Insulating Shake Shingle Walls (No sheathing!)

Vosseller_CottageApril 11, 2011

Hi all,

Another insulation question, I couldn't quite find what I was looking for in previous threads. I have a 1920's shake-shingle cottage. Most of the house is shake over planked walls (lath and plaster interior). However, there is an uninsulated 12'x12' addition that was built around a stairwell of sorts leading from the kitchen to the basement. Lot's of wasted space, so I'm going to reconfigure it and make it more useful. I also lose heat from the kitchen to it.

The walls of the addition consist only of shake nailed to horizontal strips about 12" apart (no exterior sheathing), I can see the shake from the inside. The interior is finished with a cardboard like material. I plan to sheet rock the interior, but I'm clueless how to insulate these walls. Should I put some kind of barrier between the studs, before I insulate? Otherwise any water that get's between the shingles will wet the insulation. Suggestions on type of insulation (I live in New Jersey)? Advice appreciated. Thanks!

p.s. Would the same apply to exterior walls WITH planking?)
