In construction, 18mm plywood is often used as a subfloor or roof sheathing material. Its strength and durability make it ideal for supporting the weight of floors and roofs, as well as for withstanding the elements.
Plywood is also used as a sheathing material for exterior walls, where it provides a stable base for insulation and cladding. It can be cut and shaped to fit around windows and doors and can be finished with a variety of coatings to protect it from moisture and weathering.
Another common use for 18mm plywood in construction is as a formwork material for concrete. Plywood formwork can be easily cut and formed to create custom shapes and sizes, and can be reused many times, with fast construction speed, especially suitable for pouring concrete structures or components with complex shape changes;
Secondly, due to the low thermal conductivity of wood, the wooden formwork has a certain effect on heat preservation and maintenance during concrete winter construction.
The use of 18mm plywood constituted a large proportion of the overall project cost. Correct selection of building formwork can save costs and shorten the construction period.
The main types and characteristics of architectural wood formwork.
There are three main types and constructions of architectural wood formwork: architectural red-faced formwork, phenolic mirror-finished formwork, and laminated formwork.
Construction red board is the earliest product of construction formwork. It can still be seen anywhere on the construction site. The red face template of the building has become a small red board and a red board. The surface is red melamine waterproof glue. The board core is made of different wood materials such as poplar, pine, and eucalyptus. Its weight is low and easy to use. It is usually suitable for some basements, workshops, and ground floor construction.
The phenolic mirror clear water formwork is an upgraded product. Construction red board. Its main feature is that the surface adopts more advanced phenolic glue, which has better waterproof performance, smoother surface, and more convenient de-molding because its surface is as smooth as a mirror.
The mirror clear water laminated board can be used the same number of times as the architectural red formwork. But the clear water mirror template red template is more convenient to use. Therefore, the practicability of phenolic mirror panels is more prominent, thus replacing architectural red panels.
Laminated formwork is the best of the three products. The surface is coated with black or red coated paper, made of special glue, which makes the surface of the laminate template smoother and smoother.
Compared with architectural red formwork and phenolic mirror panels of the same thickness, laminated panels can be used more times. The manufacturing process is complex and there are more materials. The price is higher than the above two templates, most of which are widely used in the construction of high-rise buildings and bridge projects.
