The integrity of fire-stopping systems is a hot topic due to recent catastrophic fires in high-rise buildings. Therefore, testing our fire-stopping systems to the highest standards possible is always a top priority. Walraven works with some of the best testing laboratories in Europe, such as Warrington (BE), MPAs (DE), and Efectis (NL). At these laboratories, they understand which issues can have an impact, such as pipe movement or smoke sealing. These kinds of problems do not need to be tested, but we believe they’re a crucial part of a firestop’s overall effectiveness. By cooperating with these laboratories, we get valuable professional opinions on the performance of our product in those non-tested yet realistic situations.
In addition to working with third-party organisations, Walraven also has its own testing facility in the Netherlands. We believe in testing products for real-life situations, not simply meeting test conditions. Testing a wide range of scenarios helps ensure that our products do their job. Because of our in-depth understanding of our products’ behaviour, we push their performance. And with our in-house testing, we can respond quickly to market needs and changing requirements.
