LEXAN™ THERMOCLEAR™ - Premium multiwall sheeting system
LEXAN™ THERMOCLEAR™ Multiwall polycarbonate sheeting features a two sided proprietary surface treatment designed to protect the sheet against the degrading effects of ultra-violet radiation in natural sunlight. The two sided UV protected surface offers advantages in economical cutting. Installation mistakes are minimised since both sheet surfaces may be faced outwards.
From conservatories, commercial greenhouses and swimming pools, to industrial buildings, offices and sports stadiums, this versatile range of materials helps to deliver state of the art, lightweight glazing for commercial, industrial and residential applications.
Ampelite stock 10mm twinwall sheet which is widely used in small commercial and residential applications where superior stiffness is required. We can supply X-structures in gauges up to 32mm thick based on minimum order quantities.
Ampelite provides a range of glazing accessories to clad your project including:
Aluminium H-Bars, Flexibars and End Caps
Rubber Gaskets to suit
