How do glass shops ship windows and doors?

Glass is the freight category where packaging and routing matter more than almost anything else: a window that arrives 95% intact arrives 0% usable. Glass shops solve that with two habits — the freight travels upright on A-frames or in crates, and it travels direct, on one vehicle, with no terminal handling between the shop and the destination.

Here’s how that works in practice for GTA and Southern Ontario glass shops shipping to builders, glaziers, storefronts and other shops.

A-frames: the standard for racked glass

An A-frame is a steel or timber rack shaped like the letter A, and it exists because glass wants to stand up. Lites lean against the sloped faces of the frame at a few degrees off vertical, resting on a padded base rail, so the weight runs through the strong edge of the glass rather than across its fragile face.

A well-loaded A-frame follows a few consistent rules:

• Padding between every unit. Cork pads, foam separators or paper interleaf keep glass from touching glass. Two lites vibrating against each other over 40 km of road will find each other’s weak point.
• Heaviest and largest lites go on first, closest to the frame, with smaller units layered outward.
• Strapping runs over the load, padded at the contact points, so the stack cannot walk or fan out when the vehicle brakes.
• The frame itself is secured to the vehicle. An A-frame that slides is worse than no frame at all.

Racked transport suits sealed units (IGUs), single lites, mirrors and shower glass — anything that a crew will carry off by hand at the other end.

When crating is the better call

Crating makes sense when the shipment needs to survive handling the shop doesn’t control, or when the pieces are finished goods rather than raw lites. A crate is a plywood or lumber box built around the unit, with the glass blocked, padded and immobilized inside — effectively a wooden shell that lets fragile freight be treated like ordinary freight.

Glass shops typically crate:

• Finished entrance doors and door-and-frame packages, where hardware, cladding and glazing all need protection
• Oversized or heavy units that can’t safely be hand-carried off a rack
• High-value custom work — curved glass, specialty coatings, one-off architectural pieces
• Anything travelling beyond the shop’s own delivery range, where a partner carrier will handle it

The trade-off is real: crates cost time and lumber to build, and they add weight and cube. That’s why crating is a per-shipment decision, not a default — a shop delivering ten sealed units across town racks them; the same shop sending one curved storefront panel to London crates it.

Why glass moves direct

The routing decision is as important as the packaging. In a hub-and-spoke LTL network, freight is unloaded, staged and reloaded at one or more terminals between pickup and delivery. For most commodities that’s an acceptable trade for a lower rate. For glass, every touch is a fresh chance to break something that cannot be patched, and concealed damage often isn’t discovered until the unit is unwrapped at the site.

Direct delivery removes those touches: the racked or crated glass loads once at the shop and comes off once at the destination, with the same driver responsible for it the whole way. That’s the model behind same-day direct service — one vehicle, shop to site, no intermediate handling. It also solves the schedule problem, because glass is usually replacement or installation freight: a glazing crew is booked, an opening is boarded up, and the unit needs to be there the day the crew is.

Delivering to job sites and storefronts

Most glass deliveries end somewhere without a dock — a construction site, a retail plaza, an office lobby getting new entrance glass. That changes how the delivery is planned:

• Confirm access first. Site gates, laneway widths, condo loading rules and mall receiving corridors all decide what vehicle can actually get to the drop point. The same questions apply to any construction material delivered to an active site.
• Agree on who unloads. Racked lites are carried off by hand or with glass dollies, usually by the glazier’s crew meeting the truck. Crated units can be grounded by tailgate and moved with a pallet jack.
• Time the drop to the install. Glass standing loose on a site is a liability; the ideal delivery lands shortly before the crew that will install it, not days ahead.

Shops shipping doors alongside glass will recognize the same logic from cabinet and millwork shipping — finished, unforgiving surfaces, delivered to sites in install order.

Receiving: inspect before signing

Glass claims are decided at the moment of delivery. The receiver should check each crate for impact damage and, where practical, sight the glass itself — edge chips and cracked corners in particular — before signing the proof of delivery. Any exception noted on the POD at the time of delivery makes a damage claim straightforward; damage reported after the truck leaves is far harder to attribute.

The takeaway

Glass shops ship windows and doors by refusing to let the freight be handled like general freight: upright on A-frames or immobilized in crates, padded at every contact point, and routed direct so it’s touched exactly twice — once on, once off. Sonic Transport runs that kind of direct, single-vehicle delivery for shops across the GTA, Golden Horseshoe and Southern Ontario, with a real person coordinating the run and proof of delivery closing it out. If you’ve got glazing, doors or sealed units to move, tell us what’s shipping and we’ll put the right vehicle on it.
