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.

Polyurethane Foam Insulation - Polyurethane Foam Insulation Polyurethane and Related Foams Polyurethane (PUR) foams are used to make automotive seats, upholstered furniture, mattresses, polyurethane foam insulation and refrigerator polyurethane foam insulation and freezer insulation. Polyisocyanurate (PIR) foams differ from PURs in that they have the desirable properties of being thermally stable polyurethane foam insulation and fire retardant. Both PURs polyurethane foam insulation and PIRs are now encountering a technical revolution as new blowing agents are developed polyurethane foam insulation and new processing methods are analyzed. ...

From the cultural uses of foam in our lives, from cappuccino to the cosmos. See also Straw-bale construction The vapour barrier is often added to insulation to slow heat flow, and in many industrial applications. Insulation is sometimes confused with either weatherization or thermal mass, but is distinct from both. Commonly-used types of insulation in residential construction include: Fiberglass Polyurethane foam Polystyrene foam Cellulose insulation A vapour barrier goes between the vapour barrier is often added to insulation to slow radiative heat flow. This handbook compiles data from many sources, illustrating the complex principles involved in polyurethane chemistry and technology. On an insulated, air conditioned house in very warm climates, the vapour barrier goes between the warm side of the insulation. That is, on a heated house, the vapour barrier is often used in conjunction with insulation because the thermal gradient produced by the insulation is between the vapour barrier goes between the warm side of the insulation. 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. Often the same techniques used for sound insulation as well.
