Insulation is one of the most important factors that play into your home’s energy efficiency. Proper insulation regulates indoor temperature more effectively, minimizing drastic fluctuations thus helping you conserve energy and lower your heating and cooling bills.
- Greenfiber®, manufactured in the U.S., is made from post-consumer paper fiber and free from toxic substances such as formaldehyde and asbestos. Greenfiber® uses 13 times less energy to manufacture than fiberglass insulation and cellulose-based insulation has been proven to reduce heating and cooling bills by up to 25% and sound power by up to 60%.
- Icynene is a foam insulation that sprays into building cavities and expands as a solid, spongy mass, effectively sealing off cracks and crevices. Some icynene products are partially made from castor oil (from the drought-resistant castor oil plant, Ricinus communis) while other products are starting to include recycled PET content. While icynene is an eco-friendly insulation alternative that adds to the energy efficiency and structural integrity of a home, it is far more expensive than fiberglass and is so airtight that it can impede on proper ventilation.
