Phthalates are plasticisers. This group of chemicals are colourless, odourless viscous liquids. By adding a plasticiser to our LVT floors, the panels become more flexible, making it easier to lay the floor. The phthalates move through the space like condensation. When these phthalates become airborne, they can be harmful to your health. That's why we chose to keep Therdex floors free of phthalates, and use organic plasticisers.
