Impact French doors: elegance that holds the storm out

A French door is a hinged door — usually a matched pair — built almost entirely of glass, so it opens your living space to a patio, pool deck, or garden in one sweeping motion. In Palm Beach County, that indoor-outdoor flow is much of the point of living here. Impact French doors keep it and add a laminated-glass barrier rated to survive a major hurricane — no shutters to wrestle onto a track, no plywood, and no scramble when a system spins up in the Atlantic.

Unlike a sliding patio door that glides on a track, a French door swings, which gives you a wider clear opening per panel, a more traditional architectural look, and hardware that locks the slabs tight to the frame at multiple points. For coastal cottages, Mediterranean revivals, and new construction alike, a pair of impact French doors is often the detail that makes a rear elevation feel finished while quietly hardening one of the most vulnerable openings in the house.

Because the protection is built into the glass and frame, you get it every single day — not only during a storm. Laminated impact glass cuts outside noise by roughly half, filters out the UV that fades floors and art, and resists forced entry far better than an ordinary patio door. Pair the doors with impact windows across the rest of the home for a continuous line of protection that insurers reward and intruders avoid.

No two openings are identical, so impact French doors are built to fit. The choices below are the ones that actually change how a door performs against wind, water, and salt air on the Florida coast.

• Single or double: a single French door suits a den or secondary exit; a double — two slabs meeting at the center — opens a wide patio or lanai. Triple and four-panel layouts handle very wide spans.
• Inswing or outswing: coastal Florida often favors outswing doors, because wind pressure presses the slab tighter into its weatherstripping for better water resistance. Inswing works where a screen enclosure or porch is in the way — and both can be fully impact-rated.
• Sidelites and arched transoms: flanking glass sidelites and a radius or arched transom above the doors flood the room with light and deliver the signature Palm Beach look — all of it laminated and storm-rated, not just the door panels.
• Glass and grids: low-E coatings manage heat gain, while internal colonial or prairie grids, obscure privacy glass, and subtle tints let you match the architecture without breaking the impact seal.
• Frames: heavy-gauge aluminum gives slim sightlines and shrugs off coastal corrosion; vinyl and wood-clad options suit specific looks and budgets.
• Locking hardware: a multi-point lock and a reinforced astragal — the post where a double door meets — are what let two swinging slabs pass a large-missile test. It is the difference between a pretty door and a protective one.

Price depends on the size of the opening, single versus double versus arched configurations, glass and grid upgrades, and frame material, so we quote on-site rather than over the phone. As a rough guide, a single impact French door is a smaller project than a wide double unit with sidelites and an arched transom — and either one is an investment that can come back through a wind-mitigation insurance credit, lower energy bills, and added resale appeal.
