AIR GAP FILLING bulk wool

• In order to effectively reduce heating costs, in buildings of old or new construction with an air gap, it is recommended to start with the insulation of the air gap.

• Air gap filling with bulk wool can also improve sound insulation, reducing noise levels from the street or neighbors.

• Without the process of warming the walls into the air gap, the wall is exposed to cold and moist air, because the warm air in the partition rises to the top, making it possible for cold air to enter the bottom of the wall.

• In order to stop the circulation of warm and cold air in the partition, it is necessary to fill the air gap. "KNAUF Supafil Cavity Wall" is perfect for this, loose sprayed insulating wool is injected through drilled holes, in the seams of the masonry wall, which are filled with masonry mixture after the work has been completed.

• The price of air gap insulation directly depends on the width of the air gap, as the need for insulation material is calculated based on this.
