Fibreboards in construction — properties and uses Which statement best summarizes common properties and uses of fibreboard products in building work?

Introduction / Context:
Fibreboards (e.g., hardboard, medium-density fibreboard, insulating fibreboard) are engineered wood products. They are widely used for interior linings, partitions, and acoustic/thermal applications due to their processability and uniform properties.

Given Data / Assumptions:

• Products include MDF, hardboard, and low-density insulating boards.
• Manufacture involves wood fibres, resins, and sometimes waxes or fire retardants.
• Typical uses are non-structural interior applications unless specifically rated.

Concept / Approach:
Fibreboards derive their performance from the fibre network and resin bonding. Low-density boards offer insulation and sound absorption, while medium/high-density boards provide smooth surfaces for furniture and interior finishes.

Step-by-Step Solution:

Verification / Alternative check:
Standards and manufacturers’ datasheets specify density, modulus, and recommended applications aligning with thermal/acoustic control and lightweight partitions.

Why Other Options Are Wrong:

• Since A–C are correct descriptors, “All of the above” (D) is the best single choice.
• “None of the above” (E) contradicts well-established practice.

Common Pitfalls:
Using fibreboard in wet areas without moisture-resistant grades; not accounting for fire performance and code compliance; assuming structural capacity without certification.
