Hi,
I have had 1 of my front timber window glass replaced by builder due to imperfection.
After the changes i notice the new glass is a lot more thinner than the other window, but i have no idea how
to identify if they are double glazed or just a normal piece of glass?
I tried knocking on it, the new glass gives a lot more crispy noise than the other windows. I light up a candle and place next to the window, the old glass gave me 2 candle light shadow, but the new glass on 1 shadow, but i am not even sure if this is the right way to identify them.
can anyone teach me how to identify glazing vs non glazing window?
