What is SUDARE

What is SUDARE?

Originally SUDARE means A Bamboo Blind.

It has been widely used in Japan from Y759.


SUDARE with AGC

Use Hard Coat Low-E as back glass.

Then, achieve better Performance of GIPV.

From 2012 More than 150 Project in Japan

To upgrade existing building Improving Energy Efficiency


What is Attoch

36

Secondary Sealant

Coating • Attoch converts single pane windows into Low-E double glazing unit (DGU) onsite.

Advantage: Improve Energy Efficiency of buildings Provide thermal comfort for tenants Fasten new high performance glass to existing

glass on Site. Without Scaffold, inside work only

Building Integrated PV brings additional value

Allows natural light into the building

Shading

Reduces solar heat gain

Safety

Sound Insulation

……and many more functionality

PV modules can be aesthetically pleasing

Can be used to replace other building materials

Application is limited only by the imagination

PV Modules need not be only on the roof
