Abstract
The purpose of this report is to investigate an appropriate minimum distance between windows opposite each other to gain adequate protection against external fire spread. Studies were conducted of how external fire spread between fire cells through window openings occur. Studies were also conducted of how ordinary window glass can protect against such spread and how they react to fire. A model to calculate critical level of incident thermal radiation against window glass was created and its results were compared to those given in studied literature. Reasoning and discussion of uncertainties in the model are given in the report. Through analytical investigations, assumptions and calculations a design level of incident thermal radiation as a...

A model to calculate critical level of incident thermal radiation against window glass was created and its results were compared to those given in studied literature. Reasoning and discussion of uncertainties in the model are given in the report. Through analytical investigations, assumptions and calculations a design level of incident thermal radiation as a function of the distance between the window openings was formed. The development of this report led to the conclusion that the recommended separation distance between windows opposite each other in different fire cells is 5.0 meters, in accordance with existing regulations.
