Special doors



Special doors – for very specific requirements
Novoferm offers a range of special doors to meet very specific requirements in property construction. The transformer door design ensures an adequate exchange of air in critical areas. By contrast, special prison or detention doors have to prevent this exchange. Soundproof doors also prevent exchange, since they ensure acoustic separation up to SV 48 dB.

Transformer doors optimize air flow
Our ventilation louvres are designed with a free geometrical cross-section of about 50% of the clear dimension, which ensures good air flow. On request, we can also integrate special fresh air grates into the door leaf and additional ventilators above the door if even faster exchange is required..

A new definition of "one-way" doors
Detention doors̈ are nowadays by no means restricted to prisons. We therefore manufacture steel doors with the typical features for even smallest-size series.
