energy conscious homeowners often insulate their homes.
one form of insulation is thick pads of loosely packed glass fibres.explain how these pads reduce heat transfer.
how do thick curtains help reduce heat loss from the windows of a house?
builders often insulate parts of homes with material that consist of a thin shiny sheet of reinforced aluminium foil.how does this material reduce heat transfer?
The pads do not conduct electricity, and reduce convection due to trapping air.
1) Stops heat loss by trapping air in micro-air pockets.
2) Blocks heat from getting to glass window surfaces where it could transfer by conduction from the house.
3)Reflects heat
