Cold, uncomfortable floors above a crawlspace
Cold, uncomfortable floors in the winter occur when they are built over vented crawlspaces. The floor is cold because we do not treat the crawlspace as part of the building envelope.
The crawlspace is susceptible to cold air entering the crawlspace through many gaps and openings. This cold air will make the floor seem like you are walking on ice.
Common symptoms of crawl space insulation problems:
- Cold floors especially against outside walls
- Frozen or burst water pipes
- Heating system that can’t keep up during cold weather
- Cold air drafts around floor registers, through wood floors, or plumbing
- High Heating Bills
Sources of a cold air entering a crawl space are:
- Air leakage though gaps or cracks in wood components above the foundation walls
- Cold air seeping through the foundation wall from outside
- Foundation vents that are left open or won’t close completely
- Leaky or deteriorated crawlspace doors and openings
Adding fiberglass insulation to the floor is not an option as it not efficient and does not deal with the actual problem — the vents.
The only effective method to prevent cold floors, high heating bills, and frozen water pipes is to seal the crawlspace vents and openings, and install our AmeriBrite Encapsulation System.
