Hard to Insulate Areas

Many homeowners are incorporating designs or architectural features into their homes that pose insulation challenges, because conventional insulation; doesn't adhere well (or can settle over time); doesn't fit unusual cavities (batts are standard size); must be manipulated or compressed to fill unusual spaces (reducing R-value); or require extra finishing materials.

What's the problem?
  • Areas like arches, cathedral, domed or vaulted ceilings have limited space for insulation or make it difficult for insulation to adhere well (decreasing R-value and creating air leaks)
  • Many newer homes use steel framing which have "U" and "C" sections, double studs and non-standards stud locations that make insulating a challenge 
What can you do?
  • Consider a product which can: create an air barrier by filling all gaps; stick to surrounding materials; and deliver ideal R-value all in one step
  • Look for insulation like Icynene that's ideal for steel-framed homes, by expanding to fill all (even unusual) spaces and voids that exist between metal stud wall systems

    I am SO glad I decided to use Icynene to insulate the entire envelope of my house. We did a full-renovation, and the 100% air barrier has been fabulous. Ameri-spec tested our house for the federal renovation grant, and said we were more heat efficient than most of the new "green" homes going up on the west side. Icynene definitely contributed to the $3800 rebate we got.
