MG-450 Fixed Picture Window (large format)

Yes. The MG-450 is dual LMI and SMI impact-rated, meaning it qualifies for both Large Missile (low-rise) and Small Missile (high-rise) High-Velocity Hurricane Zone applications. It carries Florida Product Approval FL40676 and is rated to 85 psf positive and 120 psf negative design pressure. We'll confirm the current approval covers your exact size, configuration, and building height at quote.

The fixed picture configuration of the MG-450 reaches up to 48 inches wide by 180 inches tall, and the matching louver configuration goes up to 60 by 168 inches. That 180-inch height is what makes it Mr Glass's floor-to-ceiling picture window. We verify the maximum dimensions your specific opening and structure will support during the site measure.

The most efficient MG-450 option is the 1-inch Insulated Laminated build with Solarban SB70, which reaches a U-factor of 0.5 and SHGC of 0.246. The standard 1-inch Insulated Laminated Clear is U 0.632 / SHGC 0.591, while the basic 7/16-inch Laminated Clear is U 1.005 / SHGC 0.632. Stepping up to the insulated SB70 build roughly halves the U-factor, which matters a lot on a full-height window. We'll help you weigh energy performance against budget at quote.

Glass tint options on the MG-450 include Clear (standard), Gray, Bronze, Solargray, Solex Green, Low-E (Solarban SB70 / SB70XL / SB60), and Privacy with a white or translucent interlayer. Tinted laminated builds like Laminated Bronze (SHGC 0.508) and Solex Green (SHGC 0.502) lower solar heat gain versus clear, and adding SB70 to a tint drops it further. The aluminum frame comes standard with an AAMA 2604 powder coat (5-year warranty) and upgrades to AAMA 2605 (10-year warranty).

As a large-format, dual LMI+SMI window, the MG-450 is engineered for tall openings, and installed pricing depends on the size up to 48 by 180 inches, whether you choose the picture or louver configuration, the glass package, and the structure of the opening. An insulated SB70 build costs more than a basic laminated clear package, but it cuts the U-factor to 0.5.

Mr Glass runs a deep catalog, and we install across most of it. On the residential side that means impact windows in single-hung, horizontal-roller (sliding), fixed picture, and casement and awning styles, plus a full range of doors: entry and outswing doors, architectural pivot doors, and sliding glass doors including the multitrack pocket slider. They also build a commercial line of impact and non-impact storefronts, window walls, curtain walls, glass railings, and aluminum louvers that we handle on light-commercial projects. We help you match the right Mr Glass product to each opening and pull the matching approval for your county.

Most of the line is, but it depends on the specific product. Mr Glass's premium residential windows are dual-certified to both Large Missile Impact (LMI) and Small Missile Impact (SMI), which covers them for high-rise and coastal work anywhere in the High-Velocity Hurricane Zone of Miami-Dade and Broward. Their value-tier windows and all of their doors carry the impact certification needed for the HVHZ as well, and a couple of commercial products (the MG-275 door and MG-4500 storefront) are non-impact and are not used in the wind-borne-debris zone. We confirm the exact product, rating, and approval for your address before we quote and permit.

A fixed (picture) window does not open — it is a sealed pane that maximizes the view and daylight. With no moving parts it is the most weather-tight and energy-efficient style, and it carries the highest design pressures, which is why it is often used for large feature openings and architectural shapes.
