Frequently Asked Questions
The Old San Juan is Air Master's signature casement, featuring an arched glass top inspired by the historic San Juan district architecture. It can be ordered with an optional operable insert sub-window, in Master Guard, Italic, or Storm Guard blade styles, for moderated ventilation. We install it for homeowners who want a distinctive arch-top casement with Air Master's Caribbean styling.
Yes, in part. The Old San Juan is offered in two series: the Lineal series, which is impact-rated (large-missile impact), and the 2500 series, which is non-impact, so the right one depends on your installation needs. The window itself is not HVHZ approved, so for openings governed by Miami-Dade or Broward High-Velocity Hurricane Zone rules we'll review whether it can be permitted or whether the Florida-approved Full Glass Casement is the better fit. We confirm the series and rating at quote.
Yes. The Old San Juan can be configured with an optional operable insert sub-window in Master Guard, Italic, or Storm Guard blade styles, letting you ventilate through the insert without opening the full arch-top casement. The blade style you pick affects the airflow and storm resistance of the insert. We'll help you choose the insert option that suits how you want to use the window.
The Old San Juan's defining feature is its arched glass top, which Air Master designed in reference to the historic Old San Juan district architecture in Puerto Rico. It's the signature model in Air Master's casement family. We'll confirm the exact arch dimensions and configuration for your opening when we measure.
The Old San Juan is built on an aluminum casement frame, consistent with the rest of Air Master's casement line. The arch-top design and any optional insert are framed in that aluminum. We confirm available finishes and the full configuration with you during the measure for your free estimate.
We don't quote a flat price because installed cost depends on the size of the arched opening, whether you choose the impact-rated Lineal series or the non-impact 2500 series, any insert option, the finish, and the condition of the existing opening. As a signature arch-top casement, the configuration drives the cost. Armor Pro provides a free, no-obligation estimate after measuring your openings so the price reflects your actual project.
A casement is hinged on one side and cranks open outward, swinging away from the frame like a small door. Because the whole sash opens, you get full-aperture airflow, and when it's closed the sash presses tight against the frame for a strong weather seal. They suit spots where you want maximum ventilation or an unobstructed view. We can show you how a casement operates against the openings you're considering during the measure visit.
The Full Glass Casement is the one casement in this family that carries Florida Product Approval (FL #21455), built in aluminum with laminated impact glass for residential and light commercial use. The other casements in the line, including the French Casement, the two insert configurations, and the Old San Juan arch-top, are Caribbean-market styles that do not carry Florida certification. For a code-compliant Florida install we work from the Full Glass Casement; the rest are specialty configurations we handle case by case.
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.
