Searches for impact windows and doors usually come from a homeowner staring at a permit application or an insurance renewal. Neither document cares about marketing language. Both care about the same things a plan reviewer in any of the three counties cares about: the product approval on the window, the anchor schedule on the drawing, and whether the crew followed it. This page covers those three items the way we explain them on a jobsite walk.

Wind load, then everything else

We size openings from the wind load down. ASCE 7-22 sets the ultimate design wind speed; in the HVHZ counties that means 170 MPH and higher. The engineer converts that speed into design pressure for each opening, positive on the windward face and negative wherever suction develops. The window must be rated for that pressure and the anchors must transfer it into the wall. A rating on the glass alone means nothing if the frame pulls out of the block, which is why the approval, the anchor schedule, and the field installation all have to line up.

Installation is part of the rating

The tested assembly includes the anchors and their spacing. So in the field we treat the approval drawing as the install instruction: anchor type, spacing from the corner, spacing along the run, embedment into the substrate. The crew verifies the rough opening, checks that the masonry is solid where anchors land, sets the unit on shims, and drives anchors to the schedule. We photograph the anchor pattern before the exterior trim goes on, because the building official may ask for it and because it settles any argument later about what went in.

What people get wrong about **impact windows and doors**

That it is about the glass. It is about the assembly. That any licensed contractor can install it. Only a contractor who follows the anchor schedule and flashes the sill actually delivers the rating. That the rating is a single number. It is a positive and negative design pressure for a specific size, and the required number changes from wall to wall on the same house. We walk clients through their own elevation so the abstraction becomes specific.

Across the three counties

Miami-Dade and Broward are inside the High Velocity Hurricane Zone (HVHZ); Palm Beach County is outside it. That changes the paperwork more than the product: a Miami-Dade Notice of Acceptance (NOA) in the HVHZ, a Florida Product Approval (FL#) elsewhere. The design pressures from ASCE 7-22 are high across all three, and the salt exposure runs the length of the coast. We work in all three from our Hallandale Beach office.

The spec sheet, short version

6063-T6 aluminum extrusions. AAMA 2605 fluoropolymer (Kynar 500 resin) finish on any elevation facing the water; Class I anodic coating per AAMA 611 where the architect wants an anodized look. 316 stainless steel fasteners with isolating washers. Kuraray SentryGlas ionoplast interlayer for the stiffest laminate, 0.090" PVB interlayer where the approval allows it. Dow 995 at structural joints, Prosoco R-Guard FastFlash at the sill and jambs, Elco Ultracon+ or Hilti KWIK-CON II into masonry. Every one of those has a reason, and every one is on the shop drawing.

What goes wrong, and what we do instead

• Drilling a slab without locating tendons. Many South Florida slabs are post-tensioned. We scan with ground-penetrating radar before any floor anchor goes in.

• Anchoring too close to the block edge. A screw anchor near the edge of a hollow cell blows out the web and holds nothing. We hold the edge distance on the approval and grout cells where the anchor pattern demands it.

• Skipping the sub-sill pan. Water that gets past the weatherstrip has to go somewhere. Without a pan and a back-dam it goes into the wall. We install a pan or fluid-applied flashing under every sill, no exceptions.

Get the documents first

Ask us for the product approvals and the anchor plan for your house before you ask for a number. Then compare our proposal to anyone else's on those documents. That is how we prefer to win work.
