Horizontal roller impact windows

XO is two panels, one that slides and one that's fixed. XOX is three panels with a fixed center and a sliding panel on each end, so it suits very wide openings and lets air in from both sides. PGT's HR7710A comes in both, and OX is the mirror of XO.

No. We don't install XX rollers; impact rollers are typically XO/OX or XOX. XO or OX has one fixed and one sliding panel, and XOX has a fixed center and a sliding panel on each end. If you want the whole opening to open, a casement opens fully.

Yes, a roller is a good fit by a pool because it opens inside its own frame, so nothing swings out over the deck or walkway. Most pool-facing and patio openings we see are rollers or fixed glass, and the sliding sash stays out of the way of furniture and foot traffic.

Vacuum the loose sand and debris out of the sill track, then wipe it with a cloth or sponge and soap and water. That's PGT's own advice for rough-rolling sliders. Lubricate only with what the manufacturer allows, since PGT warns that some silicone aerosol sprays can damage plastic parts.

That's normal, because the sill is built to collect water and drain it out through weep holes at the bottom of the frame. PGT says those holes must stay clear and open, because if they're blocked the water can back up into the house. Clear them gently with a soft brush.

Neither is better everywhere; the shape of the opening decides. A roller suits wide, short openings and a single-hung suits tall, narrow ones, and each opens about half of the window in its two-panel form. On our price guide, single-hung is low and rollers are low to mid.

Yes, with a vent latch. PGT offers an optional vent latch on the HR7710A that lets fresh air in without opening the window all the way, and its low-profile sweep lock shows at a glance when the window is unlocked. Close and lock it fully before a storm.

Yes, if the sliding panel opens far enough. Florida code asks for 5.7 square feet of clear opening (5.0 on the ground floor), at least 20 inches wide and 24 inches high, with the sill no higher than 44 inches. In a small opening, a casement is often the only type that meets it.

Wide enough that the sliding panel clears 20 inches, which takes about 48 inches of width by PGT's formulas for the two-panel HR7710A. At that width it also needs about 48 inches of height for 5.7 square feet, or about 37 inches at 63 wide. An equal three-panel XOX needs about 72 inches. Exact openings vary by product and approval.

Often, yes. Florida code requires fall protection on operable windows when the bottom of the opening is less than 24 inches above the floor and more than 72 inches above the ground outside. A window opening control device certified to ASTM F2090 meets it, and PGT offers one on the HR7710A.
