Help On Solar Film/Privacy Film/Frosted Film

[navik 0]

The windows in my resale unit comes with frosted film. Some of the windows' film have shrunk and the edges are now super stick and disgusting. I'm having them removed and considering if I should repaste with Solar,Privacy or Frosted film again as its a corridor unit.

I have a few questions:

1) Was the shrinkage of the original frosted film due to poor film material or poor workmanship? Does the heat, i.e. sun ray actually cause the film to shrink, cos some of the windows along the same row are fine.

2) Can we install privacy film on HDB windows? I was told that its reflective, and might get complains from people living opposite, in which case HDB might ask us to remove...

3) Anyone got good recommendations for film installer?
