Insulation
 
What is the best type of insulation to use? Does it depend where you live or what kind of house you're building?

To answer your first question; everybody has their own opinion. Exterior wall I've been using a product called NU-WOOL. Check their web site. Also Old fashion fiberglass batt, is still popular.

To answer your second question; YES...

You must be referring to ICYLENE spray foam insulation.
The prices are dependant on your area and the demand, as well as the companies who are available to do it...

Plan on spending at least double ...and up to three times the amount of fiberglass insulation.


Example: 20'x20' Sunroom addition, our company is currently constructing...(the forms go in on Monday 12/04)

These are the written estimates for insulating the ceiling, walls, and floor.

Fiberglass Insulation: $1275.00 (Our company quote)

Other Company #1 Icylene: $2530.00

Other Company #2 Icylene: $3720.00


Hope that helps.
Any company can give you a written quote if you supply the plans to them ...(Tho, they prefere to actually 'see' the job for accuracy)

Just so you know: If you insulate with Icylene in your rafter areas, you don't need to provide ventilation (No soffit venting, no rafter venting, no ridge venting = these do add up to some savings)
It is considered superior for 'air tight' insulating(walls) and 'moisture tight' insulating (Crawl spaces).

Usually double or a little more. It is without doubt the best insulation as far as effectiveness, but it's hard to justify the cost if you live in a moderate climate area. Also be sure to think of everything you need to run in the walls, now or future. Fishing wires is almost impossible.

How much area do you need to do or is it the whole house?

If you are building the house consider building masonry walls from AAC blocks (autoclaved airated concrete). It's concrete mixed with an ingredient that makes tiny airbubbles which accounts for the higher R value (1.25 per inch of wall thickness).

The stuff can be cut with woodworking tools and weighs only half of regular concrete blocks. You can lay up the wall yourself from small blocks or have a construction company drop in place large iron reinforced panels. panels are available to make walls, floors and roofs. The entire shell can be constructed from this and put up in 2 days.

It is a better wall tha a woodframed one. Depending on where you are you may not need additional insulation.

Manufacturers of the blocks/panels: Aercon, ACCOA, MHE, Truestone.

foam
 
Consider an inch of foam and the rest fiberglass.
