Building codes often allow structures with window openings and combustible exteriors to be built with as little as 1.8 m (6 ft) of separation between them. In a recent full-scale laboratory experiment at the National Institute of Standards and Technology (NIST), it took less than 80 s for flames from a simulated house with combustible exterior walls to ignite a similar "house" 1.8 m (6 ft) away. In another experiment, involving the same type of structures, the flames from one simulated house again reached the second, but this time a gypsum barrier protected the simulated home from sustained ignition. The experiments showed that an adjacent structure can be ignited if flames from a fire inside a house exit through window openings. The experiments illustrated how a fire resistant barrier can, in the scenario tested, slow down flame spread between two structures separated by 1.8 m (6 ft).
