What is Insulation R-Value
The R-value of insulation measures how well insulation resists heat flow. The higher the R-value means the more resistant the insulation is to heat flow. R- value is measured per inch and ranges from R-2.2 to R60. R-values vary based on type of insulation and brand of insulation. At Danner Spray Foam we use 2 lb. closed cell spray foam which is 7.1 R-value per inch.
Factors When Choosing Insulation
- Type of Insulation: spray foam (closed-cell or open-cell), fiberglass (batts or loose-fill), cellulose (loose-fill), foam board.
- Structure Needing Insulated: home, business, barn, etc.
- Areas of Structure Needing Insulation: walls, attic, crawlspace, floors
- Location Weather: city & state to determine insulation thickness.
2 lb Closed Cell Spray Foam

At Danner Spray Foam, we specialize in 2 lb closed-cell spray foam because it delivers better value: often lower total cost than open cell, higher R-value per inch, and a dense layer that blocks air and moisture to control condensation and drafts.
It leaves a
clean, durable finish and installs efficiently in
homes, commercial buildings, and ag shelters. Expect consistent cavities, fewer callbacks, and
lower operating costs over time.

Why Spray Foam Beats Fiberglass
Fiberglass is common because it’s cheap, easy to find, and simple to install. But spray foam brings more benefits for most homes: it seals air leaks, controls moisture better, and keeps temps steadier—so rooms feel more comfortable and energy use drops.
A big worry with fiberglass is mold. While the glass fibers themselves don’t feed mold, fiberglass traps dust and dirt. Add moisture from leaks, condensation, or high humidity—and poor roof/HVAC venting—and mold can grow on that trapped grime. Because insulation is hidden in attics, walls, and crawl spaces, you might not see it right away.

Signs fiberglass may have mold:
- A musty smell
- Dark or blotchy discoloration on the insulation
- Health symptoms like allergies, headaches, coughing, sneezing, stuffy nose, or skin rashes
