MG-350 Windows Series

Budget-friendly

Best for: Homeowners who want impact windows on a tighter budget for everyday bedroom and living-room openings in normal wind-load areas.

The MG-350 series shares one slim 2-3/16 in. aluminum frame across a single-hung (MG-350 SH), a horizontal slider (MG-350 HR) and a fixed picture window (MG-350 PW), which can also be made in arches, circles and other shapes
Impact: Every MG-350 model is impact-rated under a Florida Product Approval (FL41887 single-hung, FL41890 slider, FL41889 picture window)
Finishes: Powder-coat finishes in standard and custom colors

Full details

The MG-350 series shares one slim 2-3/16 in. aluminum frame across a single-hung (MG-350 SH), a horizontal slider (MG-350 HR) and a fixed picture window (MG-350 PW), which can also be made in arches, circles and other shapes. Mr. Glass describes it as having a slimmer sightline and a larger daylight opening. Compared with the heavier MG-200/300/400 windows, it offers one 5/16 in. laminated glass build, smaller maximum sizes and lower pressure ratings (+65/−80 psf on the single-hung, ±65 psf on the slider and picture window), so it fits standard openings rather than tall or high-wind ones.

Why it costs what it does: The lowest-cost Mr. Glass windows for the same opening: a slimmer frame, a single 5/16 in. laminated glass build, smaller sizes and lower pressure ratings.
Impact: Every MG-350 model is impact-rated under a Florida Product Approval (FL41887 single-hung, FL41890 slider, FL41889 picture window). The approval drawings note large- and small-missile resistance; there is no separate small-missile product.
Thermal: No thermal break, and the approval drawings show no insulated-glass option. NFRC-simulated U-factors are about 1.02-1.09 with laminated glass.
Finishes: Powder-coat finishes in standard and custom colors. AAMA 2604 paint is standard and AAMA 2605 is the upgrade. Under the October 1, 2025 Mr. Glass warranty (owner-occupied homes), both carry a 10-year finish warranty, but only AAMA 2605 stays covered within 2 miles of the coast or any salt water.

Series: MG-350 SH, MG-350 HR, MG-350 PW

Residential Impact Windows

Mid-range

Best for: Homes, condos and high-rise units that need taller or wider windows, higher wind-load ratings, insulated glass, casements or window walls.

This is the core of Mr. Glass's residential catalog
Impact: All are impact-rated under Florida Product Approvals
Finishes: Powder-coat finishes in standard and custom colors

Full details

This is the core of Mr. Glass's residential catalog. The MG-200 single-hung, MG-300 horizontal slider and MG-400 picture window share matching 2-7/8 in. frames and offer 7/16 in. SentryGlas and insulated-laminated glass, with ratings from about +80/−140 to ±100 psf. The MG-450 is a heavy fixed window that can be built very tall, with intermediate bars or combined with impact louvers. The MG-250 is a 6 in. deep stacked single-hung window wall for floor-to-ceiling and high-rise openings. The MG-600 is Mr. Glass's only crank-out casement and awning window. MG-150 aluminum mullions join units into larger openings.

Why it costs what it does: Costs more than the MG-350 series for the same opening because of deeper frames, thicker and insulated glass options, larger sizes and higher ratings. Within the family, the MG-250 window wall, MG-450 tall fixed window and MG-600 casement/awning cost the most.
Impact: All are impact-rated under Florida Product Approvals. The MG-200, MG-250, MG-300 and MG-450 have separate large-missile (LMI) and small-missile (SMI) approvals. The MG-400 and MG-600 are LMI approvals whose drawing notes cover large and small missile.
Thermal: No thermal break. With insulated-laminated Low-E glass, NFRC-simulated U-factors drop to about 0.56-0.78; with laminated-only glass they are about 1.01-1.14. The MG-250 has no published NFRC values.
Finishes: Powder-coat finishes in standard and custom colors. AAMA 2604 paint is standard and AAMA 2605 is the upgrade. Under the October 1, 2025 Mr. Glass warranty (owner-occupied homes), both carry a 10-year finish warranty, but only AAMA 2605 stays covered within 2 miles of the coast or any salt water.

Sliding, French and Entry Doors

Best for: Homeowners replacing patio sliders, French doors or a front entry door, from everyday budgets to statement pivot doors.

Sliding doors come in three levels: the slimmer MG-1500 two-track door with 7/16 in. glass, the heavy-duty MG-1000 two-track door with 9/16 in. glass and panels up to 12 ft, and the MG-1100 three-track multitrack door for very wide openings
Impact: Every door is impact-rated under a Florida Product Approval
Finishes: Powder-coat finishes in standard and custom colors

Full details

Sliding doors come in three levels: the slimmer MG-1500 two-track door with 7/16 in. glass, the heavy-duty MG-1000 two-track door with 9/16 in. glass and panels up to 12 ft, and the MG-1100 three-track multitrack door for very wide openings. Swing doors run from the MG-3000 outswing single or French door with sidelites, to the MG-3500 modern entry door with a 4-point lock and decorative panels, to the MG-4000 oversized pivot door up to 6 x 12 ft. The MG-2500T is a flush (coplanar) solid-panel door with concealed hinges, offered outswing or inswing.

