BIS Certification is a mandatory requirement for Wooden flush door shutters (cellular and hollow core type) with plywood face panels, as specified by BIS IS 2191 (Part 1): 2022. Widely utilized in both residential and commercial construction, these door shutters offer a balanced combination of price, strength, and style, primarily characterized by their hollow or cellular (honeycomb) core construction with plywood face panels.

Two common types of these door shutters are:

Cellular Core Wooden Flush Door Shutters: with a honeycomb-like structure made of lightweight materials, such as corrugated cardboard, cellular core doors are reasonably priced and lightweight. They are suitable for interior applications, offering decent soundproofing and insulation qualities.

Hollow Core Wooden Flush Door Shutters: a hollow or empty area inside the door frame, typically covered with plywood face panels, hollow core doors are affordable and lightweight. While suitable for indoor use, they may not provide as much soundproofing as solid core doors.

Manufacturers in the woodworking and construction sectors must adhere to the IS Standard IS 2191 (Part 1):2022 for hardwood flush door shutters to ensure the production of high-quality door shutters that meet strict standards. This standard outlines precise specifications for components, workmanship, and functionality, ensuring the creation of durable and top-quality door shutters.
