What is blow-in insulation, and how to install it?

Having multiple layers of clothing is one way to stay warm in a house that is poorly insulated.

Still, your furnace will work overtime to ward off the cold, and the water pipes of your home could be in danger of freezing and breaking.

Current building codes need a minimum amount of insulation in attics and walls. However, older homes were not adequately insulated, prompting several owners of such homes to resort to blow-in insulation. These are tiny pieces of material blown into the walls and above the ceiling through a long hose. Three materials are commonly used when making blow-in insulation, including cellulose, which is usually recycled from old newspapers, fiberglass, or rock wool. In most of its various forms, home insulation must be installed in ceiling cavities and bare walls before the drywall goes up, except for blow-in insulation. Blow-in insulation is the go-to product if you want to reinforce your existing insulation without having the troubles of a significant construction project. Installing the blow-in insulation in your attic is usually a straightforward process that does not require the expertise of an HVAC professional. Virtually anyone can do it. The process involves cutting 2-inch holes in the middle and at the top of the wall. Stuff some newspapers into the hole and save the cutouts. Spray small amounts of foam insulation, then set the cutout back in position. When your foam sets, trim the protruding hardened material with a knife before taping over the cutout and finishing the patches with a joint compound. If done correctly, the holes will disappear completely.
