Different profile types (open or closed profiles) have different heating behaviour. Closed profiles heat up faster than open profiles with the same U/A factor. This is taken into account by the appropriate thickness of the insulation layer former.
In the case of small gaps, it can be assumed that the intumescent will bridge them by foaming in the event of fire. The surface in the gap should be coated as deep as possible. For larger gaps, the gap…
No maintenance is necessary. The top coat must be checked regularly to ensure that it is undamaged. Damage to the coating structure must be repaired professionally without delay. The manufacturer's instructions must be observed. The owner of the object is…
We recommend first removing loose dust or other dirt by hand or mechanically, for example by blowing, vacuuming or light brushing. However, care must be taken to ensure that the coating is not damaged. Further cleaning is product-dependent and must…
As mechanical damage can be largely ruled out, maintenance is not necessary as long as no water damage occurs.
In order to obtain the building authority approval for exterior intumescent materials, outdoor exposure of coated steel plates is required. After 2, 5 and 10 years, aged plates are officially tested again and the approval is then extended accordingly. The…
A general statement on this is not possible. The manufacturers provide information as to whether systems with or without top coat are permitted.
Component temperature not below + 5°C, maximum + 40°C Relative air humidity max. 80 Dew point distance during processing and drying ≥ 3 K Protect the coating from weathering (rain) until the entire coating is finished and fully cured! Ensure…
This required layer thickness depends on several factors. These include, among others: the profile factor (U/A factor), the type of profile (closed/open), the desired fire resistance duration, the product used (manufacturer-dependent and regulated by approval), the required standard (DIN, EN),…
The profile factor is defined as the ratio of the flamed circumference to the cross-sectional area of the profile. There are tables for the commonly used standardized profiles. Thin-walled profiles with a correspondingly large profile factor heat up more quickly…
