Groundbreaking technology for the construction industry.


Danish Wood Technology A/S has developed and patented a breakthrough technology that fully impregnates wood with both fire safety and extreme durability as a result.


With DWT´s new process for wood impregnation, it is possible to achieve full impregnation with both water based and oil based liquids. This opens up for the use of non-toxic impregnation formulas.

The DWT process also provides full impregnation of hardwood, as for example mahogany, oak and heart spruce.

The DWT process uses a mix of vacuum, pressure, and high frequency, to open the structures in the wood, this method permits the preservation agent to penetrate into the heart of the wood from different directions.

Apart from the improved durability of the wood and the economic benefits it provides, the fire retardant properties gives architects new opportunities to realize their vision in designs of buildings.

A plus for the environment 

Since a DWT-treatment prolongs the durability of the wood extensively, the amount of wood to be cut down in the future will be reduced significantly as well.

All in all, this means that wood treated this way can be used with a clear conscience indoor and outdoor.
