How to Build a Sound Proof Room - Building Methods and Insulation

INTERIOR WALL SOUND CONTROL INSULATION


Product Description:

Sound Control Batts like Johns Manville’s ComfortTherm ™ are polywrapped encapsulated fiber glass designed for reducing sound transmission through interior walls or floors. Because sound control performance depends on insulation thickness, not density, the ComfortTherm Sound Control Batts are 3 1/2" thick, made to fill standard 2' x 4' wood frame cavities.


Applications:

ComfortTherm Sound Control Batts significantly reduce unwanted sound transmission from appliances, TVs, stereos and ventilation systems when installed in standard interior wood frame cavities. Since ComfortTherm Sound Control Batts are designed for use inside interior walls and floors, they are perforated and do not perform as a vapor retarder.

Features And Benefits:
• Comfortable installation. The unique poly-wrap greatly reduces itch and dust from airborne fibers.
• Convenient installation. Batts are pre-cut to fit standard wall sizes. Stapling flanges allow attachment to wood framing. Batts can be cut with a standard utility knife to fit any cavity size. Available in pre-cut 15" wide, 3 1/2" thick batts.
• Fire-resistant. ComfortTherm is UL classified 25/50 and Class A fire-rated for flame spread characteristics.
• Tougher. The poly-facing and triple-reinforced stapling flanges are more tear resistant than kraft paper.
• Low environmental impact. ComfortTherm's content is independently certified by Scientific Certification Systems to contain at least 25% recycled glass.
• Breathable. Poly-Wrapped encapsulation facings on this product are perforated on all sides to allow moisture to escape.
