Commercial Glass & Aluminum Doors in Mississauga

There is no useful single number and a "from" price would mislead: a single aluminum entrance door in existing framing and a rebuilt two-storey glazed elevation are different orders of magnitude. What moves the price is the glazed area, the glass make-up, whether the framing is thermally broken, the door count and hardware, whether the existing framing is reused, the finish, and whether the work has to happen after hours. We measure the opening and send a firm, itemised quote at no charge.

Tempered glass is roughly four times the strength of the same thickness of ordinary annealed glass, and when it does fail it breaks into small blunt pieces rather than shards. That is a safety property, not a security one: tempered glass still comes out of the frame. Where the concern is forced entry or holding the glass in place after impact, the answer is laminated glass — two lites bonded to a plastic interlayer — or a security film applied to the glass already in the opening.

It is not one product. "Commercial grade" describes glass processed to meet the code and the duty of the opening rather than ordinary window glass: tempered or laminated where the Ontario Building Code calls for safety glazing, certified to CAN/CGSB-12.1, and sealed into an insulating unit for anything exterior. The difference from residential glass is less the glass itself than the fact that the make-up has to be specified and documented per opening.
