Which technical terms are used?
The most important terms in this handbook — briefly explained.
| Term | Explanation |
|---|---|
| Thermoreflection | Reflection of radiant heat (solar/infrared radiation) at the coating surface. |
| TSR (Total Solar Reflectance) | Proportion of reflected solar radiation across the entire spectrum. |
| Ceramic nanospheres | Tiny, hollow spheres of glass ceramic in the functional layer; they reduce heat conduction. |
| Glass ceramic | A material produced as glass and made partly crystalline through controlled crystallisation. |
| Knudsen effect | Greatly reduced heat conduction in cavities smaller than the mean free path of the gas molecules. |
| Primer | Base layer (ECB BASIC B) that ensures the adhesion of the following layers. |
| Functional layer | Thermoreflective intermediate layer (BUILD) with the insulating effect. |
| Top coat | Weather- and UV-resistant finishing layer (ECO OUTSIDE). |
| Adhesive tensile strength | Force per area with which the coating adheres to the substrate (N/mm² or MPa). |
| Water-vapour permeability (V class) | Measure of the diffusion of water vapour through the coating (EN 15824). For the overall system build-up: class V2. |
| Water absorption (W class) | Measure of the absorption of liquid water (EN 15824, class W3). |
| Binder | Film former of the coating — here an aqueous acrylic resin dispersion. |
| Airless | High-pressure spraying process without atomising air. |
| Maturing time | Time until the applied layer is fully cured. |
| EN 15824 | Harmonised European standard for organic-based external and internal renders. |
| AVCP | Assessment and Verification of Constancy of Performance (here system 3). |
| Declaration of Performance (DoP) | Formal declaration of the product performance; basis of the CE marking. |
| CE marking | Conformity mark under the EU Construction Products Regulation (EU) 2024/3110. |
