The last and most important thing to be installed was the floor.
There had been concerns about putting in insulation. It was a great idea to
prevent heat from coming in, but we had read about others having problems with
squeaking from the insulation rubbing against parts. Our remedy .... GAPS! Not
just for the insulation but for the wood frame. We left about 1/4" between
the plywood, lumber, insulation and bus frame.
One thing we give gaps
was the paper we layed on the entire bus floor's metal frame. For that we used
roofing paper and made it overlap the walls by about 2".
Here was our floor
construction:
- 1st layer = 30# felt roofing paperSdf
- 2nd layer = 1/4" plywood
- 3rd layer = 1x3 lumber framing with ¾” insulation board sandwiched inbetween
- 4th layer = 5/8” plywood
We layed all the paper
and 1/4" ply first. Sometimes we had to cut off as little as 1/2"
from the plywood so that the edges would end up in the middle of the bus's
metal frame below. If Michael hadn't had the foresight to mark up the frames'
location along the wall panels, we would have had a hell of a time trying to
guess where the pieces were. Thank goodness for his genius!
We started at the front
of the bus, which is the hardest, most intricate part. In addition to cutting
around the wheel wells, we had little notches for frame pieces to consider. We
actually had to redo this first piece because it just wasn't fitting well and
fitting straight. We hated to waste material, but we were getting frustrated
jiggling and wiggling the thing in. I'm glad we saved our sanity at the cost of
another sheet of ply.
After those first 2
layers were complete from the front to to the end of the bus, came in with the
laborious 3rd layer and 4th layers that required a lot of measuring and
cutting.
Once we had a section
cut and tested, we glued it onto the 1/4" ply with construction adhesive.
There were two types, one for the wood and one for the insulation. Who knew
they needed their own glue!
Immediately after the
3rd layer was glued down, we put more glue on top of the pieces and laid a
(precut and pre-tested) layer of 5/8" ply on top. The rain barrels
(recycled 5 gallon buckets) Uncle Frankie had left out for the chickens came in
handy as they were placed on top the entire sandwich of wood and insulation so
that the adhesive would dry with the pieces in the correct place. Don't worry
PETA, we left some barrels of water out for the chickens to stay hydrated.
