Hörmann updates SPU 67 industrial door

09 June 2014

The new Hörmann Thermo SPU 67 is a further development of the recently introduced 50 series sectional door range.

Developed to meet the demand for improved thermal insulation, from operators and architects alike, the door features a 67mm deep profile that incorporates thermal breaks between sections, to offer even better U-values.


The improved insulation offered means that the SPU 67 Thermo door is set to replace the double insulated DPU door that has been the mainstay of the frozen and chilled sector.


The more compact, new generation door has the additional benefit of a more competitive price, making it an appealing choice for ambient as well as frozen and chilled operations. 


The double skinned steel doors with rigid polyurethane infill are offered in the same finishes and colours as the standard, 42mm thick, SPU doors to ensure uniformity of appearance.


The thermal insulation provided represents an improvement by up to 55% less energy lost in commercial properties.


Available as double-skinned, specially insulated steel sectional doors, and glazed aluminium doors with steel bottom sections that allow more daylight to enter or fully glazed aluminium doors for more light and transparency, the new particularly energy-efficient doors visually match the range of 42-mm doors. This means that on request, doors from both programmes can be installed in a building without affecting the appearance.


The thermal insulation value (U-value) is achieved for the SPU 67 Thermo steel sectional doors, thanks to inner and outer shells with a thermal break. In addition, the frame is separated from the brickwork by an extra seal, the ThermoFrame – a plastic profile – which, depending on the door type, provides for up to 21% better thermal insulation. 


Expanding the range, the partially (APU 67 Thermo) or fully (ALR 67 Thermo) glazed aluminium doors also achieve excellent thermal insulation due to a three-chamber profile technology, in which the external and internal profiles are separated by a plastic spacer profile. The standard triple Duratec glazing reaches thermal insulation improved by up to 40 per cent and is, according to manufacturer information, the only version in this form on the market with maximum scratch resistance and thus permanently transparent glazing. 




According to EN 13241-1, doors must automatically stop when closing if persons or objects are located underneath the door, and when hitting an object only exert a defined force or completely avoid contact, before travelling upwards again.


Power-driven Hörmann industrial doors are delivered with a photocell, an optosensor, integrated into the external seal as standard, which meets the EN 13241-1 standard.


Most energy is lost when doors are opened. In order to make sure that opening the entire door is not necessary for every pedestrian passage, more than 20% of the industrial doors are equipped with wicket doors.


Hörmann has developed what is said to be the first

wicket door with thermal break. The SPU 67 Thermo with ThermoFrame and wicket door still achieves an excellent U-value of up to 0.75 W/(m²∙K).


Concealed hinges and built in door closers are also included with this pedestrian access option.


An adjustable threshold profile with flexible seal compensates for any unevenness in the floor and double seals between the wicket door and threshold strip help to maintain the thermal capability of this design. 


Clear passage width is reduced slightly to 905mm for this new option, however the design retains Hörmann's trip free threshold. This combination of the low height stainless steel threshold strip and width means this wicket door can be used as a designated emergency exit.
