    Looking for covers for downlights that are airtight as we are doing airtightness and don't want to break the insulation where we have downlights.

    number of approches you can take here
    1 - don;t use downlighters !!
    2 - build out ply or plasterboxes above and make them as an airtight attachment above the plaster board (make sure your arch/engineer signs this off as being acceptable due to fire risks)
    3 - buy bespoke covers
    4 - create a drop ceiling this will allow you to run all your services inside the airtight envelope and has many advantages

    Thanks all, it's just for the bay windows. We have no downlights upstairs at all due to the membrane except the hall where we are doing a drop ceiling.
    If anyone has any brands of covers they would recommend please pm me.

    Use of 4 inch pipe and airtight tape to make down lights airtight is Genius!!!

    unless they are LED they will get hot so be carful and make sure any halogen type has proper cooling/air movement - check out the manufactures details on the fittings

    Hi there.
    If it's not too late for your project, may I respectfully suggest 5-6inch terracotta pots. They are large enough to accomodate the 'usual' size of downlighters, and they have a ready made hole for cable entry. Fixing is simply a matter of applying a small amount of silicone or similar around the perimeter, and a bonus is that they can withstand a large amount of heat from the lamp. Best is of course LED lamps. No heat. Best regards.
