Batting material in old house attic.

To insulate an attic get some batting made out of mineral wool fiberglass or recycled foam. The insulation materials used in older houses are not as effective in keeping heat in as the new ones. Because the simplest and cheapest way to insulate an attic is to add material to the floor. In a cooling climate a good blanket of attic insulation helps keep the house cooler and reduces the load on air conditioning equipment.

The insulation must meet doe standards. The format of house insulation you need depends on where you put it and if you need to control. Stop using your attic for storage. Cold areas require a higher r value like an r 49.

The answer to making an old house inhabitable is insulation. The big disadvantage with spray foam is cost. Additionally purchase some loose fill insulation to insulate corners and angles where the batting won t fit. Typically houses in warm weather states should have an r 38 insulation in the attic whereas houses in cold climates should have r 49.

There are other materials and systems that you can use to insulate your attic. Increase your r value by layering insulation. Even if you bought the house with insulation already installed into it it s best to double check. Layer more insulation over the old for more effectiveness.

If you live in a warm climate you require a lower r value. Plan to pull up the flooring and layer new insulation on top of the old. It s generally 3 to 4 times what you ll pay for blown cellulose or fiberglass.
