Heat insulation for a rafter roof

摘要

The invention is intended to ensure a good cost-effective heat insulation in a roof structure. By providing a heat-insulating-material fill between the rafters, holes and slots, which let heat escape, are to be prevented. The netting webs are fitted on the rafters, transversely thereto. The netting webs have a left-hand and right-hand bent-over portion in the longitudinal direction, with the result that, by virtue of pushing the bent-over portions one into the other, they can be fitted together to form a large-surface-area netting. Nailing boards or laths over the netting webs, onto the rafters, holds the webs and stretches them between the rafters, said nailing resulting in ventilation (through-ventilation) and it thus being possible, in the event of moisture occurring, for the heat-insulating fill to be rapidly dried out again.
