Sink base cabinets are among the most susceptible to damage from repeated exposure to moisture, plumbing leaks, and humidity within a kitchen. Therefore, the materials used to build these cabinets beneath the sink must provide sufficient protection against water damage while remaining structurally sound throughout their lifespan. Marine plywood has become one of the accepted materials to accomplish this because of its unique design requirements to function properly in environments that are consistently exposed to moisture.
Water Resistant Properties
One type of property that must be present within any material used for a sink base cabinet is excellent water resistance. Marine plywood is made from impregnated (waterproof) adhesives that bond the layers of veneer under considerable pressure, which prohibits or significantly reduces the ability of water to penetrate the inside layers of the manufactured board.
There are frequent spills of water under the sink or leaks from pipes; there will be condensation and/or other forms of moisture present in an under-sink area. In these circumstances, most plywood will absorb moisture and swell, warp, or break down over time. By contrast, marine plywood is engineered to withstand long-term exposure to moisture without losing its structural integrity.
Strong and Stable Construction
Marine plywood is constructed from several layers (usually eight) of high-quality veneers that have been cross-laminated. Cross-laminating means that each layer of veneer has been placed side-to-side with the grain running in different directions (90° from one layer to the next). This method of construction creates a tightly bonded, stability-enhanced panel.
Marine plywood’s stable internal structure allows it to support large loads, such as the weight of stone countertops, plumbing hardware systems, and cleaning supplies stored within the cabinet. Additionally, marine plywood continues to retain its dimensional and structural integrity even if it is subject to constant use.
Warpage and Delamination Resistant
Low-quality plywood frequently warps or delaminates due to the effects of humidity and temperature changes. This occurs when moisture penetrates the plywood’s core and weakens the adhesive holding the layers together.
Because of its waterproof construction and cross-laminated layers, marine plywood will not sustain either of these weaknesses, as the waterproof bonding will prevent moisture from impacting the internal layers of the plywood substrate. Thus, the cabinet base will remain stable over long periods regardless of the damp kitchen conditions they experience.
Durability Over Longer Periods of Time
In addition, marine plywood can be relied upon to provide long-term performance. Its resistant properties (water, fungus, and fungi) will allow for the performance of the cabinet to last for many years after installation. The highest quality marine plywood manufactured using technically advanced bonding technology, such as that manufactured by Royale Touche, provides exceptional structural integrity and performance durability for interior uses.
Conclusion
Marine plywood represents an ideal option for use in the fabrication of sink base cabinets, as its superior water-resistant performance, excellent structural integrity, and long-term durability make it the premier choice for kitchen cabinets in applications where the environment imposes difficulty.
