Insulation for Detroit Home
Cellulose, fiberglass and mineral wool are the among the most widely used home insulation options due to the fact that they are economical, familiar to most contractors and readily available. The ambitious homeowners even have the right to install some products with the right instructions and equipment.
Fiberglass is one of the most widely used and well known insulation options. Fiberglass is made of silica sand which is heated to a very high temperature in order to produce glass and then spun into micro-fibers. It is the most popular kind of insulation option on the market and it comes in tolls, batts and as a loose-fill.
Fiberglass batts can be installed in wall cavities and between floor joists in new construction. Besides, Loose-fill fiberglass can also be blown into attics, ceilings and wall cavities.
Fiberglass is quite an inexpensive material. It is very effective but it also poses some potential health issues. For example, most fiberglass insulation products sold in America are posted with cancer warnings. The microscopic glass slivers could break loose and be inhaled easily, thus lodging and irritating in the respiratory system. Reduced lung capacity and even cancer can be caused due to prolonged exposure.
Besides, formaldehyde-based binding agents produced standard fiberglass that creates vapors and this can affect both the installers and the home occupants. The Environmental Protection Agency classified Formaldehyde as a probable human carcinogen. Therefore, some manufacturers have introduced formaldehyde-free fiberglass insulation. Miraflex is soft and it is not irritating to the skin compared to formaldehyde. The advantage of fiberglass is that it doesn’t shrink and it will not burn. Besides, it will not attract insects. Standard batts for 2” x 4” wall cavities are rated at R-11 while high-density batts are rated at R-15. A builder can easily get away with cramming an R-19 bat for a 2” x 6” wall into the standard 2” x 4” wall in a new construction. However, it will not help if you have an existing house.
Cellulose insulation is mainly made of shredded, recycled newspaper and also some amounts of cardboard. It has a fluffy consistency. It can also be damp, sprayed or dry, into attics and wall cavities. Cellulose insulation is an insect repellant, mold inhibitor and fire retardant when it is used with boric acid. Cellulose has a standard R value of 3.2 per inch while blown fiberglass has 2.2 R value.
Blown cellulose insulation does not contain cancer causing fibers, even though it will produce some dusts during the installation. But it is much safer for both the installers and for the homeowners. Cellulose insulation is really the best option for people who are environmental friendly. This is because we are now using many tons of newspaper to insulate our houses and they would otherwise be dumped in the landfills. Although recycled glass is used for fiberglass production, it requires significant amount of electricity. Therefore, it just cannot compare with the performance of cellulose.
Rock Wool and Mineral Wool used to be the most common insulation options in America. Mineral wool is a fibrous insulation made of stone and iron ore waste from the steel making industry. Similar to fiberglass, it comes in blankets and it could be blown-in as a loose fill. Mineral wool is also moisture-resistant and so it can maintain its insulating properties even when it is wet. It is also heavier than fiberglass and cellulose. Mineral wool is a perfect acoustic insulator and it can go under temperatures of over 1800 degrees Fahrenheit. It has a higher R value per inch compared with fiberglass, while it is less than cellulose.
