Insulation Fundamentals

As energy prices soar worldwide, premiums are placed on energy efficient design and systems that promote energy related cost savings. Your home, work space, factory or warehouse will be more comfortable and energy efficient with the right insulation.

Insulation helps reduce the costs of cooling your home. Specialists have estimated that 35-45% of precious energy used for cooling in a tropical climate is wasted due to buildings not using effective or efficient thermal insulation practices.

It does this by eliminating heat flow that occurs through a combination of convection and conduction. A properly insulated home reduces heat flow from outside your home into your living space, using less energy in the summer for cooling. That directly translates into money in your pocket.

How heat transfers into your living space

External heat builds up on a roof or wall structure and is radiated into the space inside. Most building materials are developed to keep the rain and wind out but are not thermally efficient (i.e. they allow the transfer of heat) while at the same time allow cool air from within the building to escape.

The result of this is a building that is uncomfortable to live and work in. Air conditioners are typically required to worker harder to maintain a set temperature, thus consuming more energy and costing more money.

How insulation works

Insulation works as a barrier separating hot and cold surfaces, in effect not allowing them to come into contact and affect each other.

Correct insulation minimizes heat transfer

Adding insulation to a building structure works to reduce unwanted heat flow permeating into the building from the outside. It also works to maintain the circulation of cool air within the building by not allowing it to escape. A direct consequence of this is reduced energy consumption as the air-conditioners operate below capacity to maintain the desired conditions within the living space. . The air-conditioners are creating the same effect but doing less work!!! Insulating your building can reduce your air-conditioning costs by more than 40%!!! In addition to this, your air-conditioner lasts longer with less maintenance required because the unit is not constantly working to counter the effect of the heat leaking into and the cold air leaking out of the building. Incidentally, in a cold climate a good insulation barrier works reverse by keeping heated air inside a building.

Measuring the performance of different types of insulation

Look for the "R-value." "R" means resistance to heat flow. The higher the R-value, the greater the insulation factor. The R-value (certified) should be disclosed for all insulation products. If the R-value is not disclosed, don't buy the insulation. There are two internationally accepted scales for R-values.

a) Metric (m2k/w)

b) Imperial (BTU/ft2hoF)

Simply multiply metric value (A) by 5.678 to obtain an imperial value (B) (e.g. R1.8 x 5.678 = R 10.22). Simply divide imperial value (B) by 5.678 to obtain a metric value (A) (e.g. R10.22 / 5.678 = R1.8). Now you can accurately compare any type of insulation with another.

Effectiveness of Insulation

The R-value of a product is not always an indication of actual performance of that product in your ceiling or wall structure. The reason for this is the gaps that occur between batt and roll insulation when they are actually installed. The gaps will allow for heat gain and cool loss, reducing the efficiency of the insulation and compromising its performance. An analogy is a glass filled with water. If the glass is sound the water remains in the glass, whereas if the glass is cracked the water trickles out of the glass, reducing the effectiveness of the glass as a vessel to hold water.

?You will lose 50% of the R- Value. You are only getting half the insulation with batts?
In choosing an insulation product, choose one with NO GAPS!!!
