    Ashburn Va Attic Wall Insulation

    This Ashburn VA attic underwent a full transformation.  After our Home Performance Sales Pro performed a no cost inspection of the home, it was determined that the attic space would benefit from air sealing, blown cellulose insulation and panel insulation used on this wall that was facing the sun for most hours of the day and required additional attention to be properly insulated.  The existing wall panel insulation was insufficient and was not air sealed.  Our production team installed the SilverGlo insulation panels and used ZypFoam to seal up the cracks in between.  This helped to create the best result to help improve the comfort ii the home and reduce the energy costs related to heating and cooling the home.

    Ashburn VA Attic Hatch Platform and Insulation

    This Ashburn VA home had a need for a full attic insulation project.  The rooms in the home below the attic were uncomfortable, the attic was not air sealed and the existing insulation in the attic was not performing as needed.  Our Home Performance Sales Pro Jon recommended removal of the old insulation so that our production team could air seal the attic floor and then blow in Tru Soft cellulose insulation.  Additionally Jon added the production and building of an attic landing where the access hatch to the attic was.  This would allow for people to access the attic and stand on the platform with a barrier between the insulation.  A hatch cover was installed with a zipper seal to keep conditioned air from escaping the rooms in the living areas below the attic.   Our production team constructed this and helped to create a more comfortable home and more accessible attic for the home owners.

    Home efficiency improvement in Leesburg

    These clients were interested in improving the overall efficiency of their home. They had uneven temperatures from room to room and poor airflow through the house. Don Calnen performed a home inspection and identified the need for improved insulation and air sealing in the attic. We removed the old insulation, installed several can light covers and then air sealed with ZypFoam. The knee walls in the attic were fitted with foam boards to seal and insulate before the rest of the attic was filled with TruSoft blown cellulose insulation.

    Leesburg VA Attic Insulation and Air Seal

    This Leesburg VA home was uncomfortable to the homeowners.  They called us to get help and our Home Performance Sale Pro Eric went out to perform a no cost whole home inspection to try and find a solution to their problems.   The attic had insulation that was not getting the job done.  The performance level of the existing insulation (otherwise known as R Value)  was less than what would be needed for the type of home and space in the attic along with the fact that the attic was not air sealed.  This meant that conditioned air made by the HVAC system was being allowed to escape from the rooms it was made to cool down or heat up, causing the HVAC system to run more and use up more energy.  Our production crew came and removed the existing insulation, then used Zyp Foam to create an air seal around the cracks and can light fixtures that accessed the rooms below.  They would then install Rock Wool insulation to cover the base of the attic and then blow in Tru Soft Cellulose insulation to fill the space to its needed R Value.  Shown here is the attic at the mid way point in the project when the existing insulation was removed and the air seal had been completed.  Then shown as after is the finished project with Tru Soft insulation covering everything.
