What is “air-sealing”?
Air-sealing is basically draft-stopping – we want to eliminate any air movement between the conditioned space and the outside. The benefits of doing this are numerous and you may read more about those here: blower door testing page. The methods and products we use to achieve greater air tightness in buildings are many, and may include sealing all penetrations to the attic, dense packing walls with cellulose insulation, or sealing the rim joist with 2-part foam. We may need to remove window casings to seal the gap at the rough opening, or even replace a window.
- Setting up another project.We are finishing the basement, master bath, custom woodworking and many electrical upgrades for a couple just arriving from Sweden. Because they are energy conscious we did an energy audit and insulated the rim joists, walls and attic. European light fixtures were rewired to handle American connections and all bulbs were replaced with LEDs
- Basement improvements - We insulated, repaired everything. The basement was a mess. It was cleared, floors and walls grinded down and waterproofed and painted. The home was sold above the asking price in three days. (“ We love the basement” ) was the common comment.This project is part of our First Impressions department. The house was to be sold.
- Ceiling and walls are netted and dense-packed with cellulose. This eliminates vermin, mold, deadens sound transmission by 80% and reduces heat transfer 100% better than fiberglass. A house with all cellulose insulation can get a 5% deduction on their insurance since the home is fire proof.Ceiling and walls
