loft insulation and lights, advice needed

brig001

tododo and wonka, these seem to be for ceiling roses and junction boxes. They don't appear to suitable for sealing over lights (no maximum wattage for example). I would check with the manufacturer before using these.

brig001,

Loftcaps are suitable for sealing over lights. I fitted these 2 years ago in my loft (6 downlights) and my house hasn't burnt down (yet). I did indeed check with the manufacturer, and ensured they comply with building regulations.

More information is available on the manufacturer's website:

Thanks wonka, I had googled, but not found that web site. They do indeed say that they are suitable for all lamp types, so I stand corrected.

It does say: There should be a minimum gap of 20mm (3/4”) around the cover to avoid overheating the light fitting.Overheating may cause a rapid reduction in lamp life. Do not place insulation materials directly over the cover as this can result in overheating problems.

Then they show one covered in insulation! I probably wouldn't cover them up, just to be on the safe side.

Hmmm... where does it say that? In the FAQ? If it's the FAQ, I assume that's just a general guide to their fire hood products. Otherwise it would contradict itself, because that page does state that you can lay loft insulation directly over the loft cap.

In fact, that specific type of hood is sturdy for that specific reason!

Anyway, I've laid loft insulation over my loft caps.... so...... <shrug>

Sorry wonka, yes it is in the FAQ pdf. Number 19 at the top of page 8.
I was a bit surprised when I read that and saw the pictures.

I am pursuing this a bit because my mum has downlighters in her bathroom and hence bad condensation in the loft. I will recommend these to her but tell her to cut the insulation round them to be on the safe side.

I had a similar problem at home. After lots of tedious web searching, i came across a company called stormflame.

They had a specific product for my downlighters but when I mentioned laying loft insulation they pointed towards another product that a 'loft cover'.

This allowed me to lay my insulation straight over the top without needing to clear round the lights. :T

The response was quick as was the delivery of the goods.:D

Have a look on their website.
