Vicky Evans is Managing Director at Twinfix Limited 
.
Twinfix was established as a family business in 1990 growing out of Thermoclear UK, the original importers into the UK of Lexan Thermoclear multiwall polycarbonate sheet, generally used for roof glazing applications. The firm also offered custom-designed glazing bars and complementary fixing accessories.
Over the years Twinfix has evolved and whilst still offering polycarbonate glazing, structural and rafter gasket glazing bar systems, continues to innovate and now have many more items in their product basket, such as canopies and walkways.
