Basjoo: No frost - no die! The leaves may even survive quite nicely a short dip
below 32^F. The rest is dependent on thickness and duration. I leave my Basjoo
usually unprotected until there is serious damage to the leaves and that takes
often several nights when the temperature goes down to about 25^F. It all depends
on the duration. I would not give any guarantees, if the temperature remained for
8 hours or longer at 28 to 30^F. The cold needs time to penetrate to the sap to
crystallize it, to break the cells from the inside. If a few short frost periods of 25^F
were all, you would lose a few leaves and the PS would just produce new ones,
because the frost had not enough time to penetrate into it and the plant would carry
on.

That is it for basjoo! I have no experiences, with other bananas. Several tropical
plants die at temperatures above freezing, if they are exposed to them for a while,
because their sap gels and the internal infrastructure can no longer function. Some
bananas may well belong into that category.

As far as basjoos are concerned, a tempory minor drop below 32^F due to heating
failure is nothing to worry about, even if you should lose a few leaves.

Good Luck,
Olaf
