Attic heat transfer.

In essence they reflect the light back from where it came keeping it out of your attic. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. Passive attic vents are the vents installed in attic during the construction to let moisture escape from an attic in the event moisture gets into the attic. On a cold day.

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.

It s just occurred to me.

Temps upstairs are fine in winter. Your attic can get as hot as 150 degrees in the summer. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

That s telling me the reason the upstairs gets hot is because of heat transfer from the roof attic. Heat moves around your home by conduction convection and radiation. 4 ways to reduce attic heat in your home. That air moves by conduction through the ceiling to the attic floor.

Radiant barriers are made from highly reflective material and they work to keep an attic cool by preventing the electromagnetic transfer of heat. A radiant barrier works best when it is perpendicular to the radiant energy striking it. How heat transfer works in a home.

2 all the hot items in the attic framing sheathing toys boxes insulation dust etc now begin to conduct or transfer. Many homeowners falsely assume that since their attics are extremely hot in the summer the best way to reduce their cooling load is to get the heat out of the attic.
