Coillte Panel Products said BBA approval, which is recognised by building control, government departments, architects, local authorities, specifiers, and industry insurers like the NHBC, means the "Extreme Durable MDF", as the material is also known, can be specified with confidence.

The company said the unbiased BBA report complements its own technical and performance data.

The testing, co-ordinated by the BRE, included on-site evaluations and inspections and auditing of the manufacturing process.

"Gaining the BBA assessment has really underpinned the high quality and durability characteristics of Medite Tricoya," said Peter Clifton, product manager for Medite Tricoya.

"It’s a great achievement and gives our customers peace of mind that the product will deliver on expectations."

Medite Triccoya modified MDF is made using acetylation technology, which Coillte Panel Products says naturally alters the wood’s chemical structure so it does not absorb water.
