Dry-Lining Boxes

[Bez]

Do we, or do we not need to use fire rated boxes in stud walls, (been having a DISCUSSION with a mate), and if so, why do they still sell the normal ones?

Cheers

I've never used a fire rated box, but then again I've never (knowingly!) installed a box in a fire wall.

may be for walls separating 2 flats?

Not all stud walls are fire barriers but you do need to find out from the designer of the building whether or not the sud wall is a fire barrier if it is then you need to use the fire rated ones.

This is the best answer you could get.

Well done nicks electrix.

You have to be fully aware of the regulations, and if working to any plans you will get the information you need, as to fire protection and or sound.

If you are the designer you will have to do all the risk assessments to establish, along with building regulations if the stud wall, is, or would, require any special attention, as regards sound, and fire.

Ah, now it makes sense. I was under the impression that if you broke the integrity of any plasterboard partition, then you had to re-instate it with fire/acoustic rated boxes.

Many thanks for clearing that up. I don't know how it would work out on older premises though, I suppose if in doubt, fit them, or does it only apply to new builds?

You will have a responsibilty to maintain the acoustic integrity, if the partition requires this. Its not always just fire regulations.

I always liase with the building reg enforcement officers, if they want it, I provide it, that way we never get into conflict, I do advise them of the regulations, and most do take my reccomendations on board.

However I have learned to listen to them as well, and I always give them what they want.

This way I have never had any complaints, and as a result I have done work in their own homes, because they trust my work.

I just wish they could reccomend me in an official capacity, but alas the rules will not let them, poo rules if you ask me

I would have thought that you use standard dry lining boxes in the rooms of your typical house (subject to building regs). The fire rated boxes I assumed would be for new timber framed houses - ie timber and a shed load of kingspan insulation and probably 2 overlapping layers of plasterboard for the wall between 2 seperate properties of semi detached type.

what about fire rated Sockets and Light switches to fit onto these fire rate dry-line boxes!!!

 

[mojorebel]

and whatabout using fp cabling inside the firewalls?

I think the object of a fire rated box is to maintain the fire-proofing of the wall to it's given rating, ie 15 mins, 30mins, etc. Once the fire is through the wall I thing the cable is the least of your worries:O
