What's your opinion of the worth of increasing attic insulation?
Does it really make a difference in heating and in my case, cooling efficiency and therefore electric bills?
Our weather this year has been extremely hot. I have a couple houses with AC systems struggling to keep up. They've been inspected, duct work upgraded as needed. I'm looking for ways to improve things overall for less strain on the air conditioning and improved efficiency for the tenants.
Extra insulation will run $300-$400 per property depending on sq footage. Just curious as whether or not it will really make a difference. --173.170.xxx.xxx

Yes... google "my Florida home energy" website it has lots of information on insulation for homes in Florida --24.231.xxx.xx

For the past 8-10 years every house I bought I added extra blown in insulation, then on existing homes, i added during turnovers. Even on a few I did the radiant barrier instead. Both products really help to keep that AC from running all the time. It's well worth doing. --75.141.xxx.xxx

We bought a house and updated it with a new AC system and spray foam insulation in the attic. The AC vendor said installing spray foam would lower the tonnage amt of cooling needed. I got by with one less HVAC unit by installing spray foam. Don't have a monetary value. But in my old house, I used radiant barrier and blown in insulation and could see my cooling bills reduced by $200-300 per month in the hottest months. --108.69.xxx.xxx

Thank you John. That was helpful. I know how insulation is supposed to work. I was just curious as to other's experiences as to how much of a difference it makes in the real world.
I guess I'm going to find out.
I typically add it when needed. Just not sure how much good it truly does. --173.170.xxx.xxx

On a 95 degree day, my well insulated in the attic Cape Cod was 85 degrees upstairs with no ac on. There is a large leafy tree just to the southeast though.
It's always a good idea to insulate an attic. --73.33.xxx.xxx

R40 to R50 in the ceiling along with R20 to R30 in the walls. Low E windows with argon gas do not absorb as much heat. Metal roofs with a light colour will not absorb as much heat as shingle roofs. Since installing a metal roof which has integrated vent on top of roof the house is a lot cooler even though the metal roof is a brown colour. It can get very warm here during the summer months. If had a net zero building there would no need for a heating or cooling system as the building is super insulated. --74.220.xxx.xxx

At 300 t0 400 dolars its well worth the cost.
And its an extra feature for the house when trying to rent it if tenants are paying the electricity bills.
Up grading my attic insulation was the singls biggest cost saver for me.
Just make sure your roofs are well ventillated to prevent shingle damage from the heat.
Contractors blowing in the insulation often dont care if they block the air flow for the roof vents. --70.30.xx.xxx

The baffle trays are very important to prevent the interior of roof decking from condensing, so easy and cheap I don't know why some crummy installers ignore this step but I see this a couple times a year, attic is kinda messy for blowin stuff, walls is real messy but the noise and hvac savings is amazing, I have a 2bd 750sq I rent to airline folks that I piled up 20 inches in the attic 2 years ago plus the walls - they say it is much better than the hotels regarding sound - but I don't offer continental breakfast. --76.188.xxx.xx

If it hasn't been looked at already, I think the best bang for the buck is to look at air sealing first.
From Builderonline: "the top five areas in a home that will provide the biggest return on air-sealing investment. They are:
—top plate to drywall at attic
Good luck! Bill --73.197.xx.xx

I installed blown in insulation a couple of years ago. It just took longer for my upstairs apartment to get hot. No noticeable improvement.
I was very disappointed.
This year I spent $10K on low e vinyl windows and see a huge improvement. --73.220.xxx.xxx
