Need to alter window to view one way?

Question

I`ve heard that there may be a stick on material that will change a window to still allow light in and viewing out but stops anyone looking in from outside. Does anyone know if such a material exists and if so where I can buy it?

Answer 1

It's called a window shade.

Answer 2

ask at  GLASS shop

Answer 3

Solar reflective film - it works when the ligtht levels outside are brighter than the interior, though. At night with the light on inside you would be seen, unless you draw the curtains (This is true of net curtains too).

Answer 4

tinted sheets. i think you can buy them on glass stores.

Answer 5

Yeah,  Lowe's and Home Depot carry it.
