I live in a historical home in the USA, it was built before insulation was invented, It gets very cold here in the winter, -14C and very hot in the summer 39C, thus a siding that looks like "Sear" brand 1920's metal siding yet helps keep the home pleasant to live and work in, is what I was looking for and Shandong ShangHe New Construction Engineering Co. Itd. Made a thick siding just for my needs. Thank you so much.
