R-301 Vinyl Patio Doors: Custom Sliding Systems for BC Homes
Engineered for the West Coast. Installed for Life.
Don’t just replace your view. Upgrade your home’s defense against rain, noise, and energy loss with a system built locally in Burnaby.
Most door failures don’t happen because of the vinyl; they happen because of the install. While other products might look good in the showroom, the A1 R-301 Series is engineered to perform where it counts: in your wall, during a November rainstorm. We deliver comfort, quality, and compliance without compromise.
Total Accountability: From Our Factory to Your Wall
Unlike big-box retailers or sales-only companies that sub-contract the hard work, A1 Windows manages the entire lifecycle.
- Made Locally: Manufactured in our Lower Mainland facility to withstand BC’s specific climate.
- Installed Internally: We never outsource your peace of mind. Our crews are A1 employees, COR-certified, and trained in proper rainscreen detailing.
- Supported Forever: One call handles engineering, manufacturing, and warranty. No chasing third-party vendors.

The Anatomy of a Leak-Proof Entryway
Why do so many “lifetime” doors fail after five winters? Often, it is because water gets trapped inside the frame or behind the flange, leading to rot that you can’t see until it’s too late. The R-301 Series is designed to solve the specific water ingress challenges found in British Columbia homes.
- Hydro-Efficient Design: The 4-5/8 inch all-PVC frame features a brand-new internal slope system that actively directs water away from your interior, preventing the standing water that leads to seal failure.
- “Code-Plus” Installation: We don’t just “fit” the door. We integrate it into your building envelope using BC Housing Best Practices. This includes proper flashing, waterproofing membranes, and retrofit flanges designed to stop rot before it starts.
Flange
Glazing Options
Available in Triple Glazed Patio Doors for maximum noise reduction and thermal performance, or Double Glazed Low-E 366 to block summer heat while retaining winter warmth
Available in high performance double or triple glazed, including the latest in spacer technology
Our standard high-performance Low-E insulating glass lowers energy costs, helps homes stay cooler in the summer and warmer in the winter, reducing the fading of interior furnishings and condensation. It also delivers greater visible light transmittance than tinted glass.
Add architectural interest to your patio door with our divided lite options. These options include simulated divided lites (SDL) for an authentic look. They feature grilles that are permanently attached to the interior between the two panes of insulating glass to provide design detail.
Grilles are available in 5/8″ widths (Georgian or Rectangular) in several grille patterns. These grilles are available in the color that matches the exterior color.
Safety Glass
Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass. Laminated glass is normally used when there is a possibility of human impact or where the glass could fall.
Tempered glass is a type of safety glass that has increased strength and will usually shatter in small, rounded grains instead of jagged shards when broken. It is used when strength, thermal resistance and safety are important considerations. In residential applications it’s mainly found in bathrooms, patio doors and fixed lites adjacent to doors.
Colour Options
Choose from a standard pallet or go for true custom match to suit your style. Our water borne pvc paint is engineered to permanently bond to the frame providing lasting durability and colour fastness.
- Custom Configurations: Available in 2, 3, or 4-panel configurations to fit any opening.
- Aesthetic Options: Combine the traditional aesthetics of a garden door with the rot-resistance of high-grade UPVC. Optional decorative kick panels and multiple grid options allow you to match your home’s architectural style without worrying about peeling paint.
