corrode or change color?
BTUFOIL™ is produced with a metalized aluminum. This surface is highly resistant to discoloration or corrosion. Lesser products often contain ‘fillers’ – often, it is these fillers that are discoloring, not the aluminum content itself. For this reason, BTUFOIL™ is always produced with the highest-quality metalized aluminum available. BTUFOIL™ is also coated with a clear resin to further protect the integrity of the surface.
