AfterFrench & Double Doors in Los Angeles, CA | Sightline Windows & Doors
French and double doors bring something no sliding panel can: a wide, symmetrical opening that makes a room feel larger and more connected to the outdoors. Sightline Windows & Doors supplies and installs paired impact-rated French doors engineered for Florida’s High-Velocity Hurricane Zone, with laminated impact glass in every lite and multi-point locking hardware. We serve Los Angeles, CA homeowners who want the classic look of French doors without compromising on storm protection. If you’re planning a project, call (509) 265-6387 and we’ll walk you through configurations, pricing, and lead times.
Product Overview - French & Double Doors
Our French and double doors are built as a matched pair: two active or one active/one fixed panel that swing open from a center line, creating a clean, balanced sightline from indoors to out. The profile is unmistakable. Slim stiles and rails frame each glass lite, letting light move through the door while keeping the hardware profile minimal. Unlike a standard patio door, French doors read as intentional architecture rather than a utility opening.
What sets this product apart in a hurricane market is that every lite carries laminated impact glass with a PVB interlayer. That means the glass is not just tempered and hoped for the best. It’s engineered to hold together and stay in the frame under impact, protecting your interior from wind-driven debris and pressure changes. The frame is available in aluminum or vinyl, both extruded to accept the heavier laminated glass packs without sagging at the hinge points.
Hardware matters on a door this size. We spec multi-point locking mechanisms that engage at the head, sill, and meeting stile, not a single latch at the handle. That spreads the locking force across the full height of the panel and helps the doors resist pressure flexing during a storm. For Los Angeles homeowners working with Mediterranean, coastal, and modern farmhouse elevations, this door profile fits naturally where a slider would feel too contemporary.
Technical Specifications
- Frame materials: Aluminum or vinyl, both engineered for paired-door weight and repeated cycling
- Maximum size: Up to 96 inches wide across the pair, height per configuration

Every configuration gets a design pressure rating matched to your specific wind zone in Los Angeles, up to +/-100 PSF, never higher. We do not over-spec a door for a zone it will never see, and we never undersell a configuration that needs the full rating. Your quote spells out the exact DP rating for your opening.

Laminated Impact Glass
Every lite in our French and double doors carries laminated glass with a polyvinyl butyral interlayer. Under impact, the glass cracks but the PVB holds the fragments in place, keeping the building envelope sealed. This is the same glass technology used in automotive windshields, scaled for residential door openings.
Miami-Dade NOA / FL Product Approval
The door configurations we sell carry Miami-Dade Notice of Acceptance and Florida Product Approval documentation, issued per configuration. That means the specific combination of frame, glass, size, and hardware you choose has been reviewed and approved as a system. We provide the approval numbers on your quote so your permit submittal in Los Angeles goes through cleanly.
FBC / HVHZ Compliance
These doors are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-bearing standard in the state, applied to coastal and high-wind regions. A door built and tested to that standard is doing more than meeting a generic coastal code.
TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact resistance: a length of lumber fired at the glass at speed. TAS 202 covers cyclic wind-pressure loading: repeated pressure cycles that simulate a hurricane’s fluctuating forces. TAS 203 covers forced-entry resistance, which doubles as a security feature. This is the test battery behind the approval numbers.
Design Pressure for Your Wind Zone
We match design pressure to your Los Angeles wind zone, up to +/-100 PSF, never higher. Design pressure is a structural rating, not a wind-speed claim. If your opening calculates to a lower requirement, we quote the configuration that meets it. You will never pay for unnecessary over-engineering, and you will never get a door under-spec’d for your exposure.
Energy Performance
Low-E and insulated glass options are available on these doors. Low-E coatings reduce solar heat gain through the glass, which matters on west-facing Los Angeles exposures and rooms with heavy afternoon sun. Insulated glass adds a second air space for thermal separation. Both options work with the laminated impact outer lite.
Color & Glass Options
Finish selection is where the door either matches the house or becomes a focal point. White frames stay classic and bright against coastal exteriors and crisp stucco. Almond and Tan work well on warmer Mediterranean and Spanish Revival homes common in parts of Los Angeles. Bronze and Black read more contemporary, pairing cleanly with dark window frames, charcoal roofs, and modern elevations. The finish on both panels is matched at the factory, so the pair reads as one unit even under direct sunlight.
For glass, clear glass is the default choice when you want maximum visibility and the least color shift. Tinted glass cuts glare and solar heat gain, a practical option for doors facing strong western sun in Los Angeles. Low-E insulated glass is the energy-performance choice, combining a low-emissivity coating with an insulating air space. All glass options are available in laminated impact form, so the storm protection stays consistent regardless of which look or performance level you pick.
Installation by Sightline Windows & Doors in Los Angeles
An NOA-rated door only performs if the installation honors the opening. That is the honest truth about hurricane products, and it’s why we install every French and double door the same way on every Los Angeles job.
We start with a pre-install inspection of the rough opening. We look at the substrate, the fastening plane, and how the existing flashing ties into the wall assembly. If the opening is not square or the framing is compromised, we flag it before the new door goes in, not after. The door is set level, plumb, and square, with shims at the hinge and lock points so the panels swing clean and the multi-point hardware engages without fighting the frame. We use AAMA 812 low-expansion foam around the perimeter for a continuous air seal, then flash and cap the exterior per AAMA 2400 and 2410 installation practice.
In Los Angeles and the surrounding coastal area, we pay extra attention to the sill pan and drainage plane. Salt air is hard on aluminum and hardware. A poorly flashed sill will trap moisture and quietly rot the subfloor, and no NOA approval number saves a door installed over a compromised rough opening. We also know what each HVHZ jurisdiction wants to see at permit time, and we can coordinate the approval documentation with your permit submittal. Water test on the finished sill, hardware cycle test, and a walk-through of operation and maintenance close out every install.
Frequently Asked Questions - French & Double Doors
The design pressure is matched to your specific Los Angeles wind zone, up to +/-100 PSF, never higher. We calculate the required DP for your exact opening size, exposure, and location, then quote the configuration that meets it. Call (509) 265-6387 and we’ll confirm the rating for your address before you commit to anything.
Lead time varies by configuration, glass package, and finish. Aluminum frames typically run longer than vinyl, and custom color matches add time. When you request a quote, we give you a written lead-time estimate on the same sheet as the price, so you can plan your project schedule realistically. Call (509) 265-6387 for current timelines on your specific configuration.
In most HVHZ jurisdictions in and around Los Angeles, yes. The building department will want the approval documentation for the exact configuration you are installing. We provide the NOA and Florida Product Approval numbers on your written quote, and we can print the approval drawings and test reports for your permit package. It is one less thing for you to chase.
Within the engineering limits of the product line, yes. The system maxes out at 96 inches wide, but within that envelope you can adjust panel widths, choose between double active or active/fixed operation, and select your swing direction. We will not push a configuration into a size the approval does not cover. Everything we quote is documented as an approved system.
Rinse the frame and tracks with fresh water every few months if you’re near the coast in Los Angeles, where salt haze settles on aluminum and vinyl alike. Use a mild soap and water on the frame; avoid abrasive cleaners on the finish. Lubricate the hinge and multi-point hardware annually with a silicone-based lubricant, and check the weatherstripping at the meeting stile once a year. A door that gets the same basic care as your car will outlast the house.
