Frequently Asked Questions
The Single Hung 250 is a single-hung window with a fixed top sash and a movable bottom sash, which is the most common operation style on Florida homes. Air Master builds it in the Series 250 line specifically for residential replacement projects across the state. We install it for homeowners who want a familiar, easy-operating window with laminated glass.
No. The Single Hung 250 carries Florida Product Approval (FL21457.R5) but is not High-Velocity Hurricane Zone (HVHZ) approved, so it cannot be used in Miami-Dade or Broward by itself. It is intended for replacement projects in the rest of the state. If your home is in an HVHZ jurisdiction, Air Master's Series 250 Sliding and Fixed windows hold Miami-Dade Notices of Acceptance, and we can review the right option with you at quote.
In its O/X single-hung configuration the Single Hung 250 builds up to 47.69 inches wide by 35.94 inches tall, rated at a design pressure of +73.7/-73.7 psf. We confirm the exact size and rating for your opening when we measure for your free estimate.
The Single Hung 250 uses up to 5/16-inch laminated impact glass, built as an insulated unit with a 0.090-inch Saflex CP PVB interlayer between annealed lites. That laminated construction is the same type of glass that resists impacts, which is why this window carries an LMI impact rating. We help you choose the glass that fits your project and confirm the build at quote.
The insulated laminated glass package on the Single Hung 250 is rated at a U-factor of 1.06, an SHGC of 0.64, a visible transmittance of 0.7, and a condensation resistance of 13. The aluminum frame comes standard in White, Almond, Grey, Bronze, and Chocolate, with more than 200 custom colors available, and glass tints include Clear, Bronze, Solex, Ice Glass, and Frosted. We'll go over finish and tint choices so the window matches your home.
We don't quote a flat price because installed cost depends on the size of the opening, the glass package and tint you choose, the frame finish, and the condition of the existing opening. The Single Hung 250 is part of Air Master's Standard Windows line built for Florida replacement projects. Armor Pro provides a free, no-obligation estimate after measuring your openings so the price reflects your actual project.
This line is the one Air Master family with HVHZ-capable products. The Series 250 Sliding (horizontal roller) and the Series 250 fixed Picture Window hold Miami-Dade Notices of Acceptance, so we can permit and install those two styles in the High-Velocity Hurricane Zone that covers Miami-Dade and Broward. The Projected Out (awning) and Single Hung 250 carry Florida Product Approval for the rest of the state but not a Miami-Dade NOA, so we use them outside the HVHZ. We confirm the right style for your address and county before we quote.
Four styles cover most South Florida replacement work: Picture (a fixed pane for daylight and views), Projected Out (an awning that vents in light rain), Single Hung 250 (a fixed top sash over a movable bottom sash, the most common style on Florida homes), and Sliding (a horizontal roller for wider openings). All four are aluminum-framed with laminated impact glass. We help you match the style to each opening so the look and the airflow fit how you use the room.
Yes, but only on specific products. Air Master's Series 250 aluminum line — fixed window, horizontal-slider window, sliding glass door, and swinging door — carries a Miami-Dade Notice of Acceptance (NOA) and is rated for the High-Velocity Hurricane Zone that covers Miami-Dade and Broward counties. The rest of the residential catalog carries statewide Florida Product Approval, which is accepted across most of Florida but not inside the HVHZ. We confirm the right product for your county before we quote.
