Crawl Space Insulation Services in St. Louis, Springfield, St. Charles & Nearby

Crawl space insulation can improve your home's comfort and efficiency

Fiberglass dripping off of the ceilings of a Decatur crawl space

Fiberglass insulation in a crawl space tends to soak up moisture and humidity, growing mold and eventually causing it to "drip" off the ceiling.

Crawl spaces are typically uninsulated and unsealed spaces that tend to soak up the natural cold of the earth around your home. This leads to cold floors and rooms above the crawl space, energy loss, and mold problems. For homeowners with ductwork, pipes or other utilities in the crawl space, energy efficiency problems will be worsened.

We offer moisture and mold resistant crawl space insulation materials that are designed to eliminate energy loss and help create a more comfortable home.

Before and After

    Installing CleanSpace in a Crawlspace
    After

    Many homes, like this one in Carbondale, IL., have dirt crawlspaces. A dirt crawlspace may seem harmless enough, but it can actually damage your home as well as decrease its energy efficiency. 

     

    The dirt in a crawlspace can allow animals and bugs to burrow in, as well as water vapor. A dirt crawlspace is also totally uninsulated, allowing conditioned air to escape and allowing humid, hot air in during the summer and frigid, cold air in during the winter. Dirt crawlspaces are full of problems.

     

    But there is a solution to these problems; CleanSpace™. CleanSpace™ is a vapor barrier similar to a pool liner but specifically designed for crawlspaces. This tough, tear-proof liner can block the water vapor rising from the dirt floors or seeping through the walls of the crawlspace as well as block off entries that insects and rodents use to get into the crawlspace. CleanSpace™ is also anti-microbial, meaning mold can't grow on it or get past it. Once a crawlspace is incapsulated with CleanSpace™ it is protected from not only dirt, but insects and rodents as well as water vapor and mold. This opens up an opportunity to insulate the crawlspace as well. Since no animals will be able to rip the insulation, and water vapor and mold spores can't get in to ruin it, the crawlspace is the perfect place to insulate. With insulation below the floor, the entire home will be easier to heat or cool all year round.

     

    A dirt crawlspace is full of problems, but a CleanSpace™ crawlspace can keep your home clean, dry and energy efficient. 

Signs of crawl space insulation problems

  • The floor above the crawl space is unpleasantly cold in wintertime
  • During cold weather, you have to keep the heat going nearly all the time to be comfortable in rooms directly above the crawl space
  • Mice or other pests have taken up residence in fiberglass insulation installed between joists in the crawl space
  • Fiberglass batt insulation has fallen out of place from between floor joists in the crawl space
  • The crawl space smells moldy, has visible signs of mold, and/or is damp all the time

Many homes have the wrong type of crawl space insulation

The old-fashioned way to insulate a crawl space was to install fiberglass batt insulation between joists and vent the crawl space so outside air could circulate beneath the house. Unfortunately, this combination usually leads to the problems listed above. Fiberglass insulation doesn't respond well to the moist conditions that can be found in a crawl space.

The cotton-like material absorbs moisture, gets soggy, compresses and loses R-value. Fiberglass batts often end up on the crawl space floor in a soggy mess. The main advantage of fiberglass insulation - low cost - is totally negated when the material ceases to perform its main function.

Benefits of insulating your crawl space with rigid foam

  • Stable and reliable: Unlike fiberglass insulation, rigid foam won't compress, fall out of place or lose its R-value over time. It's a "once-and-done" improvement.
  • Effective air sealing: When joints between foam panels are taped, rigid foam stops air leaks that can waste energy. Fiberglass insulation can't stop air movement.
  • Moisture-proof: Rigid foam won't absorb moisture or be damaged by it.
  • Unfriendly to mold: Mold can't take hold on rigid foam because it contains no organic food source and it doesn't hold moisture.
  • Better ductwork performance: Ducts located in the crawl space benefit from rigid foam installed against crawl space walls.

Rigid foam panels outperform fiberglass in the crawl space

Silverglo Insulation

Long-lasting. Rigid foam insulation can't be damaged by moisture and won't degrade in appearance or R-value over time. In a crawl space, it's usually installed against the interior face of foundation walls.

Rigid foam insulation performs much better than fiberglass in a crawl space. This type of insulation is manufactured in panels of different thicknesses. Installers cut the panels to fit against the interior face of crawl space foundation walls. Panels are secured with adhesive or mechanical fasteners.

We typically insulate crawl space walls with
foam board insulation. This brings the crawl space inside the building envelope, which improves overall home energy performance. This will also help make rooms above the crawl space more comfortable and can help lower heating and cooling bills.

Although rigid foam insulation costs more than fiberglass insulation, it's less expensive when you consider that you'll never have to clean up or redo a mess of damaged, ineffective installation. Rigid foam will deliver the same performance and benefits in 15 years as it does on day #1.
