double glazed is not enough *even* if you take double glazed with a slight tint/UV rejection. been there done that. if you have sunshine on the windows a good tint is required. got raybarrier on top - helped a lot. if it peels, its easy to change and cost is trivial compared to cars. can tint a whole house for a price of a sedan

using mine for three years. no peel, no bubble. i think the key is to buy a highgrade tint not the cheap junk.

i think the key is a reputable company like rike cool, etc. i personally would not use v-cool in the house since the metal should interfere with reception for phone (not sure though) and the tint tends to oxidize (in two cars before, now only using ceramic based tint) also when i checked with them their pricing for house was ultra high. glassbrella i never heard of is that the brand they use for their rike cool tint when they stick it in the house-windows? for 2bucks you probably get what you pay for. 4-6 should be a better option. for that price a decent film can be made and installed by ppl with experience (so it looks good on the window too).

costly. spoke with them and their pricing was way more than what i was willing to spend on my window tinting. i cant remember the figure anymore (been 2 1/2 yrs) but i think it was at least more than 4x my tint pricing.
