🚪💥 Broken Commercial Door Window Montreal – Full Aluminum Doors (1960-1990 & Newer Models) 🏢🔧
Commercial aluminum entrance doors are common on stores, offices, schools, restaurants, apartment buildings & industrial properties.
Many older commercial aluminum doors built between 1960–1990 usually have a single glass panel/window 🪟
Newer codes and regulations changed requirements — many commercial doors today use tempered glass, insulated (thermo) glass, or safety glass ⚠️
❓Why Do Commercial Door Windows Break?
Most people think glass only breaks during a break-in. Not always.
⚠️ Common causes:
🔨 Forced entry / vandalism — hammer strikes, impacts, attempted break-ins.
🚚 Accidental impact — carts, ladders, tools, equipment, deliveries, construction work.
🔐 Electric strike installation — while installing a new strike, hardware or tools may accidentally touch the glass. Tempered / thermo glass can suddenly explode 💥
🪛 Wrong screws installed before — drywall screws with cone tips can touch the hidden glass behind the frame. Later, tightening a screw can crack or explode the window.
🚪 Hinge replacement — installing Select Hinges / Piano Hinges / Adjustable Hinges. A screw that is too long may touch the glass and break it.
⚙️ New commercial lock installation — some lock mechanisms require drilling top & bottom mounting holes. Press too hard while drilling and the drill can go straight into the window 😬
From our experience as locksmiths, yes… it can happen during repair or installation work too. 🔧
