Foam insulation
Thank you for your time to answer my question!
I have 700 square feet to insulate — is an attachment room to a frame house, built very poorly, and is very cold and hot. I’m doing now fixing up.
Question: I have walls 3 inches deep, and celling is 12 inches deep. I was going to spray foam with closed cell.
Can I maybe (to reduce cost) install fiber insulation? Or styrofoam, 1-2 inches, then spray with closed-cell over that?
Or is it a good idea to spray one inch of closed-cell and do the rest with open-cell over closed-cell?
Will there be big difference in closed-cell vs open-cell if I spray using only one type?
And last question: What is the best way to heat this room? Efficient by using electric heat?
I can’t use regular baseboard heaters. I need some other idea if you know.
What is the best way to insulate the room? Can I use a combination of spray foam (closed-cell) with some other material to reduce the cost and still be efficient?
See pictures — how it looks now.

Enes,
It seems to me that you have some very basic questions.
Are you the homeowner or the builder? If you are the homeowner, do you have a contractor -- or are you doing the work yourself?
Assuming that you are the homeowner, and you have a contractor, the first step is to talk with your chosen insulation contractor. What does your contractor recommend?
For basic information on all of the various types of insulation available, I suggest that you start by reading the articles on these topics in the GBA Encyclopedia:
