Great suff, There is a special blade for trimming flush with studs but I've used a bow saw with acceptable results for smaller projects
Wow. That stuff is expensive but it pays back quick !
You're going to love it Chris!!!
It's been a while. I was in hopes there would be more pictures to follow.
That's what we used. Makes a big difference.
sorry about the lack of pics, but we have hit the stage of building that is not so exciting. Plumbing, electrical, and mechanical. I haven't gotten brick started yet due to the cold weather.Quote:

That looks like it's gonna be a very efficient tight house......... Has your mechanical contractor talked with you about installing an ERV to ensure the house is ventilated properly?
yes, I know about the fresh air returns systems. If you have a completely foamed house you must ventilate it properly. I am not doing a completely foamed house. My walls are foamed but my attic is gonna have traditional blown in insulation. Probably gonna have an R44 up there. The reason being is that I have an extremely tall, complicated, and cut-up roofline. I was kinda scared to foam between the rafters and maybe not be able to tell where any future roof leaks may be located. The cost of foaming a big tall attic was another factor. The way I have it figured it would take about 10 years or more to recoup my cost, by then who knows what will be available. The way I see it, if I can't recoup my money within 5 years it's not worth the trouble, BUT, I have been wrong before.Quote:

I have heard a lot of positive feedback about installing reflectix on the bottom of rafters, really cuts down the radiant heat load in the attic.
Plus if a leak is suspected sections are easily removed for inspection.
I'm interested in this reflectix. May be something I need to install.
Foam will help you a lot more in attic than walls.... Walls are a minimum gain. Especially if your ductwork is in attics. We do 20-30 new houses a year and have tracked every form of insulation you can use. If you can squeeze the open cell in the attic in your budget you will not regret it.
Our lake house is 3200 sq ft with open cell everywhere. We average 150 power bill year round. That's using 13 seer heat pumps with variable speed air handlers. And 30 a month is the underwater light. You do the math, open cell works.

All my utility bills combined didn't equal my water bill this summer (3 acres of irrigation). We have averaged less than $175 a month from April until January on electricity and natural gas combined. It is just unbelievable.Quote:
