add_book4Insulation (Netting and Biffing)

It is difficult to overemphasize the need to properly insulate a house.  Builders generally try to cut corners by providing only minimal amounts of insulation, but that is a disservice to the customer, because the house owner will pay a lot more over time in energy costs than what the extra insulation costs.  It would seem to me that the least a builder could do is inform a potential customer of the extra cost involved, so that the person could make an informed judgment.  Though I don’t consider myself to be a “green freak,” I do think of myself as a responsible human being who appreciates the fragility of the environment.  Pragmatically, most Americans will have less and less as they live out their lives, so costs are important–especially to those of us with limited means–as we sail into our golden ages.

There is, I am convinced, though once again arguable, a method of insulating a house which is better than using only insulation batts (see Images 38 and 39).  The jargon used for this process by those who insulate houses is called “netting and biffing.”  This is accomplished by first securing a thin net material over the exposed interior wall studs and then by blowing in the insulation into each section of the wall.  Workers who do this simply make a hole in the netting and pump the area full of insulation, while another worker in the truck moistens the material being pumped into the walls of the house.  Avoid using any insulation which has formaldenhyde as a chemical in it, whether batt or blown-in insulation.
