LE SUEUR, Minn., May 5, 2011 (GLOBE NEWSWIRE) -- Cambria, the only American company in the quartz surfaces business, announced today it is launching 12 new colors this spring, bringing the company ...
Cambria even offers a lifetime warranty on its products. Quartz doesn't need to be sealed with chemical substrates several times a year the way porous materials like marble and granite do.
Cambria quartz surfaces are 93% pure quartz. Granite typically only contains 40–60% quartz, along with more porous, weaker minerals. And as a result, granite tends to be more susceptible to damage.
Cambria produces around 30,000 slabs of quartz countertop material every month, says Davis, who adds that the company has also spent millions of dollars on air-handling systems to control dust.
Cambria's 800-pound quartz countertops are snatching market share from companies that make granite, marble and manufactured stone countertops. Five years ago, Cambria had nearly 60 stone designs.
The thing about granite and quartz (compared to the likes of, say, marble and wood) is that they both live up well to these requirements, making the dilemma of which to choose all the more difficult.
