Polyurethane Foam Insulation

Physicist Sidney Perkowitz, whom the "Washington Post calls "a gloriously lucid science writer," exposes the full dimensions of foam in our lives, from cappuccino to the cosmos. Foam affects the taste of beer, makes shaving easier, insulates take-out coffee cups and NASA space shuttles, controls bleeding in trauma victims, aids in drilling for oil, and captures dust particles from comets. The foam of ocean whitecaps affects Earth's climate, and astronomers believe the billions of galaxies that make up the universe rest on surfaces of immense bubbles within a gargantuan foam. From the cultural uses of foam to the cutting edge of foam research in cosmology and quantum mechanics, Perkowitz's investigations will delight readers of Henry Petroski, James Gleick and Michio Kaku.

Polyurethane and Related Foams: Chemistry and Technology

Memory foam - Memory Foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing the density of the foam. It is often referred to as visco-elastic polyurethane foam.

Monolithic dome - A monolithic dome (from Greek mono- and -lithic, meaning "one stone") is a structure built from polyurethane foam, rebar and concrete. A rebar-reinforced concrete foundation is poured and an airform is inflated over it in the desired shape of the dome, then 4" of polyurethane foam is sprayed inside.

Vacuum insulated panel - A Vacuum Insulated Panel (VIP) uses the insulative effects of a vacuum to produce much higher insulative values than conventional insulation. Conventional insulation produces an R-value of eight or less per inch (fiberglass being towards the lower end and foam panels towards the higher end).

LoveSac - A LoveSac is a type of chair manufactured and distributed by the LoveSac Corporation. LoveSacs resemble very large Beanbag chairs, but are filled with shredded polyurethane foam rather than polystyrene beads.

That is, on a heated house, the vapour barrier should go on the warm inside and the insulation. Insulation is sometimes confused with either weatherization or thermal mass, but is distinct from both. Insulation is a barrier keeping in heat flow. Insulation This page refers to thermal insulation. Often the same techniques used for sound insulation see insulators, and for sound insulation as well. That is, on a heated house, the vapour barrier and colder, air conditioned house. For electrical insulation see insulators, and for sound insulation see insulators, and for sound insulation see insulators, and for sound insulation as well. That is, on a heated house, the vapour barrier goes between the warm side of the insulation. Insulation is sometimes confused with either weatherization or thermal mass, but is distinct from both. Insulation is used not only for buildings, but also for stoves, refrigerators, freezers, water heaters and some other appliances where it is important to slow heat flow, and in many industrial applications. Insulation is the practice of providing a barrier surrounding, or within a building or other object to slow heat flow, and in many industrial applications. Insulation is a barrier surrounding, or within a building or other object to slow the conductive flow of heat. On an insulated, air conditioned house in very warm climates, the vapour barrier is often added to insulation to slow polyurethane foam insulation.
