Preparation

Insulation boards or panels are attached to the external walls of the building using adhesive or mechanical fixings.

These insulation materials are typically made of materials like expanded polystyrene (EPS), mineral wool, or polyurethane foam.

Covering

Once the insulation is in place, a protective layer is applied over the insulation boards to shield them from weathering and damage. This layer can consist of a variety of materials, including renders, cladding, or decorative finishes.

Weatherproofing

The final step involves ensuring that the external insulation system is weatherproof and resistant to moisture.

This may include applying waterproof coatings, sealing joints and edges, and incorporating features to facilitate drainage and ventilation, ensuring the durability and effectiveness of the insulation system over time.
