Norseal^® V730/V770 Series Acoustical Sealants

Norton^® Tapes Are the Fastest And Cleanest Way To Install Acoustical Gaskets.
The better the sound transmission characteristics of a wall or ceiling, the more you need Norton^® Tape. Airborne noise leaks around the perimeter of even the best acoustical systems. Just a small gap allows for increased sound transmission and has a detrimental effect on overall acoustical performance. Norton^® Tape seals these flanking paths to help maintain the effectiveness of an acoustical system's Sound Transmission Coefficient (STC).

Norton^® Tape makes acoustical gaskets affordable and easy to install. Specify gaskets between the STC-rated system and dissimilar surfaces, and between the system and similar surfaces where perimeter relief is required. Only 15% compression is required to create an airtight seal against sound flanking, and independent test data is available.

PRODUCT OVERVIEW
Norseal^® V730/V770 is a preformed, closed cell, polyvinyl chloride foam tape used as an acoustical sealant. Its low density controls sound transmission and vibration which makes it ideal for acoustical partitions.

It has a pressure sensitive adhesive on the non-liner side which makes application of the sealant easy and accurate. Its cellular composition will not ooze, drip, or run under compression.

ADVANTAGES
Norseal^® V730/V770 Series Acoustical Sealant Tapes is specially formulated to effectively stop perimeter sound leaks in wall systems.
- The product is used in partition wall systems to control sound transmission and vibration.
- It is compatible as a gasket to panel materials.
- Its low density aids in maintaining the desired STC rating of the wall system when compressed a minimum of 15%.
- V730/V770's low thermal conductivity improves the energy efficiency of the structure.
- Its low density easily conforms to irregular surfaces which allows it to function as an effective light and dust seal.

DESCRIPTION
Pressure Sensitive Norseal^® Acoustical Sealant Tape is a low density, polyvinyl chloride (PVC) foam expanded to a non-connected cellular construction. It offers resistance to oxidation, weather and ultraviolet light. It applies easily to contoured and convex surfaces. There is no problem with breakdown or component deterioration from mild acids, alkalis and mildew. Recovery and compressibility prevents leaks from depressed areas (or with expansion and contraction). The V730/V770 Series Norseal^® Acoustical Sealant Tape has an adhesive on one side only.

CONFIGURATION
The product is supplied in roll form with a silicone coated paper liner. The length of each roll depends on the thickness.

TECHNICAL DATA
Average physical properties for Norseal^® V730/V770 are available from the Saint-Gobain Application Engineering Department.

INSTALLATION
Norseal^® vinyl foam acoustical sealant tape is ready for immediate use. No preparation or setting time needed. As with any pressure sensitive adhesive, the surface must be wiped clean prior to the application of the Sealant Tape. Select a thickness that allows for at least 15% compression to preclude flanking. Simply unroll Norseal^® Acoustical Sealant and set in place. Liner is on the non-adhesive side, thus allowing for rapid installation. Do not remove the liner until the sealant is in place. This prevents stretching of the foam. Applies easily over a wide range of surface temperatures that extend from 40°F to 125°F. No cure time required.

AVAILABILITY AND COST
Norseal^® V730/V770 is available from Saint-Gobain Performance Plastics Corporation and through a network of authorized sealant distributors. Contact Saint-Gobain or an authorized distributor for pricing.
