition, spray foam insulation is a complex chemical compound. It means that careful handling of the product, and safe operation of the equipment, is paramount on every job. Without the professional touch, there are dangers and risks for everyone involved, not to mention defects in performance when the job is complete. The truth is, even the best product on the market will not perform at peak when installed improperly. Reputable installers must be trained, qualified, and certified to ensure installation excellence, and high safety standards from start to finish. For homeowners deliberating spray foam insulation, price shopping should be avoided. Industry accredited products must be installed, and contractors must guarantee their work. This is the only way to ensure the highest quality of work and the safest approach to installation. It's work that requires absolute compliance when it comes to health and safety regulations. Installers must wear proper respirators (with outside air supply); personal protective clothing (coveralls and gloves); and provide the required equipment to ensure appropriate ventilation for the space. Homeowner safety is another important element when spray foam insulation is being installed. There are strict regulations for occupants during an installation, and strict rules for contractors to follow. Installation shortcuts and careless workmanship only sets the stage for risk and hazard - the aftereffects can be unfortunate and costly. With spray foam insulation, there's every reason to do it right the first time. For the homeowner, it means understanding the basics of the product and application, and properly researching insulation contractors who are reputable and reliable. At Great Northern Insulation, installation crews are expert in their field. They understand the uniqueness of the spray foam product. They follow best practices. They abide by building codes. And they install according to manufacturer specifications. As a company, GNI sells and installs only the best insulation products on the market, and stands behind everything that is installed. In the event that there are deficiencies with an installation, GNI will repair to the industry standard. With GNI, customers can be assured that every job, large or small, is done right the first time. Importantly, the team at Great Northern Insulation will discourage a customer from engaging in a DIY (do-it-yourself) project with spray foam insulation. And while there may be cost savings with a "spray foam kit" available at the local home improvement center, the risks associated with inexperience just aren't worthwhile. This is work for professionals who know what to do.
