Creating your own insulation from recycled paper is not only an environmentally friendly option but also a cost-effective way to improve your home’s energy efficiency. Cellulose insulation is made from recycled paper products, making it a sustainable choice that can help reduce your heating and cooling costs. In this guide, we’ll explore three diverse and practical examples of DIY insulation using cellulose.
If you have an attic that’s poorly insulated, it’s a prime candidate for adding cellulose insulation. An uninsulated or poorly insulated attic can lead to significant heat loss in the winter and heat gain in the summer, making your home less comfortable and increasing energy bills.
To insulate your attic, first gather the recycled paper (like old newspapers or cardboard) and shred it into small pieces. It’s best to use a paper shredder for this step. Next, mix the shredded paper with a flame retardant, which you can purchase or make from a solution of borax and water. This step is crucial to ensure safety, as unprocessed cellulose is flammable.
Once you have your mixture ready, use a blower (which you can rent) to fill the attic space. Make sure to wear a mask and goggles to protect yourself from dust. Aim for a thickness of around 10-14 inches to achieve optimal insulation. Finally, seal any gaps or holes in the attic to prevent air leaks, which can undermine your insulation efforts.
Retrofitting your walls with cellulose insulation can significantly improve your home’s energy efficiency. Walls are often a source of heat loss, so adding insulation can create a more comfortable living environment.
To insulate your walls, you’ll need to drill holes into the wall cavities. Start by measuring the height and width of your walls to identify where to drill. Use a drill to create small openings, ideally 2-3 inches in diameter, every 24 inches along the studs.
Prepare your cellulose mixture by shredding recycled paper and mixing it with a flame retardant. Then, using a cellulose blowing machine, fill each wall cavity with the prepared insulation. Ensure that the cellulose is evenly distributed so that there are no gaps. Once filled, seal the holes with a patch or wall repair compound to restore the wall’s appearance.
Basements can be notoriously chilly and damp, making them uncomfortable spaces. Insulating the walls and ceiling of your basement with cellulose can help maintain a more consistent temperature and reduce energy costs.
Start by preparing the cellulose insulation by shredding recycled paper and mixing it with a fire retardant. Check for any moisture issues before insulating; if there are leaks, fix them first.
Apply the cellulose by blowing it into the walls of the basement. If you have exposed joists in the ceiling, consider adding insulation there as well. Make sure to create a barrier to prevent moisture from seeping in, which could compromise your insulation over time. For added protection, use plastic sheeting as a vapor barrier along the walls before applying the insulation.
