Continuous insulation (c.i.) systems finished with 3-coat plaster offer new challenges to architects and installers alike. Controlling costs while designing an effective installation method that minimizes moisture intrusion and costly RFI’s can be a daunting task. 

  Our Diamond-Furr Lath Attachment products have been developed to improve building performance while providing exceptional cost, labor and time saving elements. 

   Diamond-Furr lath attachment products eliminate 100% of the penetrations throught the moisture barrier at termination points and over 55% of the field penetrations. The Diamond-Furr line accomplishes four steps in one product – Trim, Flashing, Furring and Lath Attachment. 

 DIAMOND-FURR Features / Benefits:

Polyiso insulation meets NFPA 285 without glass mat gypsum sheathing Eliminates need for gypsum sheathing
Polyiso insulation offers R 6.5 per inch additional insulation value
POLYISO insulation

Not hazardous fiberglass dust like glass mat sheathing

or poluting polystyrene particles

4×12 sheet of polyiso insulation weighs 88% less than 4×8 sheathing  Less worker fatigue and easier scaffold staging
4×12 sheet covers 33% more area than 4×8 sheathing Faster installation time
Polyiso insulation is easier to cut than glass mat sheathing Lowers potential for worker injury
Foil-faced polyiso insulation serves as air / moisture barrier Eliminates the need for a 2nd layer of building paper
Diamond-Furr eliminates 100% of penetrations at termination points Reduced moisture intrusion liability 
Diamond-Furr incorporates tie wire connections Reduced cracking and no caulking screw heads
No screws through water barrier at termination points  Reduced need for peel & stick barriers
Diamond-Furr provides continuous 3/8″ furring Best lath embedment possible


  The Diamond-Furr window drip (pt# DFWD-x375) is designed to be installed before the continuous rigid insulation is in place.  The built-in  furring strip on the drip edge extends just beyond the foam creating a perfect furring platform for metal lath. The result is superior lath embedment as the uninterrupted 3/8″ furring never allows the lath to come in contact with the moisture barrier. When installed correctly the Diamond-Furr drip edge eliminates 100% of the fastener penetrations through the weather barrier. Yes 100%!

We recommend using the Diamond-Furr drip edge along with the full line of Diamond-Furr trims for a complete system and the best possible protection against moisture intrusion, cracking and thermal bridging.
