Insulation plays a vital role in regulating indoor temperature, reducing energy consumption, and improving acoustic comfort. Common materials include Earthwool, a soft, sustainable form of glasswool known for its non-combustibility and low irritant properties. Traditional glasswool batts, such as Pink Batts, are widely used for their thermal efficiency and fire resistance. For higher-density applications, Rockwool, offers excellent fire performance and sound insulation, especially in commercial and multi-residential buildings. Wraps and sarking are reflective insulation layers installed behind external cladding or roofing to reduce radiant heat and protect against moisture ingress. All these products are designed to meet or exceed Australian standards for thermal resistance (R-value), fire safety, and environmental impact, ensuring safe and efficient building envelopes across diverse climates and construction types.
