Air Gap Insulation

We are professionals in this field

When the air gap in the house is empty, the heat is "stacked" upwards (usually into the attic) and the house cools down quickly. When the air gap is filled with glass wool, the air circulation is stopped, so the house stays warm longer.

Thanks to new technologies, filling air gaps is really easy and inexpensive and the results are pleasing. Filling even the smallest air gaps of 5 cm makes your home more comfortable.
Holes of 22 mm diameter are drilled at intervals in the masonry joints, through which loose wadding is blown into the air gap using a special nozzle. This is done with Knauf Supafil Cavity Wall 034 loose-fill wool, which is characterised by its extremely fine fibre. It fills the air gaps very well, significantly increases the resistance of the walls and is completely non-combustible. Knauf Supafil does not absorb or absorb moisture, does not allow cold air to penetrate, is evenly distributed and does not break into pieces. Moisture from inside the building will be transferred to the outside through the Knauf Supafil wool, thus preventing mold inside the building. In old buildings, it is necessary to fill the air gap before façade insulation work is carried out. Otherwise, façade insulation is meaningless. It will be more difficult and costly to repair later. In new construction, Knauf Supafil loose wadding is used to blow into the air gap between the masonry wall and the clinker bricks.

We carry out insulation work all year round.
