Tammer doors are tested for the realities of Nordic weather

Tammer has successfully completed climatic testing of its steel doors in accordance with:
🟣Behaviour between two different climates for an external door: SS-EN 1121:2000

The tests were carried out by RISE Research Institutes of Sweden, an accredited and independent laboratory.

The following models were tested:
🟣 SMU101 (EI30/EI60) & SMU110 (EI120) type single leaf doors

Under both Climate B (+23°C / +13°C) and Climate D (+23°C / –15°C), the doors achieved:
✔ Closing force according to SS-EN 1026-2016: Class 4 (EN 12217:2015)
✔ Climate resistance according to SS-EN 1121:2000: Class 3 (EN 12219:2000)

These results confirm that Tammer doors maintain performance and sealing even under strong temperature differences, making them highly reliable for cold and changing Nordic weather.
