Twinfix is the UK’s leading manufacturer of aluminium panel glazing systems for use with polycarbonate glazing.

The Company was formed in 1990 and, in an earlier life as Thermoclear UK Ltd, was the first to develop a range of glazing bars and fixing accessories specifically designed for installing multiwall polycarbonate sheet.

We design, manufacture, supply and install a wide range of products and systems which have been widely specified for new-build and refurbishment applications.

As an accredited CHAS contractor and a member of both Constructionline and Link-up, we are committed to Health & Safety and to working in an environmentally responsible manner.

Today’s Twinfix range includes:

  • Patented modular rooflight systems incorporating multiwall polycarbonate sheet integrated into aluminium framed glazing bars – including our well-known Multi-Link Panel NF (non-fragile)
  • Custom designed polycarbonate-glazed shelters, canopies and walkways
  • Fixing systems for rain-screen cladding materials, such as TRESPA sheet
  • Modular polycabonate roof domes and barrel vault rooflights for flat roof applications
  • 40mm thick, ‘click-together’ polycarbonate vertical glazing
