Product Overview

Summary: This Double-Glazing Installation Techniques SOP sets out a clear, step-by-step method for installing double-glazed windows safely, accurately and in line with Australian WHS and building requirements. It helps glazing and construction businesses control high‑risk tasks such as glass handling, work at heights and use of power tools, while delivering consistent, high‑quality installations for clients.

Double-glazing installation involves a combination of high-risk construction activities: handling large glass units, working at height, operating cutting and drilling tools, and interfacing with building envelopes that must remain weather-tight and secure. Without a structured procedure, even experienced installers can introduce safety risks, rework, air and water leaks, and non-compliance with NCC and WHS obligations. This SOP provides a disciplined, repeatable method for planning, preparing and executing double-glazing installations across new builds, retrofits and replacements in residential and commercial settings.

The document walks your team through each stage of the job: pre-start checks, site access and traffic control, verification of measurements and frame condition, safe manual handling and lifting of glass units, correct fixing and sealing techniques, and final inspection and sign‑off. It embeds WHS risk controls directly into the workflow, ensuring hazards such as falling objects, glass breakage, musculoskeletal strain and exposure to silica dust from cutting operations are systematically managed. By implementing this SOP, businesses can demonstrate due diligence, reduce callbacks and warranty claims, and protect both workers and clients while meeting Australian standards for glazing performance and safety.

Key Benefits

• Ensure safe handling, lifting and installation of double-glazed units to minimise injuries and breakages.
