ArmaflexC0-09x015-A 15x9, Black

Hi is this suitable for outdoor pipe protection from freezing?

Hi, is this suitable for outdoor fully exposed to elements?

Could the seller please confirm whether this 9mm thick/15mm bore hole lagging is self-seal (one review says it's not).

Hello can someone please confirm this insulation is proper black like the picture shown and not grey like the ones you get in b&q, screwfix etc?thanks
