A revolution in door manufacturing is quietly taking place. Trending are the engineered doors certified under IS 2191 Part 2: 2022, the industry is on the brink of significant transformation. The long-standing belief in the inherent superiority of solid timber-infill doors is being challenged by these innovative alternatives.

The doors adhere to four distinct standards tailored to various materials and applications:

IS 2202 (Part 1) – 2023: Wooden Flush Door Shutters (Solid Core Type with Plywood Face Panels).

IS 2202 (Part 2) – 2022: Wooden Flush Door Shutters (Solid Core Type with Particle Board, High Density Fibre Board, Medium Density Fibre Board, and Fibre Hardboard Face Panels).

IS 2191 (Part 1) – 2022: Wooden Flush Door Shutters (Cellular, Hollow, and Tubular Core Type with Plywood Face Panels).

IS 2191 (Part 2) – 2022: Wooden Flush Door Shutters (Cellular, Hollow, and Tubular Core Type with Particle Board, High Density Fibre Board, Medium Density Fibre Board, and Fibre Hardboard Face Panels).

Despite the variations in their construction, the performance criteria for these doors remain consistent, effectively debunking the myth that solid timber doors are superior. These flush door shutters can be classified into two grades:

- BWP (Boiling Water Proof) Grade, suitable for both humid and dry locations, and

- MR (Moisture Resistance) Grade, recommended for dry locations only.

By February 28, 2025, all flush doors will be required to display the ISI mark, ensuring they meet mandatory quality control standards. The rigorous Type Tests they must undergo include dimensions and squareness tests, general flatness, and local planeness tests and a series of other assessments like impact indentation, flexure, edge loading, shock resistance, buckling resistance, slamming, misuse, varying humidity, end immersion, knife, glue adhesion, and screw withdrawal resistance tests.

The Acceptance Tests further ensure the doors' quality and durability through assessments, such as dimensions and squareness tests, general flatness and local planeness tests, slamming tests, end immersion tests, knife tests, and glue adhesion tests.

The advantages for manufacturing engineered doors are numerous. There is no longer a need to search for quality wood, season timber, or perform chemical treatments. Energy costs during production are minimized, labour costs are reduced, and production efficiency is increased, all while achieving a superior finish.

Moreover, these doors are eco-friendly and sustainable, utilizing high content engineered materials, including sawmill waste and shavings. Additionally, the engineered doors have better acoustic and stability features.

This shift towards engineered doors also aligns seamlessly with the growing trend of modular wooden furniture. As the modular furniture market expands, the need for versatile, high-quality components becomes critical. Engineered doors, with their superior finishes and adaptability, fit perfectly into this landscape, offering both aesthetic appeal and functional reliability.

Engineered doors represent not just a technological advancement but a sustainable and efficient solution for the future of door manufacturing. By embracing modern materials and standards, the industry can look forward to a future of innovation, productivity, and quality assurance.
