Russdl Posted April 20, 2020 Share Posted April 20, 2020 How do I find out if I need fire rated terminals for my MVHR ducts. Is there some guidance written in stone or is it down to the whims of Building Control (who aren't answering my questions at the moment). Do you have to have them in the kitchen for example but not bathrooms? Any guidance would be much appreciated. Link to comment Share on other sites More sharing options...
Jeremy Harris Posted April 20, 2020 Share Posted April 20, 2020 When I asked about this I was told that was that there wasn't a requirement for them in a two storey dwelling. I have a feeling there's a thread here somewhere discussing MVHR and fire risk that may have covered this, and also whether or not there needed to be a "fire switch" to turn the MVHR off in the event of fire (to reduce the potential for it to supply fresh air to a fire). I can't seem to find it, though, perhaps it was embedded in the middle of some unrelated thread. Link to comment Share on other sites More sharing options...
Russdl Posted April 20, 2020 Author Share Posted April 20, 2020 I think I found that particular thread but it didn't think it answered my specific question. We are two storey, however, our loft is fully open to below on one side and will be accessed by a permanent staircase though it will only be used for storage, that may well put us in a grey area.
