NovaFlex Void and Cavity Filler

A rubber-like solid that will not crack or fall out of joints, NovaFlex Void and Cavity Filler is the best way to reinforce your frame.

NovaFlex Void and Cavity Filler is a non-sagging, non-corrosive, single-component silicone paste that cures upon exposure to atmospheric moisture and remains flexible forever. It is ideal for use as a reinforcing sealant during the window manufacturing process, or to fill voids, gaps, and cavities inside the assembled window frame. It may also be used as a vertical joint sealant and crack filler.

How to Buy
  • Details

    With NovaFlex Beaded Glazing/Bedding Compound, the beads assure controlled compound thickness between the glass and the sash, maximizing sash performance while minimizing sealant consumption.
    Spacer-beads support the glass and maintain uniform glazing depth during cure for tighter manufacturing tolerances, higher quality, and fewer warranty claims. It also eliminates squeeze out, which provides for easier re-glazing.

    We have standard bead sizes for SBC 30, SBC 40, and SBC 50.

    You can tailor your Beaded Glazing/Bedding Compound with a specific spacer-bead size, and your choice of cure rate, viscosity, green strength, physical properties, and color.

    Meets or exceeds the performance of characteristics of AAMA 802.3 Type II, AAMA 803.3 Type I, and AAMA 805.2 Group C.
