I have a 1000 square foot cottage which has insulated floor and walls, but the roof has never been insulated. The roof rafters are 2x6 construction, and when looking up at the "ceiling" of the cottage, the sheathing can be seen from the interior. That is to say that the ceiling is "vaulted" over the entire cottage, and is unfinished. It has been suggested to me that I install soffitt vents and a ridge vent, and then insulate and finish.

Any suggestions what type of insulation to use for this, and how to proceed? Incidentally, I live in the northeast, and I'm not neccesarily trying to make this a year-round-use cottage.

Thanks to anyone who responds!

What has been suggested to you will work, but the process leaves out a crucial element:

continuous rafter vents from soffit to ridge.

Without installing continuous rafter vents from the soffit to the ridge, any insulation tuffed between the rafter will simply block air flow and encourage condensation.

The maximum insulation amount you can get with this design is about an R-21 compressed fiberglass made for 2x6 rafter installation.

If you require additional insulation, you could consider building a sub-ceiling below the existing rafters at a slightly less pitch slope than the current roof. This is similar to framing with 'scissors trusses'.

This will allow you to install thicker batts of fiberglass in your roof rafter area.

Even with the 'scissors truss' type deisgn you would still need soffit, continuous rafter and ridge vents in most cases.

Thanks, homebild. Are you referring to those wafer-thin, styrofoam sheets for installation before the batting?
