Attic Insulation Project in Winchester, VA
A home in Winchester, VA was experiencing unbearably hot top floors during the summer months. The master bedroom was the worst - sometimes, the homeowners had to sleep in the downstairs guest bedroom to escape the heat!
It came as no surprise to us that the attic had insufficient and almost non-existent insulation. It also had a vent that was directly allowing outside air in! It's no wonder that the rooms under this attic would be having these issues.
To fix this problem, we first air sealed leakage points with spray foam. We then blew in a thick layer of cellulose insulation through the entire attic. This attic is now a conditioned space and won't contribute to comfort/efficiency problems any more!

Can light leakage-Middletown, VA
This Middletown, VA homeonwer was complaining that their top floor was cold and drafty in the winter. Upon a full comfort and energy evaluation by Comfenergy, we determined one of the issues to be leaky can lights in the ceiling. Each can light is merely a 6" diameter hole that allows heated air to escape, and cold drafts in during the winter.
Rock wool can light covers lessen this leakage and also provide a necessary thermal and ignition barrier from the hot can light to protect against the possibility of fires.

Front Royal Wall Insulation - Dense Packing
This Front Royal VA home had a detached garage with living space above. The garage was often too hot in the summer or too cold in the winter. Our Sales Professional Pedro identified an opportunity to improve those issues by dense packing the walls with insulation. Our production team removed sections of siding before making hole in the plywood frame of the walls and then used tubes to blow i and pack the insulation into the empty cavities of the wall frame.

Front Royal VA Attic Duct Management
Sometimes it can be helpful to improve the existing infrastructure in an attic to optimize energy efficiency for our clients. in addition to air sealing and adding insulation, this Front Royal VA home had extra length in the HVAC duct system running through the attic. Although it was well insulated, there was excessive distance for the conditioned air to travel, making it harder to deliver at the intended temperatures. Our production crew shortened it in sections and created a platform and damning system to allow for walking and or storage in the attic near its opening. A new attic hatch was installed which can zip closed when access to the attic is not needed.
