Terraces are the parts of buildings most exposed to weather conditions. Therefore, choosing the right materials for both thermal and waterproofing is crucial for the building's lifespan and comfort. Using the wrong materials can quickly lead to water leaks, heat loss, and structural issues. For thermal insulation, XPS or EPS boards are commonly preferred, while waterproofing is typically achieved using bituminous membranes, polyurethane coatings, or liquid waterproofing products. Ensuring the surface is smooth, clean, and dry before application greatly affects the success of the insulation. When performed by a professional team with materials suitable for the climate and building type, your terrace will remain problem-free for many years.
