Made up of 90% natural raw materials, this Clever Click Underlay is completely recyclable, and boasts excellent thermal conductivity, making it perfect for underfloor heating or cooling. It also smooths out small subfloor irregularities, and is lightly tackified, which prevents movement and allows easier installation of your vinyl floor. Its protective film captures dust particles too, so that you can easily install this underlay even while other work is being carried on in the same room!
