When does heat transfer stop?

Answer 1

Heat Transfer and Standard Insulation

All the materials that are used in the construction of your home, business and buildings absorb and transfer heat. 80% - 95% of this heat is transferred! Heat ALWAYS flows from the warmer side to the cooler side by one or more of the following ways.

Standard insulation works by slowing down the RATE of transfer of the heat that has been absorbed by the walls, and roof or your home.

Thermilate greatly reduces the AMOUNT of heat the walls and ceilings (and roofs too!) absorb, heat that you are either trying to keep in or out!

Conduction - Conduction is the transfer of heat through a solid object. When one part of an object is heated, the molecules within it begin to move faster and more vigorously, when these molecules hit other molecules within the object they cause heat to be transferred through the entire object.

Convection - Convection is the transfer of heat by the movement of a fluid (water, air, etc.) Inside of a wall cavity, air removes heat from a warm interior wall, then circulates to the colder exterior wall where it loses the heat.

Radiation - Any object will radiate heat to cooler objects around it by giving off "heat waves". This is a direct transfer of heat from one object to another, without heating the air in between. This is the same process in which the Earth receives heat from the Sun or a heater stove supplies heat to its surroundings.

How do we stop this transfer?

We have commonly used (mass) insulation such as Fiberglass, Cellulose, Styrofoam, etc. to slow down and resist R or U value1, the heat transfer by way of conduction only; they do nothing for the heat transfer by way of radiation.

Mass insulation products work by trying to " trap " the heat in air pockets contained between the fibers in the product. Air is a good insulator against conduction but cannot stop radiant heat! Once the insulation becomes saturated with all the heat it can absorb the heat is then transferred on through the wall or ceiling.

In the wintertime your interior walls and ceilings actually absorb a great deal of the heat that you generate with your heating system. This absorbed heat then flows outward through the walls and ceilings of your home into the colder outside air. This results in an Increased heat requirement and thus gives you higher heating bills.

In Summer the heat gain increases interior temperatures and requires extended air-conditioning running times thus gives you higher cooling bills!

Summary:

Standard insulation works by slowing down the RATE of transfer of the heat that has been absorbed by the walls, and roof of your home.

Thermilate greatly reduces the AMOUNT of heat the walls and ceilings (and roofs too!) absorb, heat that you are either trying to keep in or out!

Why THERMILATE?

THERMILATE reduces the insulative demands placed on conventional insulation which may have been poorly installed or have deteriorated due to dampness or age. The ability of THERMILATE to be easily and inexpensively applied to walls and ceilings in the form of a insulating paint additive which creates a thermal barrier is a superior method for the homeowner to utilize in order to maximize the energy efficiency of a home or building. Upgrading the inner - wall or ceiling insulation in older or poorly insulated buildings can be an expensive, sometimes impossible task and one which may be too expensive to consider.
