Uses For Foam Insulation
Properly insulating a home is essential to keep a home cool in the summer and warm in the winter. There is a variety of insulation products and they can all provide different levels of insulation depending on how they are used. These types of insulation are fiberglass, cellulose, rigid and foam. Though fiberglass, cellulose and rigid are less expensive, foam insulation is more commonly used. Foam is used because it takes up less space and it has greater R-values than other insulation. It is made up of a molded or extruded polystyrene or polyurethane. It can be in liquid or board form.
Liquid forms of foam insulation can be used in large or small quantities. Small quantities can be picked up at local hardware stores and used to insulate water pipes or air ducts. Whereas larger quantities are used to fill in wall cavities in existing buildings. Molded forms are large sheets of insulation that are used for insulating flat roofs or walls and ceilings. This type can also be made in smaller quantities to be used in insulating concrete blocks or hollow cavities. Extruded forms of insulation are sturdier and are also used for insulating walls and ceilings.
Though foam is most commonly used to insulate walls and ceilings, it is can also be used to insulate Flat Roof, Foam, Attics, Pipe Insulation, Materials. Foam, when sprayed in walls or floor cavities can help with soundproofing a building. Foam boards, when layed in two or more layers over a roof surface, can be used to insulate a flat roof. If moisture is a problem, foam boards can be used to form a barrier against water vapor.
When insulating a house, the attic is probably one of the most important parts of the home to insulate. Foam insulation is the most popular way to insulate the attic. Using foam as an insulator in an attic space, fills in any cracks that will prevent air from seeping into the house.
Another way to prevent heat loss from going though the attic, is to insulate the attic stairs. Fold down stairs are are often made up of a thin piece of plywood and do not seal properly. To insure proper sealing, a piece of foam weather stripping can be applied between the door and the frame. In addition the area in which the stairs fold into can be boxed in with sheets of foam insulation.

How Supertherm Ceramic Insulation Came to Be and Its Present Use
By John G White
A particular type of ceramic is produced when we chemically blend certain high performance acrylic resins. When the outer surface of two such ceramic layers is separated by the in-between third layer which behaves like an air insulator between the outer two surfaces it is called a Supertherm Ceramic insulation product.

The Many Benefits of Foam Roof Insulation
By Fay Salmons
Foam roof insulation has many benefits to your home. The insulation is created from polyurethane foam. The polyurethane foam is applied as a liquid, then dries, creating a single membrane which covers the whole roof. There aren't any seams, which is the reason for most of the leaks in ordinary roofs. This foam can be applied to the roof directly.
