Wish all my jobs were that straight forward
I wish mate lol .. never that easy
Very interesting video
just asking is that cable tray galvernised or stainless steel.
Is the batt bad to breeth
Bit messy but very good
do we need to apply the sealant for both side of the board or one side as shown in the video is enough?
Yes,Batt should be sealed from both sides
Does the intumescent mastic break down the resistance of the insulation of the cables?
It's a water based acrylic mastic,I highly doubt so mate.
Does the opening not need to be dry lined ? Like framed out ?
Spot on mate...has to be a "letterbox" ope and this clearly isn't a letterbox formed ope!!
How long would it last un butterd
maybe around 30 mins, but idk if there's still smoke protection.
actually I dont think there's any unbuttered batt in use anymore.
My company ( Fire Stop Middle East)
Single batt and mastic jast up 60 minutes only 😂,Reed factory details 😢
