Our Commitment to Conservation and the Environment

J & L Insulation Inc. is more than insulation, we are Energy Conservation. Insulation is one of the few sub-trades in construction that will pay for itself during the lifetime of the home or commercial building. When you upgrade your insulation envelope the savings will be even greater.

Johns Manville our fiberglass insulation supplier incorporates 20% post-consumer and 5% post-industrial recycled glass content in their manufacturing process. That is more post-consumer recycled glass than any other fiberglass insulation manufacturer. Other reasons to choose fiberglass insulation:

  • What is not made from recycled materials is made from sand, an abundant and rapidly renewable resource.
  • It can be reused when a building is remodeled or demolished.
  • It is highly compressed when packaged, requiring less plastic wrap and less space while in transit, which reduces fuel demands, which reduces the carbon imprint on the earth.


In 2002, Johns Manville eliminated formaldehyde from their fiberglass building insulation. Johns Manville is the only fiberglass manufacturer that manufactures a complete line of Formaldehyde-free fiberglass building insulation. Building with Johns Manville Formaldehyde-free insulation contributes to prerequisite and point opportunities with:

  • U.S. Green building Council’s Leadership in Energy and Environmental Design (LEED) program.
  • National Institute of Standards and Technology’s Building for Environmental and Economic Sustainability (BEES 3.0) program.
  • Us Army Corps of Engineers’ Sustainable Project Rating Tool (SpiRiT) program.


Cellulose insulation and Ultra touch cotton insulation, products we use at J & L Insulation, are both manufactured using 85% recycled content.

Choosing J & L Insulation as your insulation contractor is an easy way to help protect the environment. At J & L Insulation, we know we all play a role in building the future, in San Diego County, California, the United States and around the world. As the demand for energy continues to grow, the importance of energy conservation and recycling becomes even more critical. When you use J & L Insulation as your sub-contractor, you have a positive impact on the health of the planet. And that makes a world of difference.
