AfterSingle Hung Windows in Los Angeles, CA | Hale Windows & Doors
Single hung windows are one of the most common impact-rated replacement profiles we install in Florida homes, and for good reason. The design keeps the upper sash fixed while the lower sash lifts to open, which means fewer moving parts than a double hung and a tighter seal against wind-driven rain. At Hale Windows & Doors, we supply and install single hung impact windows from PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass across Los Angeles, CA. If you’re replacing older aluminum frames or a builder-grade window that flexes in a storm, this product deserves a close look. Call (252) 675-6980 to talk through your project.
Product Overview – Single Hung Windows
A single hung window pairs a fixed upper sash with an operable lower sash, both glazed in laminated impact glass. That fixed upper panel is a structural asset in hurricane-prone construction: there is no meeting rail that can flex or leak under negative pressure, and the frame carries the load as one continuous unit. In Los Angeles homes, this profile shows up everywhere from 1960s ranch houses to newer Mediterranean-style builds along the coast. It reads clean from the street, costs less than a comparable double hung because there is half the operable hardware, and still gives you the ventilation you need when the lower sash is open.
The engineering underneath matters as much as the curb appeal. We order these windows in aluminum or vinyl, depending on the structural requirements of the opening and the homeowner’s design preference. Aluminum handles larger spans and coastal corrosion better when finished correctly. Vinyl offers thermal isolation and a lower-maintenance surface. Both materials, when paired with laminated impact glass and the right anchoring package, create a system that stays in the wall when it matters. Hale Windows & Doors has installed this product line across Los Angeles, from beach-adjacent properties that face direct wind exposure to inland neighborhoods where energy performance drives the decision. One of the most common replacement profiles in Florida homes, and one we know how to install correctly.

Hurricane & Compliance Performance
Laminated Impact Glass
Two panes of glass bonded with a PVB interlayer. When impact occurs, the glass fractures but the interlayer holds the pieces in the frame, keeping the building envelope intact and blocking wind-driven debris. This is the core of the impact-rated system.
Miami-Dade NOA / Florida Product Approval
Each configuration carries a Notice of Acceptance and Florida Product Approval number. These are issued per specific size and glass package, which is why we verify the exact numbers on your quote before the permit application goes in.
FBC-HVHZ Compliance
Engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-load standard in the state, and the product line is built to meet it where the building department requires it.
TAS 201 / 202 / 203 Testing Context
The protocol family these products are tested under includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. That third test matters for security as much as storms.
Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100 PSF, never higher. We do not guess at this number. The structural calculations come from the site’s exposure category and building height, and the window order follows the math.
Energy Performance Options
Low-E and insulated glass packages are available for homes where cooling costs and UV exposure matter. In Los Angeles, where the sun works against the glass for much of the year, low-E makes a measurable difference in afternoon heat gain.
Color & Glass Options
The finish you choose should do two things: hold up to the coastal environment and look like it belongs on the house. White and almond remain the most common choices across Los Angeles because they match existing stucco and trim traditions cleanly. Bronze and black read more contemporary and hide grime better on busy streets or beachfront lots where salt haze settles. Tan splits the difference for warmer exterior palettes, particularly on Mediterranean and Spanish-revival homes. All five finishes are available in the impact series, and we can show physical finish chips at the measure appointment so you’re not guessing from a screen.
On the glass side, clear laminated impact glass preserves the truest light and is the most economical way to get hurricane protection. Tinted glass cuts glare and adds privacy on front-facing windows. Low-E insulated glass is the step up for energy performance: it reflects heat, reduces UV fading on floors and furniture, and still carries the impact rating where required. For Los Angeles homes with strong western exposure, we typically recommend Low-E on any window that takes afternoon sun. Your quote will line-item the glass package per opening so you can mix options where it makes sense.
Installation by Hale Windows & Doors in Los Angeles
The window is only half the system. A Miami-Dade NOA-rated product installed with the wrong fastener schedule or a sloppy perimeter seal will fail long before the glass ever gets tested. That is not hyperbole. The NOA is product-specific, and the anchoring method is part of the approval. If the installation does not follow the approved practice, the rating means nothing. This is why we handle the full installation in-house, trained and consistent, across every Los Angeles job we take.
Our process starts with a pre-install inspection of the rough opening. We check the condition of the surrounding framing, measure in three places on every side, and confirm the existing weather barrier before the window is ever ordered. On install day, the unit goes in level, plumb, and square, shimmed per the manufacturer’s approved method, and anchored to the structural substrate at the spacing the NOA requires. The perimeter gets a low-expansion foam sealant following AAMA 812 practice, then a perimeter sealant joint that allows for movement and water drainage. We install per AAMA 2400/2410 standards, which govern the full removal and replacement process from prep through final water test.
For Los Angeles homeowners, two things get extra attention. First, coastal exposure: salt air accelerates corrosion on exposed fasteners and hardware, so we specify the right material for the zone. Second, permitting: Los Angeles sits within HVHZ-adjacent wind zones, and some neighborhoods carry coastal high-velocity requirements that affect product selection. We know which jurisdictions require the NOA or Florida Product Approval submittal packet and we prepare that documentation for your permit. After installation, we run a final water test on a sample of openings, clean the site, and walk you through operation and maintenance. Professional installation is not an upsell on an impact window. It is the only way the rating survives the real world.
Frequently Asked Questions – Single Hung Windows
Design pressures are matched to your wind zone and capped at +/-100 PSF, never higher. The actual number for your home depends on the site’s exposure category, building height, and the specific window size. We calculate that from the structural plans and supply the matching product configuration, not the other way around. Call (252) 675-6980 and we’ll work up the exact number for your address.
Most single hung impact configurations run four to eight weeks from approved order to delivery in the Los Angeles area, depending on the manufacturer and glass package. Custom finishes or unusual sizes can push the upper end of that range. We confirm lead times at the time of quote and lock the install date once the windows hit our warehouse. Call (252) 675-6980 for a current estimate on your configuration.
Yes, in most Los Angeles permitting jurisdictions your permit package must include the NOA or Florida Product Approval number that matches your specific window size and glass configuration. We pull that documentation per opening and include it in the submittal we prepare for you. This is not something to reverse-engineer after the fact. Call (252) 675-6980 and we’ll tell you exactly what your building department will ask for.
Sizes are cut to the rough opening within the tested limits of the NOA. You can choose frame material, finish color, glass package, and screen configuration. What you cannot do is push the window beyond its tested size range without losing the impact rating, and we will not install a configuration that cannot carry the paperwork. Tell us what you’re working with and we’ll spec it correctly. Call (252) 675-6980.
Wash the track with mild soap and water twice a year, and clear the weep holes so drainage stays open. Do not use petroleum-based lubricants on vinyl or powder-coated aluminum; a dry silicone spray on the balance and track once a year is enough. If the sash ever feels stiff or the balance is sluggish, call us before forcing it. Call (252) 675-6980 for service or maintenance questions.
