What’s the true relationship between insulation and airflow in Sacramento, CA? Does insulation prevent air leaks? This is a common misconception. Here are the facts, so you can install insulation properly and have realistic expectations about what this product will do for your property.
Insulation is an insulator, not a blocker
Yes, insulation is often added to parts of the property where air leaks occur. However, the role of the insulation is not to block this airflow. It actually does not do much at all to prevent any unwanted airflow.
Instead of blocking the leaks, the insulation… insulates. It acts like a thermos. It provides an additional layer of material to keep your property cool in the summer and warm in the winter. As your HVAC system pumps cold or hot air, the insulation prevents that air from radiating through the walls and escaping to the outdoors. It also insulates the interior from the heat of the sun and the cold winter air.
What about foam spray?
It might be tempting to think that certain types of insulation are better at preventing air leaks. The fact is, the same relationship exists between insulation and airflow in Sacramento, CA no matter what type of insulation you install. Spray foam insulation may look like it blocks leaks, as it fills in the cracks, but it is still designed to act as a thermos, not a leak blocker. The air can easily flow through the foam as with other types of insulation.
So how can I block air leaks?
If you’re looking for a solution to stop air leaks at your property, other methods will be more effective than trying to use insulation. Apply weather stripping and caulk to stop small leaks. Gypsum board is the most effective method. It blocks roughly 80 percent of air leaks. Applying siding stops another 12 percent.
