CDX is a type of plywood made up of thin veneer sheets glued and bonded together by bonding layers. “C” in CDX means one side of the plywood is Grade C and the other is Grade D. “X” stands for exposure, which is the type of glue used to bond the plywood.
There are different grades/classes of plywood represented by the letters A, B, C, and D. The fewer knots, voids, and repaired defects, the closer the plywood will be to Grade A, and consequently, the more expensive it will be.
CDX, with its C/D rating, indicates a higher number of knots and defects, making it a cheaper plywood with little aesthetic value. However, the rating is not about quality but rather the appearance of the wood.
However, the tasks that CDX is intended for require more quality than good looks, making it a low-cost and easy-to-handle option.
CDX Characteristics:
CDX plywood is known for its resistance to water, cracks, breaks. CDX is not about aesthetic value but contributes to other aspects such as strength, flexibility, easy handling, and damage resistance.
Uses of CDX Plywood:
CDX is a great cost-effective option for base applications, constructions, and temporary protections against weather changes, such as hurricanes, due to its effectiveness and low cost.
Because of its characteristics, strength, and resistance, the material is also suitable for external applications. However, CDX plywood is mainly used in construction as a base for walls, ceilings, and floors, and can also be used in small industrial buildings and for roof coverings.
One of the most crucial applications of CDX in hurricane protection is its use to reinforce the house’s structure and protect its openings. CDX can be installed at strategic points, such as roofs, walls, and doors, to increase the house’s resistance to strong winds and heavy rain associated with hurricanes.
Additionally, it can be cut and applied over windows and doors to create a physical barrier against debris and high-speed winds. Ensuring safe and proper installation is essential to maximize the effectiveness of CDX as a protective measure.
