Re: Hebel PowerBlock ? 15Apr 14, 2023 11:41 pm I think you would need ERV (not just HRV) system in order to control humidity through mechanical ventilation if you are trying to hit PassivHaus level of air tightness. I am not of big supporter of PassivHaus idea for Australia (for Norway and Russia yes, but not for Sydney) where people are usually spending a lot of times outdoors and rely a lot on natural ventilation. R value of 30 cm Hebel block should be around 2.0 but when multiplied with high density multiplier and thermal mass properties, it should be probably around 3.0 for Sydney. If you are targeting PassiveHouse standards then you might be probably adding another R2.5-3.0 of insulation on top? But if you are looking for a breathable one, then you should avoid EPS and focus in Rockwool or mineral wool. That means you might require vented facade and external cladding, this is not going to be cheap. Re: Hebel PowerBlock ? 16Apr 15, 2023 7:58 pm Have witnessed the high and lows of people using Hebel blocks over the years. Well built places in good time frames to a couple of unfinished places that have been demolished. Mostly found block and bricklayers are not interested in laying Hebel. Although the blocks are accurate in dimension keeping them level is achieved by sanding, not building bed glue. Brickies wont sand. Engineering is a massive stumbling block, have masonry footing design, could have tie down rods placed every 1m from footing/slab to roof. Speak with a distributor in your area to find any contacts for laying, check any work and make sure have a bandsaw. Hard plaster internally or gyprock internally is fine and you will find specs on that. Think about ceiling to wall junction, cornice, square set, who comes first or last etc. If double story best to get steel erected and build walls/set out to that, floor and start again. My understanding a solid wall has to be painted to prevent moisture ingress, caulking around doors/windows etc (same with solid 230mm brick walls) CSR where bringing in blocks from China plant, not sure what’s happening with that now, but last place involved with the customer was gifted blocks made in Australia Not sure what the difference is in Europe, seems to be “understood” better there 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 7019 ![]() Since you are in the design stage then I would direct your questions, in writing of course, to your designer. Depending on the trust you have in the competence of your… 4 6176 Would also like an opinion from anyone that has used xcem over hebel for floors. Thanks 1 15615 |
