At one time, masonry and wood were virtually the only materials available for domes. Today, anyone intending to purchase a dome will likely be able to choose from a number of modern, lightweight materials. GFRP domes and fiberglass reinforced concrete domes in particular are quite popular. Both dome materials have unique features and benefits, so choosing between them can be challenging. This article will provide more information on fiberglass reinforced concrete domes and GFRP domes to help people make an informed decision on which type is best for a given project.
Fiberglass reinforced concrete domes
Overview: GFRC domes are made from a blend of genuine Portland cement and fiberglass for strength. Fiberglass reinforced concrete domes look like concrete, but are much lighter. GFRC domes are cast in molds to achieve precise results.
Advantages: In addition to being lightweight, GFRC domes are also extremely strong. Fiberglass reinforced concrete domes are resistant to rust and rot, and can withstand exposure to salt spray and high levels of humidity.
Design Possibilities: GFRC domes can be placed indoors or outdoors. This material is the best choice for those looking for a paintable item, as many manufacturers offer GFRC domes in a painted finish. Many producers of fiberglass reinforced concrete domes offer integral colors and textures, and they can also be molded to contain ribs or coffers, or to look like shingles.
Best For: GFRC domes are best for those who want the look of concrete without the high weight and associated problems.
Fiberglass Architectural Domes
General Description: GFRP domes are made from a mixture of polyester or epoxy resin and glass fibers. Like GFRC domes, GFRP domes are cast using moulds, so a wide variety of shapes and textures are possible.
Advantages: Fiberglass architectural domes offer a number of advantages over those made of other materials. GFRP domes are often more affordable than those made from precious metals and stones, and are also exceptionally durable and strong.
Design Possibilities: GFRP domes offer an almost unlimited number of design possibilities. Fiberglass architectural domes can be manufactured to match any color swatch, and can also replicate a variety of spectacular and very expensive materials, including bronze, gold, copper, granite, limestone, and marble.
Best For: Fiberglass architectural domes are the best choice for people who want an affordable, durable material that offers a host of design options.
