I made it to the predecessor Hijet. There are places where the position of eyelets and hooks does not fit. The texture is blue seat. It looks weaker than green. Perhaps it's better not to use it only this time instead of year-round.
It is used for thermal reflection for solar water heater (vacuum water storage tube). In the summer, it covers the surface and heat shields, in winter it stretches to the back side and uses it for heat reflection. Regarding durability, there seems to be no problem if it deals with scratching etc. carefully.
I put it on the balcony for the purpose of shielding the sunlight. When the surface temperature of the floor surface (concrete) was measured with a radiation thermometer, the portion that received direct sunlight reached 57 ° C, while the portion covered with this sheet was 27 ° C. It has excellent thermal insulation performance.
