Twinfix is a family owned and managed business, established in 1990. Described by some as the ‘Pioneers of Polycarbonate’ we, in the main, offer polycarbonate glazing solutions.

From the early years of installing multiwall and solid polycarbonate using our comprehensive range of structural and rafter gasket glazing bar systems, our product portfolio evolved and now includes our ever popular modular polycarbonate roof panel system, the Multi-Link-Panel NF.

These panels are commonly used to form the roof of our canopies, walkways and shelters as well as overhead glazing in roof lights.

Consisting of a lightweight and durable powder coated aluminium frame glazed with polycarbonate, this fix-and-link system is incredibly quick to install. It also features an innovative reinforcing technique that allows the glazed panels to pass the HSE test procedure for Non Fragile Roofing Assemblies (ACR[M]001:2019) as detailed in HSG33.

Whilst polycarbonate will always be our passion, we also have glazing bar systems that are suitable for use with glass as well as our stylish glass canopies with spider bolt connections.

We pride ourselves on having a product to suit most buildings that require either an outside glazed area or glazed roof.

Our offering includes:

  • Aluminium, steel and timber frame canopies, shelters and walkways
  • Glass canopies with spider bolt connections
  • Polycarbonate and glass rooflights
  • Northlight replacement
  • Vertical polycarbonate glazing systems
  • Roller shutters
  • Aluminium rainwater guttering


Many commercial companies will find that one of our products has a natural fit in or on their building, for example:

  • Entrance canopies, glazed covers and walkways
  • Smoking / motorcycle / bike shelters
  • Vandal-resistant glazing
  • Multi-Click vertical privacy glazing
  • Roof domes and pyramids
  • Non-Fragile polycarbonate glazed panels for rooflights
  • Pressed and fabricated aluminium rainwater and flashings

Most of our products are manufactured from aluminium and are usually glazed with either solid or multiwall polycarbonate. These are low maintenance products that are designed to last and that may be recycled at the end of their long life span.

Aluminium loses none of its properties when recycled and many on our aluminium bars and profiles contain recycled product. Powder coated aluminium not only looks good when it is installed, but it will continue to look good throughout its life as it won’t rust in use or require future repainting.

Polycarbonate glazing is an incredible product that doesn’t crack, craze or break during general use, so is an excellent light-weight replacement for glass.
