Air sealing the attic floor in Wilmington, DE
Here you can see how Dr. Energy Saver uses orange Zyp expandable foam to seal cracks and holes in the attic floor. This is necessary to ensure none of the air from the rooms below leaks into the attic. If you are wondering why this matters imagine what would happen if a hot air balloon had a whole bunch of holes in the top - hot air normally rises and fills up the balloon, which then expands and eventually lifts off the ground. But if there were holes the balloon wouldn't hold the air in and would never fill up. This is just like the air you pay to heat and cool in your home. You want to keep that conditioned air inside the house, not let it escape to the outside. This is why proper air sealing is so important.
Re-routing Bathroom vent duct in Wilmington, DE
Often in the past building contractors simply terminated bathroom ducts in the attic. But this really wasn't a great idea since all that heat and moisture are sent straight into the attic where it condenses, forms moisture, rots the rafters, and can cause wet spots to appear on ceilings below. Dr. Energy Saver recommends venting all bathroom fans, kitchen hood exhausts, and clothes dryers directly to the outside. The worker in this picture is cutting a hole through the roof deck to install proper termination of this bathroom exhaust duct. The fixture on the roof will be thoroughly sealed to prevent waters from coming seeping through.
Wiring Penetration in Wilmington, DE
Air can escape into the attic through small holes in the top plates of walls where wires go through. These holes are found all over the house and can add up together for a lot of air leaking and drive up the cost of energy bills. To stop this from happening, we seal these holes with Zyp™ expanding foam.
Penetrations in Wilmington, DE
Sealing holes in top plates through which plumbing and electrical wiring pass is an essential practice for maintaining energy efficiency and preventing the loss of conditioned air in buildings.
Top plate gap in Wilmington, DE
This gap is created during the construction of the walls that allows one to see right down inside the wall cavity from the attic. These spaces between the drywall surfaces of the adjacent rooms can act like a chimney, allowing conditioned air to be sucked in through electrical outlets, switches, ethernet and TV cables, plumbing and drawing them up into the attic. That's an unnecessary loss that can be solved by simply sealing these top plate gaps. This one is unusually wide.
Holes for dense packing insulation in Wilmington, DE
These holes had to be cut into the ceiling in order to insert the tubes which blow the insulation tightly into the spaces between the floor joists of the rooms above this garage. Once the insulation has been installed the drywall plugs are finished and you never know the holes were ever there.

Out with the old insulation in Wilmington, DE
Over time dirt, debris, dead insects, rodent and bird dropping accumulate in the fiberglass. Since new cellulose insulation will be installed we simply remove and discard the old fiberglass since we want a clean attic floor to do the air sealing properly.
