Browse Forums Building A New House 1 Jun 18, 2015 9:06 pm Hi! I've been sent a proposal for an alternate solution for the first floor external wall cladding. My builder is wanting to use a polystyrene/foam cladding for the first floor - it's a brand called 'EzyClad'. We knew this going to be the case, but we didn't know it was going to be a non-complying product. What also worries me is that we're to sign that we acknowledge that it's not complying - which worries me come time to insure the home and god knows what other future problems we could have. According to the brief research I've done, 'EzyClad' doesn't exist anymore. In the proposal, I'm written the following advice: "The alternative solution proposes the use of an external wall cladding that does not the requirements set out in Part 3.5.3 of the National Construction Code deemed-to-satisfy provisions. The wall system however does meet the relevant performance requirements associated with this part of the National Construction Code Volume 2..... We understand the polystyrene walls do not meet the deemed to satisfy requirements of the National Construction Code Vol 2 in that polystrene walls may only be used for construction if they satisfy the National Construction Code performance requirements P2.1, P2.2.2 & P2.6.1" Lastly, what information is left online about EzyClad; states that it in-fact does comply with all codes. I'm quite happy for everyone to discuss and provide their input. I'd hate to think I'm getting a substandard product. Re: Alternate Solution - polystyrene cladding 2Jun 18, 2015 10:12 pm Basically what the national codes say is there are a number of 'traditional' methods of cladding which are said to be complying and EzyClad isn't one of those. The National Building Codes however do recognise that new methods are being developed and are acceptable if they meat certain performance requirements (such as being weatherproof, insulating etc) If you want to read the codes you can download them at http://www.abcb.gov.au/ncc-products.aspx The Harder You Try - the Luckier You Get !

Re: Alternate Solution - polystyrene cladding 3Jun 19, 2015 9:18 am There are a lot of factors that come into consideration with any New building material,my advice as an engineer that does structural repairs is for you to think very carefully about the consequences when surface finishes start deteriorating ie, durability, strength, cost of repairs, insurance costs, weigh up the pros and cons. etc,etc The code does recognised new materials/building systems they are required to be certified by structural engineers..I suggest you also get the full test results which should include time dependant computer simulations.eg these factor in stress, thermal, chemical, environmental,displacement,etc, changes in the material/building system over a period of time.
