Adjustable flat roof fastener for slope insulations
Flat roofs are usually not completely flat, but have a slight slope, so that rainwater can drain off in a predetermined direction. For a slope insulation, the installer must use a correspondingly long fastener for each insulation thickness when fixing the roofing membrane. Flat roof fasteners which are adjustable in height are easier and more economical. As for example the EJOT JBS-R/EcoTek.
Standing water puts strain on the roof membrane and can reduce the service life of flat roofs. For an effective drain of rainwater, flat roofs are therefore formed with a slight slope. The flat roof directive prescribes a minimum slope of two percent.
