San Antonio Roofing: Article About Cellulose Versus Fiberglass Insulation
Insulation in the attic plays a major role in slowing down the movement of heat from the outside environment into the living space and vice versa. Not only does type of insulation potentially save the homeowner some money on their heating and cooling bills, it can also make the home's inhabitants more comfortable and can reduce the amount of work the HVAC units have to do. However, there are several different types of materials that can be used for insulation. Cellulose insulation and fiberglass insulation are two of the most popular types. Depending on the home's needs, one type of insulation may be better suited than another. A San Antonio roofing contractor can assist in determining the right type of insulation for a particular building.
Both fiberglass and cellulose have a number of similar qualities. For example, both types of insulation have similar R values, essentially meaning that they provide the same amount of heat transfer resistance. Additionally, neither types of insulation act as a complete air barrier. This means that the materials themselves will allow air to pass through if they are not paired with air barriers. Both cellulose and fiberglass insulation are particularly weak against moisture infiltration, especially if they are paired with a vapor barrier.
In terms of cost, both fiberglass and cellulose are relatively inexpensive when compared with other types of insulation.

Additionally, both types are relatively easy to install with the help of professionals. If homeowners attempt to install the insulation themselves, the material's effectiveness may be reduced.
Even though both types are similar in many ways, there are some common differences between the two. For example, fiberglass is made from spun glass and does not burn at normal temperatures. In fact, it is more likely to melt than ignite should a home catch fire. Cellulose, on the other hand, can easily catch fire. Modern cellulose is usually treated with boric acid, which acts as a flame retardant.
The other major difference lies in the material itself. Fiberglass can be made of recycled materials, but usually raw materials are used because the glass has to be spun into threads. Most cellulose products are made out of recycled paper. There are typically less energy requirements in the manufacture of these paper materials.
The type of insulation that is used for a particular project depends on the project itself and what the homeowner wants. For example, cellulose may be a better option if the attic space is cramped or if the homeowner wishes to use a recycled product.
