Polycarbonate Multiwall Sheet

Multiwall polycarbonate sheets are highly engineered and versatile glazing materials, suitable for a wide range of roofing and architectural applications. Their excellent weight-to-performance ratio ensures strong structural performance at economical value.


Supplied by Alakh Industries, these sheets feature dual-side UV co-extruded protection for effective resistance against harmful ultraviolet radiation. The hollow structure, combined with flexibility and superior impact resistance, makes them ideal for diverse glazing and daylighting requirements.


Multiwall polycarbonate sheets offer high installation flexibility, controlled light transmission, thermal insulation, and enhanced aesthetic appeal. A wide range of color options further enhances their visual impact once installed.


By allowing natural daylight while blocking harmful UV rays, these sheets help reduce dependence on artificial lighting and promote safer, more comfortable indoor environments. UV-filtered daylight is widely recognized for improving comfort, productivity, and overall well-being.


More than just a roofing or glazing solution, multiwall polycarbonate sheets represent a smarter approach to daylighting—delivering durability, efficiency, and long-term value.
