3m copper low-e

Does anyone know if 3m still makes copper low-E film?

I'm not sure if it matters but I can't find anything about it on the 3M website.

ask vclimber?

discontinued a few years ago, damn shame we used a fair amount of it but not enough to keep em happy I guess

They make LE35

LE's were a great film however terriblely marketed. Back when they were sparking interest they had a 5 year payback and lasted about 7 years on the sunny sides, longer on the northsides. However with the energy cost having skyrocketed while the cost to install film has actually gone down the payback must be less then 3 years for some. I can't understand that in an energy crissis that started a few years back that they also discontiued the best performing film from any manufacture, as far as energy savings. I do have a few short rolls of this stuff left if any one has touble finding it for match ups.

No copper in caves ?

I would think copper would last longer in a cave rather than on a window
