Fill every open space
By the nature of its construct, fiberglass insulation cannot properly seal and it’s almost impossible to create a solid thermal barrier so that air cannot pass through. However, due to its unique qualities, spray foam insulation can readily address this situation. It has the properties to fill every open space in the most effective and efficient manner.
The ceiling of a crawl space can be spray foam insulated in either a ventilated or unventilated approach.
As a vented crawl space, the ceiling may be insulated, thereby reducing heating and cooling costs.
For an unvented crawl space option, the space would receive similar temperature conditions to the rest of the premises.
A research study was conducted in North Carolina, and it was proven that homes with sealed crawl spaces and insulated foundation walls use 18% less energy for heating and cooling homes than those with vented crawl spaces.
Some of the crawl space issues that are addressed with spray foam:
- Cold and uncomfortable floors
- Exposed plumbing
- Sagging insulation material
- Moisture build-up on floor insulation
- Buckling hardwood floors
- For HVAC systems, sweating ductwork
- Energy loss due to leaky ductwork and HVAC inefficiency
