Trusted Attic Insulation Company Near Reston, Sterling, Ashburn

We are Virginia's experts for installing attic insulation

Affordable upgrade. Cellulose insulation is often used in attics because it can be installed quickly and effectively with blowing equipment. Cellulose is super-green: It's made from recycled newspapers and treated for resistance to fire, mold and insects.

Upgrading attic insulation is a VERY popular energy-saving improvement because more energy (and money!) is lost through the attic than through any other part of the house.

What makes matters worse is improperly or poorly installing inadequate attic insulation. Existing attic insulation in many homes may be as minimal as R-19-- which pales in comparison to the recommended R-value!

Going through a cold winter with so little insulation is like wearing a t-shirt in a snowstorm. What your house really needs is the equivalent of a thick down-filled parka.

The U.S. Department of Energy recommends between R-49 and R-60 of attic insulation in Sterling, Leesburg, Ashburn, Fairfax, and other areas. That's at least a 16-in.-thick blanket of fiberglass insulation!

Before and After

Before

After

This Vienna VA home was being remodeled and had its interior frame stripped down to allow for installation of more modern insulation products. Our team started working in the attic before addressing the inside of the walls in the rooms below. Old insulation was removed and the attic was air sealed with Zyp Foam in order to control unwanted air flow in and out of the space. A new attic floor decking was constructed by our team along with damning/walls to hold in the Tru Soft Cellulose Insulation that would later be blown in. A zippered Attic Tent door cover was installed to properly seal up the attic door and control air loss from the rooms below. The final result for the attic was a thick layer of insulation and a more energy efficient top floor of the home. The floor/decking would allow for storage space and the ability to walk around the attic.

This attic in Arlington VA was previously treated by our team and had been filled with Tru Soft Cellulose Insulation. The homeowners decided that they needed to have a more cleared access to their HVAC and utility systems in the attic so they asked up to create a path. Our Production team was able to build a walkway from the attic hatch all the way to the HVAC unit in the attic.

After

This home in Marshall VA needed an upgrade to the attic insulation it had. The existing insulation was insufficient for the space and environment of the home and there was a lack of air sealing. Our production team removed the existing insulation and applied air sealing to the attic floor before blowing in Tru Soft cellulose insulation to properly insulate the many HVAC ducts and the rest of the attic.
Before

After

This homes attic had old insulation, open access air vents and an attic fan. This all added up to a lack of control over the space and temperature fluctuations that impacted the comfort for the homeowners in the living spaces below. We air sealed the attic with ZypFoam, sealed up the vents and fan and used SilverGlo insulation panels to cover many of the walls and other needed spaces in the attic. This will help control the space and reduce the loss of conditioned air from the living spaces below. Increased comfort and lower bills will be other nice results.
Before

After

This home was leaking conditioned air from the HVAC system into the attic, causing the temperatures in the living areas of the home to be uncomfortable. We cleared out all of the old insulation, air sealed the ceiling, and put in TruSoft Cellulose insulation to keep the attic functioning the way it was intended. In addition to the improvement in insulation, the material used will help to reduce and deter the presence of rodents in the attic.

Importance of Air Sealing and Insulating Attics

Larry Janesky explains that insulation is also needed in warmer areas. Insulation prevents heat transfer. It prevents hot air from being transferred to the outside in the wintertime, and prevents the attic's scorching heat from being transferred into the living areas of your home during the summer.

Air Sealing Goes Alongside Attic Insulation

DETAILS MAKE A DIFFERENCE!

Baffles keep ventilation channels open. Plastic spacers are installed between rafters in the attic to maintain a vent space beneath the roof surface after new insulation is installed.

Air sealing is a critical step when insulating an attic because sealing air leaks stops conditioned interior air from leaking into the attic. Comfenergy uses a variety of materials and techniques to stop this energy-wasting air leakage.

Installing baffles ensures proper attic ventilation. Sized to fit between the rafters in the attic, plastic baffles maintain a ventilation space between the attic's soffit vents (located along the eaves) and the ridge vent. Installing baffles before adding more attic insulation helps avoid damage from ice damming and excess moisture.

Old insulation can be reused, most of the time. As long as the existing insulation is not wet, moldy or overly compressed, it can usually be put back into place after the attic has been air-sealed and before new insulation is installed.
