Pictures of cold rooms?

Never guess. Look it up, then you won't have to open your mouth to change feet.

In my post above I assumed that cork insulation would have properties much like other forest products. 'Tain't so. Cork is in U.K. fire class B2 which means "extremely fireproof. A class A material is incombustible while a class F means it burns like a box of stick matches in Hades. This fire retardant nature is retained by cork granules typically poured between the walls of cold rooms and such in the early 20th century. So, the timber walls of Titanic's cold rooms might burn, but not so the cork insulation.

What's odd is that cork dust burns with a hot flame. Back in the day dust was used to fire boilers to power factories that made cork products. And, cork dust has been added to some explosives. Not to say that cork doesn't burn, it does. The kindling temperature is above 200 c (392 F)

Another property of cork insulation is that it is considered "unattractove" to mice and termites. Now, termites are not much of a problem in a steel hull vessel, but mice...well they might just like to gnaw on some of the contents of a cold locker. Cork is also waterproof and resistant to damp and rot, according to the manufacturers.

And...it floats.
