Window films

A local museum is considering cutting down light and uv passing
through the windows of storage rooms by applying aluminium foil to
the inside of the glass. This would reflect light back out through
the glass.

Are there likely to be problems with this? Could heat build up in
the glass and cause a problem? Would the heat build-up in the foil
cause a problem? I've checked the Cons DistList archives and maximum
temperatures of 121 deg C have been measured at Monticello between
window glass and interior storm window panels.

Does anyone have any suggested adhesives to hold the foil to the
glass?

Alternatively, the foil could be applied to rigid panels, mounted
inside the window but allowing air to circulate between the panel
and the glass. What do colleagues think of this as an option? It's
more expensive, of course.
