100 % biobased insulation material


Targeting European single or multiple-storey residential, Pavaroof, Univercell, Pavaflex Confort, Pavawall and Isolair are five solutions based on the Pavatex bio-material to insulate buildings.

The Pavatex 100% bio-sourced offer is cellulose fibre-based : wood and cellulose wadding. One originates from woodland timber, coming from products related to sawing or first transformation. The other, cellulose wadding originates from a newspaper recycling process. These solutions allow the insulation of buildings of one or more storeys. The Pavaroof system based on wood fibres is designed for flat roofs. For sloped roofs and vertical walls between wooden framework struts are designed the Univercell product based on cellulose wadding or the Pavaflex Confort product based on wood fibres. Finally regarding the external architectural aspect of the building, SOPREMA proposes an exterior insulation solution based on wood fibres under plaster with the Pavawall system, or behind ventilated cladding with the Isolair system. All these solutions ensure energy savings and comfort for the users.
