The Powerhouse is a fast, safe and practically maintenance-free alternative, suitable for a wide range of exterior doorways. The engineered styrene butadiene rubber roll-up panel is virtually indestructible. It is designed without dangerous springs, high-maintenance counterbalance systems and wear parts, saving thousands on service costs. The patent-pending design and heavy-duty construction offer speed, wind- and pressure-resistance, and the tight seals required to protect critical equipment and operations. In the case of an accidental hit, the Powerhouse SD distinguishes itself from conventional doors by releasing without damage and restoring to full operation with just the push of a button.
