Attic Insulation installed in Reston

Affordable upgrade. Cellulose insulation is often used in attics because it can be installed quickly and effectively with blowing equipment. Cellullose 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, and other areas. That's at least a 16-in.-thick blanket of fiberglass insulation!

Before and After
  • Attic Insulation in Sterling, VA
    Before

    After

    A homeowner in Sterling, VA called as their house was hot in the summer and cold in the winter and wanted to make their home more comfortable all year.   We air sealed the attic floor with one part foam spray, then installed attic decking on the floor with plywood. We created plywood "dams" to keep the future cellulose insulation in place and off of the attic floor decking.  Finally, we created an attic hatch cover that was made o 4" thick SilverGlo foam boards, and blew in TruSoft cellulose insulation throughout.  The result the homeowmer will be warmer in the winter and cooler in the summer.

Yet, the after pics are hiding the fact that the attic is completely air sealed and the decking rests on an R20 foam board!

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.
