Insulation Options. Climate Zone 7 can provide the advice and the expertise for your insulation requirements. Climate Zone 7 provides the following insulation solutions with a number of options to suit the requirements of the project:


A Smart Choice. Climate Zone 7 delivers insulation solutions for ceilings, walls and under-floor areas across Melbourne and Melbourne Metropolitan Areas. We also service outer Melbourne regional areas.

Choosing the right insulation material is important to meet building code requirements. Importantly however, when temperatures in Melbourne are more extreme and energy costs are high, the right insulation will provide a more comfortable working and living environment with lower energy costs.

Thermal insulation provides a layer of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body.

The insulating capability of a material is measured as the inverse of thermal conductivity. Low thermal conductivity is equivalent to high insulating capability. In thermal engineering, other important properties of insulating materials are product density and specific heat capacity. Climate Zone 7 can assist in selecting the most appropriate solution.

Insulation Types
Bulk insulation

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.

Reflective insulation

Reflective insulation mainly resists radiant heat flow due to its high reflectivity. It relies on the presence of an air layer of at least 25mm next to the shiny surface. The thermal resistance of reflective insulation varies with the direction of heat flow through it.

Reflective insulation is usually 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.