Why it costs what it does: Cost varies widely within this line. The MG-1500 slider and MG-3000 French door are the lowest-cost Mr. Glass doors; the MG-1100 multitrack and the MG-4000 pivot door are the most expensive. Ask us for a side-by-side quote.
Impact: Every door is impact-rated under a Florida Product Approval. The MG-1000, MG-1100 and MG-1500 have separate LMI and SMI approvals; the MG-3000, MG-3500 and MG-4000 are LMI approvals; the MG-2500T approval covers LMI and SMI.
Thermal: Only the MG-2500T is thermally broken (glass-fiber-reinforced polyamide strips); it has no published NFRC values. The other doors are not thermally broken, with NFRC-simulated U-factors of about 0.66-0.67 with insulated glass and about 1.0-1.16 with laminated glass.
Finishes: Powder-coat finishes in standard and custom colors. AAMA 2604 paint is standard and AAMA 2605 is the upgrade. Under the October 1, 2025 Mr. Glass warranty (owner-occupied homes), both carry a 10-year finish warranty, but only AAMA 2605 stays covered within 2 miles of the coast or any salt water. The MG-2500T also offers a wood-look sublimation finish (5-year finish warranty), and the MG-3500 offers decorative solid infill designs.

Mr. Glass single-hung windows

Cost position

MG-350 SHSingle-hung window
Budget-friendly
The lowest-cost Mr. Glass single-hung: a slimmer 2-3/16 in. frame, a single 5/16 in. laminated glass build, smaller maximum sizes and a lower +65/−80 psf rating, with no SMI or insulated-glass version.
MG-200Single-hung window
Mid-range
Costs more than the MG-350 SH for the same opening, even with the same 5/16 in. glass: a deeper 2-7/8 in. frame, Ultralift balances, ratings up to +80/−140 psf, sizes to 96 in. tall, an SMI version, and 7/16 in. SentryGlas and insulated-glass options. Choosing 7/16 in. or insulated glass adds more. The MG-250 window-wall single-hung costs more than either.

Relative to other Mr. Glass single-hung windows, never a price. Your written estimate gives the price for your openings.

MG-200 vs MG-350 SH: which Mr. Glass single-hung?

MG-1500 vs MG-1000 vs MG-1100: which Mr. Glass sliding door?

The MG-1500 is the value slider. It has a 5 in. frame, 7/16 in. laminated glass, panels up to 48 x 108 in., and +65/−80 psf (LMI). The MG-1000 is the heavy-duty two-track door. It uses 9/16 in. laminated or 1-3/16 in. insulated laminated glass, takes panels up to 48 x 144 or 72 x 96 in., and is approved to +120/−140 psf. The MG-1100 adds a third track for up to six panels of 60 x 120 in., with the same glass choices and a +80/−100 psf rating. Cost rises in that order: thicker glass, bigger panels, more tracks and higher pressure.

design pressurepsfDesign pressure (psf)The wind load a window or door is approved to resist, in pounds per square foot (psf). A rating like +80/−140 psf gives the inward push (+) and the outward suction (−).Each opening on your home has a required pressure based on wind speed, height and location. The product must meet or exceed it, so a higher rating covers more openings.

LMIlarge missilelarge-missileLarge missile impact (LMI)A test in which a 9 lb piece of 2x4 lumber is fired at the glass and frame, followed by thousands of wind-pressure cycles. The unit must stay closed and in one piece.The Florida Building Code requires large-missile protection for openings up to 30 ft above ground in the windborne-debris areas that include South Florida.

SMIsmall missilesmall-missileSmall missile impact (SMI)A test with small steel balls that simulate roof gravel, followed by wind-pressure cycles.Openings more than 30 ft above ground, such as high-rise condos, need small-missile protection. Some products are approved for both.

HVHZHigh-Velocity Hurricane ZoneHigh-Velocity Hurricane Zone (HVHZ)Miami-Dade and Broward counties, where the Florida Building Code applies its strictest testing and approval rules.A product used in the HVHZ must be approved for it. Some products are approved only for outside the HVHZ, so they cannot be used in Broward or Miami-Dade.

NOANOAsNotice of Acceptance (NOA)A product approval issued by Miami-Dade County after independent testing. It lists the approved sizes, glass, pressures and installation details, and it has an expiration date.Your permit needs a current approval for the exact product. An NOA is the standard proof in the HVHZ.

