What Are
Slider Windows?
Slider windows, also known as horizontal sliding windows, open by gliding one sash horizontally past the other. Unlike casement or awning windows that swing outward, slider windows stay flush with the wall—making them ideal for tight spaces, walkways, or areas with limited exterior clearance.
They’re perfect for:
- Basements– Where outward-opening windows aren’t practical
- Bedrooms – Especially for egress compliance
- Living rooms – For wide, unobstructed views
- Kitchens – Where ventilation and ease of use are key
- Hallways or stairwells – Where space is limited
Features & Benefits of Our Slider Windows
Designed for Ventilation. Engineered for Alberta.
At ASAP Windows & Doors, our slider windows are more than just a stylish addition to your home—they’re a smart investment in comfort, energy efficiency, and long-term performance. Manufactured locally in Calgary, our awning windows are built to handle Alberta’s demanding climate while offering homeowners a sleek, functional, and secure solution for everyday living.
Whether you’re upgrading a bathroom, finishing a basement, or designing a new build, our awning windows are tailored to meet your needs with precision and care.
Effortless to Open. Built to Last
Our slider windows feature precision-engineered tracks and rollers that allow the sash to glide smoothly and quietly. Whether you’re opening them daily or occasionally, the operation remains light and reliable.
Easy Cleaning. Hassle-Free Maintenance.
Both sashes can be tilted or lifted out for cleaning from inside your home—no ladders or exterior access required. This makes slider windows a favorite for upper floors and hard-to-reach areas.
Peace of Mind. Built-In.
Our slider windows come with integrated locking mechanisms that secure the sash in place when closed. Optional ventilation locks allow you to keep the window slightly open while maintaining security.
Durable. Reliable. Weather-Resistant.
We use corrosion-resistant rollers, tracks, and locking components that are built to withstand Alberta’s temperature swings and seasonal moisture.
Timeless Style. Easy Maintenance.
Add character to your slider windows with grilles sealed between the glass panes. Choose from:
- Colonial
- Prairie
- Double Ladder
- Custom Designs
These grilles enhance your home’s look without affecting visibility or cleaning.
Smart Glass for Every Season.
Our slider windows are available with Low-E coatings that reflect heat back into your home in winter and block solar heat in summer. Choose from:
- Sun-Gate 400 – Ideal for passive solar gain in colder climates
- Solarban-60– Balanced performance for year-round comfort
- Solarban-70– Maximum solar control and UV protection
These coatings help reduce energy bills and protect your interior from fading.
Insulation That Works.
Choose the right level of thermal and sound insulation for your space:
- Double-pane: Ideal for standard energy efficiency
- Triple-pane: Best for maximum insulation and noise reduction
All sealed units include warm-edge spacers and argon gas fills for optimal performance.
Invisible Insulation. Real Results.
We fill our insulated glass units with argon gas to reduce heat transfer and improve energy efficiency. These gases are safe, long-lasting, and enhance your window’s thermal performance.
Tailored to Fit. Built to Perform.
Every slider window is custom-manufactured to your exact specifications. Whether you need a wide panoramic unit or a compact basement window, we’ll build it to fit your space and style.
Our slider windows are:
- ENERGY STAR® Certified
- NAFS-11 Tested
- CSA A440 Compliant
These certifications ensure your windows meet or exceed Canadian standards for air, water, and structural performance—giving you peace of mind and long-term value.
Where to Use Slider Windows
Slider windows are incredibly versatile and can be installed in nearly any room of the house. Their compact design and weather-resistant functionality make them ideal for:
Bathroom
For privacy, moisture control, and fresh air.
Kitchens
Above countertops or sinks where space is limited.
Basements
As a secure, weather-resistant option for non-egress openings.
Bedrooms
Paired with fixed windows for added ventilation and style.
Living Areas
Combined with picture windows for panoramic views and airflow.
They’re also a great choice for multi-window configurations, such as stacked or side-by-side installations.

- Airtight Seals – Prevent drafts and moisture infiltration.
- Insulated Frames – Reduce heat loss and improve energy efficiency.
- ENERGY STAR® Certified Glass – Keeps your home comfortable year-round.
- Durable Hardware – Resists corrosion and wear, even in harsh conditions.
Whether you’re facing a snowstorm or a summer thunderstorm, our awning windows are designed to perform.
