This is the problem my builder has given me to solve. They are saying that as I won't opt for carpet (due to health reasons) the best soundproofing I can have over a ceiling with downlights is a floating timber floor (which will have a layer of rubber under it) google isolite downlight covers, these or other types of heatcans should not compromise insulation Re: Has anyone installed Insulation between floors? 9Aug 24, 2009 9:53 pm thanks mikemix - will speak to my sparky tomorrow! progress viewtopic.php?f=31&t=20401 sculptures viewtopic.php?f=36&t=26607 pole trouble viewtopic.php?f=3&t=25988 Re: Has anyone installed Insulation between floors? 10Aug 25, 2009 10:26 pm seeking solutions Would all this soundproofing be compromised with downlights on the ceiling below????

They are saying that as I won't opt for carpet (due to health reasons) the best soundproofing I can have over a ceiling with downlights is a floating timber floor (which will have a layer of rubber under it) You have probably talked yourself into downlights already - but downlights are about the most inefficient and wasteful lights you can have. Even worse than the light globe you have as your avatar. You say you aren't having carpet yet you are exposing yourself to the dust from ceiling insulation thru the necessary holes in your ceiling for downlights (thats after they are in, not the hole to install them). In addition they: Let in hot air in summer thru the gap in the fixture Let out warm air in winter thru the gap in the fixture Use 10X the power of CFLs for same room size Add heat load to airconditioning in summer. Compromise ceiling insulation (more heat in summer and loss of heating energy in winter Add a fire risk Are more expensive to buy and install. My 2 cents worth Johnnojack Re: Has anyone installed Insulation between floors? 11Aug 26, 2009 6:52 am Will downlights compromise the acoustic insulation? If you are worried about downlights reducing the sound attenuation, then stop worrying. The fact that you have a stairwell between the 2 floors will have a significantly bigger impact on sound transmission than downlights. If you are worried about the thermal characteristics of downlights, then use CFL downlights instead.

I was very impressed. They had installed normal ceiling batts I believe, before plaster was put up. I believe it was 12 kids....... We installed Bradford Soundscreen Rockwool Batts to our downstairs ceiling and most internal walls. We allowed a 30cm perimeter around any downlight as per guidelines. I highly recommend installing them, especially in a double storey. You can really notice the difference Happy at Home Re: Has anyone installed Insulation between floors? 15Aug 26, 2009 10:35 am House-To-Be Bam They had installed normal ceiling batts I believe, before plaster was put up. We installed Bradford Soundscreen Rockwool Batts to our downstairs ceiling and most internal walls. We allowed a 30cm perimeter around any downlight as per guidelines. I highly recommend installing them, especially in a double storey. You can really notice the difference can I please ask - what type of flooring you have on the second floor and how many downlights below? Our builder is concerned with the health aspects of rockwool - it was our initial choice under timber flooring. Now they are telling me to go floating floor due to rubber underlays for their acoustic value and not use rockwool. The other comment I got was that by the time we cut out holes for the downlights the acoustic value of the rockwool will be significantly reduced progress viewtopic.php?f=31&t=20401 sculptures viewtopic.php?f=36&t=26607 pole trouble viewtopic.php?f=3&t=25988 Re: Has anyone installed Insulation between floors? 16Aug 26, 2009 11:00 am seeking solutions can I please ask - what type of flooring you have on the second floor and how many downlights below?

The other comment I got was that by the time we cut out holes for the downlights the acoustic value of the rockwool will be significantly reduced Our flooring upstairs was yellow tongue particle board with a top range underlay and carpet on top. I rang Hutton Insulation in Thomastown, Melb 9469 3399 after reading the bradford website, we had decided on the rockwool batts and Hutton said it was the way to go. Rockwool is denser (?) easier to install and not as itchy as the glass or polyester ones. We did it ourselves over a weekend. They sit in the frame under the floor and then the plaster was put over it. We have 13 downlights in total downstairs. Five in the family room (which we don't use), three downlights over my kitchen bench and another one behind, two over the dining table, one in the powder room and one in a little hallway. The other rooms just have batten fix lights. I have three children who spend alot of time upstairs as that is where the playroom is and most weekends there are an extra few kids here. It certainly makes a difference with sound transfer. I've been into a house like mine without any soundscreen batts and you can hear the difference straight away. I did all our internal walls (except for one) as well Are you having a timber/floating floor upstairs?
