Fasten right, build strong

By Hunter Panels. 

From selecting the correct SIP fastener to dialing in drill speeds, understanding the specifics can make all the difference in your Xci Ply installation.  

When it comes to high-performance polyiso panels, Hunter Panels doesn't just deliver product, they deliver answers. Whether you're securing Xci Ply, Xci Ply Class A or Xci NB, the right fastening approach is critical to performance, speed and long-term durability. To help streamline your next install, we've compiled the most frequently asked questions about SIP fasteners and how to use them effectively across different base wall types. 

Question:  

Which style of SIP fastener is needed? 

Answer:  

Hunter Panels offers multiple styles of SIP fasteners for attachment of Xci Ply, Xci Ply Class A and Xci NB, depending on the base wall type. Plates are not required with these fasteners. 

Question: 

What length of fastener is needed? 

Answer: 

Minimum penetrations vary from a few threads up to 2.0″ depending on the fastener and base wall. Please reference DrJ TER 2102-05 or contact Hunter Technical for more info. 

Question: 

How many fasteners are needed? 

Answer: 

The fastening pattern is determined by several factors including stud spacing, Xci panel thickness and the weight of the cladding system. Use DrJ TER 2102-05 to determine the correct pattern. The technical team at Hunter Panels is available to assist with this. 

Question: 

Do the fasteners countersink? 

Answer: 

No, the fasteners are not meant to countersink. The head should rest on the surface of the panel. 

Question: 

What tools are used to install these fasteners? 

Answer: 

Typically, a screw gun is used to install these fasteners. Impact drivers are not recommended for concrete and CMU applications. SIP fasteners should not be struck with a hammer during installation. 

Drill speed recommendations: 

Speed up installation by going slower for steel, concrete and CMU applications. Higher drill speeds create excess heat from friction, which can cause fasteners to soften and lose their edge.  

For SIP/SD and SIP/SD-PT fasteners going into light gauge steel: 1500 – 2000 RPM  

For SIP/SD and SIP/SD-PT fastener going into concrete/ CMU: 900 – 1500 RPM  

For SIP/HD and SIP/HD-PT fasteners going into heavy gauge steel: 900 – 1500 RPM
