What is Cellulose Insulation?

We install cellulose insulation in St Paul and Minneapolis, but there are a lot of people out there who don’t know what this type of insulation is and why it is such an environmentally-friendly and budget-friendly option.

Cellulose insulation is one of the oldest types of building insulation materials, but it has come a long way since its humble beginnings. Nowadays, cellulose insulation is made out of recycled newspaper that has an added fire retardant, like boric acid. It’s also known as blown-in insulation, and the most common type of cellulose insulation is called loose fill. It became popular in the United States in the 1970s.

Because it is made out of recycled newspaper, this is an eco-friendly way to keep your house warm in the winters and cool in the summers. It uses up to 85% recycled materials. When you have cellulose insulation installed, pellets of the cellulose are blown into your home’s walls or into its attic. It fills in cavities, and no pressure is placed on the insulation.

Its R-value is 3.5 per inch of thickness. And although it can soak up moisture, it does very well against insects and vermin like mice because of the fact it is treated with borates. Cellulose insulation is generally your only option when you are trying to insulate closed walls (because it is blown in, so it does not require you to put large holes or openings in your walls in order to insulate your home).

And it doesn’t just insulate your home from the outdoor temperatures. It’s also a great noise reducer, vapor barrier, mold and pest controller and fire retardant.
