Applying rigid foam insulation
Posted by Leandro,
Rigid foam insulation is easy to install with nails or glue, but its cost per unit R is much higher than that of fiber. Although the price can be generally higher than fiber insulations, rigid foam works well in places where higher R-values are necessary, particularly in small spaces. Rigid foam insulation usually is applied externally. Liquid foam is most often used in wall cavities or to seal air gaps in a home’s envelope. Rigid foam insulation material can crack and break when it’s walked upon. Once this happens you’ve limited the purpose of the product and created a thermal bridge to the cold below your slab.

Polyisocyanurate insulation is available as a liquid, aerosol sprayed foam, and as a rigid foam board. It can also be made into laminated insulation panels with a variety of facings. I have found that the foamed in place applications of polyisocyanurate insulation arecheaper than installing foam boards.
The rigid foam insulation helps you to save money by the reducing the loads on the energy used for heating and cooling of your home. If you install it, it will provide you a comfortable living and working place.
I see that foam board insulation is commonly placed between the exterior finish and the studs of exterior walls. To prevent infiltration of the air, you should place rigid insulation boards tightly together and seal the seams with tape or caulk.
I know that different parts of a building can be insulated using rigid foam board insulation. The best foam board application in curtain walls, roofs, foundations, entry and overhead garage doors, pipes and tanks; apart from being used between studs on interior and concrete walls.
My research has found that rigid foam insulation is very effective in applications with space limitations and where higher R-values are needed. The foam board insulation R-values range from R-4 to R-6.5 per inch of thickness, which is can be up to two times greater than many other insulating materials of the same thickness.
I like the fact the foam board insulation can be placed between the exterior finish or the studs of the exterior walls. This gives the contractor lots of flexibility when it comes to building a house.
I like the fact that rigid foam insulation has such a high R-value. With such a high R-value, I have the peace of mind that I will be saving on my heating and cooling costs for months to come.
