Density: Mineral wool insulation has superior sound-deadening properties. On the other hand, it's less expensive than natural alternatives like sheep's wool insulation. A wool fiber's chemical complexity makes it resilient and elastic. There is also less waste with fiberglass insulation. Each of these options have different qualities and attributes that may inform your choice of materials. The higher the R-value, the better the material is at resisting the flow of heat. According to the Home Depot Web site, UltraTouch denim insulation retails for $6 per roll (16 inches by 48 inches or 41 centimeters by 122 centimeters), while Owens Corning fiberglass insulation costs $3.15 for the same size roll. Wool fiber properties yield a longer life than man-made fibers. The better the material is at resisting the flow of heat, the less energy you use. The thermal rating of insulation is referred to as the R-value and the higher the R-value the greater the thermal performance. The Department of Energy says that the average fiberglass contains 20 to 30 percent recycled material, while rockwool contains 75 percent recycled content, making it a more eco-friendly choice. . Fiberglass insulation costs between 25 and 50 percent more than Rockwool. With mineral wool, the fibers are much shorter, so in order to keep the batts in one piece, they have to be packed to a higher level of density. A comparable R-value for rigid foam costs roughly $10.

Despite their age-old popularity, both fiberglass and mineral wool insulation can lose their efficacy over time, meaning replacement is required in just a few years. Generally, Rockwool will be functioning for longer than fiberglass and the higher initial cost might be money well spent in the long run. It's comparable to fiberglass batts, but denser, which helps to dampen sound. Hi Melissa, The performance of the insulation really depends on the R-value.An R2.0 Greenstuf Polyester Batt and an R2.0 Pink Batt will provide the same thermal performance. Rockwool is denser and does a better proofing job. Cost: Fiberglass insulation costs 25 to 50 percent less than mineral wool. Fiberglass insulation typically costs about 50 cents per square foot, while Rockwool costs around 72 cents. Mineral wool is composed of 70% of recycled content, as compared to fiberglass insulation which is composed of only 30% of recycled content. In the guides, the reasons for insulating each area are covered along with the recommended R-value of insulation for your climate zone. If the budget is slim, he opts for blown-in fiberglass and dense-pack cellulose, but even then, he uses spray foam under the roofline. When comparing blown-in insulation, both fiberglass and cellulose are nearly identical in price, both costing around $0.70 to $0.80 per square foot for 6 inches of insulation.
