Waterproofing and thermal insulation are critical for ensuring the longevity, safety, and comfort of structures. Proper insulation protects buildings from the harmful effects of water and moisture, reduces heat loss, and creates a healthier indoor environment.

Incorrect product selection or inadequate application can lead to issues such as water leakage, moisture and mold formation, and heat loss, negatively affecting both structural performance and living comfort. Over time, these problems may also weaken structural elements and pose risks in terms of seismic safety.

Frequently Asked Questions About Insulation

Why is waterproofing important?

Waterproofing protects structures from the harmful effects of water and moisture. It helps preserve structural strength by preventing corrosion in foundations and load-bearing elements. It also prevents water leakage, reduces moisture and mold formation, and contributes to a longer building lifespan and a healthier living environment.

What is the purpose of thermal insulation?

Thermal insulation reduces heat loss in buildings and improves energy efficiency. It limits heat loss in winter and heat gain in summer, creating more balanced and comfortable indoor environments. It also provides energy savings, reduces operating costs, and contributes to environmental sustainability.

What happens if insulation is not applied?

In buildings without proper insulation, problems such as water leakage, moisture, mold formation, and heat loss may occur. These issues can damage structural elements and negatively affect overall living comfort.

Why are drainage boards used?

Drainage boards help remove water from building surfaces, preventing moisture- and water-related damage. They are particularly used in foundation and basement applications to prevent water accumulation and protect insulation layers.

To maintain drainage performance under soil loads, the drainage board must have sufficient strength and be manufactured with high quality. Insufficient durability may lead to deformation over time and loss of drainage performance.

They are widely used in foundations, basements, underground structures, tunnels, and green roof systems.

What determines insulation costs?

Insulation costs vary depending on the type of product, application area, system details, and project requirements. Choosing the right product and system directly affects the balance between cost and performance.
