matisse insulation

This report addresses the potential of utilizing biobased insulation materials as a substitute for insulation in the cavity of new built residential buildings. Due to the sustainability ambitions of both parties, the question arose how to insulate the residential building more sustainably. Biobased products are wholly or partly derived from materials of biological origin, excluding materials embedded in geological formations and/or fossilised". The reason for using biobased materials lays in their potential to make economy more sustainable and to lower the dependence on fossil fuels. Métisse is a biobased material. The current market offers little biobased insulation materials that can be used in a cavity. The biobased materials that do exist are more often used in renovation projects rather than new construction projects. In addition, moisture management can become a problem since biobased materials have different moisture absorption properties compared to traditional insulation. Lastly, onsite construction processes, including weather exposure, can influence the performance of biobased materials. To address these challenges effectively, it is essential to identify and understand the potential problems that may arise when biobased insulation material is being used. From several biobased materials, the properties and pros and cons are elaborated according to basic criteria. Hereafter, a score card (multicriteria analysis) is made which elaborates on all materials related to the criteria. Out of the score card, the three best materials are found which can be used as replacement of insulation in the traditional cavity wall.
