External fire spread
The Building Decree, the Fire Containment model and a number of documents related to the Dutch Environmental Management Act stipulate requirements aimed at preventing external fire spread (the spreading of fire through the ambient air) by thermal radiation. DGMR can carry out the calculations to substantiate compliance with the requirements. We use software, developed in house (Winfire ©), which calculates according to the method prescribed in the Building Decree (NEN 6068). We also have computer programs which can make calculations for special situations.
