Sealed Crawl Spaces
Other than heat and ultra-violet radiation, water is one of the most damaging elements that
destroys materials and wood in particular.
An unconditioned or vented dirt or concrete crawl space creates an unhealthy environment.
The high relative humidity levels in the mid-west allows damp air to move easily into your
crawl space and up into your home.
In these high humidity, damp environments, mold thrives and spreads by producing millions
of airborne spores, some may even be toxic. Allowing hot and cold air into the crawl space
drives heating and cooling costs way up, especially if you have a ventilated dirt crawl space.
A damp, dark crawl space will attract all kinds of insects and critters, and promote rot and
decay which leads to structural damage.
Crawl spaces do not have to be wet or flooded to be extremely unhealthy.
The ''stack effect'' is the natural airflow in a house - from bottom to top, like a chimney. 60% of
the air in your house comes from the crawl space. Moist air and everything in it is sucked up
into the living areas of the home. Mold spores, odors, humidity and critters cause unhealthy
air quality. Many people are allergic to these things and experience a host of symptoms. What
they don't realize is that their dirt crawl space is affecting their health.
The Solution
We have the solution to ventilated dirt and concrete crawl spaces - The Barricade Sealed
Crawl System
The goal of a sealed crawl space is to turn your home and crawl space into one conditioned
unit. After all, if you had a basement would you leave the windows open year round? Would
you buy a house with a basement that had a dirt floor? Probably not. We must treat the crawl
space no different than we would a basement.
Our system completely isolates your home from the earth, dramatically reducing the humidity
level in the air. Lower humidity levels reduce or, in some cases, eliminate mold growth, rot,
and critters from your crawl space, making your entire house healthier.
The Bilar liner is a heavy 15-mil-thick material, similar to a pool liner. It is a multi-layer blend of
high and low density polyethylene and two layers of polyester-cord reinforcement. The bright
white finished side brightens a crawl space and allows you to easily see that your crawl space
is free of mold, insects and dirt. The Bilar liner is durable enough for you to crawl on and use
for additional storage. Moisture penetration is completely eliminated.
For additional energy savings, we offer our CIB R-10 wall insulation as an option.
