Though the technical properties of CLT are highly consistent, the visual aspect can vary significantly. Where a project requires a high standard visual quality, lamellas are selected with the best aesthetic properties and unwanted defects are eliminated.
Xilonor offers three visual qualities:
| CLT Visual Quality Options | |
| N | Non-Visual |
| I | Industrial |
| V | Visual |
Non-Visual: Suitable where the timber is destined to be concealed behind other materials or where natural anomalies are tolerated.
Industrial: Suitable where the structure will remain visible but with limited aesthetic impact or where appearance is of lower priority as may be the case in commercial or industrial settings.
Visual: Suitable where the timber will remain visible and forms part of the aesthetics of the structure thus requiring a high-quality finish, as may be the case in residential dwellings, schools, or offices.
Xilonor CLT visual quality is defined with the following configurations:
