Calculation of fire resistance of exterior wall

[TommieK]

Can anyone help me calculate the fire resistance for an exterior wall?

The goal is to meet ei60

From the outside:

22mm lockpanel
spikläkt
45mm rockwool
13mm asfaboard
50mm glasull
25mm brädor
3x5 regelvägg med spånisolering
19mm spåntat virke
13mm gips

Best regards

Here you can calculate if you feel like it, but it's probably completely unnecessary. Your wall always meets ei30, which is the usual requirement.

forgot to mention that it is ei60 I want to fulfill.

I guess that a layer of gypsum is needed on the framework for it to be approved. However, I haven't done the calculations, but I got help from Isover with the construction of my facade, which is rated EI60. I have exterior cladding, air gap, 80mm facade board, gypsum, plank framework.

Call your fire station and talk to the engineer. That way you'll get the right answer.

called there but seemed like it wasn't something they were interested in helping with. I'll have to look further.

Call the building permit office at the municipality and ask who they usually hire. Otherwise, call several fire stations and talk to a fire engineer. Villaägarna could be an option, technical expert advice. The annual fee is about 400.00
