Here you will find a range of questions that will hopefully help to answer any queries you may have regarding Hart Doors, our products and services.

Benefits Of Hart Doors

  • Q: Are fabric doors wind resistant?

    A: Not all high-speed doors are suitable for external application due to varying wind pressures in exposed locations. For these applications, it is important to get a door fit for the job. Our Speedor Storm is designed with this in mind to class 5 wind resistance.

  • Q: How do fabric, high-speed doors save money?

    A: Reducing energy usage is not only vital for the environment, but it can directly benefit your business and your supply chain by reducing costs. A well-insulated and low-maintenance high-speed automatic door can reduce energy consumption by minimising draughts, maintaining internal temperatures, and optimising traffic flow through their high-speed automatic operation. 

  • Q: How long will my Hart doors last?

    A: The expected life of our high-speed doors is over 20 years and 500,000 cycles in normal conditions. Having recently replaced a door after 34 years we can attest to the quality of our engineering. Fault rates are low, and when repairs are required, first time fixes are high. Due to the longevity of our doors, the total cost of ownership is low. 

  • Q: Why should I buy a door manufactured in the UK?

    A: Apart from the quality manufacturing to ISO 9001: 2015 and material audit trail guaranteeing the quality of the components, we can also offer faster delivery times, spare part availability, manuals in English and superior aftercare that you can’t get from products manufactured elsewhere.
