Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer.

This, in turn, reduces greenhouse gas emissions. Olsen Banden 1-14. Climatic conditions influence the appropriate level and type of insulation. Establish whether the insulation is predominantly needed to keep heat out or in or both. Insulation must cater for seasonal as well as daily variations in temperature see Insulation levels for your climate below. Source SEAV 2. 00. Distance to Shore. This report shows the distance to the coast. This can be tailored to meet your needs in 2 ways 1 The shoreline can be customized to meet your. The housing and residential sector demands buildings that are energy efficient, rapid to construct and of high quality. Steel and composite construction has achieved. Typical heat losses and gains without insulation in a temperate climate. Use passive design techniques in conjunction with insulation. For example, if insulation is installed but the house is not properly shaded, built up heat can be kept in by the insulation, creating an oven effect. Draught sealing is also important, as draughts can account for up to 2. Passive solar heating Passive cooling Sealing your home. Insulation can help with weatherproofing and eliminate moisture problems such as condensation some types of insulation also have soundproofing qualities. The most economical time to install insulation is during construction. For information on retrofitting insulation, see Adding insulation to existing buildings below. Most common construction materials have a low insulating value, but some require little or no additional insulation. Such materials include aerated concrete blocks, hollow expanded polystyrene blocks, straw bales and rendered extruded polystyrene sheets. Check with your local building information centre for more details. Under the Building Code of Australia BCA, the required total R values for the building fabric vary depending on climate zone see Design for climate and the building sites height above the Australian Height Datum. Ensure you comply with the BCA requirements for energy efficiency of building fabric. Choosing insulation. Insulation products come in two main categories bulk and reflective which are sometimes combined into a composite material. For the many different products available see Insulation types and their applications below. To compare the insulating ability of the products available, we need to look at their R value, which measures resistance to heat flow. The higher the R value, the higher the level of insulation. Products with the same R value have the same insulating performance if installed as specified. Check the information supplied on the product, including the R value, the price per square metre and whether it must be installed professionally or can be DIY some types of insulation require the use of masks and protective clothing. Ensure that it suits your particular application and fits within the space available. Ask if performance guarantees or test certificates are available. All insulation materials that are sold in Australia must meet Australian Standard ASNZS 4. Compare the environmental benefits of different products. Ask about recycled content and how easily the product can be recycled after use. For example, some brands of glass wool, polyester and cellulose fibre insulation contain significant amounts of recycled material. Contact the manufacturer or industry association to find out more. The appropriate degree of insulation depends on climate, building construction type, and whether auxiliary heating andor cooling is to be used see Insulation levels for your climate below. The BCA sets out minimum requirements for the R values of materials used in the construction of buildings. For reference, see BCA 2. Volume Two, Part 3. It is generally advisable to exceed these for greater comfort and energy savings. The higher the R value, the better the thermal performance. Material R values are supplied with bulk insulation and refer to the insulating value of the product alone. The higher the R value the better the thermal performance. Total R values are supplied with reflective insulation and depend on the product being installed as specified. R values can differ depending on the direction of heat flow through the product. The difference is generally marginal for bulk insulation but can be pronounced for reflective insulation. Up R values describe resistance to heat flow upwards sometimes known as winter R values. Down R values describe resistance to heat flow downwards sometimes known as summer R values. Up and down R values should be quoted when installing reflective insulation in roofs, ceilings and floors. Insulation types and their applications. Bulk insulation mainly resists the transfer of conducted and convected heat, relying on pockets of trapped air within its structure. Its thermal resistance is essentially the same regardless of the direction of heat flow through it. Bulk insulation includes materials such as glass wool, wool, cellulose fibre, polyester and polystyrene. All bulk insulation products come with one material R value for a given thickness. Source SEAV 2. 00. Bulk insulation traps air in still layers. Reflective insulation mainly resists radiant heat flow due to its high reflectivity and low emissivity ability to re radiate heat. It relies on the presence of an air layer of at least 2. The thermal resistance of reflective insulation varies with the direction of heat flow through it. Reflective insulation is usually shiny aluminium foil laminated onto paper or plastic and is available as sheets sarking, concertina type batts and multi cell batts. Together these products are known as reflective foil laminates, or RFL. Dust settling on the reflective surface greatly reduces performance. Face reflective surfaces downwards or keep them vertical. The anti glare surface of single sided foil sarking should always face upwards or outwards. Source SEAV 2. 00. Reflective insulation and heat flow. The total R values for reflective insulation are supplied as up and down values. Total values depend on where and how the reflective insulation is installed. Ensure system values provided by the manufacturer relate to your particular installation situation. Composite bulk and reflective materials are available that combine some features of both types. Examples include reflective foil faced blankets, foil backed batts and foil faced boards. The properties and uses of some common insulation materials are summarised at the end of this article. Insulation levels for your climate. The following table gives the minimum insulation levels required by the BCA for a range of locations. Some experts believe that additional insulation can further improve building performance. The table does not distinguish between directional R values for roofs and ceilings. In high humid climates where houses are naturally ventilated, high down values and lower up values are appropriate for roofs and ceilings. Minimum insulation level by climate Cool temperate Alpine. Reducing heat loss is the main priority. Example locations.
