Our Insulated Sliding Windows Are Made For Canadian Weather

Our sliding windows are engineered for Ontario’s extreme weather conditions. With Low-E coated glass, argon gas-filled units, and multi-chambered vinyl frames, they block out cold drafts, reduce heat loss, and cut energy costs. Every unit is CSA-certified and Energy Star® rated, meeting the latest building code requirements across the GTA.

Unlike off-the-shelf options, our windows are custom-built for your home, ensuring airtight installation and lasting performance. If you’re replacing old sliders or upgrading drafty windows, our systems deliver proven insulation, durability, and long-term value.

Sliding Window Styles Tailored to Your Needs

We offer a full range of sliding window styles to suit any home in the GTA. Whether you’re replacing outdated units or planning a new build, our custom-fit options are engineered for performance, durability, and energy efficiency.

Single Slider Windows

Single slider windows feature one fixed sash and one operable sash that glides horizontally. Ideal for smaller rooms, they offer excellent ventilation without taking up extra space. Our units include Low-E glass, argon gas insulation, and multi-point locks for added security. Perfect for basements, bathrooms, and tight wall openings where swing clearance is limited. Every unit is custom-sized and installed airtight for superior comfort and energy savings.

Double Slider Windows

Double slider windows allow both sashes to open, giving you full ventilation from either side. They’re perfect for larger openings where airflow and ease of cleaning matter most. Our units come with removable sashes, fusion-welded corners, and dual-pane or triple-pane glazing for optimal performance. Popular in bedrooms, living rooms, and open-concept spaces, double sliders from Polaris are built to outperform mass-produced alternatives, both in thermal efficiency and long-term durability.

End-Vent Slider Windows

End-vent sliders are ideal for wide openings where casement or double-hung windows won’t fit. With two operable sashes on either side of a fixed centre panel, they offer excellent air circulation and unobstructed views. Our systems include precision-engineered sliding tracks, weather-tight seals, and high-efficiency vinyl frames to withstand Ontario’s climate. A popular upgrade for living rooms and front-facing windows, our end-vent sliders deliver performance and curb appeal,custom-fit to your space.

Sliding Window Installation

Our installation service is designed for new builds and renovations. Every window is custom-measured and fitted with CSA-certified, Energy Star® rated frames, ensuring airtight performance. Using Low-E coated glass and argon-filled chambers, we optimize insulation and long-term efficiency. Unlike generic contractors, we specialize in GTA homes, guaranteeing professional, clean installs that meet local building codes.

If your existing sliders are drafty, fogged, or inefficient, we offer full-frame or retrofit replacements. We remove old units, seal openings with precision, and install multi-chamber vinyl frames for maximum durability. Our fusion-welded corners and dual- or triple-pane glass outperform outdated models. With us, you’ll get faster service, higher efficiency, and a warranty-backed installation that extends your home’s value.

Horizontal Sliding Window Replacement

Horizontal sliding windows are ideal for tight spaces. We replace worn tracks, inefficient glass, or dated frames with advanced precision-engineered rollers and insulated glass systems. These upgrades enhance smooth operation and improve thermal resistance. Homeowners across the GTA trust us for accurate sizing, superior materials, and expert installation, delivering modern functionality where space is limited.

Sliding Window Screen and Track Replacement

Damaged screens or warped tracks compromise performance. We provide custom-fit screen replacements and track upgrades that restore smooth operation and secure ventilation. Using high-strength mesh and reinforced track systems, we extend the lifespan of your sliding windows. Unlike quick-fix options, our replacements are built for durability, ensuring reliable use through Toronto’s harsh climate.

Our Energy Star® certified sliders provide insulation, security, and natural light, perfect for basement walkouts or layout changes. With airtight seals, multi-point locking hardware, and custom sizing, we transform unused door openings into efficient windows that boost comfort and curb appeal across the GTA.

What Makes Our Sliding Windows Stand Out

Our sliding windows are engineered for durability, insulation, and effortless use. Every feature is designed to meet Canadian standards and outperform generic options.

