Fire hoods on downlighters

[monkey5]

hi,

ive been asked to fit 6 mains downlighters in a bathroom, it has a flat roof so ceiling coming down for access than boarding back up after. havent got it down yet so not sure if theres insulation up there.

my question are

if there is insulation or not will firehoods be needed if downlighters are not fire rated?

do you normally fit fire hoods as standard when you fit downlighters and which ones do you normally use?

cheers wayne

Be careful what you fit. I personally would not use mains d/l in a bathroom even if they are IP rated but there again I don't use mains d/l apart from low energy ones. It is going to need to be insulated after ceiling comes down. Personally I use snaplite d/lights as they have a rubber backing and are not affected by insulation at all.

Generally you shouldnt need fire hoods or a fire rated downlight unless

1. Three storey house, loft conversion, duplex flats, apartments.

Also would not bother with fire hoods, just get fire rated downlights instead as much less hassle in fitting.

All depends if you want to comply with building regs or not.

thats what i was worried about, the lack of room in the void. ceiling coming down over weekend so will have a better idea then.

if there LV do they still need to be ip rated?

One note of caution fire rated downlights do not mean you can ignore the insulation above.

You will have to fit insulation trays or do what I do and move the insulation from around the fitting

Cheapskate that I am.

for any of the zones in the bathroom they will need to be ip rated.

Snaplite can go direct in insulation.

Snaplite can go direct in insulation.

which wholesalers do you get snaplight from? and what sort of price are they?

Excuse my thickness here, but I have a few thoughts to ponder.....

Are we saying Flat roof? so there is NO inhabitable rooms above the bathroom?

AND

no combustible materials stored in the void above the bathroom?

In which case IS the bathroom ceiling classed as a fire barrier ceiling?

or just a 'normal ceiling'?

So would fire rated fittings and/or hoods be required?

Fire hoods / fire rated fittings are generally to prevent the passage of fire between floors..

i.e. a fire on one floor getting through the ceiling to burn the floors above.

They are NOT there to prevent the light fitting setting fire to something!

(ceiling mounted light fittings are designed not to set fire to their surrounding structure, even non fire rated ones!)

e.g. Fire rated fittings are typically rated 30mins or 60mins as a barrier to the passage of fire to allow persons on the floor above to escape!

flat roof above bathroom, No one above needing to escape me thinks? ?:| :|

Thats exactly what i was thinking as well Specs.

If anyone wants to have a look then here is a link from esc which has useful info on downlighters and building regs/ fire safety. There is also a quick reference table in their for different types of properties and when you need to use fire rated DL's or hoods.

My thoughts are generally if you use fire rated ones they also prevent the passage of moisture and the other problem with flat roofs where is the heat that standard downlights produce going to go. Never mind I can always come and put things right when it goes wrong.

exactly right special, no room above. the house has been extended and the roof is flat. but im expecting to find insulation in void when i rip it down, so would that mean hoods/fire rated downlighters will be needed if there is. and neither will be if there isnt?

just a thought, if gu10 led bulbs were used would fire hoods be needed as they dont produce hardly any heat if any.

Probably not but will you get the light output you need?

is there a great difference in the light a led one gives out compared to a standard lamp? didnt really think of that.
