You can install it on the exterior and pick up a little extra performance. You then are trading some longevity of the product. It is mostly customer preference. This installation was installed for fade protection not heat rejection. So, picking up that extra heat rejection was not a huge concern for our client. Thank you for watching!
3M prestige does an exterior and interior version both with 10 year guarantees. They're rated to 1.02W/m^2K Double glazing at around 2.5. So adding another layer would in theory be a 30% reduction.
Assuming those are double paned windows - if the film reduces heat, would it not work better if it was installed on the exterior of the window?
