I changed 10 old big downlights last week & the fitter of them in the 1980s thought about fire hoods & keeping the loft insulation off them, I now have 6 terracotta plant pots & 4 brown & beige pudding bowls!
Which Fireproof Downlights or Hoods are best to maintain insulation levels and not pass airflow through the Downlights fitting or hood ? This witches hats have lots of holes in them and will pass draft airflow.
I can't believe we are discussing the testing of manufactured joists they have been widely been used in mainstream house building for the last 15 years and fire-rated downlights have been fitted for at least 10. Why so behind?
Been building with engineered timber in Scotland for around 30 years! Its interesting that only since English House builders started using the i joist shown in the video that regulations have changed. The only place you'll see double block wall houses in Scotland is pre 1990's construction or if they were built by English builders.
Apart from playing the "What type of ceiling construction" quiz, it sounds like a remote camera/light to examine the construction is an essential tool now. Have you any videos on options?
Any idea what we’re supposed to be using for a fire barrier with a ceiling mounted or inline fan? I’ve used plasterboard to box it, but if there’s a better product/method....
A good question - lots of people use plasterboard and we’ve heard rumours of intumescent blankets - we will explore this further and see if we can get some answers
Hi guys i am just wondering What about the single insulated cables and unenclosed connections above the 50mm 1st fittings you installed lights surely this does not comply with Bs7671 Thanks Neil
@@jamesmoon5632 Most drivers have 300mm from the driver to the fitting so it could be outside the hood the only problem that I can see is if you need to get to that driver for replacement or testing can you get to it?
Does the fire hood metal retainer(s) that you snipped remain visible once the downlight is fitted? Only I noticed at 4:53 the retainer is on show. How can the downlight possibly be a true flush fitting if the strip of the fire hood is on the plasterboard surface? You'd have to make an identation in the ceiling.
Most new builds have air handling ventilation units in the lofts which have air vents in the ceilings of all rooms with usually a boost switch for the kitchen and bathrooms, it extracts the stale air which goes through the air handling unit to filter it and circulates as cleaner air, its supposed to prevent damp in buildings as well. The filters need changing every so often.
@@paultipton743 What have AHU filters got to do with fire rating a 4” hole in the ceiling that has a bathroom extractor fan going through it? The question was how can you put a hood over a fan? Unless I’m missing something?
@@sam04019491 it was a reply to another person commenting on extractor fans. The post was 4 months ago I dont the full conversation, it looks like the conversation for the fans was referring to a different you tube post.
Not a lot of space for junction box!! All will be very squashed! In the age of technology it’s hard to believe that we still have to put up with this carry on!
A stanley blade can be used to scratch a little channel into the plaster for the metal rods to bed into, having said that im sure there must be a less fidley way to fire proof light fittings
I thought that the hole idea of LED lights was because they don’t get hot or heat up, so why a fire hood? If LEDs do get hot then why bother with them just stick with standard pendants don’t have to worry about fire proofing then
I haven't fitted down lights for a long time, probably 12+ years or more. I can remember the Witches hats as they were called back then being used, I'm surprised they are still being used as I would of expected the downlights to be more fire rated nowadays
LEDs down lights Don’t get hot, So fire hoods are not required, also if the light fitting is fire rated the fire hoods are a wast of time and effort, they were required when photoflood down lights were the norm. What is the hottest part of a house ? Or the coldest? Summer time temperature outside is 80c in your loft it’ll be nearer 200 c but we don’t see lofts bursting into flames , LED down lights are not going to produce enough heat to course a fire , this is just health and safety gone made
The firewood is to maintain integrity of the fire barrier. It has nothing to do with fitting temperature.

@@kieranhall1998 the material is utterly irrelevant, if the fitting falls out during a fire in the room below the smoke will go straight through those holes in the hood into the floor void!
@@stuartcraigon2003 Did you actually research intumescent materials before wiritng this? the holes will seal before the fire escapes the hood and sets fire to the rest of the materials in the floor celing or whatever. Also will quench the fire at least somewhat as it does not sustain fire
@@stuartcraigon2003 Lol. The intumescent material doesnt need fire to swell up, it is a heat reaction so whenever there is enough heat it will swell up, therefore it swells up before there is fire everywhere in the ceiling cavity to cause the house to burn at a much faster rate. This is what these products are for. Having them seal to stop smoke into the ceiling cavity because smoke kills in fires more than flames is irrelevant and a ridiculous argument as the smoke would not do anything if it is just filling up a ceiling cavity.

Could you please answer as I am fitting some fire rated downlight from quickwire in the on suite. These will be going into the insulation.
Do these still work if the ceiling is double boarded? Also be very difficult to change a driver if it was to fail.
You made light work of that 💡👍
Thanks for the illuminating comment 🔦
They look a lot better to fit than the flimsy tent hoods 👍👍
grrat video., fire hoods are the future ! no worries about the type of downlights then . 👍
What about if there is insulations in between ? Will it still practical?
Thanks Gary!!!
Insulation in between shouldn't be a problem.
Sod it I'm fitting a battern fitting! Lol.
What about Light gauge steel joists does the NHBC have an issue with these?
Great video efixx team 👍

Um, The wire between the ceiling and the bezel is an issue.
Hi guys i am just wondering What about the single insulated cables and unenclosed connections above the 50mm 1st fittings you installed lights surely this does not comply with Bs7671

The wiring connected to the LED fixture is from an LED driver with SELV output - hence single insulated cable.
@@efixx is the driver inside the hood? That would overheat

You'd have to make an identation in the ceiling.
It depends upon the design of the fitting, we found it possible to press the cut ends in to the board surface and achieve a flush finish.
The whole thing is complete shite!!
What about 4” toilet fans I’ve installed a sleave over the fan not sure if its correct but most new builds I’ve seen dont have them..

The junction box doesn’t need to be enclosed within the fire hood.
@@efixx that’s going to be tricky enough to take back out a faulty driver with the hat as well! I don’t know, I think we’re going backwards here!

Its abit of an waste of time when you can get fire rated downlights for led or halogen 🤦♂️
You cant get fire rated versions of popular architect and designer specified downlights (e.g iguzzini laser blade) or larger downlights.
Errrrr it has holes in ???
