Spotlights in Kingspan insulation

[MGPD]

Any way around cutting big holes in the insulation?

Its in a loft ceiling in a cold roof.

If it is Kingspan, etc, you cannot do that. It will wreck the thermal properties and create cold spots all over the ceiling.
Moist air from the room will be drawn into the roof space where it will condense and rot the roof timbers.
If it a new construction the Building Regulations police will make you re-instate the insulation.



Time to find a proper, and effective method of lighting your room, perhaps

Yes.

Do not use lights which need holes cut in the insulation.

I was thinking more like LED spotlights perhaps?

The holes in the insulation wouldnt need to be larger than the spotlight because they run alot cooler.

Is that what the manufacturer's instructions state?

because they run a lot cooler.

But still HOT.

There is no more to be said.

Still holes though, aren't they.

As much as I love down lighters, even I would tell a customer that they are absoloutely the wrong fitting to try and use in this sort of ceiling construction.

There is simply no way you could ever install them which won't compromise the insulation values, and possibly even the integrity of the building structure.

Have you looked at surface mounted spots? A few of my customers who wanted downlights in their insulated vaulted ceiling have used these, and they were perfectly happy with the results. You can also fit them with LED lamps to keep your energy bills down.

Or you could use lights designed to light up room spaces, rather than ones designed to not do that.

Hang on, let me get the popcorn....

Downlighters are designed to light up room spaces.

 

[ban-all-sheds]

No - they are explicitly designed to not have the beam pattern needed for whole room illumination.

 

[RF Lighting]

A single spot isn't designed to light a room, but that's not what we are talking about. Several spots ARE desinged to light a room, and do so very well.

But that is precisely the problem, which you keep on admitting.


S E V E R A L


Anybody who designs a light so poor at lighting up room spaces and says "it's designed to light up room spaces if you use several of them" is a lying, cheating, incompetent ****.

Not one of the several is designed to light up a room. Using several is necessary because they are not fit for purpose.

I don't really see your problem with them BAS, if you don't like them, don't have them in your house.

In THIS instance they are not the correct light, in many other situations they work very well. Just because you need to have more than one doesn't make it a poorly designed light.

Are multi-lamp chandeliers badly designed? Or other (non spot) lights with more than one lamp all poorly designed too?

No they do not - if they did work well at lighting up rooms you wouldn't need lots of them

Just because you need to have more than one doesn't make it a poorly designed light.

It makes it designed to not be fit for the purpose of general room illumination.

They would be badly designed as lights for general room illumination if you needed 25 to light a lounge and kitchen.
