Casement Windows

Casement Windows in Los Angeles, CA | Meridian Windows & Doors

Casement windows open outward on side hinges with a smooth crank mechanism, and in Los Angeles they’re one of the most practical impact-rated options we install. They’re built for two things Florida homes need constantly: airtight sealing against wind-driven rain and full, unobstructed ventilation when the weather turns mild. We install casement windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we’ve fitted them in homes from the Hollywood Hills to Westchester. Every casement we put in is level, plumb, square, and sealed to hold up under coastal exposure. Call us at (817) 686-2228 to talk through your project or schedule a free on-site measurement.

Product Overview – Casement Windows

A casement window is a side-hinged sash that cranks outward, and instead of sliding along a track like a horizontal roller, it closes against the frame itself. That’s the detail that matters most in hurricane-prone building. When the sash closes, the entire perimeter presses into a compression seal, which means the window gets tighter as wind pressure increases. You don’t get that from a sliding window. You get a full, uninterrupted seal that blocks air, water, and noise far more effectively.

Architecturally, casements fit a wide range of Los Angeles homes. They’re common on mid-century builds in the Valley, Spanish-style homes in Los Feliz, and newer coastal construction in Playa del Rey. The crank mechanism gives you precise control over how far the sash opens, so you can direct breezes into the room instead of just letting air drift past. On upper floors or over kitchen sinks where a sliding window would be awkward to reach, a casement is often the cleanest solution.

The frames come in aluminum or vinyl, both engineered for long-term exposure to salt air and intense sun. Aluminum gives you slimmer sightlines and more glass area, which homeowners in Echo Park and Silver Lake often prefer for the look. Vinyl delivers excellent thermal performance and requires essentially no maintenance, which makes it a favorite for rental properties and busy households. Both materials carry the same impact-rated glass packages, so the choice is about aesthetics and budget, not protection level.

Meridian Windows & Doors has installed casement windows throughout Los Angeles for years, and we know how this product behaves in every wind zone the city covers. We measure, order to spec, and install with the same level of care whether it’s a single window replacement in Atwater Village or a full-home window package in Brentwood.

Technical Specifications

Here’s what you’re choosing from when you spec a casement window with us. Every configuration is ordered to your exact opening size and wind zone requirements.

• Frame materials: Aluminum or Vinyl
• Glass options: Laminated Impact Glass with PVB interlayer, Low-E Insulated Glass, Tinted Glass, Clear Glass
• Finish options: White, Almond, Bronze, Black, Tan
• Screen options: Fixed Screen or Retractable Screen
• Operation: Side-hinged, crank-operated sash
• Seal type: Full-perimeter compression seal
• Design pressure: Matched to your wind zone, up to +/-100 PSF, never higher
• Size range: Custom-manufactured per opening, no stock-size limitations

We order every casement window to the exact dimensions of your rough opening. There’s no forcing a stock size into an opening it doesn’t fit, which is a common shortcut that leads to air leaks and seal failures down the road.

Hurricane & Compliance Performance

Casement windows from the product lines we carry are built and tested for Florida’s High-Velocity Hurricane Zone. Here’s what each performance element actually does for your home in Los Angeles.

Laminated Impact Glass

The glass is built with a polyvinyl butyral (PVB) interlayer bonded between two panes. If debris strikes the window, the glass may crack, but the PVB holds the fragments in place, keeping the building envelope sealed and wind pressure from entering the home.

Miami-Dade NOA / FL Product Approval

Each casement configuration carries a Miami-Dade Notice of Acceptance and Florida Product Approval number. These numbers are issued per configuration, so your specific quote will list exactly which approvals apply to your window sizes and frame selections.

FBC / HVHZ Compliance

Engineered to Florida Building Code High-Velocity Hurricane Zone requirements, these windows meet the structural and impact standards that govern construction in South Florida and other HVHZ-designated areas. Los Angeles coastal zones benefit from this same level of protection.

TAS 201 / 202 / 203 Testing Context

HVHZ-rated products like these casements are tested under a protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. This is the testing framework that proves the window holds under repeated, sustained pressure, not just a single hit.

Design Pressure for Your Wind Zone

Design pressure ratings are matched to the wind zone where your home sits. We’ll never sell you a window with a higher DP rating than your zone requires, and we’ll never under-spec one either. The rating goes up to +/-100 PSF, which means the window is tested in both positive and negative pressure directions, exactly what hurricane wind loading demands.

Energy Performance

Low-E insulated glass options are available to improve thermal performance year-round. In Los Angeles, that means less heat gain through west-facing windows in the afternoon and better heat retention on cooler nights. Tinted glass is another option for rooms with direct sun exposure.

Color & Glass Options

Casement windows come in five finish options: White, Almond, Bronze, Black, and Tan. White is the most common choice across Los Angeles, especially on traditional and coastal homes in neighborhoods like Mar Vista and Culver City. Almond and Tan suit Spanish and Mediterranean exteriors where a softer warm tone blends with stucco walls and clay tile roofs. Bronze and Black are increasingly popular on modern builds in Hollywood and the Arts District, where dark frames create a clean architectural contrast against lighter siding.

Glass choice depends on what each room needs. Clear laminated impact glass preserves maximum light and looks indistinguishable from standard glass from inside the home. Low-E insulated glass adds a thermal barrier that pays off on south- and west-facing walls. Tinted glass cuts glare in rooms with large window banks or direct afternoon sun, and it pairs well with Bronze and Black frames. Whatever combination you choose, the structural impact rating stays the same, because the laminated layer is present in every option we spec for Los Angeles installations.

Installation by Meridian Windows & Doors in Los Angeles

A window is only as good as its installation. An impact-rated casement window carries impressive test numbers only when it’s set correctly, sealed correctly, and anchored correctly to the surrounding structure. We’ve seen what improper installation does in Los Angeles: windows that leak at the sill after the first winter storm, frames that shift because they weren’t shimmed plumb, and seals that fail because the perimeter foam was applied too thin or too thick.

Our installation process starts with a pre-install inspection of every opening. We check the rough opening dimensions, the condition of the existing framing, and any signs of moisture intrusion around the old window. If we find rotted wood or damaged flashing, that gets addressed before the new window goes in, because sealing a good window into a bad opening is a waste of your money.

We set every casement window level, plumb, and square before anchoring. Then we apply a perimeter seal using AAMA 812 low-expansion foam, which fills the gap between frame and rough opening without bowing the frame or stressing the glass. Installation practice follows AAMA 2400/2410 standards, which are the benchmark for proper window and door installation in the field. After the seal cures, we run a final water test on the opening, clean the site, and walk you through operation and maintenance.

For homes in HVHZ jurisdictions within Los Angeles and the surrounding area, we’re familiar with the permit submittal requirements and can provide the NOA and Florida Product Approval documentation your permit application needs. We won’t leave you guessing about paperwork.
