Insulation is a key factor of a building that acts like a barrier for reducing the heat flow. It is also essential for keeping the rooms warmer during winter and cooler in summer. A properly insulated home provides comfort to the occupants all the year round and also cuts down on energy bills by almost to half. This means you can reduce the greenhouse gas emissions significantly.
The type of insulation depend on the climatic conditions of the region you live in. Before you opt to buy a specific insulation material it’s crucial to consult with a certified company that provides house energy rating assessments. This is important especially if your building is developing moisture. In such cases the energy bills go too high and also cause to harm to the environment.
What could be the best time to install insulation?
Insulation must be installed when you’re heading for a construction project. The type of construction also determines whether you need a retrofitting insulation or an adding insulation. Before you purchase a material, make sure that it meets the building codes. This is because, most of them have a low insulating value that may fall in quality as soon the temperature changes. This is a common scene in aerated concrete blocks, straw bales, hollow expanded polystyrene blocks and rendered extruded polystyrene sheets.
In Australia, there are different climate zones. Due to this reason, the required R-values under the Building Code of Australia (BCA) varies. As per the Australian Height Datum, the height of the building site may also differ from others.
Types of insulation
There are two main categories of insulation, bulk and reflective. These are sometimes combined into a composite material. It is the R-value that determines the ability of insulation of a specific product. This further measures the resistance to heat flow. The higher the R-value, the bigger the insulation a building has. However, the same R-values may not prove to be as much beneficial if installed in a different climatic zone.
Generally the information is given on the product and it includes the R-value, price per square metre and whether it can be installed through a professional or DIY.
Keep in mind that no matter what materials you choose for insulation, they must meet Australian Standard AS/NZS 4859, even if they are imported. Thus, the best option that remains is to hire an assessment team in Australia to get professional recommendations.
