Robust Internal Thermal Insulation of Historic Buildings - Impact of water repellent agents on hygric properties of porous building materials

The insight that hydrophobization should be regarded as a possible element in the spectrum of internal insulation solutions triggered the midway introduction of RIBuild’s Task 2.4 ‘Impact of water repellent agents on hygric material properties’ and this deliverable reports the findings of that task. While giving much new knowledge and insights in regard to water repellent agents and hydrophobization, it also reveals that the results and outcomes show significant limitations and incongruences still, and that much more work thus is needed before hydrophobization can be reliably considered as part of the solution spectrum for moisture damages possibly resulting from application of internal insulation. Therefore, the findings of Task 2.4 have not resulted in adopting hydrophobization in the simulation campaign for the webtool of RIBuild’s WP6. ispartof: pages:1-159 status: Published online