Florida Product ApprovalFlorida Product ApprovalsFlorida Product Approval (FL number)A statewide product approval from the Florida Building Commission, shown as a number like FL42522. Its installation drawings set the approved sizes, glass and anchors.Every window and door installed under a Florida permit needs an approval, either a Florida approval or a Miami-Dade NOA.

laminated glassLaminated glassTwo layers of glass bonded to a plastic interlayer. If the glass breaks, the pieces stay attached to the interlayer and the opening stays closed.Laminated glass is what makes an impact window impact-resistant. It also blocks most UV and reduces outside noise.

insulated laminatedinsulated glassInsulated laminated glassA laminated glass layer paired with a second pane, separated by a sealed space often filled with argon gas.It keeps heat out and the air conditioning in far better than laminated glass alone, and it is quieter. It costs more and makes the unit heavier.

PVBPVB interlayerPolyvinyl butyral, the standard flexible plastic layer inside laminated glass.PVB meets most residential needs at a lower cost. Higher pressures or larger sizes may call for SentryGlas.

SentryGlasSGPSentryGlas (SGP)A stiff, strong ionoplast interlayer made by Kuraray, used in place of PVB in laminated glass.It is much stiffer than PVB, so it often allows higher pressure ratings and larger sizes, and it stays clear at exposed edges. It usually costs more.

heat-strengthenedHeat-strengthened (HS) glassGlass heated and cooled under control to be about twice as strong as ordinary glass. It breaks into larger pieces than tempered glass.Approval drawings often call for HS glass inside laminated units to reach their pressure ratings.

temperedTempered glassGlass treated with heat to be about four times stronger than ordinary glass. When it breaks, it crumbles into small, blunt pieces.It is used as the outer pane of many insulated units and wherever safety glass is required.

Low-Elow-ELow-E coatingA microscopically thin metal coating on the glass that reflects heat while letting light through.In South Florida it cuts the sun’s heat coming in, lowering cooling costs and protecting floors and furniture from fading.

U-factorU-factorsU-valueU-valuesU-factorHow much heat passes through the whole window. Lower numbers mean better insulation.A lower U-factor keeps cooled air in, which matters most with insulated glass.

SHGCSolar Heat Gain Coefficient (SHGC)The share of the sun’s heat that passes through the window, from 0 to 1. Lower numbers let in less heat.In Florida’s climate, SHGC is often the energy number that matters most for comfort and cooling costs.

VLTVisible light transmittance (VLT)The share of visible daylight that passes through the glass. Higher numbers mean brighter rooms.It shows the trade-off between a darker, cooler tint and natural light.

NFRCNFRCThe National Fenestration Rating Council, an independent organization that certifies window energy ratings such as U-factor and SHGC.NFRC-certified numbers are tested the same way for every brand, so they can be compared fairly.

thermally brokenthermal breakthermal breaksThermally broken frameAn aluminum frame split by an insulating strip so heat cannot travel straight through the metal.Aluminum conducts heat well. A thermal break keeps the inside of the frame cooler and improves energy performance.

KynarKynar (PVDF) finishA high-performance fluoropolymer paint based on Kynar 500 PVDF resin. It is the classic finish that meets AAMA 2605.It resists fading, chalking and salt air best, which is why manufacturers recommend it near the coast.

AAMA 2605AAMA 2605The highest industry standard for painted aluminum, tested for 10 years of South Florida sun exposure.It is the best choice for strong sun and coastal homes, and some warranties require it near salt water.

AAMA 2604AAMA 2604A mid-level industry standard for painted aluminum, tested for 5 years of South Florida exposure. It is the standard powder coat on many impact windows.It performs well inland. Near the coast, a 2605 finish lasts longer.

anodizedanodizeAnodized finishA finish that hardens and colors the surface of the aluminum itself instead of painting it.It shows the metal’s natural look. Its warranty is often shorter than that of paint finishes.

mullionmullionsMullionA structural bar that joins two or more windows or doors into one larger opening.Mullions carry wind load too, so they need their own approval and anchoring.

egressEgressA window opening large enough for a person to escape through in an emergency.Building codes require an egress window in bedrooms, so the style and size you choose matter there.

sidelitesidelitesSideliteA narrow fixed glass panel beside a door.It adds light to an entry and must be approved together with the door.

transomtransomsTransomA fixed glass panel above a door or window.It adds height and light, and it must be approved as part of the assembly.

frame depthFrame depthHow thick the frame is from inside to outside, in inches.Deeper frames are usually stronger and reach larger sizes or higher ratings. They must also fit your wall opening.

argonArgon gasA safe, invisible gas sealed between the panes of insulated glass.It slows heat transfer better than air, improving insulation.

XOXXO/OXXO, OX and XOXCodes for sliding layouts seen from outside: X is a panel that slides and O is a fixed panel.The layout decides which side opens, which helps you plan furniture and walkways.
