Product Overview

Summary: This Thermal Break Installation Safe Operating Procedure sets out a clear, safe and compliant method for installing thermal breaks in Australian residential, commercial and industrial buildings. It helps your team control construction and WHS risks while achieving consistent thermal performance outcomes that align with NCC energy efficiency requirements.

Thermal breaks play a critical role in preventing thermal bridging through steel and aluminium framing, roof systems and cladding assemblies, but their installation often occurs in tight, elevated and weather-exposed work areas. This SOP provides a structured, step-by-step process for installing thermal breaks safely and correctly, from pre-start planning and material handling through to final inspection and documentation. It addresses the real-world challenges faced on Australian construction sites, including working at height, sharp edges, hot surfaces, and coordination with other trades.

By implementing this procedure, businesses can significantly reduce the risk of falls, lacerations, heat stress and manual handling injuries while ensuring thermal breaks are installed in accordance with manufacturer instructions and NCC performance requirements. The SOP supports WHS due diligence by clearly documenting responsibilities, required PPE, hazard controls and verification checks. It also helps builders and contractors minimise rework, avoid costly non‑compliance with energy efficiency provisions, and deliver consistent, high‑quality building envelope performance across projects and teams.

Key Benefits

• Ensure safe installation of thermal breaks around roofs, walls and structural steel, reducing the risk of falls, cuts and heat-related incidents.
• Improve compliance with NCC energy efficiency provisions and relevant Australian Standards for building envelope performance.
• Standardise installation methods across crews and sites, reducing defects, rework and warranty claims.
• Reduce project delays by providing clear sequencing of works and coordination requirements with other trades.
• Demonstrate WHS due diligence with a documented, repeatable procedure that supports training, inductions and audits.

Hazards Addressed

• Falls from height when installing thermal breaks on roofs, elevated platforms or external facades
• Slips, trips and falls on partially completed roof decks, battens and framing
• Lacerations and puncture wounds from sharp metal edges, fasteners, foil facings and cutting tools
• Heat stress and dehydration when installing on exposed roofs in hot Australian conditions
• Musculoskeletal injuries from repetitive movements, awkward postures and manual handling of rolls, sheets and boards
• Exposure to dust, fibres or adhesives when cutting and fixing thermal break materials
• Electrical contact risks near overhead or concealed services during installation
• Fire risk from hot works (e.g. cutting, grinding) near combustible insulation or packaging
