So you're telling me that adding foil to a plastic sheet is cheaper than making a white plastic sheet?
Even if that were true, there would be expensive white insulation for high performance applications. Just like you can get aerogel (bulk) insulation where you don't have the space to use cheaper stuff but still need to meet required performance targets.
Fun fact, I almost did aerogel insulation under my headliner. Might still do it since I have to drop it soon.
