Habitable attic with no soffits

outbreak187's picture

Hello Everyone!

 

I am your average lurker sorry, I finally got some guts to register and ask a question! I have searched the forum and could not find a solid answer to my problem. I have an habitable attic with no soffits. I'm looking to renovate the two bedrooms and the bathroom located in the attic. After ripping all the old walls out I would like to insulate it. And here is the problem, I do not know how to go about it as I believe there will be no adequate air circulation after I insulate it with batt. Also I would like to install some recessed lights there as well. What would be my best option for insulatio? I'm also on a tight budget and all the work will be done by me.

I really appreciate all the inputs!!

Thank You!!

This is a tough one. (post #206889, reply #1 of 7)

You have limited experience, you studied the forum and found nothing exactly like you have, you want to do something but unsure what and have limited funds.

Outside of not knowing what climate you live in, I'm sure there's a bunch more questions we could ask.

Hello,

I guess my experience is indeed limited; however, I know I can do what needs to be done with my own hands. I know you know what you are doing Calvin, but I simply can not afford to pay to get it done by a contracto. I'm in NJ so it probably makes it more difficult. The attic is finished now and it has been for fifty years I would just like to make it better insulated.

Thank You

Ok (post #206889, reply #4 of 7)

Now we're getting started.  The climate is NJ.

How deep are the rafters?

How do they sit on the top plate of the wall?

When was the roof done?  could you take the insulation on top of the roof-stress skin panels?

Are there knee walls?

Gable or hip?

Are you going to rewire?

Is the plumbing sound or are you redoing that down to the drain in the basement/crawl?

Adding windows or changing them out?

 

There's absolutely nothing wrong with doing it yourself if you have the qualifications.  Some folks show up here and think this work is easy..............anybody can do it.

I do not mean to deflate your desire.  Best of luck.

So,

We did not take down the walls yet but I might be able to get in there soon to check few things.

Rafter size = have to verify.

How do they sit on top plate = have to crawl in to check.

The roof probably in the last 10 years. So doing SIPs would mean taking down the whole roof including plywood, it's an option but really a last! Resort!

Knee walls present.

Gabble.

Will most likely rewire as it has no ceiling lights.

Plumbing is staying.

Full finished basement.

Windows are staying for now.

 

Thank You!

Where you live, you need between R38 and R49 in your attic.  Cellulose is the cheapest to install (and usually the best option too), but it is only R3.5 per inch, which means you need between 11 and 14 inches of cellulose.  Foams can get up to 6.5 an inch, you can buy them by the sheet and cut them to fit, or fasten them to the underside of rafters with cells blown behind.

YAY!  I love WYSISYG editing!  And Spellcheck!

You have an uninsulated attic (post #206889, reply #7 of 7)

You have an uninsulated attic built at least 50 years ago.  Odds are the rafters are no deeper than 6" and may be only 4".  Not a lot of room for insulation without taking away a significant amount of headroom.

Basically, there's no good (post #206889, reply #2 of 7)

Basically, there's no good solution to your problem.  Vaulted ceilings in general are a problem, and the lack of soffits makes it worse.  There are several expensive solutions (involving foam), but doing the job with more conventional materials is difficult to impossible.
