Micafil is a unique loose-fill product that is ideal for use in internal wall and loft cavity insulation.

Vermiculite is a versatile mineral that can be easily poured into any cavity - between floors and under stair voids - in a way that no other insulation material can.

Micafil is an ideal insulator and can reduce sound transference between rooms partitioned by stud and plaster-board walls.

Micafil is made from Vermiculite - a naturally occurring mineral that is expanded to 10 times it’s original size to create high insulation properties, making it perfect for domestic loft insulation applications.
