    About Opalis

    The objective of the Opalis website is to facilitate the reuse of materials in construction and renovation projects. To this end, Opalis is organised on the basis of different sections.

    • The site shows an overview of professional retailers who sell building materials coming from old dismantled buildings.  In addition to their reuse products, these operators often offer other services: dismantling and cleaning, tailor-made elements, specialised advice, etc. In many cases, calling on their expertise is the best way to achieve the reuse ambitions within a construction project. The services offered by each operator are shown in detail on the descriptive sheets.

    • Opalis also provides technical documentation on the most common construction products on the reuse market: their main characteristics, frequency of release, availability, indicative prices, etc.

    • A third part describes recent realizations in which reuse materials have been applied successfully and in an inspiring way.

    • The last section contains useful documents and links for visitors who want to gather additional information.
