For those purposes, why would it need to be mirrors? We don't care to coherently reflect the light; we just want to block it.
(For reference, I think all of these are likely to be somewhere between moderately and incredibly bad ideas...)

The energy has to go somewhere. If you're not reflecting it you're absorbing it and you eventually have to do something else with it.
In fairness, a white sheet and a mirrored sheet will have much the same impact in this regard.
