[RE-wrenches] attaching to roof decking - Foam Insulation Install

Mon Jul 19 21:34:32 PDT 2010

after a few requests, i have not been getting any feedback from Direct Power regarding pull out specs for their 'easy feet', which i need for my engineer to be able to give me the go-ahead to use them.does anyone care to comment on the fact that this mounting method only attaches to the roof decking and not the rafters?  
i have always been under the impression that if you only attach your racking to the roof decking, it (the decking) could 'rip right off the roof' in that worst case scenario wind storm! but by anchoring to the trusses, the whole roof structure would/should withstand the wind load.  or maybe i was just under the wrong impression and the spiel was that the decking would not hold the screws and the screws would pull out!so am i to understand that by using several (of the right size) screws at each anchor point, the decking (if adequate) will be able to support an array (even if tilted up to 60 deg)???
cheers,benn

I have also had a great experience using "Easy 
Feet" from Direct Power.  You use four of their screws per foot and Jeff 
Randall there can give you pull out specs in roof decking, as I recall they 
match or exceed that of the Lag/rafter combo.

  Antony,
  Right on!  The Eco-fasten will solve the issue - it's been pull-out 
  tested sans-rafter penetration. Have bought the eco-green fasteners from them, 
  will again.  As far as dealing with them - it's a great pleasure to be 
  able to talk to someone with good product knowledge 
  that will take the time to answer stupid questions.

Have you looked at EcoFasten mounting.  They have a 
    mount that uses 8 screws per attachment, so can theoretically hold without 
    going into the rafters.  Then could use a large flashing over that to 
    integrate with the shingles. 

    I think they're an offshoot of AlpenSnowguards in Vermont.  We 
    started working with Alpen to source S5 clamps several years ago, and have 
    found them great to work with.   

    We're a West coast company - there were lots of other distributors 
    closer, but Alpen got and kept our business.  It's kind of funny - when 
    I call them, I feel like I'm talking with someone in one of those old 
    hardware stores with everything you need right there in bins, and when I 
    call the other guys it seems like someone in a sales office who never 
    handles the product.  

    The EcoFasten crew is similarly helpful, and they have some well 
    thought out products.  The name I have in my rollodex is Chris Sterns, 
    at 877-859-3947.

    Their 
    website is pretty comprehensive, and includes leak and load tests and 
    building code info.  Other cool mounting products too.
