Hello everyone I am new here in the forum. I recently bought an old wooden house (built 1920). The roof was renovated about 5 years ago but not insulated. I now want to properly insulate the roof. It will not become a living space, because after insulation it is too small. Now I have questions about this: - The first layer of Homatherm Holzflex 100mm will be clamped between the existing rafters. The second layer (exactly the same product) I want to simply attach on top (double-sided tape on the lower layer or on the rafters), but without doubling the rafters (lengthwise/crosswise) because then I create fewer thermal bridges. However, this causes the problem that I cannot properly attach the finishing OSB-3 board 18mm. I could now screw wooden cubes 100x100x100mm onto the existing rafters at certain points and attach the boards to these or drill through the 100mm Homatherm mats with long screws (probably extreme thermal bridge). Has anyone faced this problem before? I am very grateful for all tips and tricks. Many thanks, Nick
