Is the Floorify underlay/floor insulating?

Sous-couches Floorify, our underlays do not have an insulating effect. They are designed for use in combination with underfloor heating and therefore have a low heat resistance (R-value). In other words, they allow heat and cold to pass through well.

Hard insulating boards can offer a solution if you want an insulating effect. Here, it is important to choose hard/non-resilient boards.
