A NorDan External doorset is solid
Noise can be a big nuisance and to reduce sound levels between outside and inside, might be essential for well-being. The need for external doors with high demands on sound reduction is therefore all common.
External doors with great sound reduction.
NorDan exterior doors can be supplied with the following sound classes: Rw 38dB and 40dB Rw.

The market's most solid door?
The additional climate package on all our doors means that we can proudly say that we produce Scandinavias most solid doors. This shows the latest tests carried out at SP Swedish National Testing and Research Institute.
- Highest Class - E900, for waterproofing according to EN 12208, means that the door without shielding above, manages 900 Pascal with air and water pressure without leaking out. 900 Pascal corresponds to a wind speed of approx. 36 m / s or 130 km / h.
- For air leakage between the frame and door leaf, in accordance with EN 12207, test results have also shown that the door meets the highest class, Class 4 with a pressure of 600 Pascal.
- NorDan exterior door has also managed a storm safety test at 1800 Pascal.
Density between the door leaf and frame are important in proofs to measure air leakage in the house. NorDan exterior door contributes to a better test results.
