Browse Forums Heating, Cooling & Insulation 1 Jun 10, 2012 10:40 am I am building a house on the central coast nsw with a local project builder. At the moment we are renting a 2 storey house which is similar to the one we are building and with all the crap weather we've had lately I've noticed how cold the flooring is. Now the question-- is it worth the expense of between floor insulation or not?? we already will be getting roof and external wall insulation.Is it safe, is it effective, I have seen it advertised recently but cant remember the company name , no luck with google as yet!! Any suggestions would be very welcome thanks syd Re: between floor insulation? 2Jun 10, 2012 11:26 am Between floor insulation is more about noise than heat.

Re: between floor insulation? 3Jun 12, 2012 8:14 am Insulating the floor space between levels can add to the comfort levels in some instances. For example in a dwelling where a primary area in the lower area is to be heated - such as a living or family area - then retarding heat 'escaping' through the 'ceiling' to upstairs areas such as bedrooms where a lower comfort level is required, then insulating may be beneficial. There are aspects that come into play, such as is the lower area capable of being isolated from the stairwell which will funnel the heated air upstairs in any case. The 'Thermal Assessor' who provided the initial rating can input the additional insulation levels to determine the benefit gained in heating and cooling to the particular area in mj/m2. At the end of the day - as a general rule - the greatest advantage will come from the insulation levels to the envelope of the dwelling. As mentioned previously noise reduction can be a main benefit of insulating, but if this is the reason for insulating then 'acoustic' insulation should be looked at together with additional measures including 'isolating' transferrance of noise through the floor joist members.

Re: between floor insulation? 4Jun 13, 2012 10:55 am thanks heaps for replies --The main reason we are concerned is that the bedroom 1 is located directly above double garage--the house we are building is pretty close to a dual occupancy living area and 2 bed downstairs for the son and 2 bed kitchen living areas upstairs for me and the boss, most rooms have been designed to be able to be shut off for better heating and cooling but we hadn't considered between floor issues except for stairwell untill now. We are not too far away from gyprock being installed so a decision will need to made soon. thank you everyone Re: between floor insulation? 5Jun 13, 2012 11:11 am Any rooms above a garage area should definitely be insulated.

I wanted to put under the ground floor sub floor also( suspended timber floors) as it will be an open void space under but the builder talked me out of it. I still may get him to do it as we are having mainly floorboards layer on 19mm particle board so don't want this to be the weakest link when it comes to insulation.

If there is plenty of access height & the budget is tight it is an item that can be retrofitted at a later date - unlike wall or between upper & lower storeys. A rigid type insulation such as extruded polystyrene is a good selection with an air space to the underside of the flooring. A wool type product needs to be well sealed off to prevent vermin such as mice or rats nesting.
