The Four Basic Structural Properties of Construction Plywood

Plywood is made from several layers of soft and hard wood which are glued together to create a thick and flat sheet. Plywood is widely used in the construction sector for several purposes, i.e. making a light partition or external walls, wooden beams, holding concrete, etc. Plywood is a reliable product due to its structural properties explained below:
Structural strength and durability
Plywood is made from strong wood such as pine wood and Douglas fir trees. The grains of each layer are laid at 90-degree angles to make them effective and solid. This prevents the plywood from cracking and splitting, even when it’s fastened to other structures using nails. In addition, plywood’s laminated coating makes it more durable. Such strength and durability make plywood a suitable material for flooring and making wooden beams.
Resisting moisture and humidity
Plywood is highly resistant to both moisture and humidity effects due to the strong adhesives used to stick the layers together. A polished layer will strengthen the plywood’s resistance to dampness effects. This is the reason why plywood is also used in marine construction, building sheds, and many other exterior constructions. Concerning interior applications, the plywood’s moisture resistance is a vital factor considered when instaling the wooden flooring. This is due to the cross lamination design which prevents the layers from shrinking or bending whenever the plywood is exposed to humidity.
 
Plywood is resistant to chemicals
Plywood is well-known to be highly resistant to many chemicals and it is for this reason that it’s used in several chemical applications involving the use of alkaline, and other neutral acid salts. This is because when treated with effective preservatives, plywood doesn’t rust or bulge. Plywood tanks and vessels that are exposed to chemicals do slightly swell, but its cross-laminated structure will significantly lessen any structural changes. The lamination feature also helps to prevent leakages in plywood vessels.
 
Fire resistance and insulation ability
To make it fire resistant, plywood is treated with a chemical varnish. What’s more, the applied varnish is more effective when combined with non-flammable materials, i.e. plaster or leathery cement. This makes it ideal for kitchen construction and designing. 
Furthermore, plywood features a strong thermal and sound insulation ability and this makes it seamless material for shielding the floor, ceilings, roofing and the walls. The insulation makes it energy and cost efficient since it reduces both the heating and cooling costs.
From the above explanation, it is evident that plywood can highly be trusted for use in several construction projects. Even during use, ensure that proper maintenance is given to the flooring, ceiling, walls and any other plywood product. This will help you to enjoy the benefits of using plywood materials for a longer time.
