Comfenergy Before & After Photos

This Sterling VA attic received several steps and services to improve the comfort and energy efficiency of the home, one of which was having the HVAC ducts running through the attic encapsulated with spray foam.  The metal ducts had been susceptible to temperature issues when the attic would heat up or cool down depending on the time of year and weather outside.  When the attic was hot and cold air was passing through the ducts, the conditioned and cooled air would not reach the rooms it was intended to before safely.  When it was cold and there was heated air passing through, the cold ducts would work to reduce the heat of that air.  Encapsulating the HVAC ducts with spray foam keeps the air inside safe and helps to reduce the energy cost to create more heated or cooled air.  

A homeowner in Goldvein, VA needed some insulation in his home. Heat moves from more to less - out of a building in winter and into a building in summer. Insulation is needed to slow this heat flow down.  Closed cell spray foam adheres to all surfaces, expands in place, and air cannot pass through it. It is superior insulation with an R-value of 6.3 per inch. Closed cell spray foam weighs 2 lbs per cubic foot and special equipment is used to spray it. 

Top wall plates allow heated air to escape from your home during something called the "stack effect".  This contributes to higher than necessary utility bills, draftiness in the home, and dusting too often. The following before/after pics show how Comfenergy seals these leaks using one part spray foam.

Metal (and brick) flue pipes and chimneys can get very hot when furnaces, water heaters, and fireplaces vent through them.  Insulation should not touch these assemblies due to the possibility of fire in the attic of the home. Comfenergy wraps these flues and chimneys with rock wool fire resistant insualtion before blowing new TruSoft cellulose insulation into your attic.

In the summer, your roofing really heats up! Sometimes up to 150 degrees. This heat radiates down from the underside of the roof and into the attic. The heat from your ceiling radiates down into the rooms, heating the air and all the objects in the room. This makes your air conditioner work harder and for longer and makes your upstairs level uncomfortably hot. Stefan's Radiant Barrier can help. It is installed across the bottom of the rafters. Resembling foil, the barrier reflects much of the heat and keeps the attic much cooler.
