Discussing the prices, pros and cons to determine if fiberglass siding is right for your home

Keeping your home protected from the elements while also providing an attractive covering can be done using a variety of materials ranging from vinyl siding to brick veneer. A newer coverage material currently on the market that is quickly gaining popularity is fiberglass siding. Prices for fiberglass siding are slightly higher than those for vinyl siding, but the advantages of using the material may make the higher price worthwhile if you're looking for a combination of durability and good looks. Before installation, you should look at fiberglass siding pros and cons to determine if it's right for you.

Fiberglass Siding

Fiberglass siding Fiberglass siding has many of the same advantages as vinyl siding. The material is crafted with graining on the surface to make it appear much like wood siding. Many vinyl siding materials are also molded to appear as wood siding to preserve a more traditional look. However, the process of manufacturing fiberglass siding differs greatly from manufacturing vinyl. While vinyl siding is pressed through a die to shape the material, the glass fibers in fiberglass siding are first pulled through plastic to create the base material and then put through a die to provide shape and texture. This process ensures that there is a continuous strand of fibers running through the plastic to provide strength and flexibility.

The glass fibers in fiberglass siding will not expand due to heat, and they prevent the plastic that the fibers are bound to from expanding as well. This keeps the siding from expanding during hot days, a condition occurring with other siding types that can often lead to brittleness, breakage or cracks. The lack of expansion also allows fiberglass siding boards to be butted tightly together upon installation, reducing the seams between boards for a more attractive look. The glass fibers also give the siding great strength, allowing it to lay straight without any sagging, and give it durability to stand up against any impact that may crack other siding products.


There are a few cons to consider if you want to install fiberglass siding. The primary disadvantage is the high cost. Generally, fiberglass siding costs run about 15 to 20 percent more than the costs of vinyl siding for the material alone. The cost of materials does not include the higher labor cost that may be required due to the need for specialty installers who have experience with this newer product. You can find a siding contractor online using the listings available at QualitySmith.

A second con is the limited availability of fiberglass siding. The relatively small number of manufacturers that make fiberglass siding may make it a difficult product to find. Because it's a newer product, color options are limited as well, though the siding can be painted after some preparation for plastic-based products.

For those looking to install fiberglass siding, prices may be a significant issue. The total cost should be available through siding estimates provided by contractors prior to installation. However, the durability and look of fiberglass may help you overcome any price reluctance, allowing you to protect your home while also achieving an attractive, traditional look.
