Liquid barrier

All doors can be designed with liquid retention barriers. The Liquid barrier has been developed in such a way that it does not affect the other properties of the door. This special liquid-rentention barrier adequately stops extinguishing water and/or hazardous substances. It not only ensures that no hazardous liquids enter the environment; it also prevents fire from penetrating and spreading!
The test in collaboration with Warrington has demonstrated that the losses through leakage are almost zero; 0.162 Litre per running metre per hour. (0.162L/m/h)
This unique solution ensures safe and certified application.
