One of the most common style of home that Racine Home Insulators, LLC retrofits with insulation is the 1-1/2 story home with a finished attic. This is a very common style in Racine and Kenosha.
The finished attic consists of separate sections that may require different sealing and insulating methods:
- The peak attic, located above the finished attic.
- The sloped roof or slanted ceiling wall
- Knee walls, between the finished attic and unconditioned attic space.
- Outer ceiling joists (floor), between the heated room below and the floor of the knee-wall
- Seal attic bypasses before insulating.
- Create an airtight and structurally sound seal in the joist space under the knee wall.
- When possible, insulate the slant wall with dense pack cellulose
- Insulate knee walls with dense pack cellulose or fiberglass batts covered with house wrap.
- When the knee wall area is used for storage, create a dam to hold back insulation and/or construct a cold storage platform to maximize R-value.
- Weatherstrip and insulate knee wall access hatch/panel to R19.
Once this work is done to the attic and knee-wall homeowners will notice a definite moderation of temperature of their upper level. This method of insulating also helps eliminate ice dams in this style of home.
