VFI-716 is a low viscosity, 0.5 lb density open cell insulating material. VFI-716 is designed to provide significant control of air infiltration along with a high R-Value per inch. When properly installed by a trained contractor VFI-716 quickly expands to fill the cracks, crevices, gaps and voids that exist in every structure.
The proportioning pump ratio is 1 to 1 by volume. The pre-heater initial setting should be 125°F. The initial hose temperature should be 125°F. Equipment must be capable of maintaining temperature settings.
