Sliding Windows

Vinyl sliding windows open with a smooth, horizontal glide for easy airflow and a clean, modern look. Dual sashes ride on durable tracks, so the window moves without taking up interior or exterior space. Slim frames keep more glass in view, while tight weather seals help limit drafts and reduce outside noise. Pair with Low-E glass and argon for stronger thermal performance. If you’re comparing options for sliding window replacement, vinyl offers low maintenance, stable color, and long service life.

Rated to 200°F – Smooth Slide in Heat

The Onyx Collection offers exceptional heat resistance, performing at temperatures up to 200°F. Standard vinyl is typically rated around 162°F. In hot climates, this helps vinyl windows, especially black vinyl windows, hold shape so sliding sashes move easily and lock cleanly, supporting energy-efficient windows’ performance.

Engineered for Stability in Sliding Frames

Intense heat, direct sun, and moisture can cause frames to expand or shrink. This onyx profile maintains dimensional stability, keeping rails straight so rollers stay aligned and weatherstrips seal along the full perimeter. You get consistent slide action and dependable energy performance for vinyl windows and black vinyl windows in high-sun areas.

Long-Lasting Deep Color + Verified Ratings

The Onyx Collection preserves its deep onyx color under UV exposure, temperature shifts, and changing conditions. Its distinct onyx shade pairs well with many aluminum windows and doors for a clean, contemporary look. The Onyx Collection profile meets ASTM International and AAMA standards. With qualifying glass, the series meets NFRC Energy Star 7.0, the most rigorous U.S. efficiency benchmark, supporting strong thermal performance and long-term comfort.

Frequently Asked Questions

What are sliding windows?

A sliding window has one or more sashes that move side to side on built-in tracks. Think of it as a double hung turned sideways: instead of lifting up and down, the sash glides left or right for ventilation and a clear, modern look.

How long do sliding windows last?

Service life depends on frame material, glass package, and upkeep. Quality vinyl sliding windows commonly deliver up to 40 years of everyday use when well-maintained.

Where do sliding windows work best?

They excel where swing clearance is tight. Next to decks, balconies, and walkways, sliders don’t project outward. Over kitchen counters or sinks, the side-to-side motion is easy to reach. In living rooms, a two- or three-panel gliding window can span wide openings for panoramic views.

What are the advantages of sliding windows?

Sleek look: Slim profiles put the emphasis on glass for a contemporary aesthetic.
Space saving: Sashes move within the frame, ideal near paths and outdoor living areas.
Cost efficient for wide spans: One wide unit can replace multiple joined windows.
Low maintenance: Fewer moving parts and lift-out sashes simplify cleaning.
Flexible ventilation: Open one panel or create a large clear opening when you want maximum airflow.

Are sliding windows energy efficient?

Yes, when built with tight seals, Low-E coated glass, warm-edge spacers, and argon-filled insulating glass. Look for NFRC ratings that match your climate goals for U-factor and SHGC.

Do sliding windows come in different sizes and configurations?

Common layouts include two-panel (one or both sashes operable) and three-panel (center fixed or operable). Custom sizes, grille patterns, and privacy glass options are available to match your home’s style.

GLASS

Creating your own insulating glass unit (IGU) by following three simple steps

Step 1: Type of Glass

Annealed |Tempered | Laminated

Annealed Glass

Clear, standard glass with excellent clarity and value for everyday applications.

Tempered Glass

Heat-treated for additional strength and safety. If broken, it crumbles into small pieces to help reduce injury risk.

Laminated Glass

Two sheets bonded with a safety interlayer. Enhances security, improves sound control, helps block UV, and holds together on impact.

Step 2: Dual-pane / Triple-Pane

Dual-Pane IGU

Two panes separated by a warm-edge spacer with argon gas between the panes. A balanced choice for clear views, insulation, and cost.

Triplepane Glass Diagram with Two LoE 366 Glass

Triple-Pane IGU

Three panes with two spacers and argon gas in both chambers. Higher insulation and better sound control. Available on select sizes.

Step 3: Energy-Efficient Coated Glass

LoE 366

Triple layer coating glass for outside solar control. Helps manage heat gain while keeping interiors bright.

LoE i89

Four layer coating clear glass for room-side efficiency. Enhances insulation and supports maximum energy savings.

Step 4: Color & Pattern Options

Choose from a range of pattern glass designs to add privacy and character to bathrooms, entry areas, and other spaces. These options bring dimension to windows or doors while maintaining natural light.

GRID

Grid Between the Glasses

The grille sits between the panes, so you get the look you want and an easy-to-clean glass surface with no exterior bars to wipe around. *We also offer Simulated Divided Lite (SDL) grids for specific window and door styles. SDL options require additional lead time and cost. Please contact our sales team for details.

Flat Grids Size: 5/8, ¾

Sculptured Grid Size: 5/8, 1

Grid Patterns

Available patterns include Marginal, Double Prairie, Colonial, and Marginal MG18.

*Grid patterns allow wide customization but are limited to vertical and horizontal orientations. *Geometric picture windows have specific grid pattern options. Please contact our sales team for more information.
