Is Plywood Required for Granite Countertops?
When it comes to installing granite countertops, there is some debate as to whether or not plywood is required as an underlayment. The thickness of the granite determines the answer. A plywood underlayment is not required for granite with a thickness of 3 centimeters (about 1 1/4 inch).
However, for granite with a thickness of 2 centimeters (about 3/4 inch), plywood will be required for support. The plywood adds additional support and helps to keep the granite from cracking. So, when installing granite countertops, keep the thickness of the stone in mind. This will determine whether or not plywood is required as an underlayment.
Why Plywood is Used
Plywood is often used as an underlayment for granite countertops because it provides extra support and helps to prevent cracks. For thinner pieces of granite, the additional support offered by plywood can be crucial in preventing cracks. In addition, plywood can help to dampen noise, making it ideal for use in kitchens where there is a lot of activity.
When Should Plywood Be Used?
Plywood should be used when installing granite countertops that are 2 centimeters thick or less. For thicker pieces of granite, a plywood underlayment is not necessary.
Installing granite countertops can add beauty and value to your home. When deciding whether or not to use plywood as an underlayment, keep the thickness of the granite in mind. Plywood will be required for thinner pieces of granite but is not necessary for thicker pieces. Using plywood can offer additional support and help to prevent cracks.
