Taking advantage of the honeycomb structure, the new developed Lixin 4-wall H-structure sheet provides higher impact resistance at less weight than traditional sheet while maintaining high light transmission. The built-in hexagonal honeycomb structure can efficiently improve soundproof and heat insulation of the sheet. It eliminates the chance for water leakage. All Lixin sheets are supplied with 10 years warranty. Available in 8mm, 10mm and 12mm thicknesses.
