hi, think the sun-x was like $4.50 per sq ft or something.. think total i paid like 2k+ for the entire house, except kitchen windows - mbr (5 panels)
- 2 bedrooms (5 panels each)
- side balcony (4 panels)
- balcony (6 panels)
i tried self apply (not ikea, but some korean brand that i got from the market) - it blocks of the sun, but does not reduce the heat..
basically the film reduces the glare that comes into the house - i have a mbr which gets the full frontal of the sun in the morning (but if i close the windows at like 15 degrees angle and close the curtains.. can still sleep with fan.. no aircon..
