I am trying to explain on my blog how we plan to insulate a house that will be built in the next year. I was wondering if it is possible to use images or free videos from Green Building Advisor on the blog. I wanted to ask before I did it.

I don't know how to use AutoCAD, haven't yet learned SketchUP so I might have to go the Lucas Durand way and draw these things by hand and then scan them in.

Thank you.

I just had my home insulation completed with 3/4 lb open cell foam. I am wondering if I need to spray a vapor barrier on it before I drywall. It is 10" thick on the roof deck.. do I need to spray that? Also has anyone thought of advantages to adding a reflective barrier on top of the foam? Last, does anyone recommend a fire retardent paint sprayed to the exposed foam on the roof deck for safety? I dont neccessarily want to complete any of these, but dont want to regret what i should have done after it is covered.
Thank you for any feedback -

A Mn based SIP maker (Enercept) told me they can make a SIP panel with integral ventilation under the outer layer of OSB. I was hoping for such a thing to help reduce the issue with rot at the peak of a roof SIP panel. Yes, interior air barriers are crucial as well, but it would seem that ventilation between the foam core and the outer layer of OSB would be helpful as well. One way they can do it is by grooving the EPS foam before applying the OSB. I think they have another way (firing strips). Has anyone used such a product and if so, what pros/cons did you encounter?

I am part of a volunteer fire dept in the NEK of Vermont and we are building a new firehouse. We want to build it as energy efficient as possible since it gets used seldom (hopefully). Just a little different from most homes around since it's only heated to 55 not 70.
Our plan is the following from inside to outside

5/8" Sheetrock
Poly Vapor Barrier
2x4 stud wall with fiberglass insulation
Double layer of 2" Green Guard staggered joints
2x4 stud wall with fiberglass insulation
5/8 Advantec Sheathing
Typar Housewrap
Vinyl Siding

I don't like it.

When those pictures of Dr. Joe's barn roof went up in another thread, I thought once again of the foam layers in my yard and wondered, once again, when I was going to start to see a problem.

Queensland is under water, the East coast of the US us being buried again by snow, cancelled flights and power outages.

It's snowing fast and furious here in north central Vermont (that's a 13" ruler on top of my side porch woodshed).

What's the weather like where you are?

I live in New York and have my woodshop in a 3 car garge (approx 20' by 25') attached to the house. The garage abuts the house on 2 sides. One of the other sides I beleive has basic fiberglass insualtion (2x4 wall) with 2 windows and the entire front are insulated firerglass garage doors. During the winter, it gets so cold in there that I cannot work. I have tried electric heaters, but they must run for hours before it is even close to tloerable and they obviously suck a lot of juice. I also tried Kerosene heaters, but the combination of the fumes and the moisture make it a no go.

I've got a very simple, steep pitch, vented gable roof, with soffit vents at the eaves.
I've considered standard gable vents, but want to keep my rainscreen detailing to a minimum.
I'd like to avoid ridge vents.
Does anyone have any advice or experience with soffit vents at the gable end?

Thanks for your help,

I was wondering, what would you all consider to be the "greenest" drain pipes? I'm not doing a plumbing job, but I was just curious.

I'm looking for water heater replacement options. Currently unit is a Takagi propane tankless. It's installed in the unconditioned attic due to space constraints inside the house. As part of insulating the attic with much thicker insulation, I need to move it from its current location and would need to re-run the vent if the unit is reinstalled, necessitating some new parts (this is stainless flue material, and fairly expensive).
