Thermal Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. A well-insulated and well-designed home provides year-round comfort, cutting cooling and heating bills, and reducing greenhouse gas emissions.

Acoustic Insulation provides sound isolation from adjoining spaces and prevents sound leakage from your space into neighbouring spaces. This will mean – more privacy, better sound quality within the space and reduced noise ingress from outside.

Insulation products come in 2 main categories — bulk and reflective — which are sometimes combined into a composite material.
All insulation materials sold in Australia must meet Australian Standard AS/NZS 4859 Materials for the thermal insulation of buildings.

Commonly used insulation materials are

• glass wool, batts and rolls (often made from recycled materials)
• wool, batts and loose fill
• cellulose fibre loose fill (often made from recycled paper fibres)
• polyester, batts and rolls (often made from recycled materials)
• polystyrene, expanded (EPS) or extruded (XPS), as rigid boards
• polyisocyanurate (PIR) as rigid boards

How well an insulation product resists heat flow is known as its R value. The higher the R value, the higher the level of insulation. The National Construction Code (Nathers) and BASIX (in New South Wales) set out minimum requirements for the R values of materials used in the construction of buildings. It is generally advisable to exceed these for greater comfort and energy savings.
