Installation with protective fleece (optional)

To prevent damage to the radon foil, the AlphaBlock 3 is laid between two layers of tear- and drill-resistant protective fleece.

The protective fleece is laid over the entire surface under the radon foil. The sheets can either be laid tightly butted or with an overlap. It is not absolutely necessary to glue the sheets together, but it is possible.

One roll of protective fleece with 100 m² is sufficient to lay one roll of AlphaBlock 3 using the sandwich method (protective fleece - AlphaBlock 3 - protective fleece).