Low-E Coated, Energy Star Glass

We use Energy Star® certified, Low-E coated glass to reflect UV rays, reduce solar heat gain, and keep your home comfortable in all seasons. This advanced technology lowers energy bills and prevents fading of furniture. Unlike basic glass, our coatings are engineered for GTA climate performance.

Double or Triple Glazed Panes

Choose from dual-pane or triple-pane glazing for superior insulation. Our multi-layer construction minimizes heat loss, improves energy efficiency, and adds strength to your windows. Triple glazing is ideal for noisy neighbourhoods and colder areas of the GTA, offering unmatched comfort and quiet.

Argon Gas-Filled Chambers

Our insulated glass units are filled with argon gas, a non-toxic, odourless insulator that slows heat transfer. This boosts thermal efficiency without compromising clarity. Combined with Low-E coatings, argon gas ensures your windows outperform builder-grade alternatives year-round.

Multi-Chamber Vinyl Frames

We use fusion-welded, multi-chamber vinyl frames that increase rigidity, block thermal transfer, and resist warping or cracking. These frames provide durability and airtight seals. Compared to aluminum or wood, vinyl frames offer longer-lasting performance with zero maintenance.

Precision-Engineered Sliding Tracks & Rollers

Our windows glide effortlessly thanks to precision-engineered tracks and rollers. Designed for smooth operation, they resist jamming, sticking, and wear over time. We use reinforced materials that withstand repeated use, making our sliders more reliable than low-cost builder models.

Multi-Point Locking for Enhanced Security

Each window is equipped with multi-point locking systems that secure the sash at several points along the frame. This prevents forced entry and creates a tighter weather seal. Our security hardware outperforms standard latch systems, keeping GTA families safer and more comfortable.

Sound Reduction Design

Our sliding windows include insulated glass and weather-tight seals to reduce noise from busy streets, highways, or neighbours. Whether you live downtown Toronto or near a high-traffic area, our windows deliver a quieter, more peaceful home environment.

Custom Colours, Trims & Grilles

We offer complete customization with colours, trims, brickmoulds, and grille patterns that match your home’s design. From modern black frames to traditional white finishes, our options elevate curb appeal. Every unit is made-to-order for a seamless fit and lasting style.

The Lasting Benefits of Sliding Windows

Our sliding windows are more than a style upgrade; they’re engineered to deliver efficiency, comfort, and durability that homeowners across the GTA rely on. Here are all the benefits of sliding windows:

Built with Low-E coated glass, argon-filled chambers, and multi-chamber vinyl frames, our windows minimize heat transfer. This lowers utility bills, improves insulation, and provides year-round comfort. We outperform builder-grade units with Energy Star® certified performance.

Sliding windows open wider than most other styles, allowing for maximum air circulation. Precision rollers ensure smooth gliding, so you can easily adjust ventilation. Perfect for kitchens, basements, or living rooms where airflow is essential.

With wide glass panes and slim frames, our sliders let in more daylight, brightening interiors and reducing reliance on artificial lighting. This not only enhances comfort but also improves indoor aesthetics, ideal for smaller GTA homes or condos.

Sliding windows move horizontally within the frame, requiring no extra clearance. They’re a smart choice for tight spaces like walkways, patios, or basements. Unlike casement windows, sliders maximize usability without limiting your room layout.

Our precision-engineered tracks and rollers make opening and closing effortless. No sticking, no jamming, just reliable performance for decades. Homeowners trust our sliders to deliver consistent ease of use, even in high-traffic rooms.

Crafted from vinyl frames that don’t warp, rot, or peel, our windows are designed for long-term performance with minimal upkeep. Lift-out sashes make cleaning simple, inside and out. Compared to wood or aluminum, our systems require less work and last longer.

With double or triple-glazed glass and weather-tight seals, our sliders reduce outside noise from traffic or busy neighbourhoods. This creates a quieter, more peaceful environment, especially for homes in urban GTA areas.

Equipped with multi-point locking systems and reinforced frames, our sliding windows provide enhanced protection against forced entry. Stronger seals also improve insulation, combining safety with energy efficiency.

Upgrading to modern, energy-efficient sliders enhances curb appeal and resale value. Buyers in the GTA recognize the value of CSA-certified, Energy Star® windows, making your investment pay off in comfort and future returns.
