    Playing with Builddesk and cannot find how to add fixings to a new material / layer. If I drag in the existing celotex products, they bring fixings with them. However if I try and create a new material, I cannot add fixings to it. Any ideas from out there?

    Great program but a bit limited in the available materials.

    Ok, here you go.

    Create new material
    Add all properties etc as normal
    Select material properties tab at the top
    Select insulation for walls in the top set of options
    Select insulation that can be mechanically fixed in the bottom set of options
    Select 'Done' as normal

    There you have it. A newly created insulation material that contains metal fixings/wall ties.

    Hope that helps.

    Brilliant - thanks very much.

    Now, how do I change the standard fixings?

    To add further, if a material contains fixings, you can change the material of the fixing by selecting the "wall tie and fixing" materials on the right hand side. Click on the fixing line in the material in the calculation and drag and drop the new fixing material in the box in the fixing poperties box on the top left of the popup window. (That really doesn't make sense, but have a go and see if you work out what the hell I am saying)

    If you wish to add a new fastener material into the program, add a new material, then select the material properties tab and in the top options box tell build desk it is a fastener. Then go back to the first tab and insert the properies of the fixing.

    Ah, Ok brilliant thanks. Really impressed with this program, but disappointed that the range of materials seems fairly out of date.

    I really like Build desk U. I have used JPA Designer (or whatever it is called) before and this is head and shoulder about it in terms of useability and functions. I agree that there is a limited materials library as standard, BUT they could put every material under the sun in there, and you would still find that there is loads of stuff you wany to add.

    My own library is now huge and has been developed over the last 4 years!

    Can you export it? :bigsmile: Makes me wonder if they should not set up a community and or create a mechanism for being able to download the materials you need. Wouldn't be that hard to do.

    My only complaint is that you need to remember to create a copy before you play with a build-up as there is no 'save as' function.

    Materials info is clearly ideal for crowd-sourcing online. If everyone filled in the materials they used (or produced) we'd all have a pretty-good approximation of 'everything' soon enough. Builddesk are missing a trick there.

    I agree Borpin, surely it cannot be too hard to create a 'save as' function so you can play around with various options as I tend to do before deciding what best fits the purpose.

    The annual license is a bit of a pain too as it doesn't actually seem to get updated as an annual upgrade? or maybe I am missing something...

    Too right! Unless we all set up an online sharing community for Builddesk, the hard work of people like Timber remains a valuable commodity really. In fact some of the smaller greener suppliers could pay for this service to add their products as it makes them a little bit easier to specify.

    edit...I really haven't worked out this quote function well...

    edit 2....try again on the quoting

    No worries regarding the (sort of) tutorial.

    On a more serious note, regarding my library, there is a lot of 'experimental' stuff in there. I.e. lots of materials with similar but differing properties so that I can see how altering the moisture vapour resistivity of layers changers condensation risk. For that reason I would not want to just throw it out there for people to start using unless they understood it.

    Also, I find adding material properties is not that hard, and nearly all the information you need is out there online.

    Hi Timber, Any chance you could explain an airspace in BuilddeskU as there are (seemingly) millions of them! I am playing with using Icynene between rafters, OSB, PIR as a roof build-up (looks very promising). The problem is, I need to keep the thickness of the Icynene to less than the rafter depth to avoid condensation. This is OK as it will then be the service void, but how do I show that on Builddesk. Another complication is that these are attic trusses, so only a portion of it is strictly a service void; the rest will be a warm loft.

    Also do you know if you need to eliminate all condensation risk, or is a small amount acceptable (in that it dries out next month)?

    In simple terms...

    If you rafters are 150 mm deep and you are installing 100 mm of Icynene between the rafters with a 50 mm air void below you:

    *Drag Icynene into the roof buildup and set depth to 100 mm
    *Add inhomogeneous layer to the insulation and set timber fraction to (normally 12.5 to 15%)
    *Drag a 50 mm un-ventilated air layer with horizontal heat flow
    *Add inhomogeneous layer to the air layer (it will remember the timber fraction you set (this can’t now be changed to a different fraction)

    You should now have 150 mm deep rafters with 100 mm insulation and a 50 mm unventilated air layer.

    As for condensation risk, I personally consider any risk to be a failure if timber and wood based board materials are involved. Continual and cyclic wetting will degrade wood based boards over time. Also the calculations work on a ‘perfect’ principal. I.e. if you are relying on a polythene VCL to stop condensation and you get a risk of condensation, if there are any holes or weaknesses in the VCL the risk will be worse. If you are not relying on a VCL this might be a bit different, and open to pragmatic interpretation.

    Hi Timber, Thanks. No VCL just breathing! :bigsmile:

    Is Build desk still free do you know? I installed it on a work PC years ago and left my library there, would really like to have it at home now I have a pc as well as my tusty Apple..

    If memory serves, you can get a 30 day free trial, but it is £150 a year after that.

    Or reload it into a Virtual Machine each time it expires...... Don't know why they expire it. The output is no use for official calculations as it has a big watermark across it.
