Our choice of wall insulation is Rockwool; it is sound proof, water proof, rodent proof, and fire retardant. (Our energy rater reminded us recently of a seminar where a flame is pointed directly at the product for the entire day with no signs of burning.) It has less dust and irritants than fiberglass, and is cut with a bread knife when installed. We used the product for the first time when building our zero energy home in 2015, and can verify its effectiveness. The exterior walls of the carriage house consist of a sandwich of R15 + R23 + R15 = R53. The 2x4 interior walls will also be insulated with R15 for added privacy and comfort.
The insulated envelope is one of the most important systems in a building. Proper air sealing and insulation are necessary. Regardless of the product used, air sealing and insulation must be meticulously installed in order to protect the building from moisture intrusion, which can lead to mold, rot and indoor air quality issues.
The photos depict half the quantity of insulation used in the building. Many thanks to Quality Hardware in Hudson Falls for acquiring the product for us, at a reasonable cost.
