Frequently Asked Questions
The MG-250 is Mr Glass's aluminum impact single-hung window-wall system, built for stacked or banded elevations rather than a single isolated opening. Because it's a window-wall system, we typically install it where you want a tall run of glass assembled up to 48 by 120 inches. It's a good fit for South Florida multi-story or floor-to-ceiling layouts that still need an operable single-hung sash.
Yes. The MG-250 is dual LMI and SMI impact-rated and HVHZ-approved, so we can install it in Miami-Dade and Broward's High-Velocity Hurricane Zone. It carries Florida Product Approval FL32415.R4, and we'll confirm the current approval for your specific opening at quote.
The MG-250 is sized up to 48 inches wide by 120 inches tall as a single-hung window-wall configuration. It's rated to a design pressure of +120/120 psf for HVHZ installations. We confirm the exact size and pressure rating your opening needs during the site measure.
The MG-250 uses a laminated insulated impact makeup: 1/8" tempered glass, a 5/16" air space, 3/16" heat-strengthened glass, a .090" Trosifol PVB interlayer (Kuraray America), and a final 3/16" heat-strengthened lite. The PVB interlayer is what holds the glass together on impact. We can also spec a Low-E option such as Solarban SB70, SB70XL, or SB60 for better energy performance.
For the aluminum frame, the MG-250 comes standard with an AAMA 2604 powder-coat finish carrying a 5-year warranty, and you can upgrade to an AAMA 2605 powder coat with a 10-year warranty. Glass tint options include Clear (standard), Gray, Bronze, Solex Green, Solargray, Low-E (Solarban SB70 / SB70XL / SB60), and Privacy with a white or translucent interlayer. We'll walk you through which finish and tint fit your home at quote.
Installed pricing on the MG-250 depends on the size of the window-wall run, the glass package you choose, and the condition of the opening. Because it's a window-wall system that can reach 48 by 120 inches, larger or stacked assemblies cost more than a small unit. Armor Pro gives a free, no-obligation estimate so you get an accurate number for your project.
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 hung window opens vertically with a sash that slides up and down. On a single-hung only the bottom sash moves; on a double-hung both the top and bottom sashes tilt and slide, which makes cleaning easier from inside. They are the most common replacement window in Florida homes because they fit traditional openings and seal tightly against wind-driven rain.
