Bruce Re: Hebal flooring 5Dec 24, 2016 10:29 am We're strongly considering Hebel flooring for our upcoming build too, so I'm also interested in any experiences. About getting hot in summer, Hebel has much more thermal mass than yellow tongue (but not as much as regular concrete, e.g. suspended slab) and is also an insulator. Thermal mass = thermal inertia. If you let the whole house get hot then it'll take a bit more effort to cool it down again - the same as for any well-insulated modern house with thermal mass (e.g. concrete slab). The 'trick' is to use the additional thermal mass to prevent the house getting that hot in the first place. Re: Hebal flooring 6Sep 19, 2017 12:33 am I frankly doubt that most people expose the second floor thermal mass a lot as generally you would put either carpets or hardwood to your first floor bedrooms and both materials are good insulators. My understanding is that mostly people use Hebel PowerFloors for their acoustic and rigidity properties. Re: Hebal flooring 7Sep 19, 2017 12:36 am Gtree Hey Nom, does ur hebel home get hot in summer? I got told by a builder that hebel blocks trap heat after a few hot days. Thanks Alan You would need to ventilate your rooms during night time in order to cool down thermal mass. Also, if Hebel is covered with insulating floor coverings (such as carpets or hardwood), your rooms will be much less exposed to the stored thermal energy.

My understanding is that mostly people use Hebel PowerFloors for their acoustic and rigidity properties. Yeah, we're building a passive solar house, and are using the PowerFloor for those reasons (acoustic and rigidity), not for thermal mass (for that, we're increasing the slab thickness instead). There's definitely some thermal mass with the Hebel - much more than wood - but not a lot in the scheme of an entire house. Note that insulating mass can be a double-edged sword; insulation doesn't stop heat transfer (only slows it down); it makes the mass slower to heat up, but if/once it does then it's also harder to cool back down (or vice-versa). Mind you, if you plan it right you can use that to advantage, too. EDIT: Actually, there is one spot where we are using it for thermal mass - we have an upstairs living area that we're tiling to capture passive solar heating from northern sunlight (with the PowerFloor you can 'get away' with tiled flooring upstairs). But that's mostly for the benefit of that room only, and we don't consider that a significant amount of thermal mass for the house as a whole. 1000000% definitely add insulation. I have in my home and it makes a big difference minimising sound transfer. Insulation is pretty cheap and definitely worth it 2 6191 Engineering timber is certainly a less fuss option, times cheaper to supply and install and better withstands humidity. 1 15907 Hi there, I'm a conplete newbie to this, but I'm looking to put a floor down in my 6x9m shed.
