Frequently Asked Spray Foam Questions
Can I install Spray Foam Insulation myself -or- should I hire a professional?
Polyurethane spray foam insulation projects (e.g., walls, attics, roofs) using two-component systems are sophisticated applications that require expensive equipment and professional installation by a trained polyurethane spray foam contractor or weatherization professional. Polyurethane spray foam professionals will have the appropriate training, protective gear and equipment to apply polyurethane spray foam insulation.
There are insulating foam sealant products available in cans for Do-It-Yourselfers at home improvement stores. These products are used for small “bead-type” applications, such as sealing windows, doors, and filling small gaps and cracks and not for the general insulation of your home or business.
What should I look for in a Spray Foam Contractor?
As with any professional you would hire for work, a few things you might want to look for in an polyurethane spray foam contractor or weatherization professional include:
- Appropriate training in polyurethane spray foam installation
- Insurance
- A good reputation and references
He/she should be able to advise you on the following:
- Where to install polyurethane spray foam insulation
- What to expect throughout each stage of the installation
- Safety precautions and technical specifications for the products being installed
As an added service, your contractor may also offer guidance on how to take advantage of local and federal utility rebates or tax credits.
CAN I BE AT HOME WHEN POLYURETHANE SPRAY FOAM INSULATION IS INSTALLED?
Two-component polyurethane spray foam insulation releases gasses with the chemical reaction of the components and protective equipment is needed while being installed. Before the job, consult with your contractor for guidance about the period of time before you, your children, and your pets may reenter your home following installation.
I HAVE OTHER CONTRACTORS WORKING IN MY HOME. WILL POLYURETHANE SPRAY FOAM AFFECT THEM?
As part of the pre-job consultation with your polyurethane spray foam contractor, discuss the other work being conducted in the home. Connect your polyurethane spray foam contractor with any other contractors working in your home in advance of the polyurethane spray foam application so appropriate arrangements can be made for their protection.
WHAT SHOULD THE WORKSITE LOOK LIKE AFTER POLYURETHANE SPRAY FOAM INSTALLATION?
You should discuss worksite expectations with your polyurethane spray foam contractor so it is clear what you can expect during every stage of polyurethane spray foam installation. Some general expectations include:
- After the installation, removal of dust, debris and foam trimmings by workers wearing appropriate protective equipment and
- removal and disposal of any empty and partially used polyurethane spray foam containers or drums in accordance with applicable federal, state, provincial and local requirements.
HOW LONG WILL POLYURETHANE SPRAY FOAM INSULATION LAST? DOES THE FOAM DEGRADE OVER TIME?
For information regarding the expected lifespan of the polyurethane spray foam insulation being installed in your home, consult your contractor and/or the product manufacturer. One of the benefits of polyurethane spray foam insulation is that it resists structural deterioration/decomposition over time and resists settling.
WHAT SHOULD I DO IF I SMELL AN ODOR AFTER POLYURETHANE SPRAY FOAM INSTALLATION?
In the event you have concerns about odors that you believe may be related to the polyurethane spray foam insulation, contact your contractor to ensure proper installation procedures were followed and a thorough clean-up was completed. If your concerns are not resolved, contact your local or state consumer protection office or local or state licensing board for contractors.
CAN POLYURETHANE SPRAY FOAM INSULATION HELP CONTROL MOISTURE IN MY HOME?
Gaps and cracks in the building envelope can allow uncontrolled movement of moisture-laden air in and out of the building. Loss of interior moisture control can make the interior air excessively dry or moist, which can cause occupant discomfort, poor indoor air quality, higher heating and cooling costs to control moisture, and in some cases, hidden deterioration of the building and possibly mold and mildew growth. Air sealing these gaps and cracks with polyurethane spray foam can help control interior moisture levels. For a list of SPF benefits, go to “Why select Spray Polyurethane Foam insulation.”
WILL I HAVE A PROBLEM WITH INSECTS ATTACKING THE FOAM?
Typically, polyurethane spray foam does not attract insects. Generally, it is known to be an effective impediment against insects and other pests because it can be used to seal the gaps from the outside where insects and rodents typically enter. Although polyurethane spray foam is not a food source for pests, some pests may chew through the foam over time.
DOES THE POLYURETHANE SPRAY FOAM INSULATION IN MY HOME POSE A FIRE HAZARD? IS IT FLAMMABLE?
Polyurethane spray foam products typically contain flame retardants and are designed to meet applicable building and fire code regulations when installed properly. Consult the product label or manufacturer for more details.
