I raised this some time ago but no workable solution came out of it. I want to apply solar film to the inside of my condo windows to help reduce the heat entering the unit during the day (especially this time of year). Have tried to research through some supplier webs sites (eg. 3M) but have not yet been able to find businesses in BKK that would do the service (provide quality film and install). Appreciate hearing from anyone out there who has successfully done this, as well as getting an indication fo cost. Thanks RS

There are loads of automotive specialty shops that install solar film by 3M and others. They all have books with samples and statistics. I can't see why they wouldn't be happy to come and install the film on your windows, which would probably be much simpler than on a car with the curves and odd shapes.
