    Protect what's inside with WeatherBLOCK.

    If you need to protect what's behind your door, WeatherBLOCK is your best bet.

    By using WeatherBLOCK to seal your overhead or service door, you'll safeguard what's in your facility or garage from:

    • Extreme heat
    • Extreme cold
    • Light infiltration
    • Dust and particle infiltration

    Why is WeatherBLOCK the best commercial weather seal?

    WeatherBLOCK is a combination of Action Industries' two strongest sealing elements.

    First, we take our premium brush seal made with long-lasting filaments that won't hold water or freeze at sub-zero temperatures. Brush seal is remarkably efficient at keeping out drafts because of the barrier the bristles create when they spread.

    Next, we take the most durable rubber seal – an EPDM seal with a temperature range of -50°F to 300°F. This synthetic rubber is excellent at resisting weather, ozone, heat and UV rays.1

    Finally, we wrap the brush bristles and the EPDM seal around a steel rod and crimp them in place with a galvanized steel channel to make a metal back brush. The combination of a brush seal and an EPDM insert provides twice the protection for what's behind your door.
