insulation

maestroamado

Does anyone have advise on the type of insulation to use where there is a tiled suspended ceiling. The ceiling tiles and lights need to be replaced and looking to put insulation... Rockwool seems to be an option ...

Any advise appreciated...

What's above the ceiling tiles, is it concrete or joists, what kind of access is available

See forum charter, Don’t bump threads.

With the limited info provided, a suspended ceiling suggests it may be a commercial space, therefore mineral wool ie ‘rock wool’ or equal type product that is fire resistant/retardant, should be used.

Bryan, The reason i bump thread is there is a problem as each time i create a thread it does not show in "my threads" when i refresh it shows... why is this...

Topic... This is void of nearly a metre above the celing... the structure ceiling is industrial standard concrete slab... The lights are 1200x600mm (4x2ft) and need to be replaced... we are hoping the light space be big enough for access as it is just the tiles need to be replaced...

BryanF

Definitely only use mineral wool (products such as ‘rock wool’) or equal. Do not use anything with the word ‘poly’ in n it. Be careful to only use insulation that is fire retardant.

I don't think you've given nearly enough information for somebody to answer.

Type of building.

What is above, external space or another unit. If external, is the roof insulated?

Purpose of insulation, etc. I would expect commercial ceilings more often to be acoustic rather than thermal etc

Any advise on your bump comment as i did explain why and this problem each time i create a post...

maestroamado

I have no more info than you do. But don’t see the need to bump threads.

What's the purpose of the insulation?

maestroamado

https://www.boards.ie/discussion/comment/118503094#Comment_118503094

principal purpose heat retention...

I told you the need... thread not show and when refresh it does... not point in dishing out rules if query cannot be resolved... this has happened a few times so i am hoping you can resolve... i think you are a boss....

Depending on what is the primary or dominant mechanism of heat loss of the heated space, you may be underwhelmed at the result of what you propose.

maestroamado

you make something that is very simple complicated... i have a couple of options that i now know will work...

Apologies, I thought you were serious about reducing your heat loss... My bad... Good night

Threads you have started appear in "My Discussions". Under your profile in the corner or this link https://www.boards.ie/discussions/mine

"My threads" is the threads you have bookmarked (treads are auto bookmarked when you reply). It didn't show there because you didn't bookmark or reply to it. To add it to that list, you just need to click the bookmark in the top right corner. Not do a dummy repy.

It's really not that simple. You are insulating the ceiling when it might not even be the ceiling losing heat.

A few rolls of rockwoll is a cheap addition. But make cheap changes, expect cheap results. But not sure why you are asking for advice when you know it all already.

maestroamado

Thanks for advise in thread, I will try as it's only since this new format I have problem.

I am not insulting, it's just a quib.... l know where the heat is going to the reason I know fix option is I talked to installer the other day. Actually he mentioned rockwoll as option which I thought be unsuitable...

I asked a question here... most of the replies i got were more questions... i made one phone call and sorted... says a lot about what going on here...

The reason you got more questions was due to the lack of information. You mentioned a ceiling in a commercial space. Without even mentioned if it was acoustic ir thermal insulation you were asking about.

FWIW, I mainly work in the commercial building design. Acoustic is way way more common than thermal - so the questions where in regards as to whether you were looking at the right insulation, in the right place.

That stuff looks good... i wonder would it be too heavy for suspended ceiling...

Why would you insulate a suspended ceiling for?

maestroamado

https://www.boards.ie/discussion/comment/118901312#Comment_118901312

seems like a silly question but since you ask principally to retain heat... it may also help with acoustics i don't know... there is a void of about a metre...

There are also loads of walls which extend beyond the suspended ceiling, which will reduce the impact of quilt insulation there.

Google thermal bridges and see what the issue is

maestroamado

https://www.boards.ie/discussion/comment/118901769#Comment_118901769

I am assuming you mean load-bearing walls... thanks i will google bridges now...

You should not be insulating the suspended ceiling as previously advised to you.

The thermal layer is in the ceiling above it. You’ll have holes and penetrations in the suspended ceiling for detectors, light fixtures etc.

Silly reason tbh.

maestroamado

https://www.boards.ie/discussion/comment/118901926#Comment_118901926

I do not remember being told before not to insulate and the ceiling guy said it can be done... what thermal layer are you talking of..,

Silly season... i always thought a forum was to get info we do not know... you seem to think its silly to ask and your a boss...

I would expect moderate language from moderator...

I’m not a Mod in here.

You stated my question was silly so don’t get offended when told your reasons are silly.

You started this thread in January. You posted that you got sorted yet you haven’t done it yet.

You also started another thread for insulation on a concrete floor under carpet.

To me, you have been illadvised by somebody in the real world, maybe been taking advantage of as what you are trying to do makes no technical, construction or thermal sense.

You will have to read back as that's not what i said in Jan about insulating a suspended ceiling... the reason nothing has happened is i thought the place becoming vacant end Feb so i have to wait... i had kinda decided a course of action... it was not me who re-opened this thread a few days ago...

If you took the time to look you would have seen that the thread was bumped by a new account with their first and only post, no doubt with the intentions of promoting a product they have a vested interest in. You were first out of the traps after that. As I said before your attitude is all wrong.

No, don't assume I mean load bearing walls. A thermal bridge does not need to be load bearing

To be honest this is outside my comfort zone which is why i am asking around... i would have to check back what was said here but i did contact a guy who installed suspended ceiling and when he said it was not a problem i forgot until someone mentioned here a few days ago... Then there was the delay but i am still hoping to do in coming months... It is basically a big room 80+ sq metres... 900 sq ft with a concrete ceiling... there is a void pf about 1 metre above suspended ceiling... I am sorry if you read this before but i welcome advise and best option...
