Impact-Rated Double-Hung Window Replacement in South Florida
Double-hung replacement swaps both sashes and the balance system for a tilt-in, impact-rated unit that keeps the traditional look while meeting current Florida Building Code and ASCE 7-22 wind load requirements.
Sash & Balance System Engineering
Double-hung windows have two operable sashes that slide vertically, held in place by a balance system, either a block-and-tackle or a constant-force spiral, that lets the sash stay put at any height without the homeowner holding it up. Impact-rated double-hung replacements use a heavier-duty balance rated for the added weight of laminated glass, since impact glass runs noticeably heavier than standard annealed panes and a stock residential balance will wear out fast under that load.
Because the sash tilts inward on pivot pins, homeowners can clean the exterior glass surface from inside the home without a ladder, which matters most on second-story openings. Every impact double-hung unit installed here is glazed with laminated glass meeting Miami-Dade NOA impact standards, fitted with multi-point cam locks at the meeting rail, and sized to the existing masonry opening so trim and interior casing stay untouched.
Why Choose Six Senses Builders?
Our 4-Step Engineering & Installation Process
Sash Weight & Balance Sizing
The crew calculates sash weight with laminated glass installed and specs a balance system rated to carry that load smoothly at any stopped height without drift.
NOA-Rated Frame & Glass Order
Frame and glass are ordered together under a matched Miami-Dade NOA number so the sash, lock, and balance combination is documented for permit approval.
Removal, Set & Meeting Rail Alignment
The old double-hung unit is removed, the new frame is set and anchored, and both sashes are aligned so the meeting rail locks tight without binding.
Cam Lock Adjustment & Final Walkthrough
Cam locks and balance tension get adjusted so both sashes glide and lock cleanly, then the crew walks the homeowner through tilt-in cleaning before final inspection.
Impact-Rated Double-Hung Window Replacement in South Florida FAQs
❓ What's the difference between double-hung and single-hung windows?
Single-hung windows have one fixed top sash and one operable bottom sash. Double-hung windows let both sashes slide, and both tilt inward for cleaning. Double-hung units cost more because of the extra balance hardware, but most homeowners find the tilt-in feature on both sashes worth it, especially upstairs.
❓ Can double-hung windows still tilt in once they're impact-rated?
Yes. The tilt-in pivot function is unchanged by adding laminated impact glass, though the heavier sash means the pivot pins and balance hardware are upgraded to handle the added weight. Every unit installed here keeps full tilt-in access for cleaning from inside the home.
❓ How do I know if my house needs double-hung or single-hung replacements?
It usually comes down to matching what's already there, since mixing styles on one elevation looks off from the street. If the existing windows are double-hung, the replacement should be too. A site visit confirms sash count and rough opening size before ordering.
