SUN BLOCK SCREEN

Where is summer heat from ?

In recent years, it is amazing for the office building and house to be well-insulated and hermetically-sealed. Especially it is becoming commonsense to use double-glazing in the housings and condominium buildings for energy saving at the moment.
However , the countermeasures that we often use are the device for energy saving, not the know-how for cutting off the influx of the heat, so it is not solution for the fundamental problem. Lo and behold, it is said approx. 73% for the heat to inflow from the openings in the summer season. Thus, otherwise we could control the heat influx from the openings, it would be too much to say that we couldn't expect good effect for energy saving.

Do you know howto decide the electricity charges?

In Japan, the electricity charges (contract fee )is decided based on the largest point of using electric in the year .Or, in generally, it is decided by the usage of summer season because summer season is the largest usage of electricity. That means if the usage of summer could be controlled, that would be short cut to success for saving money. It would be reduction of power generation and contribution of prevention of global warming if the electrical usage in summer could be reduced.

Sun Block Screen is a efficient heat sealed system.

?Saving Electricity Charge Test?
Test situation : In a ten-tatami room, setting 26oC of air conditioner. Installing Sun Block Screen on the outside window.
Result : Saving cost Approx. JP 17,000 Yen /room in a summer season
(The result is compared with last summer season. This test was done in a conventional home.)

Solar Transmittance

SC(Shading Coefficient) is represented by Solar Transmittance which is indicated how much percentage of solar radiation is entered in a room. The less the rate of solar transmittance in the summer, the better comfort. (Remark: Solar Transmission is changed by the regions and the circumstances.)

Remark: Sun block Screen is used for shading coefficient.
When it is strong wind or hard rain, please roll up the screen and please don't use.
(It could be changed form of the body or dropped due to wind pressure or so.)
