Granite vs Quartz Countertops

It is generally understood that granite and quartz countertops are the same in characteristics as well as performance. While this is not absolutely the case, the two types of countertop materials are very similar. At a recent NKBA chapter meeting, we learned a little more about the technology used in creating manufacturing quartz and how they compare with granite and other solid surface materials.


Some Highlights:


There are considerably more grades of granite than there are of quartz materials. Granite allows for more variation for those who are looking for this type of aesthetic look. Due to its precise manufacturing process, quartz has less variation and a more consistent look thoughout the slab.


Quartz is manufactured with quartz silica made up primarily of quartz crystal material and resin. The way in which a quartz slab is made, called the Breton process, creates a finished slab that is densely packed with none of the fissures that may be present in granite. This feature of quartz surfaces provide for increased hardness over granite countertops and a greater flex strength.


Quartz surfaces are also presented as being a lower maintenance product than granite and other stone surfaces. Manufactured quartz surfaces are non porous and, according to numerous resources, do not require sealing.


It is important to state that the manufacturers and distributors of quartz countertops suggest that slabs and fabricated countertops be handled in a similar fashion as granite is customarily handled. Proper equipment is necessary for installation and fabrication. Quartz can be damaged by extended exposure to high heat and will fade slightly over time in direct sunlight. Also, some chemicals can cause damage on quartz manufactured surfaces.


Quartz counters that will have overhang portions or will bear heavy weight should be properly supported with an adequate countertop bracket. As a heavy stone material, the quartz countertop weight is similar to granite and should be supported by functional support brackets attached to a substantial support structure.


Ultimately, the selection between granite and quartz for a kitchen design will be based on customer preference. While there may be advantages using one material over the other, the way the countertop looks in the kitchen is going to matter most.
