Single-Hung Impact Windows
The most-installed impact window on Florida homes: the bottom sash slides up, the top stays fixed, and the sash tilts in to clean from inside. Cost-effective, low-maintenance, and impact-rated to Florida code — installed by in-house Access Impact crews across South Florida.
Context
Single-hung impact windows are the most-installed style on Florida homes. The bottom sash slides up to open; the top sash is fixed. Against a casement they cost less per opening (simpler mechanism) and need less upkeep (no crank hardware); against a picture window they add ventilation.
For bedrooms, baths, and standard walls, single-hungs hit the right cost-to-performance balance — which is why most whole-home projects are built around them.
Where they fit
The default for standard residential openings where cost and reliability matter most.
When you're replacing every window, the single-hung is the value backbone of the project.
The tilt-in sash lets you clean the exterior glass from inside — no ladder on the upper floor.
Low maintenance and cost-effective per opening for properties you don't live in.
Specs + capabilities
Bottom-sash vertical slide with a counter-balance spring for smooth lift; tilt-in sash for cleaning from inside.

Multi-cam locking with a solid seal; pairs with Low-E glass for solar control.
Standard dimensions widely stocked; made to your opening where needed.
Authorized installer for the CWS and ES Windows lineups.
6–10 weeks for standard sizes — typically the fastest style to turn around.

Install considerations
Where single-hung impact windows installs go wrong — and how we get them right every time.
A single-hung lives on its counter-balance. We set and test the lift so the sash holds at any height and glides for years.
Single-hungs drain through weep holes at the sill; block them and water backs up. We keep the drainage path clear and tested.
A racked frame binds the sash and breaks the seal. Our crews set every unit plumb, level, and square before sealing.
Access Impact installs as a licensed Florida general contractor (CGC1525402). Every window and door we set is impact-rated to the Florida Building Code and carries a current Florida Product Approval — and, where your county requires it, a Miami-Dade Notice of Acceptance. We pull the permit, cite the product approval on your written quote, and back it with a 100% first-time inspection pass rate.
Common questions
On a single-hung the top sash is fixed and only the bottom moves; a double-hung has two moving sashes. Single-hung is the Florida standard — fewer moving parts, better sealing, lower cost.
Aluminum for coastal Florida (30+ year service life and strength); vinyl is a cost-effective choice for inland walls. We'll steer you based on your location.
Yes — the sash tilts in so you can clean the exterior glass from indoors, which matters on a second story.
Yes — laminated impact glass to the Florida Building Code with a Florida Product Approval or Miami-Dade NOA, the same protection standard as any impact window.
