Insulating your home will save energy and provide a healthier and more comfortable indoor environment. The heat captured from the sun or generated by your heater needs to be stopped from escaping through walls, ceilings and floors. Insulated surfaces are warmer. Condensation is less likely to form so there is less mould and mildew. In summer insulation will keep the heat out, making your home cooler. Underfloor Insulation NZ will provide a more even temperature year-round.
The initial investment of installing higher insulation than the Building Code prescribes will pay off over time because you save money in energy bills. Older homes often have little or no insulation but they can be retrofitted, making them much more comfortable and saving energy for heating. The payback period for installing ceiling insulation, for example, is about 5 years in the Auckland climate. However, the main motivation behind installing home insulation Auckland is often the added comfort and warmth, rather than financial savings.
Most insulation works by trapping air in cavities. The smaller the cavities of trapped air, the better the insulation material will work. Good examples in nature are animal shelters, such as bird’s nests, which have the ability to keep eggs and young birds at an even temperature in extreme weather conditions. The birds themselves have an added layer of insulation provided by their feathers. Humans have learned from nature’s example and clothes have been used for thousands of years to provide warmth.
We can insulate our homes by providing cavities of still air, such as in wall insulation or double-glazing. This reduces heat transfer because air is a poor conductor of heat. Another method is to use surfaces that reflect heat, such as silver foil behind radiators.
