Spanizol DL is a reflective increased-strength water-vapour seal

Spanizol DL material is made of woven polypropylene fabric doubled with metallized polypropylene film.

A complex material has the property of reflecting thermal radiation and, in addition, performs the functions of water-vapour seal, i.e. protection of the insulant and internal elements of roof and walls against the vapours from inside the room. Spanizol DL material allows to save on room heating.

Spanizol DL is used as a vapour seal in order to protect the insulant and other building components against the saturation of water vapours from inside the room in the structures of inter-floor coverings, roofs and walls. The material can be used as a substrate layer for any floor coatings and “heat-insulated floor” system in order to directly reflect heat into the room.

It can be used as a screen reflecting the heat flux from the heating system, which reduces the heat loss.
