Slider Windows
Horizontal sliding windows that save space and suit modern layouts. No swing—ideal next to patios and in tight spots. Engineered for Canadian and American homes.
Why Choose Slider Windows?
Slider windows open horizontally on a track—no crank, no swing into the room or outward. That makes them ideal next to patios, walkways, and in narrow spaces. Large glass panels and minimal framing give a modern, clean look and maximize views. Open one or both sides for flexible ventilation. Simple operation and low maintenance with no hinges or cranks to wear.

Engineering & Specifications
VDK Ultra Slider Windows are built to the same high standards—fusion-welded corners, multi-chamber frames, and premium uPVC construction for lasting performance and energy efficiency.
Fusion-Welded Corners
Frame corners are heat-fused into a single, seamless piece — not screwed or glued. This creates an airtight, watertight joint that maintains structural integrity for the life of the window.
Multi-Chamber Frame Design
The frame profile contains multiple hollow chambers that trap air, creating a natural thermal barrier. This design significantly reduces heat transfer through the frame itself.
Premium uPVC Construction
Made from high-quality unplasticized PVC that resists fading, warping, cracking, and rot. Unlike wood, it never needs painting or staining. Unlike aluminum, it won't corrode or conduct cold.
Warm Edge Spacer System
Advanced spacer technology between glass panes reduces condensation at the glass edge and improves overall thermal performance, keeping the interior glass surface warmer in winter.

Frequently Asked Questions
Slider windows open horizontally on a track—no crank, no swing into the room or outward. They are ideal next to patios, decks, and walkways where an outward-opening window would be in the way, and in narrow spaces. Large glass and minimal framing give a modern look and flexible ventilation when you open one or both sides.
Yes. VDK Ultra Slider Windows use multi-chamber frames, quality weatherstripping, and optional double or triple pane glass with Low-E coatings and argon fill. They are ENERGY STAR certified and provide solid energy performance and comfort.
Sliders work well along long walls and in rooms with lower ceilings (the horizontal line can make the space feel taller), next to patios and walkouts where outward swing is not desired, in contemporary and modern-style homes, and in corridors or tight spaces where saving room space matters.
