Lexan Thermoclear 16/6RS has a two sides proprietary UV protected surface, giving superior resistance to outdoor weathering. Lexan Thermoclear 16/6RS is available in two commercial grades, namely LT2UV166RS27 (2.7 kg/m 2 ) and (2.9 kg/m 2 ). 16 W 20 Typical Property Values Property Test method Unit Value Physical Specific gravity ISO Weight kg/m / 2.9 Gauge mm 16 Sheet width (W) mm 980 / 1250 / 1600 / 2100 Rib distance mm 20 Hail impact TNO test Ф 20 mm; v = > 21 m/s Optical Refractive index ISO Light transmission (LT)# EN 410 Clear (112) % 61 White (WH7A092X) % 52 Bronze (515055) % 29 Metallic (GY6A744M) % 20 Direct solar transmission (DST)# EN 410 Clear (112) % 57 White (WH7A092X) % 49 Bronze (515055) % 33 Metallic (GY6A744M) % 19 Total solar transmission (TST)# EN 410 Clear (112) % 64 White (WH7A092X) % 60 Bronze (515055) % 53 Metallic (GY6A744M) % 32 Solar heat gain coefficient (SHGC)# EN 410 Clear (112) % 0.64 White (WH7A092X) % 0.60 Bronze (515055) % 0.53 Metallic (GY6A744M) % 0.31 Shading coefficient (SC)# EN 410 Clear (112) % 0.73 White (WH7A092X) % 0.69 Bronze (515055) % 0.61 Metallic (GY6A744M) % 0.36 Thermal Coeff. of linear thermal expansion DIN mm/mm ºC U-value DIN W/m 2 K These typical values are not intended for specification purposes.

2 Light / Solar Transmission properties Lexan* Thermoclear* 16/6RS sheet is essential opaque to all wavelengths below 385 nanometers. This useful shielding property can prevent discoloration of sensitive materials placed under or behind. Solar heat gain within a building is caused by heat input from radiation emitted from the sun. Sunlight entering the building heats the air both directly and through absorption by the framework, furniture, etc. and is released as infrared energy. In combination with the insulation properties of Lexan Thermoclear Plus sheet, this prevents heat escaping faster than it is created causing a temperature increase, the so-called greenhouse effect. The temperature can be controlled by venting, often in combination with special tinted opal white or Lexan Thermoclear SC IR which contains a proprietary additive which selectively absorbs the near infrared region of the light. Lexan thermoclear is therefore available in many different colors or with IR additives, which both cuts down the brightness of sunlight to a pleasing level and reduces heat build up inside the building. Calculations for solar heat input through glazing are normally based on data published in The Institution of Heating and Ventilating Engineers Guide Book. These calculations are based on clear glass and correction factors or shading coefficients are then applied when alternative glazing materials are used. Light transmission (LT): Percentage of the incident visible light that passes through an object. Direct solar Transmission (DST): Percentage of incident solar radiation that passes directly through an object. Total solar transmission (TST): The percentage of incident Solar radiation transmitted by an object which includes the direct Solar Transmission plus the part of the Solar Absorption reradiated inward. Solar heat gain coefficient (SHGC) or g-value: The total solar energy that enters the interior of a building, divided by 100. Shading coefficient ( SC): The ratio of the total solar radiation transmitted by a given material to that transmitted by normal 3 mm glass, whose light transmission is 87%. SC=%TST/87. Thermal Insulation The multi-wall structure of Lexan Thermoclear Plus 16 mm 7 wall sheet offers significant advantages where thermal insulation is a major consideration. The hollow form provides excellent insulation characteristics with heat losses significantly lower than mono-wall glazing materials. U- or K-value: W/m2 K. UV-Resistance The complete Lexan Thermoclear Plus sheet range features a proprietary both sides surface treatment designed to protect the sheet against the degrading effects of ultra-violet radiation in natural sunlight. Both sides UV protected surfaces offers advantage in economically cutting the sheet in desired shapes, and installation mistakes are minimized since both sheet surfaces may be faced outwards. Impact Strength Lexan Thermoclear Plus 16 mm 7 wall sheet has outstanding impact performance over a wide temperature range, -40 C to +120 C, and also after prolonged outdoor exposure. As a roof glazing material Lexan Thermoclear Plus 16 mm 7 wall sheet is subjected to the extremes of weather; storms, hail stones, wind, snowfalls and ice formation. Under these conditions, the product is virtually unbreakable and is able to accommodate the subsequent temperature change to sunny conditions without breaking or buckling. Please refer to the warranty for details. Fire Test Performance Lexan Thermoclear Plus 16 mm 7 wall has good fire performance against many national fire codes dependent on thickness and color; please check with the local sales office for details. Warranty offers a Ten Year Limited Warranty written on Lexan Thermoclear Plus sheet covering discoloration, loss of light transmission and loss of strength due weathering. See warranty for exact details. Non-standard Specification All multi-wall sheet can be supplied by prior arrangement in non-standard widths, lengths, and colors. Such arrangements may affect prices, warranty terms and/or other conditions of sale.

3 Deflection characteristics of Lexan* Thermoclear* 16/6RS sheet Four sides clamped: The deflection characteristics in this particular configuration are dependent upon the ratio of the support bar spacing W / L. In practice, W represents the centre-to-centre distance of glazing profiles on the width of the sheet. L represents the centre-to-centre distance of glazing profiles on the length of the sheet. W/L Ratio Max. allowable sheet width in mm (W) 1 : : : > Loading in N/m

4 Two sides clamped, glazing bars parallel with rib structure: W = centre to centre distance of glazing profiles; L = sheet length The major factor determining the sheet deflection behavior is the distance W between the centre points of two adjacent supports. Since any length can be selected, the measurement L does not influence the overall deflection performance. Loading in N/m2 Max. allowable sheet width in mm (W) Two sides clamped, glazing bars perpendicular to rib structure: In this situation, the major factor influencing deflection behavior is the purlin spacing. The sheet width has no influence on the deflection behavior of the sheet when exposed to loading. This means that any sheet width up to the maximum standard width can be selected. Loading in N/m2 Max. allowable sheet width in mm

5 Four sides clamped; cold curved: In this situation sheets are cold curved and clamped at four sides in wet or dry glazing profiles. Here the cold-bending radius must be parallel to the ribs of the sheets. The ratio sheet width (W) / sheet span = 1 : >2. In practice, W represents the centre-to-centre distance of glazing profiles on the width of the sheet. Sheet span represents the centre-to-centre distance of glazing profiles on the length of the sheet.
