Around the globe, people are making decisions every day in an attempt to be more eco-conscious. Recycling and reducing energy consumption are two of the best ways to make a positive impact, so why not combine the two with plastic bottle insulation?

Giving them new life between your walls or in your attic or basement will reduce heating and energy costs in your home and save you money on expensive insulation. Why not?
