Fundamentals of Perimeter Acoustical Ceiling Trim
Improved acoustics, sustainability, and ease of installation converge with innovations in PACT design
Sponsored by TAMLYN | By Andrew A. Hunt
Perimeter Acoustical Ceiling Trim (PACT) is a practical and efficient building product that can provide benefits to architects, builders, installers and occupants in one simple solution. Designing and installing wall and ceiling assemblies in multifamily settings that address acoustic challenges requires evaluating each component of the assembly to ensure that all the parts are working in unison to provide a superior final product. Traditional trims often fail to manage noise and meet environmental standards. PACT solves these issues with innovative materials and design, improving sound absorption and reducing noise transfer for a quieter environment.

TAMLYN is a family-owned company with 50 years in the building products industry and has placed a great deal of recent focus on building science, especially moisture management. This direction led to the development of their TamlynWrap® line, Drainable with its 1.5mm bonded filament creating an enhanced WRB, and RainScreen 6.3 (1/4”) and 10.1 (3/8”). TamlynWrap® RainScreen is a multi-layer water management system, intended for use over existing WRB or coated sheathing, of cavity spaces that are non-compressible and act as a furring matrix to promote enhanced drainage and drying, paired with improved installation efficiency.
