We are almost finished building a house near prasat, Surin. All we have left to put in are the windows. I said in passing to my wife that we should get double glazing and then tried to explain to her what that means. She has talked to a few windows shops and of course they don't do that in isaan but they have come back with this technique of sandwiching together two 3mm sheets with a film in the middle. One shop said this will stop it from shattering if it breaks and reduce noise. Another shop said the problem is over time the film will degrade and it wont look as good to look through. They said they can do it but suggested instead to use a single 6mm glass sheet for each window with is cheaper. Does anyone have experience with this double sheet with the laminate? What is the best option?
