Comfenergy can improve the comfort of your home with our insulation improvements

  • Rigid foam insulation comes in large panels of varying thicknesses. It’s the best insulation to use on basement and crawl space walls because it doesn’t absorb moisture or attract mold.
  • Tru-Soft™ cellulose insulation is made from recycled newspaper treated to resist combustion, insects and mold. It’s often blown into attics as an insulation upgrade, but it can also be blown into wall and floor cavities.
  • Injection foam is specially formulated for insulating wall cavities, cathedral ceilings and other enclosed spaces. With excellent flow and fill characteristics, it can be used where there’s no insulation or where existing insulation isn’t performing adequately.
  • Spray Polyurethane Foam (SPF) is a two-part, closed-cell spray foam with many uses. It expands when applied, sealing air leaks while also creating an effective thermal barrier. It’s often used in attics and basements.

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.

Home insulation in Sterling and throughout Northern Virginia slows the flow of heat to save you and your family some money.

As a full-service insulation contractor, Comfenergy provides expert home insulation services to improve areas such as walls, crawl spaces, basements, and garages in Northern Virginia.

    The workers the day the job was done were very polite and considerate. But the one thing I would recommend is they clean up a little better. had they brought a leaf vacuum, they could have gotten all the little bits of insulation they left every where, and I wish they had cut the Styrofoam blocks on top of something as now I have tiny shreds of it in my grass and it will not biodegrade.
