Product Data Sheet
LexanŽ ThermonclearŽ Sheet LTC10/2RS1700
LTC10/2RS1700 is a member of the LexanŽ ThermoclearŽ sheet range of high quality, multi-wall polycarbonate glazing sheets extruded from LexanŽ resin.
twin wall rectangular structure
recommended for curved applications
high impact strength
excellent light transmission
light weight, easy installation
long term weather resistance
The complete Lexan Thermoclear sheet range features a propriety one-side surface treatment designed to protect the sheet against degrading effects of ultra-violet radiation in natural sunlight. This side must always be installed facing outwards.
Lexan Thermoclear Dripgard Sheet
Lexan Thermoclear Dripgard sheet features an additional proprietary surface treatment, on the inward facing side, to inhibit the formation of condensation water droplets. This property is particularly important in helping to prevent plant spoilage in greenhouse. Lexan Thermoclear Dripgard can be ordered using the following code LTD10/2RS1700.
GE Plastics offers a Ten Year Limited Warranty on Lexan Thermoclear sheet covering discoloration, loss of light transmission and loss of strength due to weathering. See warranty for exact details. Non-Standard Specifications All GE Plastics multi-wall sheet products can be supplied by prior arrangement in non-standard widths, lengths and colours. Such arrangements may affect prices, warranty terms and/or other conditions of sale.
Installation Design Parameters shown here are typical values measured and calculated according to Building and Construction Research Report no. B-90-480, from the Netherlands Organisation for Applied Science Research (TNO).
