Let’s Explore the Different Types of Plywood Used for Roofing
Below are the different types of plywood used for roofing:
CDX Plywood
CDX plywood is what you’ll see most commonly used amongst roofing companies across America. There are multiple layers of wood within the pieces of plywood themselves, which are then bonded through a waterproof adhesive matter. The “CD” in “CDX” indicates one side of the plywood is a “C-grade” which includes wood with knots and imperfections. The other side of the plywood is a “D-grade” which includes wood with further defects. The “X” in CDX plywood indicates it’s suitable for exterior use. CDX plywood is affordable and suitable for many roofing projects, making it a popular choice amongst roofing companies nationwide.
ZIP Wood
ZIP Wood is a form of engineered plywood which offers many unique benefits when compared to other forms of plywood. ZIP Wood features integrated waterproofing solutions and barriers. This eliminates the need for additional underpayments, making the process much more efficient for roofers. ZIP Wood is a fantastic choice of plywood for those who live in humid environments and for those who want a plywood which is quite resistant to moisture, mildew, and mold accumulation.
FRT Plywood
FRT plywood, also known as “Fire-Retardant Plywood” is a great option for non-metal roofing materials, as those materials are more prone to flammability should some type of flame strike the non-metal roofing material. FRT plywood is treated with a fire-retardant chemical which slows combustion and subsequently reduces the spreading of flames. This type of plywood is certainly more expensive than standard forms of plywood, yet you’re paying for an added layer of protection and safety should any flaming debris or materials land on your rooftop.
