Main Applications

Membrane structures

Large-scale facilities such as factories, warehouses, airports, etc.

By installing on the roof and exterior walls, heat input due to solar radiation is minimized, and the interior space can be cooled with zero energy.
It improves air conditioning efficiency and is expected to save energy and reduce CO2 emissions.
