2012 27FB Cold Floor

[switz]

What I used was actually ¼" garage door insulation I acquired at CostCo and then found the aluminum tape at Home Depot. We have an 8" Rocky Mountain foam mattress and never heard or have seen issues with the insulation. I put a double layer on going 90 degrees different on the second layer.

However the day of gymnastics happening are long past.

I don't know why Airstream made that a pass thru compartment under the master bed on the 27FB model.

Any recommendations on how to properly insulate that storage compartment? I am assuming that is the reason the floor is so cold up front :-)

The main problem is that there is a spare tire well below the front floor section & no insulation, or even an enclosed airspace. So you have 5/8 of an inch of wood to go from "in the low 20's" up to a livable temperature. Wood has an insulation value of R-1 per inch, so basically you have nothing. The remainder of the floor has a layer of "Reflectix" style bubble/aluminum foil layer which Don, the tour guide at the Factory claims has the same insulation value as the fiberglass that filled the cavity in earlier production. This layer is only half the thickness of "Reflectix" which you can find at Lowes, & apparently has an R value of around 12, providing two layers are used, along with an air space between.
I would add a layer of rigid foam/aluminum foil on top of the floor below the bed, then add a layer of 1/4" plywood on top of the foam to support your "stuff".
Good luck,
Colin

The added weight of the plywood seems a potential issue, as does eventual compression of the insulating material due to the junk I toss in there. Is there any reasonable way to permanently apply insulating material (foam boards?) to the ceiling of the storage compartment instead?

The plywood only needs to be 1/4" & as it will be supported throughout with the rigid foam, you shouldn't have any issues unless you put an anvil in there

Hi, jumping in with dumb question, in the Summer do u remove the insulating bubble? I understand need in cold weather and infact we use dinette bed too so i will tape some under those cushions, but how is that with Summer heAt? Thanks in advance, nothing I like more than. Moving a corner matress around. I will have to fashion a little trap door to get to plumbing.

It should help to keep the "cool" in during the summer. It's a "win win"

Oh well then I am on it, seems like easy fix, couple rolls , lay layer one going east and west, tape down, then lay next north and sourth, make door to get a pipes, seal around edges with aluminum tape and i've got myself a mod. Will do dinette seats too. Easy peasey.
