Research how much tonnage you need on your AC if you go with the spray foam. From what I understand you have to undersize your unit to make it run more. Help to remove the humidity.

If u have combustible gas furnace, h20 heater in attic n u make it a sealed system by spraying foam on rafters make sure u know what u are doing for make up air damper and have someone engineer it . I suggest not doing the rafters but doing the ceiling joists and walls or do walls with rock wool and ceiling joist with foam if u wanna get close results for 1/2 the price. I build high end homes for a living and that is how I'm doing my personal home I'm currently building. Walls rockwool, between floors 12" batts, ceiling / attic floor open cell foam . Also if you foam rafters is a pain in the butt if u ever have roof leak

true to c certian extent.... Now a days hvac companies are overtonning every new house so theydont get call backs .. Problem is that causes system/ ducts to sweat badly , so by under tonning it all you will do is have a warm house . What you need to do is under ton it and use a variable speed 2 stage system so you can either slow the fan down or speed it up depending on humidity levels. In our new house i under ton it , upgraded to a 16 seer variable speed system . After we move in i have a engineer that will come tweak the system and fans so we cab get around 27-31% humidity . Temp is not what make syou uncomfortable in a house it is the humidity . Currently to stay semi comfortable st my house im living in we set it at 67* which is cold but if we go higher it gets muddy and warm . So with our new system the plan is to stay around 70-72* but only be 27-31% humidity.

That's what I was wondering along with how it compared to cellulose and how is it as far as dusting and compacting over time

Rockwool and Cellulose are the same, then there is the blown in fiberglass and sprayed in Urethane Foam or whatever it it.

[fishinpox]

Rockwooo and cellulose are not the same, rock wool is much denser when installed and less likely to sag in the wall. Also cellulose is flamable ( they say it's been coated with a fire retardant but at the end of the day it's news paper..... Flamable) . Blown Rock wool is way to go , only down side is u have to wait about a week for it to dry before u sheet rock , they suggest only waiting a few days but I've found it still damp after 2 days so I wait 5-7 days. I'm getting ready to insulate 2 houses in the next couple weeks if you'd like u can come watch the process

My bad! :o

[southern151]

What is the cost difference in rockwool and say traditional fiberglass insulation going in your walls?

[weedeater]

Does it cause dust?

[fishinpox]

Cost is not quite double traditional batt insulation. Batt insulation is fine IF and only IF it's installed properly , and I have yet to see it installed properly in the past few years. As far as dust what dosent go in the wall gets vacuumed up n reused

Thanks for the info. I just want to make the right decision now not to regret it later. Still thinking of going with spray foam an be done with it. Got a bid yesterday on a 4 ton amana with heat pump. Two stage blower, 16 seer material and labor for 8k. Compressor has life time warranty and 15 years on labor. Not sure on amana though. Still gonna get a couple more bids but from what I hear thats a good price. Decisions, decisions.

Everyone will be in the same ball park on the a/c system, if the units are comparable.
The higher the SEER, the higher the costs.
Lifetime on the compressor in not bad, but they will probably up the price to pay for one later in the life of the a/c.
In the past 5 years, air conditioning has changed so much, it's hard to keep up if you are not in the business.

I had Chris Castile with C & C insulation do my attic with spray foam in May. I have 3500 sqft a/c'ed space and my electric bill last summer was running about $385 per month with last Sept being the worst ever @ $478. It hasn't been over $210 since. His number is (337) 302-4202.

That's a bad electric bill. If I saw one like that I'd kill myself. Lol. Thanks for the info I'll call him.

Funny how before I bought my current money pit I would have said the exact same thing. My neighbor regularly has bills over $450, but he has a pool and a pool house...
