record THERMCORD+ – automatic sliding doors with integral thermal insulation

The record THERMCORD profile system, with its striking range of features designed to reduce climate control costs, was introduced for the first time in 2012. The THERMCORD+ continues to apply this idea by using active seals.


Pressure differences between the inside and outside of large buildings are common, and inevitably lead to considerable suction, allowing cold, heat and dust to get in, but also cooled or heated air to escape in an uncontrolled manner.

With the door closed, the active sealing system patented by record stops all suction, and achieves air permeability values which, for sliding doors, are exceeded only by special products for use in operating theaters or clean rooms.

While the main and secondary closing edges are equipped with conventional sealing systems, the sides at the top and bottom feature newly developed so-called active seals. Active seals make it possible for the door to open with no resistance to disturb the smooth running. At the end of the closing process, a carefully designed mechanism presses the sealing profile, which is located in the bottom edge of the door, to the floor. In addition, an integral sealing lip descends at the door upper edge along the full width to close the remaining gap between the door leaf and the drive housing.


  • To divide different temperate zones with high temperature gradients
  • To prevent suction effects with its innovative, active sealing system
  • To significantly reduce energy loss when the door is shut
  • Can be used both inside and as outside doors

Can be retrofitted to THERMCORD systems

Active seals can be retrofitted to all automatic door systems with THERMCORD profiles already installed. With relatively little effort, the result is a fully functional record THERMCORD+.
