Lauan As Underlayment | A Business Article
,[link widoczny dla zalogowanych]
Lauan plywood is derived from specific wood species grown in the tropics specifically within the southern Pacific Rim and Asia. These varieties of woods are lighter and softer thus they are great for intricate details of homebuilding. As compared with other plywood types, lauan is not recommended for construction purposes. The wood is much more delicate and is vulnerable to degradation. Expert homebuilders recommend this plywood type for underlayment uses. Its smooth surface and availability make it suited for floor remodeling. It can also go well with specific types of floor finish such as carpet, hardwood,[link widoczny dla zalogowanych], or vinyl tiles.
The delicate yet tough quality of lauan makes it the best material for realizing detailed home designs. As such, this plywood has been widely used for different woodworks and miniature projects. It is considerably inexpensive and it is very workable. You can easily shape the plywood into your preferred design without peeling or scratching the outer surface. However, homebuilders use lauan sparingly because of its poor stability. This is most commonly used for detailing and not for structural reinforcement. Other uses of lauan include miniature crafts making, kayak or boat projects, and furniture detailing.
Manufacturers classify lauan into two categories: the Type 1 that uses exterior glue and Type 2 that uses water-resistant glue. Between these two types, Type 1 is best for underlayment purposes because they can easily be stamped to fit every corner of the flooring. There is another grading system that measures the face-quality of the lauan: BB, OVL, and CC. It is highly recommended to use only the BB lauan grade because of its high quality. Take note that these two categories only differentiate the characteristics of the plywood and not its reliability as construction material. The construction industry does not have a dependable gauge of the performance of lauan as underlayment.
While some homebuilders use this type of plywood as floor underlayment,[link widoczny dla zalogowanych], there are others who prefer hardwood to lauan. The layers of the lauan provide a medium for moisture absorption and sometimes the surface delaminates when soaked with water. This causes the floor finish to disintegrate. Worst, this plywood can expand noticeably and leave the ceramic tiles in poor shape. Some home remodelers prefer to change lauan underlayment because of these reasons while others recommend additional support such as installing backerboard on top of it, and overlaying gypsum layers and cement-based adhesives. It is cost-effective if you just mount a layer of glueless vinyl on top of the lauan. What's great about this material is that it contains a fiberglass backing that provides weight therefore it fastens itself into the lauan without the need of glue or adhesives. Just be sure that all edges are properly fit to avoid accidental scraping or dislodgement. However, if you are planning to scrape-off the lauan underlayment, you can install newer materials such as synthetic floor fillers,[link widoczny dla zalogowanych], ceramic backerboard, or hardwood. Remember that removing the lauan underlayment is rather costly and time-consuming.
There are lots of suppliers of lauan plywood and you can check online for reputable manufacturers. But before you purchase lauan, make sure that you consult a professional homebuilder to help you decide whether lauan is great for your project.
