Step-by-Step Installation Guide for Glass and Aluminium Fitters

What a good one includes

• Detailed pre-installation checksheets covering structural opening tolerances, substrate integrity, and tool inventory verification.
• Clear glass-handling protocols and manual lifting safety rules, including specific instructions for vacuum cup use and PPE requirements.
• A comprehensive anchoring matrix specifying the exact fastener types, spacings, and edge distances required for different substrates like masonry, steel, or timber.
• Precise instructions on using setting blocks, locating shims, and installing glazing gaskets or beads to prevent glass-to-metal contact.
• Step-by-step sealing procedures highlighting backer rod placement, wet sealing techniques, and the correct application of weather-proof silicones.
• A final quality assurance checklist focusing on sash operation, drainage weep-hole clearance, lock alignment, and hardware adjustments.

Common mistakes to avoid

• Relying on vague text descriptions rather than clear, high-contrast diagrams or photos to explain complex framing joins and sealing points.
• Failing to specify exact torque settings and fastener spacing, leading to over-tightened frames that buckle or under-secured units that sag.
• Omitting clear instructions on thermal expansion gaps, which causes aluminium frames to buckle or glass to crack during extreme weather changes.
• Ignoring the specific placement of drainage weep holes and setting blocks, resulting in trapped water that degrades laminated glass edges over time.
