Unique Design
Finer fibres are designed to fill tight spaces around pipes, wires and electrical boxes, even in homes with existing insulation. It installs through very tiny holes using our Dense Pack process, ensuring that it will not settle over time.
Reduced Air Infiltration
JM Spider insulation reduces air infiltration more than cellulose because of its much smaller fibres.
This gives even better performance and increased comfort in your home.
