As conscience homeowners, we’re regularly searching for products that increase energy efficiency in our homes and reduce energy costs. Spray polyurethane foam (SPF) insulation is one of the more popular products on the market to help achieve just that. It is a spray-applied cellular plastic, is made by mixing chemicals to create foam, which quickly expands to insulate, air seal, and provide a moisture barrier.
Benefits of SPF insulation include:
- Savings on energy use
- Reduces heating and air conditioning equipment size
- Reduces drafts and noise
- Impedes the entry of insects and pests
- Deters mold
- Resists settling
- Seals small cracks
- Prevents ice dams
Although SPF insulation provides many benefits, there are also concerns to keep in mind before moving forward with installation. Know what might go wrong and how your professional will handle these situations:
- Improper installation
- Bad mixing
- Wrong temperature
- Incorrect proportions
- Too thick
- Too much light
- Too much moisture
- Chemical off-gassing
- Chemical off-gassing from SPF insulation should be complete within a few hours to days with proper application and ventilation measures. However, if something went wrong during installation, this off-gassing could continue long after application.
- Difficult Removal
- If removal is necessary, this task will be extremely difficult. Aspects, such as its impermeability, that make SPF insulation function as such an effective insulator also make it difficult to remove.
If you’re considering energy efficiency improvements with SPF insulation, research is crucial. Perform your due diligence when it comes to hiring a professional for installation. Ensure they, at a minimum, meet the following requirements:
- Possess the appropriate certification in SPF installation.
- Can provide proof of sufficient insurance coverage for repairs/replacement, if needed
- Previous experience and knowledge to accurately advise on the following:
- Where installation should occur
- Which type to use
- Safety precautions
- What to expect during each stage of installation
- Re-occupancy guidelines
Adding SPF insulation in your home is a great way to save money, cut down on drafts, and seal those nooks and crannies. Become an informed consumer and keep these possible issues in mind when searching for a contractor to complete the task. Choosing a knowledgeable installation professional and knowing what questions to ask will aid in keeping your home both happy and healthy.
