Semi-insulated technical doors
For separating medium-insulation, high-traffic production and food industry areas. Where a 40 mm polyurethane core provides optimal climate control without unnecessary investment cost or excessive structural weight.
Rational energy management and space separation
In industrial and food processing facilities, transitional zones often appear between processing rooms, packaging areas and distribution corridors. If the temperature difference between spaces does not exceed 10–15°C, a semi-insulated technical door is the optimal solution.
Semi-insulated technical doors are typically manufactured with a 40 mm thick door leaf injected with high-density polyurethane (PUR) foam. This thickness provides excellent mechanical stability while ensuring draft-free closing.
The lower self-weight significantly speeds up opening and closing cycles, reducing physical effort during manual material movement. Smooth, rim-free stainless steel surfaces fully support HACCP requirements.
Lightweight construction with uncompromised industrial strength
Lower moving mass
The 40 mm PUR foam filling gives the door leaf sufficient rigidity without making operation heavy. It is an ideal choice for intensive use with hundreds of opening cycles per day.
Draft-free and dust-free closing
Thanks to the special door leaf edge design, the system provides air sealing between frame and leaf even without rubber seals, helping to prevent cross-contamination.
Maintenance-free operation
For hinged doors we use stainless steel fittings; for sliding doors, industrial POM plastic rollers are used, which also resist aggressive cleaning chemicals.
Technical parameters
| Door leaf thickness | 40 mm |
| Insulation material | High-density injected polyurethane (PUR) foam |
| Surface quality | Food-grade coated steel (RAL 9010) or WNr. 1.4301 / 1.4404 stainless steel |
| Opening type | Single-leaf or double-leaf hinged door, or industrial sliding door execution |
| Recommended environment | Positive-temperature spaces above +10°C, preparation rooms, corridors and clean areas |
Typical application areas
Raw material preparation and packaging areas, seasoning rooms and spaces where washable surfaces are expected.
Dispatch zones of chilled halls and corridors separating office blocks from operational areas.
Separation of serving areas and back-of-house storage where trolley traffic is present.
Where dust-free operation and easy cleanability are primary requirements.
