My family wants to insulate the ceiling of our cabin. It gets unbearable in the summer sometimes. The walls were done but the ceiling never was!?!? I was just wondering what would be the best way to do it. What kind of insulation? The foil stuff or what. I was going to get a mid range R value pink bat. and then just staple up poly for the vapour barrier. We don't want tp put up any drywall or paneling this year $$$$ I want to know the most economical yet functional route.
Hi Buely,
If I can 'imagine' what you have, you have an ATTIC w/o a floor, if you know what I mean. In other words, you have a roof that ISN'T vented.
Yes, this is bad news. ALL that heat is now 'pushing' its way into the living space. There's only one way I know of to fix this problem, and it's the right way.
Since you have an 'exposed' ceiling, you need to add soffit or eave vents, then 'install' a true ceiling. After the ceiling is installed, the 'cavity' between the vents and the ridge will allow for ventilation. Yes, you'll need a Ridge Vent too. The Physics here is that air will enter in the Soffit/Eave Vents, rise up and cool the underside of the roof, and push out any hot air through the Ridge Vent. This process will happen naturally so you needn't assit it.
I am assuming that you have rafters on the underside of your roof, and that your roof is an A-frame type roof; not a flat one. A Professional Contractor can estimate the job for you and tell you what needs to be done.
If this won't work for you, post back w/more details. My best to ya and hope this helps.
