I am looking for recommendation, what kind and where to buy window films for my Condo. Want to do this before the next month hot season.

I was thinning to use 40% film

Appreciate any thoughts/recommendations

I just put some on my shop on Soi Khao Noi, I used a car shop along side Sukhumvit. Be prepared the film is not cheap. It cost me about 30,000 baht to do 3 large windows and door. If you need a referral PM me and I'll give you the number of the shop.

Also be aware you may not be happy with the amount of light reduction (which is permanent) - living in a cave does not help some people keep a happy face. For some shades might be a better option.

You need either a high reflective film or a dark tinted one to reduce the amount of solar radiation shining into the room. The dark tinted one will not cut down on heat as it will cause the glass pane to be very hot and conducting this heat into the room. The highly reflective film will throw a glare of sunlight to someone else.

Note - Some windows with reflective glass in the office building of Kasikorn bank at Phaholyothin road was shot at by disgrunted victim(s) of reflected glare when the building was just opened. Do you want to risk bullets flying through your windows?
