Browse Forums Heating, Cooling & Insulation 1 Jan 30, 2011 6:26 am What is the easiest way to install ceiling insulation in a new house I am building. I have a pitched colourbond roof, but the central heating/cooling ductwork fills up a lot of the under roof space, with a lot of ductwork resting on the bottom chord of the 900mm spaced roof trusses. The battens for the plasterboard ceiling are not yet installed. Blow in insulation after the ceiling plasterboard is in place, or try to install batts from underneath once the ceiling plasterboard battens have been installed, but before plasterboard fixed in ????? Re: ADVICE WITH INSTALLING CEILING INSULATION PLEASE. 2Jan 31, 2011 9:52 am After a bit of investigation, blow in insulation is cheaper and generally gives a much higher R rating than quoted. I wasn't a fan but after looking at the difference in price we chose blow in. Re: ADVICE WITH INSTALLING CEILING INSULATION PLEASE. 4Feb 03, 2011 3:25 pm I have been a part of the insulation industry for over 8 years and in my experience you really want to avoid blow-in insulation, especially cellulose. We have had many clients who have had serious house fires due to the cellulose in the roof catching fire. These are usually due to halogen downlights igniting the cellulose. I would always recommend using batt insulation as the R-value will be maintained over the life time of the house. (no packing down over time). We most commonly install glasswool batts from underneath, once the battens have been installed. It is the preferred method of most builders out there today. Just make sure you get the correct width batts. If your trusses are 600mm spaced, then you will need to get 580mm wide batts. Otherwise if you have 900mm spacings, you will need to install 2 x 430mm batts. hope this helps Re: ADVICE WITH INSTALLING CEILING INSULATION PLEASE. 5Feb 03, 2011 9:04 pm just rite I have been a part of the insulation industry for over 8 years and in my experience you really want to avoid blow-in insulation, especially cellulose.

Since the farther inlaw use to install blow in cellouse he would always say how much the batts have collapsed. and he only had one incident with fire and that was because they were supplied the wrong material with out the fire retardent in it. personally i would hate getting up into a roof with glass batts. I also have blow in insulation in my roof and i find it to be great easy to move out of the way if needing to work in the roof Hello - we were hoping to apply laminate click lock panels to our concrete ceiling, but not too sure how to go about attaching the panels to the concrete.
