The simple answer is yes; our installation details can be used on different manufacturers’ wall systems, provided they meet the caveats below.
As per BS EN 1366-3:2021, the fire-resistance test standard for service penetrations, the following rules are stated:
13.3.2.1
Test results obtained with the standard double-sided flexible wall construction in accordance with 7.2.2.1.2.1 may be used for all double-sided flexible wall constructions (with and without insulation) of the same or higher fire resistance classification as per EN 15301-2. This is with lining made of Gypsum boards as per EN 520, or Calcium Silicate boards based on an ETA for the application as lining of flexible walls, if their construction is in accordance with the rules given in Table 5.
To fully understand the BS EN 1366-3:2021 rules for the interchangeability of supporting constructions, please refer to our separate knowledge hub piece here.
However, the general rules from Table 5 are as follows, meaning that the flexible walls we primarily test will also cover:
- Flexible wall constructions as tested;
- Flexible wall constructions with the same or higher number of board layers of the same overall lining thickness on each side of the wall and the same insulation as tested;
- Flexible wall constructions with an aperture framing with fewer board layers but the same or higher overall lining thickness as tested, with insulation of any type;
- Flexible wall construction with timber studs, constructed with at least one layer of boards, no part of the penetration seal closer than 100mm to any stud or nogging piece, the cavity closed between the penetration seal and the stud/nogging piece with a minimum 100mm of insulation of class A1 or A2 in accordance with EN 13501-1;
- Rigid wall constructions in accordance with 13.3.2.4.
