By using acoustic floor insulation you block air cavities between floors that enable ambient sound to travel.

Insulation between floors in house. Acoustic insulation is very effective at reducing airborne noise. Foam board insulation is easy to use and is a great diy way to add some insulation. The higher the r value the better the thermal performance of the insulation. However there are certain scenarios and reasons like sound proofing to insulate between floors.

Sometimes buildings are construction with first floor eaves and soffits. The table below shows what levels of insulation are cost effective for different climates and locations in the home. Because they have a high r value and can be used nearly anywhere in your home foam board insulation is one of the most common types of insulation.

Sound insulation between two levels of a house can help to create a quieter home and contain sound to its designated area.

Some types of thicker foam board insulation are available but they may need to be special ordered. This will also increase thermal insulation for the room above and below making them more comfortable to be in and quieter too. Don t compress the insulation when installing it but allow it to expand to fill the cavity. You also reduce the space in which joists and floorboards can vibrate which reduces vibration noise.
