Plywood
Plywood by Virgolam is made of premium quality natural wood with the best wood refining and bonding process. The result is an exclusive range of plywood categories, which are used in various different applications. Virgolam, one of the leading Plywood Manufacturers in India brings to its customers an elite product range including General plywood, Block Board, Shuttering plywood, Marine plywood, Flexi plywood and Chequered plywood. Made up of thin layers of wood bonded together with a strong adhesive, each type of plywood has distinct application offering strength and style to any surface.
General Purpose Plywood
Veneers from high quality logs are mechanically dried and they undergo stress relieving process, which are assembled in such a way to form a balanced construction. High quality fortified synthetic resins are used for gluing the veneers. Glue line is poisoned by special formulations of chemicals to make Virgo Plywood safe against borers. It is hot pressed under proper temperature and more than 16 Kg/cm2 specific pressure. Conditioning is done after pressing, followed by preservative treatment.
Applications
Cabinets, Almirahs and other furniture, Door Partitions, Shelves and other interior applications; Roofing, Fencing, and other external applications.

Block Board
These are made out of excellent quality of Plantation Timbers. Logs are quarter sawn into Planks using SDR method, which are chemically treated and well seasoned before converting into battens in a multiple ripsaw. Battens are sandwiched between two glued mechanically dried veneers and are pressed in hot press under accurate temperature and pressure. Quarter sawing of logs and proper seasoning of planks make it dimensionally stable and treatment of planks, poisoning of glue line and preservative treatment of finished block board make Virgo durable and safe against borers.
Applications
Cabinets, Almirahs and other furniture, Door Partitions, Shelves and other interior applications; Roofing, Fencing, and other external applications.

Shuttering
Virgo offers a high quality Shuttering IS : 4990, Shuttering Plywood. It is a multi functional product, which can be used in construction industry for buildings, bridges, heavy industry and structures etc. for use on walls, slabs, columns and beams etc. In Virgo Shuttering Plywood, compression is about 60% more as compared to ordinary Film Face Shuttering plywood available in market. Extra compression leads to better nailing and screw holding properties. Its load bearing capacity is also enhanced due to extra compression. It is manufactured by selecting quality veneers impregnated with modified RPF resin for longer life and better performance in all applications. Impregnation of resin in veneers is more than 30% to the weight of veneers. Virgo offers a high quality Shuttering Plywood and Concrete Shuttering Plywood. It is a multi functional product, which can be used in buildings, bridges, heavy industry and structures construction etc. Extra impression leads to better ridges and long life holding properties. Its load bearing capacity is also enhanced due to extra compression.
Applications
Partition and paneling, ceilings in public rooms and corridors, floor underlayment, computer rooms, furniture, bus bodies, railway coaches, milk booths, sign boards, insert in panel doors, storage racks.

Flexi
Furniture designing is now an artistic pursuit. Flexi Ply is a boon for designers. Keeping in mind the artisan’s vision of unconventional style, we present the Flexible Virgo ply which can be easily bent into any shape without chipping, cracking, peeling or staining; resulting in a wide range of creations which otherwise would have been impossible. Virgo Flexi Ply is gifted with many specialties. Firstly, no special equipment is required to bend, fabricate or laminate. This makes the work of the carpenter easy as he does not need to gather extra knowledge for using it. Virgo Flexi Ply is available specially in 8×4 ft. size which can be easily bent by hand. A bend radius of as little as 25mm makes this product ideal for tight radius work. Shapes can be formed without intensive effort.
