Insulation questions, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Adding too much insulation can have detrimental effects on your home and on your wallet. Where you live will determine the optimal amount of insulation for your home and in your ceilings. Adding more than the recommended amounts can cause airflow problems that can lead to moisture trouble. You may also spend more than necessary by adding too much insulation to the point that it'll become unrecoverable through your energy bills.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Yes, the air in your home needs some release; otherwise, moisture can get trapped inside the layers of insulation and potentially lead to mold and mildew. An insulation contractor near you should be able to determine the precise amount of insulation that will seal your home, keep you comfortable, and not lead to any mold.
