Built to hold up on wind-exposed jobs, not just look good on day one
Every spec here exists to answer the question a contractor asks the moment they see the price: what's wrong with it. Nothing.
UPVC Vinyl Material
Won't rot, warp, or corrode — eliminates the callback wood and aluminum frames eventually generate.
Vinyl Mainframe and Sashes
Full-vinyl construction throughout the frame and sash, not just at the visible surface.
Multi-Chambered Frames
Multiple internal chambers add structural rigidity and thermal separation in a single extrusion.
Continuous Fusion-Welded Frame
Corners are fused, not mechanically fastened — they don't separate over time.
Nailing Fin Welded at All Corners
Fully welded nailing fin means a watertight installation without extra flashing work.
Double Insulated Glass
Two panes with a sealed air space — fewer draft complaints from the homeowner after handoff.
Double Weatherstripping
Seals twice where most windows seal once — where the performance gain actually comes from.
Interlock at Sash Locking Rail
Sashes interlock at the rail rather than just meeting, closing the gap that lets air and water through.
Metal Reinforcement at Locking Rail
Adds structural strength exactly where wind load stresses the frame most.
SweepStyle Cam Lock
Draws the sash tight on close, producing a tighter seal than a standard latch.
Integral Pull Handle
Built into the sash — no hardware that loosens or breaks off over time.
Removable Fiberglass Screens
The homeowner pops them out and cleans them. You don't get the call.
Clean-Line Design
A slimmer sightline profile that opens up a larger viewing area.
Made in U.S.A.
Manufactured domestically — no port delays stacked onto your lead time.
Two-Lite Horizontal Sliding Window
Built for volume installs. Smooth horizontal glide, clean-line sightlines, and every spec on this page built in as standard — not an upgrade tier.
