why do we need insulation in our homes

house with insulation can reduce heating and air conditioning costs by up to 40. This translates to massive savings on energy bills and a lot less pollution due to less energy usage. The money saved from reduced energy consumption greatly outweighs the cost of the insulation which, in the end, essentially pays for itself. The effectiveness of insulation as a heat barrier is deteremined by many factors, however it is largely and most importantly determined by its thermal conductivity. This value denotes the resistance the material has against heat transfer across the material. This is the common value that industry uses as a comparison between products, however it is not the only factor on which a decision should be made (other important factors affecting one s decision should be cost, safety and feasibility of the product). Insulation is only one part of an energy-efficient home.

Other areas of heat loss/gain are windows/doors, walls, air-gaps and even the floor. While the ceiling contributes the most heat lost and gained in a home, the other areas should also be considered. Having windows tinted and covering with thick curtains can also help, as can opening and closing doors and windows at appropriate times of the day. Other underestimate heat generating devices are lamps, especially halogen lamps, which create lots of heat. Now a day the cost of green substitutes such as LED lights is low. These apart from generating nearly no heat, they consume a fraction of the electricity of a traditional bulb. (We also carry a range of both domestic, commercial and steet LED lighting products) Ceiling insulation is particularly important as the highest proportion of heat transfer occurs through the roof and ceiling, but there are other areas of your home that can be insulated as well.

To maximise the efficiency of your insulation, to reduce heated or cooled air leaking from cracks and gaps around windows and doors, this can reduce heat loss by up to 25%В from your home in winter. If your roof or ceiling isn't insulated, you could lose up to 40% of your heating and cooling energy via the roof. Verandah roofs should be insulated in hot climates to reduce heat from the sun, as this not only affects the space below, but also the temperature inside the house. Covered verandahs and garages might benefit from insulation if you spend a lot of time in these areas, especially if you're heating or cooling them. Wall insulation can save up to 25% of. Consider added wall insulation as an essential in all climates. Exceptions to this would be homes constructed from straw bale (and to a lesser extent autoclaved aerated concreteвAAC).

If wall insulation is not already fitted, or if your existing insulation is insufficient, it can be retrofitted. Speak to your installer about the correct product for your particular home and location. Appropriate floor insulation can save up to 20% of heating and cooling energy. Carpets are one option to insulate a floor. In hot climates floor insulation may interfere with the natural cooling from the ground beneath the house. Seek advice about the best option for your home and circumstance. Water pipes inside walls can be insulated when. To avoid further heat being lost from a storage hot water system, insulating externally exposed pipes leading from the water heater to the house as well as the water tank itself is recommended.
