Updated August 2026. Vinyl and aluminum can both be impact-rated in Florida. The frame choice is about the opening, the coast, and the approval, not a winner-take-all brand fight. Spec the assembly that matches your sizes and design pressures.

Quick answer

Vinyl is often chosen for insulation and lower maintenance on typical residential openings. Aluminum is often chosen for larger openings and slimmer sightlines. Both still need a Florida Product Approval or Miami-Dade NOA that matches the house. A 2026 twin of this topic is live; this page stays on the original URL.

How we spec it on Statewide jobs

  • Opening size: big sliders and picture units often want a stiffer frame. Measure first.
  • Salt: coastal aluminum needs a finish meant for salt. Ask what coating is on the bid.
  • Energy: vinyl frames usually insulate better. Aluminum needs a thermal break if energy is the priority. We do not promise a bill cut.
  • Code: HVHZ vs wind-borne debris region changes the paperwork, not the marketing name of the frame.
  • Install: CBS waterproofing still matters. See block waterproofing.

We do not claim other manufacturers use weaker glass. Compare the approval documents.

FAQ

Is aluminum always stronger?

It is stiffer in many large-opening designs. Strength on your house is the tested assembly, including glass and anchors, not the word aluminum by itself.

Does vinyl yellow or fail in Florida sun?

Quality varies by line. Ask what the warranty covers for color and weld integrity. Do not assume every vinyl unit is the same.

Can I mix vinyl and aluminum?

Sometimes, if each opening has its own approval and the HOA accepts both finishes. Put that on the spec before you order.
