Use of Plywood in Construction

by Ankita Sehgal Freelance Blogger, Lives in New Delhi

Owing to its useful properties such as moisture resistance and high strength etc., plywood has emerged as one of the most important building materials. Despite being versatile and robust, plywood is an affordable and durable material for small businesses. From floorings to the kitchen cabinet and furniture etc., plywood has multiple applications within the construction industry and its use is only expected to increase with the growth of the global market. The most prominent way plywood is used is in structural applications. Besides being used in bins, crates, boxes, outdoor furniture, and internal structures, etc., structural plywood is also used for hoardings and beams, walls and roof bracing.

Plywood is generally available in a variety of grades, the most common and prominent being A-grade comprising plywood such as BWR plywood.  With an ability to withstand continuous boiling without the need for delamination, this type of plywood is mostly used at places where durability is required. There is also marine plywood which is made using special types of glues that are completely weatherproof and boil proof.

B-grade structural plywood compromises durability but is sturdy enough to be used in concrete formwork and exterior door skins. There’s also C-grade plywood which comprises several minor defects that need to be repaired.  Places where durability and appearance don’t hold much importance such as subfloors and garages, C-grade plywood is used. The lowest on the spectrum is D-grade plywood which is un-sanded and comprises many internal defects. It isn’t uncommon for plywood manufacturers to combine and use different grades of plywood to save on costs. BC- grade plywood, for instance, is made with B-grade plywood on one side and C-grade on the other.  There are also exterior and interior plywood based on the places they are applied at:

Exterior Plywood:

As the name goes, exterior plywood is used in outside applications in items where serious durability is required. Water-resistant glue that doesn’t wear off too easily is used in its making. Walls, stables, roof linings, etc. are some of the places where it is mostly used.

Interior Plywood:

Interior plywood is used at places where aesthetics are a priority. This type of plywood is not highly resistant to outdoor elements and tends to get damaged easily when exposed to heat and moisture. Interior cladding, indoor furniture, and ceilings are some of the places where interior plywood is mostly utilized.

For places such as walls, ceilings, highways, pillars, and drains, etc., where intensely durable plywood is required, shuttering plywood is used that can withstand massive loads. Shuttering plywood is basically highly dense hardwood with at least nine layers of tightly packed core veneers put together using high-pressure machines.  At places that are prone to water damage, marine plywood is used which is made up of high-quality hardwood secured with waterproof glue. It is available in a variety of grades such as high-density overlay, B, A-B, medium-density overlay, etc. Whether you are searching for shuttering plywood manufacturers or any other, Archidply is your one-stop destination for all your plywood related requirements.
