Roofing membrane temperature indicator |
摘要 |
A roofing membrane temperature indicator is provided for preventing the installation of a roofing membrane or roofing membranes at a temperature below a minimum recommended installation temperature for the roofing membrane(s) and/or a minimum recommended installation temperature for the roofing membrane(s) for a particular installation procedure. The membrane temperature indicator is visibly associated with the roofing membrane(s) and includes a thermochromic indicator having a first color at temperatures below a designated temperature and a second color visibly different from the first color at and above the designated temperature. The designated temperature at which the color of the membrane indicator changes is at or above a minimum recommended installation temperature for the roofing membrane(s) and/or a minimum recommended installation temperature for the roofing membrane(s) for a particular installation procedure.
