The main heat loss in an un-insulated home is through the ceiling (42%). Walls also loose a significant amount of heat, but they are difficult to retrofit with insulation, without removing the internal lining. Floors only loose 10% of heat, but they are easy to Insulation Auckland and worth doing especially with exposed wooden floors.

It is also a good idea to have a look at your habits and preferences. If, for example, you leave curtains open at night to enjoy the view, double-glazing might be appropriate. Or if your family likes to go barefoot in the middle of winter, under-floor insulation becomes important.

Different houses need different types of insulation. Where heat is stored in the thermal mass of a building it is important to install the insulation on the correct side of the mass. A concrete floor used for heat storage needs to have the insulation underneath, not on top. Generally a mixture of heavy materials, for heat storage, and light materials, that are well insulated, is best.

The House insulation Auckland can be ineffective if it is installed poorly. How well your insulation is fitted is important, because heat can escape through small gaps or by thermal bridging. Thermal bridging occurs when a material with lower thermal resistance allows the heat to by-pass the insulation. One example is stud framing, which has a lower thermal resistance than insulation. Heat passes through the framing at a faster rate than it does through the batts in the spaces between.
