How insulation works wiki?

The act of insulation is accomplished by encasing an object in material with low thermal conductivity in high thickness. Decreasing the exposed surface area could also lower heat transfer, but this quantity is usually fixed by the geometry of the object to be insulated.

Does a steel door insulate better than wood door?

Steel doors are less expensive than wood doors, although there are low-end wood doors that are comparable in price. … Steel doors are typically more energy-efficient than wood because they have higher insulating values, so they’re better at keeping conditioned air inside your home and outdoor air outside.
