Heat Transfer and Standard Insulation

All the materials that are used in the construction of your home or business 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.

INSULADD 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 wood 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 value") the heat transfer by way of conduction only, they do nothing for the heat transfer by way of radiation.
" R values " are the ratings of a materials ability to "resist" the conduction of heat flow thru a solid. This conduction of heat transfer is between 5 % to 8 % of the total heat transfer into and out of a building
That leaves between 92 % and 95 % of the total heat transfer to be dealt with, mostly by your air conditioner and heater.

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
Summer heat gain increases interior temperatures and requires extended air-conditioning running times and winter heat loss results in the need to generate more heat and thus gives you higher heating bills.!

Your power company loves it and your heating/cooling system works trying to cope with the heat that is being radiated into or out of your home.

Standard insulation reduces the RATE of heat transfer into your home but not the AMOUNT of heat transfer. In fact standard insulation can actually work against you in the summer since your home actually stores up the heat that it has absorbed during the day and you will notice that in hot climates it may take until late evening for your home to cool down.

In the wintertime your interior walls and ceilings actually absorb a great deal of the heat that you generate with your heater. This absorbed heat them flows outward through the walls and ceilings of your home into the colder outside air.

Summary:

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.

INSULADD 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 INSULADD®?
INSULADD® 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 INSULADD® to be easily and inexpensively applied to walls and ceilings in the form of a 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.
