Spray Foam Insulation

Spray Foam Insulation Provides Superior Performance and Significant Energy Savings!

Spray Foam Insulation is a great alternative to traditional insulation such as cellulose and fiberglass batts. It comes in 2 varieties: Open Cell and Closed Cell. Both offer a superior Air Seal when compared to any other type of insulation, and controlling air flow needs to be a priority to make your home comfortable and efficient.

Spray Foam Insulation also provides a Superior R- Value (Resistance to Heat) when compared to traditional Insulation Materials:


R-Value/ inch

Fiberglass Batt


Blown Fiberglass


Blown Cellulose


Dense Pak Cellulose


Open Cell Spray Foam


Closed Cell Spray Foam

There is a lot of talk and confusion about the safety and durability of spray foam insulation. But here are some facts:

  • The Drying Co./ ThermalTec has insulated many schools and commercial buildings with the toughest standards: Kellam High School in Va. Beach; Tyler Hall at William and Mary College in Williamsburg; Virginia Commonwealth University basketball practice facility in Richmond; Brandermill Woods Retirement Home in Midlothian; and Rockingham Memorial Hospital in Harrisonburg- all insulated with spray foam insulation.
  • The U.S. Green Building Council has developed a Green Building Certification called Leadership in Energy and Environmental Design (LEED). The Drying Co./ ThermalTec is very proud to be the Insulation Installer for the first building in the State of Virginia to meet the newest Leeds 4.0 certification: The Children’s Hospital of the King’s Daughters in Virginia Beach. The insulation material being used is closed cell spray foam.
  • Spray Foam Insulation is a 2- part chemical and when the 2 chemicals are mixed and sprayed on the surface to be insulated, there is an “off- gassing” and precaution (usually leaving your home for 24 hours) needs to be taken. After the spray foam is cured, it is non-Toxic and actually a better insulation material for the health of your family. Spray foam acts as an air flow barrier, thus reducing moisture movement and the growth of mold and mildew which cause wood rot.
  • The U.S Department of Energy has shown that most homes lose over 60% of their energy through attics and crawl spaces. Homes that are insulated with spray foam lose at least 50% less air than homes that haven’t. This saves you money on your energy bills and the insulation materials cost are a tax credit!

Typical Spray Foam Uses:

Attic Duct Work:Spray Foam Duct Work

A vented attic is the worst possible place for ducts. It can be 125°  in summer when the air inside your duct is 50°, and 30° in winter when the air inside your duct is 80° – these are hostile conditions to making your home comfortable and efficient. Spray foaming over top of existing insulation air seals any leaks that prevent air from ever reaching its intended destination. In
addition, the air produced in your HVAC unit is allowed to travel to its intended destination without losing heat in winter and cool air in summer. The result is more comfortable rooms, lower fuel/ energy bills, longer HVAC unit life.

ALSO- If your Home qualifies (All Electric)- You can get a rebate from Dominion Power for making your air delivery system more efficient: https://www.dom.com/residential/dominion-virginia-power/ways-to-save/energy-conservation-programs/duct-sealing

Spray Foam Insulation on Attic Rafters

Insulating Your Attic from the Rafters:

Spraying either open or closed cell spray foam on the bottom of your roof deck and gable end walls creates a super air tight cap on the top of your home that keeps warm air in during the winter and stops heat from radiating in through the hot roof in the summer. The result is a more comfortable house with lower energy bills and less dust.

Spray Foam Air SealAttic Air Sealing:

Warm air rises in your home due to a phenomenon known as “The Stack Effect”. Neither fiberglass batts, blown fiberglass, nor blown cellulose can prevent this air loss through your attic without air sealing. Spray foam around any penetration or gap will make your home more efficient and allow the insulation to work better.

Rim and Band Spray FoamRim Joists:

The rim joists is the perimeter of your house frame along the exterior of your house. The joints and gaps allow for a lot of air leakage into your conditioned living space. This area is seldom insulated and when it is, it is usually fiberglass batts which do nothing to prevent air flow. Expanding spray foam on rim joists and over sill plate seals air leaks from outside and insulates this important area of your home.

Crawl Space Wall Spray Foam

Crawl Space Walls:

Insulating crawl walls with expanding spray foam is a great alternative to rigid foam
boards and most especially, fiberglass batts under your floors. Removing the fiberglass from under your house and then insulating the crawl walls air seals the porous block and any gaps, adds insulation, and along with a proper vapor barrier, moves the thermal barrier of your house from under the floor, to the crawl walls. All HVAC and Duct work are now inside the thermal barrier and operate more efficiently- saving you money on energy, and making the air you breathe cleaner. All plumbing is now inside and chance of freezing pipes is very slim. There is less humidity in your crawl space, your house is more comfortable and you have lowered your energy bill.
