      Great foam blocks to seal vents

      Posted by James Hayes on Aug 25th 2022

      Good quality, thickness and size to seal vents, along with caulk to seal the gaps. Would be better if one side was painted black, so they wouldn't be seen thru a screen vent cover. Do not use a solvent based paint spray to paint them as the solvent will dissolve the foam.
