Single Hung Windows

Single Hung Windows in Los Angeles, CA | Juniper Windows & Doors

Single Hung Windows are one of the most common impact-rated replacement profiles you’ll find in Florida homes, and for good reason. They pair a fixed upper sash with an operable lower sash in laminated impact glass, giving you ventilation where you want it and strength where the storm demands it. At Juniper Windows & Doors, we install Single Hung Windows across Los Angeles, CA, and we’ve done it long enough to know that the difference between a window that holds and one that fails is almost always in the installation. If you’re researching this product for a home or project in Los Angeles, call us at (682) 281-2168 and we’ll walk you through what fits your openings and your wind zone.

Product Overview – Single Hung Windows

Single Hung Windows have a simple, honest design: the top sash stays put, and the bottom sash slides up to open. That fixed upper sash is actually a structural advantage in hurricane-prone construction, because there’s one less moving joint and one more continuous seal against wind-driven rain. The operable lower sash rides in a track system that locks into place when closed, so the window isn’t just held by its edges – it’s engaged around the full perimeter.

What makes this profile suited to Florida’s building reality is the glass. We specify laminated impact glass with a PVB interlayer as the default, which means the glass is engineered to stay in the frame under impact rather than shattering into the room. That’s the core of what a Florida homeowner is buying when they choose an impact-rated Single Hung Window, and it’s the same principle that drives Multi-Slide, Casement, and Picture Window impact products across the industry. Architecturally, Single Hung Windows read as clean and traditional, which is why they work so well in the ranch homes, mid-century boxes, and 1980s concrete-block houses that fill so many Los Angeles neighborhoods. They replace aluminum builder-grade windows without changing the look of the house, but they completely change how the house performs in a storm.

Juniper Windows & Doors installs this product across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so we can match the right frame, finish, and glass package to the job rather than forcing one brand onto every opening.

Technical Specifications

Every configuration we quote for Los Angeles projects is built to order, so you’re not picking from a limited stock list. Here’s what we’re working with:

• Frame Materials: Aluminum or Vinyl. Aluminum gives you the slimmest sightlines and the most modern look; vinyl gives you thermal efficiency and a lower price point.
• Glass Options: Laminated Impact Glass (PVB Interlayer), Low-E Insulated Glass, Tinted Glass, or Clear Glass. These can be combined – for example, a laminated outer lite with a Low-E insulated inner lite.
• Color and Finish Options: White, Almond, Bronze, Black, and Tan. Finishes are applied in the factory, not painted on site.
• Screen Options: Half Screen or Full Screen. Half screens cover the operable lower sash only; full screens cover the entire opening for a cleaner look when the window is open.
• Design Pressure: Matched to your wind zone, up to +/-100. We never over-spec beyond what the opening actually requires.
• Compliance Documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration, verified on your specific quote.

Hurricane & Compliance Performance

Laminated Impact Glass
The heart of this window is the laminated glass. A PVB (polyvinyl butyral) interlayer is bonded between two panes of glass, so if the outer pane takes a hit, the interlayer holds the glass in the frame. That’s the mechanism that keeps wind, rain, and debris out of your house during the storm, and it’s the same technology used in automotive windshields.

Miami-Dade NOA / Florida Product Approval
Each configuration we install carries a Miami-Dade NOA (Notice of Acceptance) or Florida Product Approval number. These are issued per configuration, meaning the specific frame, glass, and size combination you choose has been through the testing protocol. We verify the applicable numbers on your specific quote before anything gets ordered.

FBC / HVHZ Compliance
Our Single Hung Windows are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ is the strictest wind-load standard in the state, and it governs Miami-Dade and Broward counties. Even if your Los Angeles property falls in a different wind zone, the product is built to the higher bar.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a specific protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These are the tests that make an NOA number meaningful. When we cite a product approval, this is the testing that stands behind it.

Design Pressure Matched to Your Wind Zone
We match design pressures to your wind zone, up to +/-100, and never higher. Design pressure is a PSF (pounds per square foot) rating that tells you how much positive and negative wind load the window can handle. Over-specifying above your actual requirement adds cost without adding safety, so we don’t do it.

Energy Performance Options
Low-E and insulated glass options are available for homeowners who want to cut heat gain and improve comfort. In Los Angeles, where the afternoon sun can bake a west-facing wall, a Low-E insulated configuration makes a real difference in how the room feels, and it pairs naturally with the impact-rated outer lite.

Color & Glass Options

Finish and glass choices matter more in Los Angeles than most people expect. The city’s housing stock runs from 1950s ranch homes to Spanish-style villas to contemporary builds, and the right window color either blends in or stands out in exactly the way you want.

White and Almond are the safe, classic picks for stucco homes – they match the existing trim on most Los Angeles houses and keep a clean, bright look. Bronze and Black read more modern and work beautifully on homes with darker trim, wood accents, or a more architectural aesthetic. Tan splits the difference, pairing well with earth-tone exteriors and natural stone. For glass, Clear is the baseline, Laminated Impact is the standard for storm protection, Tinted cuts glare on south-facing rooms, and Low-E Insulated gives you the best year-round energy performance. Most of our Los Angeles clients combine laminated impact glass with a Low-E insulated inner pane, which gives both hurricane protection and thermal comfort in one unit.

Installation by Juniper Windows & Doors in Los Angeles

Here’s the thing about impact windows: a Miami-Dade NOA rating applies to the product as tested, which includes how it’s installed. A window that’s not set level, plumb, and square, or that’s sealed with the wrong product, won’t perform to its design pressure. That’s why we treat installation as part of the compliance chain, not an afterthought.

Our process in Los Angeles starts with a pre-install inspection. We measure the actual rough openings, check the condition of the existing frames and surrounding stucco or siding, and identify any structural issues before we order anything. When the windows arrive, we set each unit level, plumb, and square, shimming where necessary and fastening to the manufacturer’s published schedule. We install per AAMA 2400/2410 practice, which governs the installation of windows and sliding doors in exterior walls. The perimeter gets an AAMA 812 low-expansion foam sealant – the right product to air-seal and water-seal without distorting the frame. After each unit is in, we run a water test, clean up the site, and document the work for your permit file.

Los Angeles has its own considerations. Many neighborhoods sit close enough to the coast that salt air is a real factor in frame and hardware choices. Wind zones vary across the city and county, so we verify the design pressure requirement for your specific address rather than assuming. And if your project is in an HVHZ jurisdiction, we make sure the NOA numbers on your permit submittal match the exact windows going into the openings. Permitting is part of the conversation from day one, not something we figure out later.
