@RockyB213@OneBadDude_ Water doesn’t actually increase the volume. It takes up the space between particles, thus, the same volume of concrete mix is required.
@MhehedZherting@murphy31bTwist@BLAIMGame You’re struggling though so I’m going to help you out as this amuses me:
1) Not all doors in schools are fire doors.
2) Those that are, have no intumescent material at the bottom, hence the permissible tolerance to increase the free area.
😊
@MhehedZherting@murphy31bTwist@BLAIMGame You’re clearly passionate about the structural integrity of fire doors in Scottish classrooms though, & I can respect that 😂.
@MhehedZherting@murphy31bTwist@BLAIMGame What part of ‘small as practical’ do you not understand? 😂
This is brilliant though. As I didn’t realise you specifically meant that ~4-10mm undercut of fire doors was what you find particularly moronic in all of this.
Too funny 😂
@MhehedZherting@murphy31bTwist@BLAIMGame Undercutting doors improves air flow & thus ventilation. The original assertion was that this was a ‘moronic covid rule’.
It wasn’t.
@MhehedZherting@murphy31bTwist@BLAIMGame Yep.
Air transfer via undercutting of doors (or air transfer grilles) is already a recognised strategy in building regulations. This merely informs us that pre-existing buildings clearly weren’t satisfying Part F.
