MG-350 Single Hung Window

Yes. The MG-350 SH is LMI 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 FL418887.R2 and is rated to 65 psf positive and 80 psf negative design pressure. We'll verify the current approval covers your exact size and opening at quote.

The MG-350 SH is sized up to 53.625 inches wide by 76 inches tall in its impact-resistant configuration, rated to +65/80 psf design pressure. That covers most standard residential single-hung openings in a replacement project. We confirm the maximum size your specific opening will support during the site measure.

The MG-350 SH uses a 5/16-inch laminated makeup with a 0.090-inch Trosifol PVB interlayer by Kuraray for its impact protection. The most efficient packages add Solarban SB70 Low-E: the Laminated Gray with SB70 reaches U 1.057 / SHGC 0.272, and the Gray Translucent SB70 build drops SHGC to 0.252 with added privacy. The basic 5/16-inch Laminado Clear is U 1.068 / SHGC 0.626, so the SB70 builds cut heat gain considerably.

Glass tints on the MG-350 SH 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 Solargray (SHGC 0.494) and Bronze (SHGC 0.506) reduce solar heat gain versus clear. The aluminum frame comes standard with an AAMA 2604 powder coat (5-year warranty) and upgrades to AAMA 2605 with a 10-year warranty.

The MG-350 SH is the value-tier choice, so it's geared toward budget-conscious replacements, but installed pricing still depends on the size up to about 53 by 76 inches, the glass package you select, and the condition of the existing opening. An SB70 Low-E build costs more than a basic laminated clear package. Armor Pro gives a free estimate so you get an accurate installed price for your home.

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.
