This type of insulation is considered highly effective, lightweight, flexible and resilient insulation. The materials used in this type of insulation can be made from includes Glasswool (fibreglass), Rockwool, Natural wool and Polyester. This insulation is highly used for its efficiency and quality. A professional installation is recommended.
Boards insulation
This type of insulation is used mainly in cathedral ceilings. Using Extruded polystyrene or Foil-faced expanded polystyrene. A professional installation is recommended.
Reflective insulation
Reflective insulation is made of thin sheets of highly reflective aluminum foil laminate, which reflects heat from its polished surfaces while absorbing and emitting only a small amount. For maximum effectiveness it must work in conjunction with a still air layer. An R value supplied by reflective foil insulation is equivalent to the same R value provided by bulk insulation. Reflective foil R values are influenced by the characteristics of adjacent air spaces, such as their orientation, thickness and temperature differences.
Adequate performance can be achieved by combining reflective insulation with bulk insulation and/or using specialist foil products, provided they are carefully installed. Any gaps or tears will significantly reduce performance, as will dust buildup on surfaces.
Loose-fill insulation
This type of insulation consists of shredded or granulated material supplied in a loose form, and is Better installed by the a certified installer/supplier. It must be correctly installed at even depth to provide adequate insulation cover. Barriers should be installed to prevent insulation falling down through exhaust fans, wall cavities, ceiling vents and light fittings. This insulation is highly used for its efficiency and environment value. A professional installation is recommended.
What is Overall R value?
The Australian Government requires all installation including the products to satisfy an overall R Value. Basically, the overall R value is the total resistance of a building element. It takes into account resistance provided by construction materials used in a wall or ceiling, internal air spaces, thermal bridging, insulation materials and air films adjacent to solid materials. Each of these components has its own inherent R value, the sum of which provides the overall R value.
Insulation Select installers are committed to provide products that satisfy the Australian government R-value standards and requirements. This gives you the peace of mind that you have quality home insulation and are eligible for the government Energy Efficient $1,600 rebate. Book here.

Added R value
The added R value or added thermal resistance is the value of the insulating material alone. This is the term most used when buying insulation. The manufacturer should provide the R value of bulk insulation. Some products will trap air or gas more effectively, and so will have a higher R value for a specified thickness. For example, 45 mm thick extruded polystyrene and 80 mm thick glasswool both have an R value of approximately 1.5. Reflective insulation must work in conjunction with enclosed air spaces between surfaces, and cannot be said to have an R value by itself. To compare the performance of bulk and reflective insulation, the resistance of any existing air space(s) must be calculated. Reputable manufacturers can supply this information. Note that the effectiveness of reflective insulation installed on horizontal or sloping surfaces will eventually be reduced due to dust build-up, which reduces reflectivity.
