∙ 12y agoThe r value of a material can be calculated by dividing the thickness of the material by its thermal conductivity. In this case, the r value would be 2 inches (4 inches / 2.0 = 2.0).
A material with low thermal conductivity, such as aerogel, is known to have the best thermal insulation properties. It is lightweight, highly porous, and has excellent heat resistance, making it an efficient insulator.

For a pad 24' x 26' x 8" thick, you would need approximately 38 tons of crusher run. This estimate is based on the volume of the pad and the typical weight of crusher run material. It's always recommended to consult with a local supplier for a more accurate estimation.
Air is a good thermal insulator because it is a poor conductor of heat. In materials like fiberglass insulation, air pockets are trapped within the material to reduce heat transfer. This is why double-pane windows and insulated walls are effective at keeping heat inside a building.
Good insulators of cold typically have low thermal conductivity, which means they do not allow heat to easily transfer through them. Materials with a lot of trapped air pockets, like foam or fiberglass, are good at preventing the movement of heat. Additionally, materials that are thick and dense can also be good insulators of cold.
