While roofs, walls and windows have been insulated for decades, automatic sliding doors still exhibit significant and continuous heat exchange. This takes place even when the doors are fitted with insulated glass and are in the closed position. This is due to the normal one-piece aluminum profiles used in the construction of the doorframe for reasons of stability.
The high thermal conductivity of aluminum means that over the entire surface of the door profiles, heat escapes outwards, or, in an air-conditioned room, ambient heat simply radiates away. The record THERMCORD system has been specially developed for automatic doors to reduce heat loss.
This is achieved with the construction of two non-touching insulating layers within a slim profile that is hardly discernably thicker than regular doors. Moreover, because these two V-profiles do not touch each other at any point inside the door, any heat exchange between the inside and outside of the door system is prevented. This reduces heating costs by eliminating any hidden, permanent outflow of heat. The opposite also applies – heat is prevented from entering, thereby preventing indoor air at lower temperatures produced by costly air-conditioning from escaping. The result is a stand-alone design that sets new standards in form and function. A thermal value (UD) of up to 1.4 W / m² K is achieved in conjunction with 30 mm double glazing.
The record THERMCORD is an automatic door system that has thermally separated door profiles with heat insulating properties. The ift Rosenheim determined an achievable heat transmission coefficient (UD) of 1.4 W / m2 K featuring approved insulating glazing. THERMCORD is employed as an inside or outside door in areas with, even temporarily, a high-temperature differential.
THERMCORD has been developed entirely in-house – from the original idea to market introduction. The in-house development has allowed us to focus on and implement specific features which are of particular importance to the use as a door system. Barely distinguishable except for its thermal performance, THERMCORD can be subtly incorporated into your global concept and is therefore perfectly suited to replace old installations and complete conventional door systems where a more temperature efficient solution desirable.
record THERMCORD RC 2 / RC 3
record THERMCORD RC 2 / RC 3 is the ideal entrance door for your retail store, hotel or office building. You will receive effective burglar resistance in combination with efficient, energy-saving properties, which reduce your heating and air-conditioning costs.
The THERMCORD RC 2/RC 3 is particularly suitable for break-in protection since the door frames are designed to be extremely strong to ensure thermal separation. Two intertwined, V-shaped profiles ensure a level of sturdiness that provides immense resistance to attacks by burglars. Moreover, because these two V-profiles do not touch each other at any point inside the door, any heat exchange between the inside and outside of the door system is prevented.
The record THERMCORD+ profile system, has a striking range of features designed to reduce climate control costs, 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.
record THERMCORD telescope
record THERMCORD telescope is an automatic door system that has thermally separated door profiles with heat insulating properties. The ift Rosenheim determined an achievable heat transmission coefficient (UD) of 1.4 W / m2 K featuring approved insulating glazing. In conjunction with matching insulating glazing and corresponding side panels, the THERMCORD telescope is primarily used as an external door in areas where – even temporarily – there is a high temperature gradient and the space conditions are not optimal.
The THERMCORD telescope is the first telescopic sliding door with thermally insulated profiles that can hardly be distinguished from standard profiles in size. Its filigree construction makes it possible to combine architectural wishes with energy requirements, even in tight spaces.
