PVC FREE FOAM VS. CELUKA TECHNOLOGY
Jun 15, 2018


“Free Foam” and “Celuka” are the two predominant types of PVC manufacturing technologies. Both have been available for some time, but Palram favours the Free Foam method as it produces a more consistent density throughout the panel.

The cellular structure of the panel’s core is dense and, if manufactured to Palram’s high standards, does not contain voids or large air bubbles. Celuka PVC typically has a less dense core structure but has a harder “skin” on the outer surface which can sometimes result in chipping when cut.

The image shown here has been highlighted with blue to illustrate the typical thickness of the harder skin.

If you look at the edge of the Celuka product, you’ll see chipping has occurred. Fabrication and milling of Free Foam PVC are generally easier and results in a better finish than Celuka products
