Do Basement Wall Insulating Panels Require Airspace for Ventilation?
When installing insulating panels in the basement, you do not need to leave any airspace for ventilation. In fact, many manufacturers recommend avoiding leaving any type of airspace so that it does not lead to condensation forming on the walls. If you are going to glue the panels to the wall, you ensure that you do not randomly put the glue on the wall, as doing so can create a gap. Use a closed grid pattern when applying the glue so that you can make sure that it does not allow air in.
