| Abstract:From the perspectives of anti-condensation on the inner surface and heat insulation in summer， the thickness of the thermal-preservation （thermal insulating） layer of the steel structure roof was calculated and analyzed， which adopted by the representative cities in the hot-summer and cold-winter zones and the hot-summer and warm-winter regions， respectively. It pointed out that the thickness of thermal insulating would be greater than the thickness of anti-condensation in winter when the indoor temperature and humidity reached a certain state in summer. Therefore， the thickness of the steel roof insulation layer of the papermaking workshop in hot-summer and cold-winter zones should be calculated by its thermal insulating in summer and checked by the anti-condensation in winter； for hot-summer and warm-winter zones， it should be calculated by the anti-condensation in winter. |
