San Francisco, known for its commitment to sustainability and environmental consciousness, offers a variety of eco-friendly home insulation options. These materials not only help in reducing energy consumption but also contribute to a healthier living environment. Here’s a look at some popular eco-friendly insulation options available in the area:

1. Cellulose Insulation

Cellulose insulation is made from recycled paper products, primarily newsprint. It is treated with a fire retardant and is an excellent option for insulating walls, attics, and floors. This material is known for its high R-value, meaning it provides good thermal resistance.

Benefits:
High recycled content, making it an environmentally friendly choice.
Effective at reducing air leaks when properly installed.
