Finished Room Over Garage Insulation 

Y’all have inspired me! I am looking at doing the same thing you guys did here. Great video! Looking forward to more, keep up the good work!

This was excellent in showing what you did and you made sure you got that air space under the roof sheathing so that the intake soffit air will passively flow up to the ridge vent....I did the same with the porch ceiling making it into a cathedral ceiling...1.5 inch air space....next project is the Attic, gambriel roof so lots of room up there. You said you insulated the floor...I guess in a home attic one has to not insulate the floor to allow for air from inside the home to rise into the living space of the attic ... but..you are above a garage so your attic floor is like the basement floor...got it....Thanks for making this vid. You gave me a better idea to use the left over rigid foam pieces instead of the 2 inch short wooden blocks and to use spray foam instead of screw with special washers to hold up the blue rigid foam. By the way, I had 3 layers of rigid foam each 2 inches thick . In Canada it gets cold here so R ceiling value is really important to make it high. 😉🇨🇦🍁

Great idea. Awesome video.

Good design. It’s amazing how many roofs don’t have the proper venting!

3 years later, how has it held up?

Thank you so much for addressing the air flow in this process! NOBODY addresses it on RU-vid. Is there any further videos or websites you could possibly point me to regarding this? Edit: Not professional advice - if you want some related information to go research: Ceiling Baffles - this is the product designed for roof air flow. You may also want to research how cathedral ceilings are insulated for additional research. Again, not advice, just sharing some information people may find interesting.

Great idea! It's almost 2 years later. Are you happy with it? Did it go as planned to keep the room temp moderated and the moisture down?

Was the soffit to ridge vent channel used to prevent heat in the formerly cold attic from melting snow on the roof which can lead to ice dams?

I understand the foam board and shims cut for air spacing is essentially same as a purchased, pre-formed baffle. Did you compute the cost difference of buying foam board, cutting and installing, compared to just buying baffles and then insulating?

How did the R19 work for you? What region are you in? Is it hot in the summer? Thank you for the video. I am trying to do this now and have been told I have to add extra 2x6's so I can put R38 in other wise the heat will be unbearable.

How did you build around the soffit vents to get the most airflow, without sealing them up or covering them?

where do the exhaust fumes car go?

do you need to use both the foam and the batt insulation though?

You’ve created a situation where you have two vapor barriers in each cavity because you’ve used faced insulation on top of the foam. This will eventually be problematic, especially if you’re dry-walling against the faced insulation. You should have done foam and unfaced or no foam and just used faced insulation. Also, don’t undervalue soffit vents.

The fiberglass batts are supposed to be stapled to the sides of the rafters

Maybe put those spacers on edge.

So, R-24 total? Don't you need R-30 or R-38?

Don't you now have a double vapor barrier that will causes condensation?

so good but id go tight to roof

👍👍🌹🌹

Its a baffle. Not a soffit.

Very sad the this information is incorrect Never have I heard of such a system. Professional 40 plus year builder. Best of luck in life to you.
