Utilized Technology

Lindab duct systems consist of round and oval, single and double wall duct systems including silencers, dampers and grilles. Our round duct systems are equipped with
Lindab Safe EPDM double lipped gasket seals rated to 10” static pressure. This leads to shorter installation times, less weight, fewer air leaks and a smaller insulation surface as well as lower energy consumption. In addition, there are the major advantages for the installation contractor of having locally stocked and standardized products. To complete the spiral line we offer Flat Oval pipe & fittings, along with Insulated Round & Flat Oval pipe & fittings.

Gripple Hangers are universally recognized as the world’s fastest and most cost effective hanger system. The product is used for suspending and bracing of ductwork, piping, electrical and architectural components, as well as Seismic design restraint devices. Gripple Hangers are used on major projects worldwide, covering industrial buildings, distribution centers, schools, hospitals, warehouses, and retail stores. In fact, they can be found in some of the most prestigious projects around the world.
