TEMPERATURE-EXPANSION INDICATOR FOR SIDING PANELS

摘要

A temperature indicator for a siding panel senses panel temperature and indicates on a graphic scale the corresponding effect of thermal expansion over differences in temperature. The temperature indicator can be various forms of contact thermometer; temperature strip or sensor and can be integral or temporarily affixed during installation or for later assessment for correct panel gapping. The indicator shows how closely the edge of the panel can be placed to an adjacent surface while avoiding interference over a range of thermal expansion temperatures.
