At DMV Insulation, we recommend a comprehensive three-step process to enhance the insulation in your home's attic area.
Contrary to claims made by some companies, we do not always endorse removing old insulation unless it becomes damp, moldy, or contains contaminants. If needed, we can remove all old insulation and dispose of it, providing you with a clean slate to work with.
We first remove the old insulation to access the attic floor, enabling us to air seal the attic area effectively. Attic air sealing is a crucial step in maintaining a healthy and comfortable home in the DMV area throughout the year. We use low-pressure spray foam to create a tight seal, preventing air-conditioned air from leaking out of living areas and stopping dust, mold, and contaminants from seeping in. Attic air sealing also forms a moisture barrier, controlling humidity inside your home.
Once the attic area is tightly sealed, we proceed with the installation of your new, clean insulation. Our technicians evenly distribute the loose Sanctuary by Greenfiber insulation over the attic floor surface. During the installation, we ensure the insulation meets the recommended R-value for your area, typically an R-49.

At DMV Insulation, we employ cutting-edge air sealing techniques and products tailored to meet your specific needs:
Our skilled technicians use pre-mixed foam that requires no special equipment. This foam forms a thin, efficient layer on the attic floor, sealing gaps and ensuring airtightness.
In areas where precision is crucial, such as around light fixtures, we apply high-quality caulking to close gaps before applying the low-pressure foam. Our attention to detail guarantees a tight air seal in your attic spaces.

That depends on four things: the recommended R-value, your climate, the type of heating and cooling system you have, and the section of the house you plan to insulate. For the recommended levels of insulation, the U.S. Department of Energy publishes this map with the R-values they recommend.
It’s made of cellulose, which is a basic part of plants (think wood pulp). Our cellulose insulation consists of up to 85% post-consumer paper fiber. It also contains additives for fire resistance, and some insulation has been treated with boric acid for protection from pest infestation and moisture. What it doesn’t contain is also important: There’s no formaldehyde, asbestos or fibers from textiles, fiberglass or mineral wool in Greenfiber insulation.
We have a long list of fire safety credentials: Our cellulose insulation has a Class 1 fire rating from American Society for Testing and Materials E84 testing and is permitted as a fire block. It’s also manufactured to meet strict U.S. Consumer Product Safety Commission fire safety regulations, and all our products meet ASTM C739 and E84 tests.
Plus, we have a growing list of fire resistance–rated building assemblies, of both wall and floor and ceiling types, that are listed in the UL certification database. All our products are classified by UL and carry the UL mark on every bag. Bottom line: You’re safer with Greenfiber than without it or with any other type of insulation.
Nope. Accelerated aging tests (CAN/CGSB-51.60 M-90) performed on cellulose insulation have shown that there’s no noticeable degradation over time. In addition, Greenfiber offers a limited lifetime warranty, which includes the permanency of the fire-retardant treatment we use, for the life of the structure.
Where air goes, sound follows. Our sound-control quality is due to Greenfiber insulation’s density and its ability to fill any cavity since it’s easily blown into voids and gaps that could allow for sound transmission. When dense-packed or spray-applied into exterior walls, Greenfiber can reduce sound power by 60% and is especially good at blocking airborne sound from traffic noise, airplanes, radios, televisions and conversation.

You bet. Our insulation is ideal for providing additional R-value over existing attic insulation since it completely fills voids and gaps left open by other forms of insulation. It can also be installed in existing uninsulated exterior walls through various methods.
It will settle in attics until it reaches a stable density, as will other types of blown insulation. Coverage charts have already taken this into account, so it’s nothing to worry about.

We do not recommend the use of vapor barriers with cellulose insulation, except in circumstances of exceptionally high moisture levels, such as an indoor pool facility. Particularly in the Northeast, where summers are warm and humid, a vapor barrier not only is unnecessary but also can be potentially harmful. At Greenfiber, we warrant our cellulose insulation for the life of the building when installed by an approved Greenfiber insulation contractor.
