VVSD ducts are becoming more and more common in commercial applications; however, traditionally, the market has not had a great solution for lining ducts with such a small diameter. The outcome has been that shops must dedicate weeks of time to custom fit duct liner to VVSD duct applications. This is a labor killer and extraordinarily costly to fabrication shops. VVSD Spiracoustic Plus changes this entire process. It is designed to streamline the insulation installation process for ducts of all sizes - this saves time, money, and skilled labor for the shop, while ensuring that VVSD ducts have both a thermal and acoustical insulation solution.

Spiracoustic Plus Spiral Duct Liner, VVSD (very, very small diameter) is 1” thick, and the first, prekerfed, single-wall spiral duct insulation engineered specifically for spiral ducts with an outer diameter of 6 to 8 inches. It is designed to streamline the insulation installation process for ducts of all sizes - this saves time, money, and skilled labor for the shop, while ensuring that VVSD ducts have both a thermal and acoustical insulation solution.
