Pemko 332CR Neoprene Weatherstripping and Sound Seal - 3'0" x 7'0" Set
The Pemko 332CR is an architectural-grade rigid jamb weatherstrip specifically engineered for high-performance sound control and life-safety compliance. It features a heavy-duty Aluminum Finish housing equipped with a durable Sponge EPDM (ER1BL) insert. This 3'0" x 7'0" set is designed to provide a tight seal against the perimeter of standard door openings, effectively blocking sound transmission, air infiltration, and lethal smoke in commercial and industrial environments.
High-Performance & Life Safety Features
- Acoustic Excellence: Sound-tested under ASTM E90, this gasket is an essential component for soundproofing offices, recording studios, and mechanical rooms.
- Durable Sponge EPDM (ER1BL) Insert: The high-quality EPDM seal remains flexible and resilient over time, providing a superior barrier compared to standard neoprene in varying environmental conditions.
- Positive Pressure Fire Rated: Fully compliant with UL 10C and UL 1784 standards, making it suitable for use on fire-rated door assemblies (including those rated up to 3 hours).
- Comprehensive Air Sealing: Rigorously Air Infiltration Tested, this seal significantly reduces drafts and unconditioned air loss, improving overall building energy efficiency.
- Eco-Friendly Certification: GREENGUARD Gold Certified for low chemical emissions, ensuring it meets strict standards for indoor air quality in schools and healthcare facilities.

Pro-Tip for Soundproofing Projects
The Pemko 332CR is a "gold standard" for remediating sound leaks around the door jamb. Because the rigid aluminum housing allows for precise adjustment against the door face, you can achieve a much tighter seal than with adhesive-backed gaskets alone. For maximum decibel reduction, pair this perimeter seal with an automatic door bottom to seal the critical gap at the floor.
