Basement Insulation

A Simple, Green Way to Insulate Basements

The ECOCELL blanket system is the ideal choice for crawlspace and unfinished basement insulation. Made from recycled and renewable fibers, ECOCELL blankets have superior thermal and noise absorption properties and are code compliant. 

ECOCELL blankets are Class A fire rated. Therefore, they can be left exposed and do not need to be covered with drywall, paneling or other material resulting in less cost for the consumer compared to other basement insulation materials.  

ECOCELL blankets contain no harmful airborne particles, and do not itch or irritate skin like  fiberglass insulation. Available in two convenient thicknesses and sizes and easy to install without requiring special equipment, ECOCELL blankets are the ideal insulation solution for unfinished areas or the do-it-yourself individual.

For homes or structures with finished spaces in the lower level or basements, Nu-Wool Premium Cellulose Insulation using the WALLSEAL system is a solution for the sidewalls and exterior walls.
