Full Name

ICC-ES AC271 – Acceptance Criteria for Alternative Gypsum Board Supports (AGBSs)

Scope

ICC-ES AC271 – Acceptance Criteria for Alternative Gypsum Board Supports (AGBSs) covers the evaluation of non-traditional methods for supporting gypsum board in building construction. These alternative supports aim to replace or supplement conventional wood or metal framing.

The scope of AC271 includes:

  • Material properties: evaluation of the materials used in AGBSs, including their strength, durability, and compatibility with gypsum board.
  • Design and installation: assessment of the design and installation methods for AGBSs, ensuring they provide adequate support for gypsum board and meet building code requirements.
  • Structural performance: evaluation of the structural performance of AGBSs, including their ability to resist loads and maintain stability under various conditions.
  • Fire resistance: assessment of the fire resistance of AGBSs, ensuring they meet the necessary fire safety requirements for building construction.

By establishing these acceptance criteria, ICC-ES AC271 aims to ensure the safe and effective use of AGBSs in building construction. It provides a standardized framework for manufacturers, designers, and building officials to assess the suitability of AGBSs as alternatives to traditional framing methods.
