that 'Reflectix', and other brand names, is pretty much like Mylar, bonded to various materials (Google 'reflective insulation') ... it's in big rolls for spreading in your attic ... it seems to be the 'new wave' of heat insulation for housing ... pretty expensive, as several web sources, seem to only sell it in huge rolls (their 'target customer' is building contractors, etc...) ... the main claimed benefit is that it reflects heat, and doesn't pass moisture ... I have previously seen lists that place flat white paint up around 85% reflectivity, so I used to use it (no idea what the correct numbers are, but it was damned bright when I stuck my head in the cabinet )... now, I have Mylar, and am planning on a new cabinet ... it's a tossup, I may just go back to flat-white paint, or, those white Melamine-surfaced panels at HD ... the Mylar is just too fragile, even washing with Windex and a soft cloth dulls the surface ... :smokin:
the image reaper Reviewed by the image reaper on . Myler vs. chrome tape? I might be splitting hairs but I have a great deal of both available and from the comparison in my head they are about equal though the chrome tape would probably be a little easier to work with and apply to the inside of my grow box. Any opinions? Rating: 5
