Single Hung Impact Windows

Single hung impact windows have a fixed upper sash and a lower sash that slides up, a familiar look in South Florida bedrooms. We install made-to-measure ES Windows units, fitted by an installation team with direct certification from the manufacturer.

How a single hung impact window works: the top sash stays fixed in the frame and only the bottom sash moves, sliding up and down so you choose how much air comes in at window height.

With one moving sash, the routine is simple: lift the lower sash for air, then lower and latch it before a storm. ES Windows places single hung in its Elite line, which ES describes as large and small missile impact rated and built for South Florida’s High Velocity Hurricane Zone.

Heat-strengthened glass and corrosion-resistant hardware are standard on Elite. To weigh it against other styles, start with our overview of impact windows for South Florida homes.

Usually, yes. Florida’s code requires an emergency escape opening in every bedroom, and a replacement can generally keep the same style when it is the largest standard size that fits the existing opening. We check each bedroom before ordering, and if you want a bigger clear opening we can price a side-hinged casement impact window.

ES Windows lists single hung in its Elite line, made for single-family homes, with a flush and flange frame for retrofit and concrete construction and a fin frame for wood construction. Units are made to measure, so the size comes from your opening and the product approval for it, not from a stock list. We confirm the series at your estimate.

USA Home Improvement fits aluminum and vinyl ES impact windows; whether vinyl comes in single hung at your size is confirmed at the estimate. Elite aluminum comes in anodized, painted or wood grain finishes. For a traditional look, Elite offers Colonial or Brittany glazing styles with flat or OG (ogee) grids; full-view glass leaves the pane clear.

Heat-strengthened glass is standard on Elite, and ES offers Low-E glass options by Tecnoglass to help manage the solar heat that comes through the pane. For a bedroom on a west wall, Low-E is worth pricing. Solarban 70 is a Low-E glass that ES lists for its Multimax line, so ask whether it is offered for the series you choose.

The number of openings, each window’s size, the frame material, the glass package and the finish all move the price. So does the work at the wall: taking out the old window and any repair found behind its frame. Every USA Home Improvement project is permitted, and HOA approval is added only when your property has an HOA.

Why Choose It

Simple and Sturdy

What a single hung impact window does for a South Florida home, from storm season to a quieter bedroom.

Storm-Ready Sash

Before a storm, you lower the moving sash and latch it, and the window is ready; there are no panels to carry out of the garage. Single hung units in the ES Elite line are large and small missile impact rated, so the window itself protects the opening.

Quieter Bedrooms

Impact glass in a sealed frame can reduce the street noise that reaches a bedroom, and ES lists reduced sound transmission as an Elite feature. How much you notice depends on the glass and on how loud it is outside, as our article on impact windows and household noise explains.

Less Heat Indoors

One fixed sash means only one sash has to seal as it moves. Paired with Low-E glass, the frame and pane together can help hold back the afternoon heat, so the air conditioning may not have to run as hard in summer.

Insurance Credits

Opening protection is one of the items a Florida wind mitigation inspection records, and some insurers give credits for it. Your insurer decides what applies to your policy, so ask them before the job starts. Keep the permit and each window’s Florida Product Approval number for that conversation.

Locked Lower Sash

On a single hung window, the lower sash is the only part that moves, so its lock is the one that matters. Check that it latches firmly every time the sash comes down, and lock it whenever you leave the house; ES lists sweep locks among its window hardware.

Stuck Lower Sash

Old single hung windows often bind in their tracks after years of salt air and repainting, so the sash will not lift or will not stay up. A replacement gives you a lower sash that moves and latches the way it should.

Drafts at the Rail

Where the two sashes meet, worn weatherstripping lets cooled air out and humid air in. If you can feel air or see light at that meeting rail, the seal has failed, and a new impact window brings a fresh seal.

Water at the Sill

Stains or soft wood under a window usually mean rain is getting past the sill or the frame. Left alone, that moisture can lead to mold, so the sill and framing get a close look when the old unit comes out.

Paying for the Job

Pay for Them Over Time

Whether you replace one single hung window or all of them, financing may be available for qualified homeowners through independent third-party providers. Where a local program covers your property, that can include PACE financing. Before your estimate, read how our financing options work, since terms, eligibility and availability depend on the program and location.
