SIPs are recessed out to fit on 2x4 or 2x6 plates.		  
     
Two top plates cross to form the wall corner.

 

  

     
Wider view of typical corner.		  

 
     
SIP construction ensure walls are straight.  
     
A spline is a long, thin "mini"-SIP used to connect SIP panels vertically. They ensure a strong, insulated connection between panels.		  

 

 

Patio door with conventional header.		  
     
Conventional header rests on jack stud, transferring load. The jack stud is secured by a recess in the SIP.

No king stud is needed.

 

 

  
     
Window that are approximately 2 feet wide or less can be cut right out of the panel.

Cut out pieces can be re-used elsewhere.

  
     
Cut out piece of SIP used as sill panel, reducing wastage.		  
     
Another example of cut-out SIP pieces being used to strategically to reduce wastage.

This approach is suitable for non-structural components. The SIP pieces maintain their insulative capacity by using foam adhesive on both sides and caulking the joints.

  
     
Window arches are easy with SIPs. Simply contour cut the shape right out of the SIP. 		 
     
Windows are easily foamed in.

 

  
     
Fastening a window.

 

  
     
A window fastened with nailing fins.

 

  
     
Bay windows are easy-to-build, straight, and leak-proof.		  

 

     
This picture shows the 2x8 pwf plating (PL) fastened to the poured concrete footing (CF). 		 
     
Panels (PN) sit on 2x8 pwf plating (PL) and concrete footing (CF). 		 

     
Thermapan foundation panels are composed of 7/16" oriented strand board interior plywood (OSB), expanded polystyrene insulation (EPS) and 5/8" preserved wood foundation exterior plywood (PWF). Sealing foam (SF) is applied along joints for insulation, air and vapour seals.		  
     
2x8 preserved wood foundation splines (SP) are used to join the panels together. The spline (SP) is fastened to the 2x8 preserved wood foundation plate (PL).		  

 
Next foundation panel (PN) is placed on plating and the fastening process is continued. Click here to watch WMV video of this step.		  

 
This 60 foot foundation section was completed in 2 hours.		  

 
Column (CL) can simply be cut into panels for point loads.		  

 
Two top plates (TP) are fastened to the top of the panels to secure them.		  

 
This 120 foot foundation section including top plates was completed in 6.5 hours. One carpenter and two helpers were required to install this project.

 

  

 

     
Electrical is done by sawing or routering a vertical chase and box. After wiring is positioned, spray foam seals the groove.

The SIP maintains its strucutural integrity and ability to support axial loads.

 

  
     
A vertical electrical chase from the ceiling, for light switches.		  
     
Electrical can be accessed through the floor joists.		  
     
In addition to floor joists, wiring for exterior walls can be accessed from interior partitions.
