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 home in West McLean, VA had some attic insulation, but it was old, damaged fiberglass. The lack of proper insulation, especially during the hot summer months, was causing uncomfortable temperatures on the third floor as well as sweating duct work that was causing water damage. Luckily, Comfenergy has the perfect solution for this situation!

We removed the old insulation and made sure any points of air penetration were sealed. Then, we installed a blown-in cellulose insulation solution. 

We removed the old, traditional bat style insulation, air sealed the space with ZypFoam and installed Foamax insulation panels on the walls and roof of this attic.  This helped make the floor space in the attic useable and made the attic a fully conditioned space unimpacted by outside temperatures.  

Even a well insulated attic can get cold in the winter or hot in the summer.  That means that anything else in the attic can react to those temperatures.  HVAC ducts with cold air travelling through them in the summer or hot air travelling through them in the winter can be impacted by the attic temperatures.  Properly insulating these HVAC ducts and burying them in insulation can help.
