CONGRUENT GLASS AND ALUMINUM
Reflective glass, or sometimes known as one-way mirrors, are primarily used to attain greater privacy for the occupants of a room. From one face of the glass, which looks like a mirror, an individual can not see what is on the other side while from the opposite face of the glass he/she can see clearly what is on the other side.
This picture shows a dark green reflective glass installed on a cathedral window of a house in Charlemagne Street BF Resort Village, Las Pinas City. From the outside, which is the mirror face of the glass, the stairs behind the window can not be seen. if you will go inside the house, you can clearly see the outside thru the dark green face of the reflective glass.
