Open air vent
This open vent was allowing uncontrolled air to move in and out of the crawl space.
Old insulation needs to go
This insulation falling loose is ineffective and dirty.
Dirt floors
Wet dirt floors would later be flattened out and covered with material to control the moisture and dirty air.
Crawl Space before
The first place air coming into a homes starts is in your bottom levels. That means that a nasty crawl space like this can be the source of musty air going into the home and living spaces above.
Old insulation
Dirty old insulation is evidence that poor quality air was moving through the space. Insulation can act as a filter and collect allergens and other particles floating around.
SilverGlo
These panels insulate significantly better than the old batt insulation which was hanging from the ceiling of the crawl space.
Work in progress
Midway through CleanSpace installation. The walls have been insulated with SilverGlo panels and air sealed with ZypFoam.
After
Rim joist sealed with spray foam, SilverGlo panels insulating the walls, and CleanSpace covering the ground.
Insulated walls
SilverGlo panels and rim joists are sealed up with spray foam.
Vent sealed
Closed-off air vents keep the unconditioned air outside from coming into the crawl space.
