Where this material really wins is under roofs, which can become 100C or warmer, while you want to maintain 20C inside the house. They suck if you have 20C on one side and 32C on the other. Compared to bubble-wrap, it is unlikely to perform any different in an application like this, because of the low temperature differences. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
