foam insulation and ERVs

We are beginning the process of building a new house. I'd like to use foam insulation and I understand that when doing so its recommended we have a ERV installed.

I have two questions:

1) Is there any evidence of health hazards associated with foam insulation?

2) how reliable and easy are ERVs? That is, so they work pretty well on their own (except for replacing filters and the like) or do they require tinkering depending on conditions?

There are many different types of foam and methods of applying and using them. What are you considering?

EVR's are also known as "air to air heat exchangers." There are links on the above website.

If you really want to use foam insulation, read up on SIP's, also on the same website.

I didn't realize there were different kinds of foam insulation, although that makes sense.

I'll do some research on the website.

this sounds like its going to be complex, but a fun project.

thanks to you both.

Foam is definitely superior to any other insulation on the market. It will insulate and air seal in the same step. When using foam in an Attic their is no need to ventilate (This Stuff Is Good). Depending on where you live will depend on if you need an HRV or ERV.
