Purpose and goal
The goal of the project has been to study the production of foam-formed 100 % cellulose based insulation materials in order to replace oil based products. Two products have been considered; insulation panels and insulation foams. An evaluation of the environmental impact as well as market opportunities was also part of the project. The project has shown that it is possible to foam form insulation panels form paper based pulps with insulation properties comparable to commercial products. Production is indicated to both be environmentally more friendly and commercially of interest.
Expected results and effects
The project shows great potential for using wood fibres as an environmental friendly insulation material. Insulation panels with good thermal insulation and acceptable mechanical and fire resistant properties have been produced form cellulosic pulps using foam forming techniques. These panels are suitable for insulation of walls and roofs of ordinary buildings. The production has clear environmental advantages and a production adjacent to a pulp mill could be economically of interest. Technique for producing cellulose spray-on insulation foam has also been put forward.
Planned approach and implementation
The project has involved partners from different European countries, from academia to industrial pulp and insulation panel producers. In the project different partners has produced pulps from both soft- and hardwood and panels have been formed using foam technology. The insulation boards have been tested for thermal conductivity, mechanical properties and fire and mould resistance. The activities have been coordinated by a project board and the results transmitted in regular meetings and public workshops.
