Thanks for the reply guys, hmm seems like blinds/curtains are still required. Any better ideas to contribute?

We are using Llumar from Window Cool too... Had chosen the privacy file which the highest heat reduction (colour is greyish inside and from outside is reflective), that cant really see thru from outside unless u are standing near to the window wif the light on... Didnt have any curtains or blinds installed at all. So far is good, the heat reduction in the room was cool... Cant really feel the heat even it is a sunny day.. Bad - cos of the privacy film, ur room look dimmer in day light and might need to switch on light if u are not used to it...

i'm also looking for solar film contacts. besides llumar from window-cool, any other brands/suppliers to recommend? please pm me. thanks!

does anyone who use solar film has this "rainbow effect" on the windows during night time when the light is on?
