Notable ones were the Duke Johann Ernst during Bach's ti â¦ me in Weimar, Prince Leopold (Bach's patron while he was in Kothen) and the Leipzig council during the final years of his life. But not all his music was composed for his patrons.
Blow-in cellulose insulation has been around since the 1920âs and consists predominantly of recovered or recycled newsprint and/or corrugated cardboard, treated with a fire retardant. Three main types of blow-in cellulose insulation are used in residential application: loose fill, stabilized, and wall-cavity spray. Spray-in Foam Spray-in or spray-on polyurethane foam expands to fill cracks and voids to form a tightly sealed barrier.
In a cooling climate, a good blanket of attic insulation helps keep the house cooler and reduces the load on air-conditioning equipment. Most attics are insulated with blown-in loose cellulose (R-3.5 per inch), blown-in loose fiberglass (R-2.5 per inch) or fiberglass batts (R-3.2 per inch). Cellulose is recycled newsprint treated with a fire retardant. Fiberglass is just that--thin fibers of glass that trap air.
