What is it?
Microfiber PLN is unfaced (plain) glass wool; the maker's website calls it Plain Blanket and Plain Board. The maker's general-purpose sheet says it comes as rolls and boards, with a "Non Water Absorption" additive to reduce water and moisture uptake. Used for both thermal insulation and sound absorption.
What is it made of?
