Energy saving

A door that is needlessly open costs money! Every day, countless industrial doors stand needlessly open. This allows heat or cold to escape to the outside or to the next room.
Novoferm offers a reliable, safe solution to this problem with a range of high-speed sliding doors that close automatically after a preset time (on a timer). The opening is therefore closed at all times unless something or someone has to pass through it. This prevents energy being lost, which will have a direct impact on the amount of your energy bill.
