The guarantee ensures that, when properly installed in a building structure, straw bale will maintain the thermal and sound insulation properties specified in the performance declaration and will continue to perform its insulating function throughout the life of the building, provided that the building structure is not destroyed or exposed to any effects that would damage the material.
