The Floer Rigid Click Vinyl features a stable, low-impact core composed of vinyl and stone minerals, also known as ‘Rigid Core’. Vinyl, like wood and laminate, naturally exhibits movement under different conditions. Rigid Click Vinyl products are thicker than Dryback Vinyl products and therefore more sensitive to this effect. However, adding stone minerals to the core of the Rigid Click Vinyl planks makes the floor less sensitive to impact.
