A dry, healthy home starts here.
At Basement Systems, our experts insulate crawl space walls with our innovative SilverGlo™ Insulation.
This highly efficient insulation product provides a built-in radiant heat barrier and vapor barrier.
The insulation is waterproof, while its reflective surface maximizes the effectiveness of available lighting.
As energy prices continue to soar, homeowners are looking more than ever for ways to conserve energy in their home. By sealing and insulating a home properly, homeowners may save hundreds of dollars or more on their annual utility bills!
As the search continues, many homeowners are looking towards one of the obvious culprits: vented crawl spaces.
Crawl space vents are entryway points for cold winter air, as well as summer humidity -- both of which can place an unnecessary burden on your home's utilities. By sealing and insulating your crawl space, you can eliminate this drain on your utilities, saving you significantly on your energy bills.
We can seal and insulate your crawl space quickly! Our crews can typically complete a complete installation of a warrantied crawl space system in less than a day.

There are four basic types of crawl space insulation. Understanding the advantages and limitations of each type will help you to come up with the best energy upgrade strategy for your crawl space.
What follows is how the four common types of crawl space insulation measure up:
Fiberglass insulation is created from very fine fibers of glass, and is typically pink or yellow in color. This is the oldest type of crawl space insulation, and is typically installed between the floor joists of the crawl space "ceiling". is made from extremely fine fibers of glass.
The strategy of insulating the crawl space by installing fiberglass batts between the floor joists is ineffective for a number of reasons. First of all, batt insulation does nothing to halt air movement. This means that crawl space air that's either too hot or too cold can easily pass through the insulation, making its way into the living space above through cracks, gaps, and holes in the floor assembly.
Additionally, fiberglass batts compress easily, absorb moisture, and tend to fall out from between joists. When this happens, the value of the insulation is lost, and the crawl space becomes a messy, unpleasant area that's likely to support mold growth.
This insulation forms an expanding foam when sprayed. Closed-cell spray foam creates a vapor barrier as applied.
Whether applied from disposable cans or large containers, closed-cell spray foam is valued for its ability to stop air leakage, while also providing high insulating value.
Because it expands to fill gaps and cracks, spray foam is best used to air-seal and insulate the rim joist that extends around the house at the top of the foundation. This is where most energy-wasting air leakage takes place in a crawl space or basement.
Closed-cell spray foam can eliminate this threat to comfort and energy efficiency. Another advantage with spray foam is that it stays in place; it won't move, compress or lose its insulation value like fiberglass batts.
Closed-Cell Spray Foam Is Available In Two Forms:
"One-Part" Spray Foam: Pressurized cans are available at hardware stores and home centers.
"Two-Part" Spray Foam: Most often used by insulation contractors -- combines two compounds at an application nozzle.
This insulation forms an expanding foam as it's sprayed. Open-cell foam does not seal out moisture.
Because open-cell spray foam does not create a vapor barrier as it's installed, it is inappropriate for use in a crawl space environment.
Closed-cell spray foam has a higher insulation value: about R-6 per in., as compared to R-3.7 per in. that open-cell spray foam provides.
Rigid foam panels are created by shaping rigid foam insulation into stuff panels that are mounted on the woos of a crawl space. These panels typically (and ideally) use a closed-cell insulation design.
Like spray foam, rigid foam insulation offers higher R-value per inch than you get with fiberglass batts. It's also waterproof, stable (it won't compress) and able to stop air leakage when joints between rigid foam panels are taped.
Rigid foam insulation is the ideal material for insulating crawl space and basement walls. Performing this energy-saving upgrade eliminates the need for fiberglass insulation, and is typically part of the crawl space sealing (aka encapsulation) process.
Installation of rigid foam panels is often combined with sections of more expensive, closed-cell spray foam. The panels cover the walls, while the spray foam seals small cavities and areas where it would be difficult for rigid foam paneling to be properly installed.
When installed correctly, rigid foam panels will create a vapor barrier on your basement walls that will keep back water, water vapor, and humidity that could otherwise build in the basement and contribute to humidity levels and, subsequently, mold.
TerraBlock™ Insulation is made with 3/4" expanded polystyrene (EPS) foam insulation.
This insulation is specifically designed to provide a durable layer of insulation on your crawl space floor, while also providing a vapor barrier to hold back moisture.

Instead of insulating the crawl space at the walls and floors, many homeowners will instead opt to install fiberglass batt insulation on the crawl space "ceiling".
Insulating from the floor joist provides some energy savings by preventing some of the cold from the crawl space from permeating into the rest of the home. This insulation has the added advantage of providing sound-dampening properties, so that there is less noise upstairs as residents walk on the floor located over the crawl space.
While insulating the floor joists will protect your living area, your crawl space will remain as cold as ever during the winter months.
This becomes relevant to the homeowner as the utilities stored in the crawl space, including the water heater, hot water pipes, furnace, and air ducts are cooled in the unconditioned environment.
Locating these utilities in a cold environment will force them to work harder than ever -- which will cost you much more on your utility bills.
Instead, we recommend that you insulate the crawl space from the walls and floors -- protecting the entire space from the cold in the environment.
At Basement Systems, our Certified Dealers provide insulation products that are custom-designed for the crawl space. They seal as they insulate, are fully waterproof, and are versatile enough to be installed around obstacles in a potentially low-ceiling crawl space.
