You know about the benefits of foam insulation for your home, but you still have questions on whether the material that creates an airtight house can make it too tight.
Your full concern is if the foam insulation will make your home too tight, which could impact air quality and humidity.
When you are building a new home it will need to be insulated. The builder you hired will call in a Heating Ventilation and Air Conditioning (HVAC) contractor to perform a Manual J test. This test will determine the size of the HVAC system your home will need.
That HVAC system will help to keep your newly insulated home from being too tight a non-issue. It will ensure your home has the proper air exchange rate to have the proper air quality and a comfortable humidity level.
What Happens if My Home is Sealed Too Much?
The solution to a house that is sealed up too tight is very simple.
The fix is as simple as turning on a bathroom vent or kitchen hood once a day. This will exchange the air in the house so you have fresh air coming in.
No matter which kind of project you’re working on, it is very rare for spray foam to make your new or existing home too tight.
