Engineered specifically for the North American residential market, this PVC crank casement window series combines traditional American installation methods with modern energy performance. Featuring an integral nail fin for straightforward new‑construction or replacement applications, the system is fully certified to NFRC and CSA standards. The precision crank mechanism delivers smooth, positive operation, while interior‑mounted screens and weather‑adaptive brush seals ensure long‑term cleanliness and draft‑free comfort. Available in single, double, fixed, and splicing configurations, it offers builders and homeowners a versatile, code‑compliant window solution.
1. Authentic Crank Operation – Smooth, Positive Control
Equipped with a heavy‑duty ergonomic crank handle, stainless steel hinge arms, and a multi‑point sash lock, the opening mechanism is engineered for effortless, one‑hand operation throughout the life of the window. The crank system creates a tight compression seal when closed, eliminating drafts, reducing energy loss, and ensuring superior weathertightness.
2. Nail Fin – True North American Installation
A continuous integral nail fin (mounting flange) is factory‑applied around the full perimeter, allowing quick, weather‑tight installation in standard framed openings. Compatible with both new construction and replacement projects, the nail fin ensures compliance with local building codes, simplifies flashing details, and provides a clean, professional finish.
3. Interior‑Mounted Screens – Cleaner, Smarter, Longer Lasting
Unlike traditional exterior screens that collect dirt, pollen, and debris, the screen is positioned on the interior side of the sash. This innovative design:
Protects the screen from rain, snow, UV exposure, and wind‑driven debris
Prevents interference with window operation
Keeps the screen visibly cleaner for extended periods
Allows easy removal for cleaning entirely from inside the home
Eliminates the need for exterior ladders or scaffolding
4. Brush Seal Technology – Smooth Glide, Superior Seal
Advanced pile brush seals are fitted to the outdoor side of the sash. Unlike conventional rubber bulb seals that can create friction, sticking, and premature wear, brush seals:
Significantly reduce operating resistance
Maintain consistent compression over decades of use
Provide effective air, dust, and insect infiltration control
Deliver a noticeably smoother, quieter open/close feel
Perform reliably in extreme temperature variations
5. Certified Energy Performance – NFRC & CSA Verified
This window series has undergone rigorous independent testing and is NFRC certified and CSA A440 compliant. Whole‑window U‑factors, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT) are verified, documented, and labelled in accordance with North American rating protocols. Fully eligible for ENERGY STAR® programs across all US and Canadian climate zones.
6. Versatile Glazing Options – Double & Triple IGUs
Designed to accommodate a wide range of high‑performance insulating glass units:
Double glazing: 3.2 mm glass + 16A / 19A argon gas fill
Triple glazing: 3.2+15A+3.2+13A+3.2 or 3.2+13A+3.2+13A+3.2 configurations
Warm edge stainless steel spacers
Low‑e coatings (soft coat, multiple performance tiers)
Argon/krypton gas fills available
All configurations are factory‑sealed, IGCC‑compliant, and backed by comprehensive warranty.
7. Multi‑Configuration Flexibility – One System, Endless Possibilities
The same extruded main profile accommodates multiple venting and fixed styles:
Single casement – Width ≤ 800 mm / Height ≤ 1600 mm
Double casement – Width ≤ 1600 mm / Height ≤ 1500 mm
Casement & fixed combination
Splicing windows – Horizontal or vertical mulling for large custom openings
Fixed picture windows – Width ≤ 1500 mm (unlimited mulled combinations)
All configurations share common extrusions, hardware platforms, glazing stops, and accessory components – simplifying fabrication, inventory, and field service.
8. Durable PVC Construction – Built for North American Climates
High‑impact UV‑stabilized PVC (vinyl) profiles resist fading, chalking, warping, and corrosion. Multi‑chambered internal geometry enhances thermal performance and structural rigidity. All corners are fusion‑welded, providing superior strength and permanent airtightness. White and custom colour options available with co‑extruded or painted finishes.

For Builders & Remodelers
The integral nail fin means no special adapters, sub‑frames, or complex flashing kits are required – it nails directly into the rough opening, just like traditional American window systems. Consistent sizing, standardized rough opening dimensions, and simplified mulling options streamline installation across entire subdivisions or multifamily projects. One product family serves both new construction and replacement markets.
For Homeowners
Experience draft‑free comfort year‑round with a positive‑sealing crank window that significantly outperforms slider, single‑hung, or double‑hung alternatives in airtightness. Interior screens stay visibly cleaner month after month and are easily removed for washing without leaving the house. The brush seal technology eliminates the “sticky” or “jerky” feel common with aging rubber gaskets. Quiet, smooth, and built to last.
For Architects & Specifiers
Achieve NFRC‑verified energy ratings and CSA compliance with a single, unified product family. The clean, classic sightlines complement both traditional heritage homes and contemporary new builds. Splicing and mulling capabilities allow for grand‑scale custom window walls while maintaining uniform appearance and certified performance. Third‑party verified ratings provide confidence in code compliance and ENERGY STAR® qualification.
