Product Overview

Summary: This Insulation Air Sealing Solutions SOP provides a clear, step‑by‑step method for safely installing and maintaining air sealing systems in Australian residential and commercial buildings. It focuses on controlling WHS risks such as working at heights, confined roof spaces, heat stress, dust and fibres, while helping your business deliver energy-efficient, code-compliant outcomes.

Air sealing is a critical component of modern insulation systems, directly impacting building performance, occupant comfort and energy costs. However, installing air sealing solutions often involves accessing roof cavities, subfloors, wall voids and other high-risk areas where workers are exposed to falls, heat, electrical services, dust and restricted movement. This Safe Operating Procedure sets out a structured, safety-first approach to planning, preparing and carrying out insulation air sealing tasks in line with Australian WHS requirements.

The document guides your team through pre-start assessments, hazard identification, safe work methods and quality checks specific to air sealing activities—such as sealing penetrations, junctions and gaps around services, ducts and building elements. It helps you manage key risks like working at heights, exposure to insulation fibres, contact with live electricals and manual handling of bulky materials, while also embedding best practice installation techniques that reduce air leakage and thermal bridging. By implementing this SOP, businesses can demonstrate due diligence, improve installation consistency across crews, reduce rework and call-backs, and support compliance with NCC energy efficiency provisions and relevant Australian Standards.

Key Benefits

• Ensure safe planning and execution of insulation air sealing works in roof spaces, wall cavities and subfloors.
• Reduce the likelihood of falls, heat stress, electrical contact and dust exposure during installation activities.
• Standardise installation techniques to improve air tightness performance and reduce energy loss in buildings.
• Demonstrate compliance with Australian WHS legislation, NCC energy efficiency requirements and relevant standards.
• Streamline training and onboarding by providing clear, repeatable instructions for new and existing workers.
