View Full Version : insulating a shed

03-19-2011, 12:50 PM
I recently built a 12 x 16 shed on a 4" concrete sled. Put a 6' x 7' roll up door in it. I did insulate the ceiling with 4" fiberglass insulation I had left over from a previous project. Roof does have vents and vented sofit. I plan to keep my rider mower, push mower, tiller, etc, in it year round. Temp extremes are 100+ in summer and -5 in winter. Question is, should I insulate the walls. I am putting 7/8" OSB on interior walls. Exterior is OSB, house wrap, and vinyl siding. Didn't know if the hollow cavity between interior and exterior could develope moisture. please advise, thanks!

If its not heated or people living space why insulate it?

You may notice some condensation with extreme swings in day to night temps. in season changes but they would be too few to worry about.
