The Product
The GEO=FAST SDL Grid System
Simulated Divided Lite (SDL) grids replicate the classic appearance of true divided lite windows at a fraction of the cost. GeoFast's precision-engineered profiles snap directly onto our patented clips, creating a seamless, authentic grid pattern that satisfies the most demanding architectural specifications.
Designed for window and door manufacturers, contractors, and architects who refuse to compromise on quality or schedule.
Features
Engineered for the demands of modern production
Easy Snap Installation
Engineered snap-fit profiles lock onto glass without reliance on only adhesives due to the patented clips and minimal tools depending on window or door system. What used to take hours now takes minutes — without sacrificing precision.
Precision Engineered
Every profile is manufactured to exacting tolerances, ensuring the users can have aligned grid intersections across the entire window or door unit.
Durable & Weather-Resistant
Formulated to withstand UV exposure, thermal cycling, and moisture. GeoFast grids maintain their finish and structural integrity long term.
How It Works
Three steps to a finished grid
Measure & Cut
Cut GeoFast profiles to the required dimensions using standard shop tools or easy to use end milling machines.
Snap Into Place
Press profiles onto the clips attached around the sealed unit or on the glass surface. The patented snap-fit system locks each piece securely.
Inspect & Ship
Verify alignment, trim any excess, and the unit is ready. Clean lines, zero rework — straight to the job site.
"Invented for the people who build America's windows."
