What Are The Different Polycarbonate Options For Architecture?

Monday, July 26th, 2021

If you are thinking about polycarbonate as a roofing option for your renovation or new build, then you are onto a winning solution. Polycarbonate is not only an eco-friendly product with a low carbon footprint product and good insulation qualities, but you can use it very effectively for light diffusion or, the opposite, light filtering. Compared to an option such as glass, it is far more budget-friendly, much easier to handle on-site, has superior impact resistance and comes with diverse aesthetics options. 

Its most significant advantage over glass is its insulation properties, specifically twinwall polycarbonate, making it popular globally.

Natural Light Benefits

Polycarbonate meets market needs with different colour finishes and new, advanced UV resistance, extending its already impressive longevity. In addition, you can find vertical wall, window, and modular roof panels. You can choose high-transparency panels to allow more natural light into the interior or select an option to increase thermal insulation for passive heating.

Versatility Benefits

From greenhouses to room dividers to roofs and fences, you can use polycarbonate as a hurricane window protection solution or an aesthetic cladding to the exterior of your new, award-winning building. Polycarbonate’s ability to bend makes it a keen favourite of architects, but building owners should remember that the thicker the sheet is, the less it can bend. 

Polycarbonate Specifications

Polycarbonate is created via an extrusion process of fused thermoplastic polymers. The different extrusions create solid, corrugated or multiwall (structured) sheets. 

  • The solid sheets are as transparent as glass
  • The corrugated extrusions create the classic wave sheets 
  • The twinwall extrusion creates a dual wall product with an internal structure of hollow flutes.

Twinwall Polycarbonate

Twinwall polycarbonate profiles can be extruded in different wall configurations. The most popular options are the standard cross-section and the X-structure. The thermal insulation coefficient is subject to the thickness of each outer wall plus the volume of air pockets or flutes.

Extrusions can be infinite in theory, and therefore there is no ‘market standard size’ but manufacturers’ sizes which are determined by their machinery. The resulting product thickness is between 4 mm and 40 mm.


The different colourways deliver different light transmission and aesthetic outcomes. For example, the bronze and opal options are popular for managing solar heat gain, whereas the clear, “orange peel” finish and opal are used for degrees of light diffusion. 

The polycarbonate roofing sheets are used for their linear aesthetic and can be installed with their linear pattern perpendicular to the main building’s lines, creating a striking contrast of planes.

Whatever your project needs, there is a polycarbonate option to solve it. The only limit? Your imagination!
