Foam insulation? Good/Bad?

Hello,

Has anybody used foam insulation in their home remodel? It's a bit more expensive but I am wondering how much of a difference it will make. I am remodeling a home in the pacific northwest. Most months require heating.

Does anybody have experience with the Corbond or InsulStar brands?

What is the best material to use for heat and cold insulation in your home? The fact is that the material that the insulation is made from is not what provides the heat and cold barrier. It is the air that is trapped in the insulation that provides the thermal barrier that keeps you warmer in the winter and cooler in the summer. Each type of insulation, whether it is a foam product, fiberglass batts or shredded paper provides different sizes and numbers of air pockets within them. That is why crushing insulation or pushing insulation into a crevice is counterproductive, it removes the air pockets, which is what provides the thermal barrier.
Now you can paint and insulate at the same time!
A relatively new product to enter the market provides air pockets within paint. The principle of the product is based on a complex blend of microscopic hollow ceramic spheres. Each ceramic sphere has a vacuum inside it, similar to mini thermos bottles. By mixing the ceramic spheres into paint it creates a product that provides enhanced insulation and saves you energy and money.


The paint, with its ceramic additive has proven to increase the "R" insulation level of walls and ceilings. While use of the product on interior walls is extremely beneficial, its use on exterior walls is even more dramatically effective since it blocks the extreme heat of the sun.

The ceramic materials have unique energy savings properties that reflect heat while dissipating it. The hollow ceramic microspheres reflective quality affects the warming phenomenon called "Mean Radiant Temperature," where heat waves from a source such as direct sunlight cause a person to feel warmer even though the actual air temperature is no different between a shady and sunny location. It is the molecular friction within the skin caused by the sun's radiant energy waves, which makes the mind think that the body is warmer. The ceramic microspheres in the paint refract, reflect, and dissipate heat.

I'm sure that was not the answer you were looking for. the truth is, it will take a very long time to realize any energy savings. In other words, it will take a long time to recoup the extra bucks you spent on foam as opposed to fiberglass for example. A long time, especially if you successfully invested the amount of money you did not spend on the foam. If you are borrowing the money, well, do the math.

Sealselection 500 is the best product. It has a extremely high R value and will make you house like a giant igloo. Requires know how on hvac and return air systems. Costs more than insulation but saves of hvac tonnage and huge on electric bills - like half of normal.
