It has been known for some time that untreated (!) wood has a predictable burning behavior. However, you must have initial values and then also know which parameter has which (negative) impact. Based on this incredibly large amount of data, you can create a calculation model that allows you to accurately calculate specific values such as FIGRA and THR.
An intelligent, non-flammable profile is integrated on the two sides. By integrating them into the sides, this is minimally visible and you have a identical fire reaction class on the front and rear. After all, it is now at least as plausible that the fire starts on the inside (electric cars, etc.) than on the outside.
The non-flammable strips ensure that in this example at least 20% less flammable surface is present. At the same time, the positioning and width have been calculated in such a way that an optimal fire barrier form and it will be very difficult for the flame to spread to the back. The flammable surface of the slats is thus halved approximately from 80% to 40%. Such a decrease in flammable surface area obviously also has a strong impact on the FIGRA and THR. The fire will therefore not spread to the other side.
The intelligent aluminum extrusion profile will optimally conduct the heat away from the flame. Where the flame is not directly present on the profile, the aluminum will also be able to emit heat or in other words; cooling.
The profile is also full of several small details that have a big impact, here are some examples:
The first tests have shown that the theory corresponds to reality.
| Lamella thickness | 40 – 70mm |
| Slat width | 90 – 360mm |
| Heart to heart distance | 20 – 150 cm |
| Therapy | No |
