Use of Plywood in Construction
by Ankita Sehgal Freelance Blogger, Lives in New DelhiOwing 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.
