Before & After Photos

This Lorton, VA homeowner was looking for ways to lower their utility bills.  Comfenergy found a ton of air leakage in the attic allowing the heated and cooled air to leave the home.  This before and after pic set is showing how we air sealed around an air duct that went into the top floor. By closing this gap, we prevent any air travelling between this space. 

This set of before and after photos shows the difference between light, fluffy fiberglass insulation and new TruSoft cellulose insulation in an attic.  Here are the differences you may not know:

1. Fiberglass is more susceptible to something called "wind washing".  In a vented attic assembly wind can blow around in the attic and it can easily pass through the fiberglass.   TruSoft cellulose packs tighter and it's harder for wind to travel through it.

2. Rodents and insects LOVE fiberglass.  They nest in it and make it home.....right above your head.  TruSoft cellulose is chemically washed with a liquid borate which deters rodents and insects by irritating their respiratory system.

3. TruSoft cellulose has a higher R value per inch than fiberglass.

4. TruSoft cellulose is also less succeptible to flame spread than fiberglass as well.....

This Arlington, VA homeowner was remodeling their home and wanted to use spray foam for their basement. Comfenergy recommended a closed cell spray foam without a thermal barrier for this project.  This type of spray foam was used for its ability to be a vapor barrier.  Also, the spray foam was being covered up by drywall, so there was no need for a thermal barrier.

This Arlington VA home has a design feature commonly referred to as a cantilever, where a portion of the home hangs out wider than the rooms below it leaving open air at the lowest point of the floor.  If that flooring is not insulated, the external air temperatures can impact the living space inside of the home.  Pictured here you can see Ariel Campos removing the external base of the cantilever and applying spray foam inside to act as insulation.  This will keep outside temperatures from impacting the home and will contribute to a more comfortable living space.  

This Arlington VA home had a large cantilever extending beyond the footprint of the foundation.  A cantilever can add square footage for upper floors compared to the foundational floor by extending outward but the design often leaves homeowners experiencing comfort issues.  An uninsulated or unsealed cantilever can allow external air and temperatures to come in through the rim joists of the home and will often result in colder or hotter than wanted floors.  We remove the panels framing the bottom of the cantilever and use spray foam to seal up and insulate.
