Needled Insulated Lining.   Consists of hollow, polyester fibre needlepunched through Mylar.  The hollow fibres resist conduction while the reflective Mylar resists radiant energy.  The energy, hot or cold, is reflected back to its source.  like Warm & Natural, Insul-Bright is easy to sew and your finished projects can go right into the washer and dryer and will not break down over time. 

Approximately 22" wide.  Sold by the metre.
