Cavity Wall Insulation with EPS Beads in Hamme

For this home in Hamme, the existing cavity walls were retrofitted with insulation to improve the thermal performance of the property. Because the cavity was accessible and suitable for insulation, the work could be completed without major changes to the interior or exterior of the home.

Small openings were created at carefully selected points in the mortar joints of the façade. EPS beads were then injected through these openings to fill the available cavity space as evenly as possible.

Insulating the cavity helps reduce heat loss through the exterior walls. As a result, the interior wall surfaces can feel more comfortable and the overall indoor climate can improve, especially during colder periods.

One of the main advantages of this method is that the installation can be carried out relatively quickly while leaving the façade largely unchanged. Once the insulation work was completed, the drill holes were carefully sealed to preserve the original appearance of the exterior.

This project in Hamme demonstrates how an existing home can be thermally upgraded in a practical way without the need for extensive renovation work.
