QUOTE(DarkNite @ Jul 3 2023, 01:31 PM) What is the cost vs this? just lay the radiant reflector on ceiling there i think at least save 50% of material.  and this is just radiant reflector, your rain noise will still be there unless you add insulation layer. |

QUOTE(wkchia @ Jul 3 2023, 01:43 PM) This will save some cost but wont be as effective to shield the heat. Shielding below the roof tile will stop the radiation from heating the air in the roof thus reducing the heat transfer in both radiation and conduction. If you shield only the ceiling, the heat from the roof tiles will heat up the air in the roof area and trap the heat become like greenhouse. that look like a ventilated roof, the temperature won't get that high. the main heat flux will still be the radiant from hot roof tiles. |
