Re-Glass compared to stone surfaces
January 14, 2009
When deciding on a usable surface whether it is a counter, table top or other functional surface the user will need to consider aesthetics, durability, maintenance, bacteria resistance and expense. Re-Glass is a 100% glass surface and compares favorably across the board to all natural stones and concrete when looking at all of these factors. Aesthetically Re-Glass like many stone surfaces can have both a smooth and naturally rough surface. The luminous quality of glass is unique by comparison.
The durability of these materials is generally expressed in Hardness, Impact resistance, Stain resistance and Usable life. Top Quality granite is the hardest of the stones rating a 6 to 7 on the Moh’s hardness scale. Most commercial granites are 4 to 6 and all other stones; marble and travertine etc, are 3 to 5 on the scale. Re-Glass is 5.5 on the Moh’s hardness scale the same hardness as a knife blade.
Impact resistance is measured relative to dynamic crack resistance and is dependent upon the structural matrix of the material as well as the impact instrument shape and size. Studies show that non-homogeneous materials such as natural stones have a wide variety of resistance largely dependant upon the amount of structural flaws inherent to them. Black granite has the highest resistance, travertine the least. All glass is a homogeneous material and thus rated much higher in Impact resistance tests. Re-Glass has shown to be slightly less impact resistant than pure heavy float glass yet remains equal to and generally higher in impact resistance than stone surfaces.
Natural and manmade stone surfaces are generally susceptible to staining and discoloration with the amount specifically dependent upon the quality of the stone. Citrus, vinegar and many cleaning products mar stone, often permanently. Re-Glass is completely stain resistant.
The usable lifespan of granite and hard marbles with high quartz content matches that of Re-Glass while lesser quality stone surfaces expect a shorter lifespan. Re-Glass is the only surface that is recyclable and can become another usable surface.
Maintenance of natural stone is extensive with most industry standards requiring at least resealing and waterproofing minimally every 36 months. Re-Glass is completely cleanable and impervious to water, staining and invasion of bacteria. In a recent study of bacterial resistance the results show that glass, stainless steel and granite have the best clean ability in that order, laminate, ceramic tile, concrete and wood follow.
The expense of stone surfaces varies greatly. Generally the higher the quality the higher the price point. Re-Glass compares favorably with most granite being installed in finer homes today.
The weight of Re-Glass and granite are almost identical as are their specific gravity and thermal shock resistance although it is never recommended to place hot pans on either surface.
We hope that this comparison helps you out. You can contact us for the specific studies referenced in this posting.
