Low-E Glass Applicable to Existing Window Panes on the siteFeatures“ATTOCH” is a window renovation product which enables achievement of energy-saving performanceequivalent to that of the Low-E Pairglass units with attachment to existing window panes of officebuildings and stores. It is effective in heat shielding and insulation, energy saving and prevention of dew
condensation and realizes a comfortable indoor space.

Basic Concept or Summary

On-site conversion of existing window glass to Low-E Pairglass
Low-E film

What is Low-E glass?
Low-E glass is glass coated with a special Low-E film which
prevents heat radiation. It passes the light but reflects far-infrared
radiation from solar radiation and heating and, thus, improves
indoor thermal insulation.
ATTOCH enables achievement of the performance equivalent toLow-E multiple glass by attaching a pane of Low-E glass to theexisting window pane from inside.

Side of the building

Front of the building* The reduction rate is based on a comparison of the 6mm glass air conditioning cost.
* In this simulation, the reduction in the air-conditioning cost at the time of the renovation with ATTOCH is estimated. This simulation is for a simple mathematic
evaluation and its result does not guarantee the energy saving effect of the window renovation.
* The reduction ratios mentioned above were obtained in the simulation with Classic color ATTOCH.
