Insulation

[jagsfans]

I have an attic space over my converted garage I need to insulate. My attic is a painfully small fucking place. I'm curious if anyone has opinions on Fiberglass over Foam Spray.

Foam Spray seems easier to install, while fiberglass is half the cost.

How about blowing it in. Around here, they loan you the blower when you buy the insulation from them. And you can blow it into very small spaces.

What about those newfangled plastic wraps?

Blow in cellulose is your friend. Just don't plug up your soffit vents.

Well you will get a tighter seal with the spray foam... do you just need to do the ceiling of the garage or the underside of the roof?

[jagsfans]

I don't know. I thought I would just need to coast the ceiling of the garage since it's already such a tight place.

What he said.

If it's above your garage, I assume it's a pretty small space. You might even be able to buy the bags and spread it without a machine....if it's really small.

Good luck bro.

Blow-in Teflon coated fiberglass. Doesn't break down. Not itchy. Stays puffy, hence higher R factor. Easily done. Much better than cellulose. Animals don't like it.


Did this to my attic a couple of years ago and my ground floor (basement to first floor) paid for itself that winter. I went with 18 in. and got an R factor of 50. in the attic. 6 in. in the floor R 20. Very tight space as well. Well worth it.

How expensive is this in relation to the blown in cellulose? Or is this a "You get what you pay for" situation?

You should use asbestos. I hear that works wonders.

Do you have ridge vents and soffit vents or just a couple of gable vents? As you have to make sure your garage attic is ventilated properly other wise you can have condensation problems...

The cost was about the same. Cellulose vs. fiberglass. I had it professionally done. I also had some crawl space spot that needed to keep the ventilation proper done with urethane foam. $2k for the total job.
