insulation for a 1975 55' Kings Craft

[O.D.G.]

Hello all,

I just purchased a 1975 55' Kingscraft Aluminum houseboat. The majority of the walls have been taken down to the Aluminum walls. What product can or should I insulate it with? I plan on putting a bead board or tongue and grove over the aluminum walls.

P.S. I know nothing about houseboats

I personally would be looking at a spray foam.

I really would like to avoid spray foam due to cost and mess. I live in TN so we only get a couple of really cold snaps a year. more interested in stopping condensation. We're not living on it just for a weekend getaway. so if it's freezing I'll stay home lol is the old standby pink insulation ok or maybe the silverboard type?

the next step down from spray would be closed cell panels like the pink from HD or blue/green from Lowes. Thats what we use for basements and garages on coastal construction.
cut to fit between the metal studs, spray "great stuff" in gaps, and tape seams.

Unless you get a full bond, panels and batting will develop moisture between the aluminum skin and insulation. Moisture causes issues.
