Roof systems and panel clip arrangements therefor

Abstract

A thermal clip arrangement for a roof panel system, such as a standing seam roof system, wherein the thermal clip arrangement includes a non-metallic anchor block which holds a slideable metal clip.

1 . A roof clip arrangement comprising: 
 a tab portion for attachment to roof cladding; and    an anchor portion;    said tab portion being slidably mounted with respect to said anchor portion;    said anchor portion having a coefficient of thermal conductivity less than that of metals.    
   
   
       2 . The roof clip arrangement according to  claim 1 , wherein said anchor portion comprises a non-metallic material.  
   
   
       3 . The roof clip arrangement according to  claim 2 , wherein said anchor portion comprises a plastic or polymeric material.  
   
   
       4 . The roof clip arrangement according to  claim 3 , wherein said anchor portion comprises a main body consisting essentially of a plastic or polymeric material.  
   
   
       5 . The roof clip arrangement according to  claim 3 , wherein said plastic or polymeric material comprises at least one of: plastic foam; PVC; CPVC; FRP; LEXAN; at least one composite comprising at least one plastic or polymeric material; at least one reground or recycled materials that is at least partly polymeric or plastic.  
   
   
       6 . The roof clip arrangement according to  claim 1 , wherein said anchor portion has a coefficient of thermal conductivity less of less than 1.0.  
   
   
       7 . The roof clip arrangement according to  claim 1 , wherein said anchor portion is formed from at least one material substantially immune to UV-degradation.  
   
   
       8 . The roof clip arrangement according to  claim 1 , wherein said tab portion comprises a clip arrangement adapted for attachment to roof cladding.  
   
   
       9 . The roof clip arrangement according to  claim 1 , wherein said anchor portion comprises at least one centering guide for guiding at least one fastening element to facilitate fastening of said anchor portion to a portion of a roofing arrangement.  
   
   
       10 . The roof clip arrangement according to  claim 9 , wherein said tab portions comprise at least one notch which aligns with said at least one centering guide to facilitate centering of said tab portion with respect to said anchor portion.  
   
   
       11 . The roof clip arrangement according to  claim 1 , wherein said anchor portion comprises a slot for accommodating said tab portion, said slot being adapted to substantially prevent movement of said tab portion in a direction different from a sliding direction.  
   
   
       12 . The roof clip arrangement according to  claim 11 , wherein said slot comprises a T-shaped slot.  
   
   
       13 . The roof clip arrangement according to  claim 1 , wherein said tab portion is formed from metal.  
   
   
       14 . The roof clip arrangement according to  claim 13 , wherein said tab portion is formed from light gauge stainless steel.  
   
   
       15 . The roof clip arrangement according to  claim 14 , wherein said tab portion is formed from galvanized steel with a zinc or zinc alloy coating.  
   
   
       16 . The roof clip arrangement according to  claim 1 , wherein said anchor portion has an asymmetrical cross-section in a plane perpendicular to a direction of sliding of said tab portion.  
   
   
       17 . The roof clip arrangement according to  claim 16 , wherein said anchor portion comprises an asymmetrical foot portion for accommodating at least one fastening element.
