lath plaster

[gordy71]

Hi i have read the previous threads but im just looking for an answer as to whether its ok to install downlighters in lath plaster ceilings. I know it will be a pain from an installation aspect but i want to know if its ok from a fire hazard point. I will be replacing the existing ones with fire rated and there are no signs of smouldering. Thanks

as long as the fitting is designed for fitting on a normally flammable surface, then yes. usually 35W GU10 max instead of 50 though

Right...

Now I read this that you imply fire-rated fitting will reduce the risk of the light setting fire to the lath & plaster?

( If I have got me pants on me head again I appologise.. )

BUT..

1/ Fire rated fittings are to reduce the passage of smoke between living compartments.

2/ It is nothing to do with the light fitting setting fire to the surrounding building structure.

:C

Consider:-

Many down lights are fitted onto or into wardrobes, bathroom cabinets, kitchen wall units, mounted directed on/in wood or chipboard construction.

IF any fitting got so hot that it was likely to cause combustion of the immediate surrounding material then....

I guess it would be exceptionally dangerous!!!!

Think if the unsuspecting homeowner wanted to adjust the angle of an eyeball or do a bit of decorating near by and accidentally touch the fitting..

Whist may be a tad warm...

It wont be getting that hot..

Fire rated or NON fire rated..

You only need fire rated if you want to stop smoke from a fire in the room below getting through to a room above to rapidly!

If I have miss read you intentions then again sorry..

but that's how your question appears to me?

Lath & plaster...

Just need a good quality cutter...

and something to capture all the dust and carp that flies off!!

And as long as the ceiling is sound ( ie: in good condition ) If its not the laths move as you drill and the plaster starts to come away .

Best to warn the customer first .

Maybe it would be as well to get "F" rated downlighters

Yes thanks for your replies guys, i do realise fire rated is to prevent the spread of fire, maintain the fire barrier and not less likely to cause one.
