Energy-saving overhead doors with favorable ROI

With industrial Crawford overhead doors from ASSA ABLOY Entrance Systems, companies can drastically reduce their energy loss. Up to €12,000 per door over a period of fifteen years. This means that the investment often pays for itself within a few years. According to marketing and communications manager José De Ruijter-Luken, the doors stand out because of the versatility of the range. “We offer a wide range of variables: different thicknesses, seals, windows, motors, and control units. These combinations allow you to put together countless configurations. Customers also appreciate the fact that we can use our own calculation models to calculate in advance how much energy a door will save in their specific business situation.” 

The standard OH1042 overhead door is available in various versions with normal, double, or even quadruple opening speeds. With the latter option, the door opens and closes at a speed of no less than one meter per second, resulting in significant energy savings. Calculations by the European Door and Shutter Federation e.V. show that the opening speed of overhead doors has the greatest impact on energy loss in a warehouse. For less frequently used passageways, the extra-insulated 82 mm version is ideal, as its thickness optimally maintains the thermal envelope of the building.

Overhead doors and sustainability goals

In order to achieve optimal insulation, Crawford panels consist of CFC-free polyurethane filling without thermal bridges. ASSA ABLOY also uses seals to ensure water and air tightness. Thanks to sealing technologies, together with improved U-value performance, ASSA ABLOY doors contribute to companies' sustainability goals. Following the EU Green Deal and stricter reporting legislation, companies are looking for ways to save energy.

Favorable ROI

The favorable ROI of Crawford doors is evident from practical calculations. A growing distribution company in North Brabant with a warehouse area of 50,000 square meters wanted to manage the increased traffic and reduce energy loss. Replacing the old doors with the fast ASSA ABLOY OH1042S overhead doors has created a more efficient workflow and reduced energy loss. In addition to the efficiency improvements, the company can save €830 per door per year in energy costs compared to a normal door. The additional cost of a high-speed door compared to a standard door is therefore often recouped within a year. An energy calculator can be used to calculate the savings for any company.

Greater efficiency

Although energy savings are key, Crawford doors offer even more advantages. “With every door we develop, we keep a close eye on five aspects: efficiency, reliability, durability, visual appeal, and ease of use. For us, efficiency means more than just improving workflow. Increasing safety and reducing dust and noise are also important features of our doors,” says De Ruijter-Luken. She continues: “We also want our doors to look aesthetically pleasing and do what the customer expects of them. Malfunctions are therefore easy to remedy, and if something is accidentally damaged, the individual sections can be easily replaced. In addition, we offer countless options for operating the doors: with buttons, radars, a mobile app, or via computer. In other words, plenty of ease of use.”

Advice per company

Anyone who wants to know exactly what a door can mean for their building can always contact our advisors without obligation. “Every situation is different,” emphasizes De Ruijter-Luken. “That's why we supply directly to users and owners, without the intervention of dealers. We have deliberately placed the contact details of our specialists prominently on the website. This lowers the threshold for companies to discuss their energy issues.”
