Understanding Polycarbonate & The LEXAN™ Distinction
Polycarbonate (PC) is a high-performance thermoplastic polymer engineered for high optical clarity and extreme impact resistance. LEXAN™ is the world-renowned brand name for premium polycarbonate resin products manufactured by SABIC.
Polycarbonate Sheet Systems & Typologies
Tailoring sheet selection based on structural span, aesthetic requirements, and solar heat gain control.
Solid Polycarbonate Sheets
Flat monolithic sheets providing glass-like optical clarity with virtually unbreakable impact strength—ideal for architectural entrance canopies, viewing panels, and clear roof features.
Multiwall Polycarbonate Sheets
Multi-layered cellular structures (Twin-Wall, Triple-Wall) offering internal air channels that deliver thermal insulation, diffuse harsh sunlight, and span wide purlins at low dead weight.
LEXAN™ THERMOCLEAR™ Systems
Advanced multiwall glazing systems featuring proprietary UV surface treatment, Solar Control heat attenuation, and superior resistance to yellowing and weathering over decades.
Cold-Curved Roof Systems
Leveraging material flexibility to cold-curve panels on site within certified minimum bending radii for arched walkways, barrel vaults, and curved skylights.
Key Application Spheres for Polycarbonate & LEXAN™
Thermal Expansion & Fixing Systems
Polycarbonate panels possess a noticeable coefficient of thermal expansion. RAACO employs specialized aluminum glazing profiles with EPDM gaskets that accommodate linear expansion without sheet buckling or joint stress.
Waterproofing & Rainwater Discharge
Eliminating leaks requires proper drainage slopes, anti-dust breather tape sealing on cell ends, integrated collection gutters, and engineered perimeter flashing at wall interfaces.
End-to-End Execution Workflow
* RAACO unifies structural steel fabrication with polycarbonate sheet glazing and aluminum profile fixing for complete system integrity.
