Who is secretly stealing my money?
Solar radiant heat is you again!
In addition to the windows, heat will also cross the walls! When the sun shines during the day, the cement wall absorbs heat. At night, even if the house gets cool outside, the walls inside the house are still releasing heat, especially the room of the west-facing wall ~
🏜Put a wardrobe and bookcase on the west-facing wall, let the books or clothes absorb heat, reduce the heat outside the wall passing into the room, or use insulated building materials and install double-walls.
🏜It has better sunshade effect outside the west-facing wall, can be painted with heat insulation, or use a wooden lattice bar.
If the "insulation" work is done well, it can effectively reduce the indoor temperature, and can also reduce the air-conditioning power consumption!
