Why A Home That’s Sealed And Insulated Also Needs To Be Ventilated
In the past, there was no need to ventilate old homes because they weren’t made to be airtight.

These days, however, energy prices are much higher, and we have a much better understanding of how to conserve energy and stay comfortable.
