Advantages and Disadvantages of Fiberglass Insulation
Fiberglass insulation is one of the most popular types of home insulation, accounting for about two-thirds of the market for new single-family homes. It has a few advantages over other materials, though. First, it is relatively cheap. Second, it traps air pockets, making it both warm and cool. Third, it has good thermal performance, making it one of the best materials to hang in your home. But there are a few disadvantages to fiberglass.
Producing fiberglass insulation involves melting molten glass in a giant oven. The molten glass then spins out of the container, which causes the filaments to separate. The glass is then sprayed with oil and binders and pressed into a mat to be used for batt insulation. The resulting product is called fiberglass insulation. It has a high R-Value, representing its resistance to heat flow. The higher the R-Value, the greater the potential savings in energy costs.
Another advantage of fiberglass insulation is that it limits air movement in a space. As a result, warm air moves toward cooler spaces. However, fiberglass insulation blocks these movements by trapping air between the fibrous strands. This creates a barrier between a room and outside air, eliminating convection and conduction. This means that the resulting air is cooler, which effectively insulates the space. When winter temperatures are high, heat is naturally displaced from a space into a colder one. Colder air has to be kept inside the home during the summer months, and this makes it necessary to have a solid barrier between the prevailing temperature outside and the living space inside.
The most common form of fiberglass insulation is called batts. These large, rolled-up sheets of fiberglass insulation are held together by reflective aluminum foil and paper acting as an adhesive vapor barrier. This type of insulation is the most straightforward to install, although it can be a hassle if your attic has obstructions such as boxes. Batts are best suited for new constructions and gut renovations. They also maintain their R-value even in cold weather.
The Centers for Disease Control and Prevention categorize fiberglass as hazardous. Its effects on human health are unknown, but research has shown that fiberglass can cause physical irritation and even breathing difficulties. Manufacturers are researching alternative options to avoid these risks. If you have a home that uses fiberglass, make sure to read the HIRL. The HIRL will show what grade the fiberglass installation is. If it doesn’t, it isn’t safe.
Another problem with fiberglass is that it releases fibers when disturbed. Fiberglass particles are small enough to breathe in, but when you touch your face or nose, those fibers may irritate your respiratory system. In addition, fiberglass can irritate your nose and throat. So be careful where you place fiberglass insulation. A good rule of thumb is to limit the number of pieces of insulation you install in your home. If you can’t afford to replace your existing insulation, choose insulation with a higher R-value.
In general, fiberglass insulation is inexpensive. It costs between $0.88 and $1.64 per square foot and averages out to around $300-600 for a 500-square-foot job. Despite the cost, installing insulation is not difficult, though improper installation is a common issue. If you’re doing the job yourself, the cost can be as low as $25 to $50 per hour. So, you might as well consider hiring a professional to do it for you.
A quality fiberglass insulation installation will help you save money on your energy bills. The average home uses 50 percent more energy than it needs. The primary culprits are air leakage and inadequate insulation. Proper insulation will help keep the temperature inside and the air outside comfortable. If you’ve decided to do it yourself, you’ll save money by avoiding costly contractors and labor costs. However, if you’re inexperienced or don’t have the tools for a particular task, you can also rent the necessary equipment and supplies.
