Spray Foam Insulation

Here at Virginia Foam Insulators we use only the highest quality spray foam insulation to work on projects such as retrofitting, crawl spaces, attics, and new construction. We take pride in our work, and make sure that we leave your home cleaner than we found it. Our projects in the Lynchburg, Roanoke, Charlottesville, and Richmond areas have helped homeowners for over 10 years!

Crawl Spaces

Within crawl spaces are one of the most problematic areas of the home in regards to having issues with moisture. They're within the foundations, and exposed to the dirt; if there's been rain recently it will be damp in your crawl space. Summer is even worse with its heat making it even muggier. This moisture is a breeding ground for mold and mildew in your home. Notwithstanding other issues such as pests and up to 30% of a home's energy loss.

Remove the existing insulation and apply a minimum 10 mil polyethylene vapor barrier (this is thick enough to allow you to walk around on it without puncturing the membrane) on the floor of the crawl space and glue the edges up the crawl space walls at least 6 inches above the outside grade.

We then close and seal all vents to the crawl space with rigid foam boards. If a combustion appliance such as a gas or oil furnace is present in the space, a dedicated air supply may be necessary.

Finally, we apply at least a 2 inch average of Closed-Cell Polyurethane Spray Foam to cover the seam of the vapor barrier as well as the crawl space walls and vents. A 2 inch average of Closed-Cell Polyurethane Spray Foam is also applied to the rim joist and band board as crawlspace insulation.

By using at least an average of 2 inches of closed-cell foam the homeowner gets an air and vapor barrier that eliminates the intrusion of cold and warm air through the crawl space walls while the polyethylene vapor barrier prevents the intrusion of naturally occurring moisture and pollutants that are present on the ground.

Remove the existing insulation and apply at least a 2 inch average of Closed-Cell Polyurethane Spray Foam to the crawl space ceiling. All ductwork and piping should be sprayed to prevent heat loss and to avoid freezing in the winter.

By using at least an average of 2 inches of Closed-Cell Polyurethane Foam the homeowner gets an air and vapor barrier that eliminates the intrusion of cold and warm air through the floor as well as the intrusion of naturally occurring moisture and pollutants, that are present on the ground and that get sucked up into the home because of the homes stack effect.

In many locations it is now code to have a minimum of 6-8 mil polyethylene vapor barrier installed on the floor of a vented crawl space so as to also help against the intrusion of moisture and pollutants from directly below the home.


Insulating your attic with spray foam insulation can help keep you cooler in the summer, warmer in the winter, and prevent issues with excess moisture and pests. Most homes built before 1970 have inadequate insulation.

Existing Home Insulation Services

Inadequate insulation and air leakage are the primary causes of energy waste in most homes costing American families $100s of millions every year in higher energy bills. If your home was built before 1970 chances are you have little or no wall insulation installed. Even homes built in the last 10 years can suffer from significant air leakage as state and local requirements for insulation do not address the amount of air leakage a house has but rather just the R-value of the insulation required in the walls and attics.

At Virginia Foam Insulators we can insulate your existing home's walls using the latest approaches and insulation materials to save you money as well as make your house feel more comfortable. At Virginia Foam Insulators our goal is to make your home feel warmer in the winter and cooler in the summer. We accomplish this by not focusing on the R-value (learn about the R-Value myth) of your insulation, but rather by promoting and installing products that stop unwanted airflow into and out of your home.

To get the simplest impact of insulation, customers are encouraged to install Blown-In Fiberglass. This product is cheaper than spray foam insulation but will also provide some energy savings. Homeowners will notice a significant improvement in their climate control when insulation is installed. While this less expensive measure will show homeowners the benefits of insulation, the product does not create a seal at the edges and, as insulation compresses over time, gaps can form at the top of the wall cavity.
Install Open-Cell Spray Polyurethane Foam into the wall cavity. As this foam rapidly expands within your walls, it covers and closes all cracks to create an air-tight seal. As the foam expands to fill all gaps and dries in place, you can be sure it will not compress, melt or fall away, giving you a more comfortable home for years to come.

New Construction

When building your new home, Virginia Foam Insulators can provide tailored insulation to insure that your home stays cool in the summer and warm in the winter.

Install the Blown in Blanket (BIB), also known as the Mesh Netting & Blown Fiberglass, in the wall cavity. While polyurethane spray foam is ideal, our BIB insulation system fills all crevices and areas not normally filled with standard batt insulation, thus creating a more complete barrier to heat and cold, in addition to reducing noise transfer. Improve your home's heating and cooling loss no matter how thin your budget with this practical solution.
By spraying at least a 1 inch average layer of Closed-cell spray Polyurethane foam between the wall studs and then overlaying the foam with Fiberglass, you create what is known as a flash & batt system. The idea behind the system is to fill in the gaps with cheaper material and use the more expensive spray foam sparingly for sealing and balancing out the code requirements. When these two materials are installed together, they get better results than either would on their own.
Open-Cell Polyurethane Spray Foam is a cheaper way to get the full seal you need. Upon spraying, this foam will expand up to 150 times its liquid volume, filling every crack and crevice of your wall cavity. After this process is complete, the excess foam is shaved off the studs, leaving a flat surface over which dry wall or other material can be applied. Providing a more efficient process than the Flash and Batt insulation system, this method gives the full seal you require for less.
Install a 2-inch average of Closed-Cell Spray Polyurethane Foam to the wall cavity. This highly dense material will expand up to 30 times its original liquid volume inside your wall, adding an R-value of 6.3 per inch. It fills in all the nooks and crannies like Open-Cell foam, but also provides an air-barrier, vapor barrier, and enhanced structural integrity. Closed-Cell Polyurethane Spray Foam is the most expensive insulation option, but presents the homeowner with the best insulation performance available.
