Why does putting foam in a gap in a cavity wall keep a house warmer?

Foam will block heat from escaping.


Why are foam filled cavity walls are better than air filled cavity walls in reducing heat loss?

Foam is a good insulator- this means that it traps still air and prevents heat travelling and being lost. Heat is lost more easily through the air in air-filled cavity walls as the air is not kept still.


Why Does filling a cavity with foam reduce heat loss even further?

Because foam has many little air pockets, which reduce heat loss. Also, air is an insulator which means it is a poor conductor. Hope that helped!

Why do you fill cavity walls with insulation foam?

Insulating foam is just one thing that can be used. Insulating the wall cavity stops heat exchange with the exterior which is a problem during extreme climate conditions like winter and summer. Insulation works by stopping air movement through the cavity. The real trick of insulation is that it isn't the insulation material itself that stops the heat exchange, it is the air trapped in it that does. Air is a poor conducter of heat energy provided that the air is stagnant (not moving around). When applied, the foam bubbles up as it expands, trapping air in the bubbles as it hardens making it an excellent heat insulator by virtue of the air trapped in it.

Expendable pattern is usen in which type of casting?

Expendable pattern is used in Investment Casting process. It consists of Polystyrene foam and the process known as Lost Foam Process. An intricate design is made of polystyrene foam with help of hand tools or injection molding type process and allowed to enclosed by sand as in other sand molding, then directly molten metal is poured in to the mold without removal of pattern instantly the pattern burns and the molten metal fills the cavity. By this process an intricate shape object can be cast. As, the foam is not been reclaimed it is known as Lost Foam Process.
