The sheet system's joint is made of aluminum, solving the problem of thermal expansion or contraction along length direction. One complete sheet system includes a full set of accessories and installation guide, reaching effects of easy-installation and simple maintenance. water-proof capability. The sheet system also has all kinds of features of polycarbonate solid sheet.
In hot season ,surface temperature of sheet may reach to +50℃ .The U value represents the thermal transmittance level of daylighting materials.(higher U value,lower thermal insula
tion,more energy loss).The following form compared U value of glass with polycarbonate solid sheet with same thickness (thicker sheets ,better thermal insulation,lower U value,less
thermal loss).Any thickness of polycarbonate sheets has a lower U value than glass ,In other words,the thermal loss inside and thermal transmission from outside of the architectures with U-lock polycarbonate solid system will be lower than with glass materials.That means it could save about 6.5-9% energy consumption which embodied in winter heating and summer cooling. Notice:sunlight control sheets could low solar energy transmission and this will reduce the cost of summer air-condition .
PC sheet is able to maintain its mechanical property and transparency due to its co-extruded UV layer, which would not exfoliate over time. Figures attached to shows that sheet’s light transmission keep stable after the sheets are exposed to weather equal to 20 years under the speeded weathering.
隔音性能
Sound Insulated
U 型实心板板具有相当优良的隔音性能，详情见附 表。优良的隔音性能加上其抗冲击性，使得U型实心板成为覆层的理想选择。
U-type solid sheet is well sound insulated(see attachment). Because of its well is well sound insulation and impact resistance, U-type solid sheet is a ideal choice for cladding.
