Expert opinion plywood
Building codes require that certain structures shall be made with fire-retardant or flame resistant plywood. The use of this material in walls and partitions prevents the spread of fire from one part of building to the next. Fire-retardant plywood successfully completes vertical through-roof firewalls, simplifying roofs construction and reducing building and reroofing costs.
Fire-Retardant (FR) plywood stands out from standard Exterior (WBP) and Interior (MR) plywood.
The difference becomes evident during the production process, when peeled veneer for FR plywood undergoes special treatment with fire retardants. Thus, the final product acquires its fire-resistant properties.
To obtain its fire-resistant properties, fire-retardant plywood is treated with special flame retardant during the production process.
FR grade plywood is widely used to reduce the risk of fire in public places such as theatres, cinemas, offices, kitchens of restaurants as well as for cladding in residential buildings. Another major application of fireproof plywood is rolling stock construction. Fire rated plywood is also used for furniture production. The structures made of fire-retardant plywood are more expensive but the choice is always evident for those for whom safety is a major concern.
Birch plywood is one of the materials used for the production of parquet and engineering boards. It is one of the most demanding areas of plywood application. Although all the companies have their individual requirements, there are some issues that are equally considered to be very important by all of them. Birch plywood for parquet shall have optimal moisture content and high load bearing capacity.
Exterior birch plywood overlaid with colored phenolic films is light-weight material with highly wear-resistant surface, which is unaffected by detergents and many other common chemical substances. It can be easily processed and combined with other materials. Colored film faced plywood can be used in demanding outdoor conditions as it withstands humidity and temperature drops. Unlike standard laminated plywood, it is UV resistant and can be exposed to sunlight for a continuous period of time.
