Home Insulation Contractors in Virginia!

You don't need a degree in thermodynamics to know that heat always spreads out to fill in where it is depleted.

In the wintertime, heat moves naturally from inside to outside. During hot summer months, heat "wants" to go the opposite way, moving inside the house to make spaces uncomfortably hot. Improving your home insulation will help slow the flow of heat to save you and your family some money, while keeping everyone comfortable.

Dr. Energy Saver provides expert home insulation installation services to improve wall insulation, crawl space and basement insulation, garage insulation and attic insulation in Alexandria, Fairfax, Springfield.

Thickness counts. The more insulation you install with the highest R-value possible, the greater energy savings you'll enjoy.

The more R-value, the better. There are many insulation materials, but all types of insulation are measured according to their resistance to heat flow, or R-value. Fiberglass batt insulation, for example, has an R-value of about R-3.6 per inch while rigid foam insulation can range from about R-4 to R-7 per inch. To achieve the higher "target" R-values recommended by the U.S. Department of Energy, it's necessary to install thicker layers of insulation.

Correct insulation installation is critical. For any type of insulation to achieve its rated R-value, it must be properly installed. When insulation is compressed, moist or installed with gaps or "voids," its performance drops significantly.

Spray foam seals and insulates. Conditioned air from the living space below can leak into the attic through numerous gaps around wiring and plumbing lines. Dr. Energy Saver uses spray foam to seal these openings.

Insulation and air-sealing go together. Sealing leaks in the "building envelope" is an important energy-saving step that should be done along with any insulation upgrade. Without effective air-sealing, heat can move by convection through most types of insulation, nullifying its energy-saving value.

It's very important to air seal leaks before installing insulation. This is especially important before installing new or additional attic insulation in Virginia. Existing insulation often needs to be moved or shifted out of the way in order to uncover attic air leaks.

Dr. Energy Saver can also perform a blower door test, as part of our home energy audit, to discover spots where air and heat are leaking into an attic.

After detection comes correction. Dr. Energy Saver uses the most up-to-date materials including sealants, caps to fit over can lights, and different types of spray foam. We make sure not to overlook any possible air leakage!

The "best" insulation depends on installation requirements. There's no such thing as the perfect insulation. Because of handling, installation and performance characteristics, one type of insulation is likely to perform better than another in a given application. Insulation costs also vary. 

Dr. Energy Saver has the experience and expertise to recommend and install the right insulation for the application. We aim for cost-effective, top-performing insulation.
