Hi @edfe66a5, I apologize if my previous response was unclear. Radiant barriers are designed to reflect radiant heat, which is the transfer of heat through electromagnetic waves. Radiators, on the other hand, produce heat through convection, which is the transfer of heat through the movement of fluids. Therefore, radiant barriers are not designed to reflect the heat produced by radiators.

Regarding your question about the heat produced by a house, radiant barriers are typically installed in the attic to reflect radiant heat from the sun, which can help keep the house cooler. The heat produced by the house itself is not typically reflected by the radiant barrier back inside, as the barrier is designed to reflect radiant heat from the outside.

I hope this helps clarify things. If you have any further questions, feel free to ask!

Is not clear. The radiator prosuce heat and propagate it inside the house. The heat is energy. This energy can be reflected back by aluminium foils acting as radiant barrier. So why would not a radiant barrier reflect the heat produced by radiators back inside the house

You are correct that a radiant barrier can reflect heat back into a space, including heat produced by radiators. However, the purpose of a radiant barrier is to reflect radiant heat, which is different from convective heat produced by radiators. Radiant heat travels in straight lines and heats objects it comes into contact with, while convective heat is the heat that is transferred through the air. So while a radiant barrier can reflect radiant heat, it may not be as effective at reflecting convective heat produced by radiators.

Explain the difference from radiant heat and convective heat

Radiant heat is the transfer of heat through electromagnetic waves, while convective heat is the transfer of heat through the movement of fluids (such as air or water). Radiant heat can be reflected by a radiant barrier, while convective heat cannot be reflected in the same way. Radiators produce heat through convection by heating up the air around them, while a radiant barrier reflects radiant heat.
