Garage Doors & R-Value

Recommended Posts

Anyone have a recommendation for R-value on a new garage door? I'm trying to decide on how high to go; I've got options ranging from 12 to 15 to 17.8. Is the 17 overkill? I'm inclined to go as high as possible, but there is, of course, a cost difference.

What are the cost differences? I have never priced the insulated ones.

Are you planning on air conditioning the space?

Off the top of my head, i think i have 2 $1700 - $1800 bids; one for a R-10 and one for an R-15, then one for $2300 for the R-17.5. Home Depot came out to $1800 for an R-17 model, but i would rather go with an actual door company, although that's not a guarantee of better quality installation.

My garage is not air-conditioned, but is attached to the house. R-Value is one of the few characteristics that stood out to differentiate the multiple models/vendors.

You'll save more money on heating/cooling costs by making sure the door between the garage and house is insulated and weather stripped than buying an insulated garage door for an unconditioned garage.

You're just going to create a heat reservoir. The insulation will decrease the rate of temperature rise/fall in your garage, but it will not ultimately decrease the max temp.

So at 6:00 p.m... the heat from an un-insulated garage can start escaping as the outside temp begins to decrease... meanwhile, in your house, at 10:00 p.m. at night - it's still 95 degrees in there.

Take Red's advice.
