Spray Foam Insulation installed in attic that has HVAC Ductwork

ATTIC SOLUTIONS – CREATING A LARGE IGLOO COOLER

For a typical home, most of the energy loss is through the attic.   In the Augusta area, our attics in the Summer are between 120-150 degrees placing a large burden on your Air Condition System (HVAC).   If your HVAC ductwork is located in the attic, you are losing efficiency from normal ductwork leakage and from the taxing impact of the extreme temperatures on your ductwork.

Our approach for insulating attics is definitely different from traditional insulation methods.   We recommend closing all the vents in the attic, removing the existing insulation from the floor of the attic and installing Open Cell Spray Foam Insulation in between the rafters and on the walls of the attic.   Open cell spray foam rapidly expands filling in all the nooks and crannies in the attic rafters and walls – establishing an Air Barrier between your home and the outside world.  We are actually creating a large igloo cooler in the attic – resulting in moderate temperatures that are within 10 degrees of the living space – resulting in temperatures in the 80s in the attic during the Heat of the Summer!!!

We eliminate the extreme temperature burden on the house, improve the comfort and improve the indoor air quality.  We keep the Bad Air Out of the house and the Good Air In the house.  The Bad Air is the hot humid, pollen, allergens filled air in the summer and the cold air in the winter.  The Good Air is the Conditioned Air in the Summer and the Heat in the Winter – also known as the Expensive Air – since you have already paid for it.  We also improve the indoor air quality of the home by removing the old funky insulation from the floor of the attic.

 

Before: Traditional Crawl Space with debris, old plastic and vent

CRAWL SPACE SOLUTION – ELIMINATING THE HOLE UNDER THE HOUSE
The crawl space located under the house is also an area with a lot of energy loss – 35% on a typical home.  We have two different solutions for the crawl space.

If you have HVAC ductwork located under the house, we recommend creating a clean, insulated, encapsulated crawl space.  We clean away the debris from under the house and grade the dirt on the crawl floor.

After: Insulated Sealed Crawl Space – Closed Cell Spray Foam on walls and 15 mil plastic on floor

We then install a heavy duty 15 mil plastic vapor barrier on the crawl floor.  We overlap the seams by at least 12 inches and tape the seams with a specialty tape.  We extend the vapor barrier up at least 6 inches on penetrations and secure the vapor barrier with specialty tape.  We spray Closed Cell Spray Foam Insulation on the perimeter walls of the crawl space as the crawl space insulation.  This Clean, Insulated Sealed Crawl Space system puts the crawl space within the building envelop – eliminating air leakage from the living space and leakage from the ductwork.

If the HVAC ductwork is not under the house, then we recommend installing Closed Cell Spray Foam Insulation on the crawl space ceiling as the crawl space insulation.  We first remove all the existing fiberglass batt insulation from the crawl ceiling – usually some of it is dangling.  We then spray Closed Cell Spray Foam between the floor joist onto the subfloor creating a moisture retarder and an air barrier.  We eliminate the moisture drive and drafts coming from the crawl space – improving the energy efficiency, comfort and indoor air quality of the home.

In summary, there are two approaches for insulating your crawl space.  Crawl space encapsulation is typically more expensive but provides the additional benefit of creating a clean space and keeping the air leakage from HVAC ductwork inside the building envelop.  The other approach of installing spray foam directly to the subfloor is more cost effective and is the preferred method when the HVAC ductwork is not located in the crawl space.  Both approaches are going to make the home more comfortable and energy efficient.

Preparing to install Wall Injection Foam in Brick Home

EXISTING EXTERIOR WALL SOLUTIONS – FILLING IN THE VOIDS AND REDUCING SOUND TRANSMISSION
Walls and windows represent about 15% of the energy loss on a typical home.  Since it is a lower percentage of energy loss, we usually focus on the attic and crawl space first.  If your home has significant draft issues from the walls or your walls have insufficient or no insulation, we can install Wall Injection Foam into the walls.

Installing Wall Injection Foam in Home with Lap Siding

Wall Injection Foam is a non-expanding foam that can be installed through the exterior siding/brick or through the interior drywall.
We can install behind Vinyl Siding, Wood Siding, and Hardiboard and through Brick mortar joints.   We prepare the wall space either removing the existing siding or drilling a hole in the mortar joints.  Wall Injection Foam fills in all the voids eliminating drafts and reducing sound transmissions.  We plug the holes and reinstall the existing siding.  Wall Injection Foam will improve the energy efficiency and comfort of the home.
