Spray Foam Insulation Photo Album: Reston Virginia Spray Foam Insulation in Attic

This home in Reston Virginia had issues with humidity, uneven temperatures. After calling us to see if we could help, our Home Performance Sales Pro Carl was able to find several things to address. The existing insulation was thing and even none existent in some areas. There were bathroom vents moving humid air into the attic and the HVAC duct system was leaking air. All of this lead to uncontrolled air flow and high energy bills for the home owners. Our production team removed the existing insulation along with evidence of unwanted guests in a birds nest. The attic was cleared and then air sealed before having spray foam insulation used to insulate several areas of walls and all of the HVAC ducts. Walkways were built to allow access to different areas of the attic and damning walls were put up to hold blown insulation in place. Our team also wrapped chimney vents and put in new exhaust fan vents to the outside of the home.

Poor insulation

Thin insulation serves no purpose. These HVAC ducts had tears in the wrappings and were allowing conditioned air to leak.

Uninsulated walls

These walls had no insulation and allowed for outside temperatures to impact the temperature inside of the attic.

Poor insulation

Several inches of insulation should be in place to help deliver the proper R value.

Thin insulation level

Thin insulation is like wearing a jacket that has holes in it.

Can Lights and This Insulation

Each of these can lights presents and opportunity for conditioned air to escape the rooms below and leak into the attic. This can lead to high energy bills. We will air seal around them and prevent the air loss.

Old Insulation and Pests

Traditional, fiberglass insulation is often used by rodents and birds to nest. Once removed and cleaned, we use Tru Sof cellulose insulation which is treated with a chemical deterrent.

Air Seal and Spray Foam

The small cracks and gaps in the attic surface were air sealed with Zyp Foam. The walls and HVAC ducts were covered with spray foam insulation.

Spray Foam Attic

In addition to its insulation value, the spray foam helps to seal up any areas where air may have been able to move.

HVAC Duct Encapsilation

sealing the HVAC ducts means the air inside will not be travelling through a hostile environment on the way to the rooms it is intended to heat or cool. More efficient delivery of that air will increase comfort and reduce energy use.
