Frequently Asked Questions

  • How does this door work in high winds?

    Our base doors are rated for 75mph wind loading and can be upgraded to 120mph. All doors are fully operable in wind conditions up to 35mph.

  • What sizes are the doors available in?

    Our doors are custom built to fit the building opening with sizes ranging from 35’ wide to 145’ wide with heights up to 50’ tall being available.

  • Are there different colors available?

    White is the stock and recommended color for our doors. The white color allows the curtain to maintain a translucent effect and allows the most light to filter into the building. Other colors are available at additional costs but are not highly recommended.

  • How long will the curtain material last.

    The average life expectancy for the curtain is around 12-15 years. However, we have replaced curtain that have been in service for over 30 years.

  • Is this a new product?

    No. Our doors have been in service for over 30 years, with some of the first units installed in the late 1960’s.

  • Can this door be used in any climate?

    Yes. Our doors are in service all over the world. In cold northern climates the ice and snow do not stick to the door so it remains serviceable in all weather conditions. In warm climates the doors can be opened partially to allow cool breezes in while blocking the afternoon sun.

  • Are these doors available outside the United States?

    Yes. We have shipped our doors into Canada, South America, Australia and Afghanistan.

  • Can the door be manually operated?

    Yes. All doors are supplied with electric operators and controls. Each door is also supplied with an emergency hand crank for each drive to be used in the event of a power failure.

  • Does this door seal well?

    Yes. Our door has the fewest number of required sealing points of any product available. While most doors require a moveable seal at the top, sides, bottom and through the middle of the door; we only require seals at the sides and bottom, the top is a solid attachment and the opening is covered with one complete sheet of material.

  • How much does the door weigh, and what loads does it impose on the end walls.

    Our door weight is negligible when the header of the building is designed to accommodate the wind loads that will be transferred to the building. This information is supplied on the “Lintel Load” chart with the door specifications. Please consult the factory for details.
