Title: Bus convertion #9 installing new sub floor.
Post by: mike802 on October 24, 2011, 08:21:40 AM
I finally have the new sub floor in, finished it in August, but just couldn't get around to editing and posting the footage.  I have accomplished a few other things since getting the floor in, I will get that up as soon as I can.

Good job Mike. Just curious, Why pink board vs fiberglass. Especially in those odd shaped places. Is fiberglass inferior?

Thanks Kodydog:  Foam board insulatiion is supperior in a moterhome aplication for two reasons.
1- Pink board has a higher R value pr inch than fiberglass and with limited cavity space in the floor, walls and ceiling we want to get the highest R value possible. Spray in expanding foam has an even higher R value than pink, or blue board, but only slightly and the extra cost is significant.

2- Foam board in impervious to moisture, fiberglass soaks it up and once wet has no R value what so ever.  A motor home environment in pron to condensation because of huge temperature and humidity changes, so the foam board is good insurance even if preventative action is taken to protect the motor home from condensation.
