Building Science researchers have long known that energy efficiency starts with tight construction. Even in the finest construction, hundreds of seams and holes are created during the building process, allowing air to escape.
There are many paths through which outside air moves into your home and inside air escapes out of your home. If the holes in a typical home were gathered together in one spot, they would create an opening of over 400 square inches. That’s like leaving a window in your home open all year long, during the hottest and the coldest days of the year!
That air leakage can cause frozen pipes, uncomfortable drafts, and high heating and cooling bills. Eliminating these sources of air leakage through effective sealing during the construction process is the single greatest impact you can have on your home’s performance.
D.R. Nelson Energy Seal Service®
The D.R. Nelson Energy Seal Service® improves your home’s insulation performance by eliminating excessive air leakage. Our unique air sealing service stops that air leakage by our strategic applications of sealants during two critical stages of the construction process. If your home is built without our sealing service, many sources of air leakage are inaccessible, so our skilled technicians must get access to your home at two critical times:
First: Energy Seal 1
At the Rough Frame stage, we seal the exterior surfaces including all sill plates, bond joists, top plates, sheathing holes, electrical penetrations, mechanical penetrations, plumbing penetrations, overhangs, and dozens of other problem areas.
Second: Energy Seal 2
After Drywall is hung, we seal around the edges of the openings made for electrical outlets, plumbing fixtures, and other holes in exterior walls and ceilings.
By tightening up the “envelope” of the home, we limit the amount of air and moisture that can migrate into exterior walls and attics. The D.R. Nelson Energy Seal Service® ensures that your home will perform at peak efficiency. As a result, the homeowner will enjoy a cleaner, quieter, draft-free home and save up to 25% on their heating and cooling bills.
