Good-quality insulation is beneficial to the environment in that it reduces the energy requirements to heat or cool a home. You should add as much insulation as will fit in your walls. Using eco-friendly insulation is a great way to go the extra mile in taking care of the environment.
One of the first things to look at is whether the insulation uses formaldehyde as a binding agent. Most do, but green insulation will be formaldehyde-free. Next, you want to consider what materials are used to create the insulation. Look for those made from natural fibers. Wool and cotton are popular choices, particularly if made from recycled clothing, such as blue jeans. Eco-friendly blanket insulation will usually be made from one of these two substances.
If you prefer loose-fill insulation you can find some products made from recycled newspapers. Make sure only natural chemicals are applied to make them fire resistant.
For some people the spray-in foam types of insulation work best. Here, scientists have found yet another use for soybeans. You can get spray-in foam insulation made from soy that works just as well as other spray-ins but without the environmental drawbacks.
By stuffing your walls and ceiling full of eco-friendly insulation you can make a dramatic difference in the environmental footprint of your home.
