If the summer is covered with a layer of reflective material as the foil on the roof can act as insulation to what extent?
Attic indoor heat insulation method 1: heat insulation layer.On the roof of a layer of insulation, the sun directly on the heat insulation layer, the higher temperature can be insulated layer and the roof of the air between the guide, to prevent the roof ceiling temperature is too high. The heat insulation layer can be laid with pre cast concrete insulation bricks or other new materials, but avoid using new materials to prevent fire.However, the laying of the heat insulation layer is troublesome and affects people on the roof. Therefore, the use of insulation for indoor heat insulation in the last two years is beginning to show a downward trend.
If this layer of reflective film overhead, between the membrane and floor to retain 150 ~ 200mm of the air flow layer, the effect will be very good.
Basically solve 60% of the problem. The rest is to think about this layer of metal. The reflecting film itself will become very hot and heat will continue to pass to the floor.
