Installing The Insulated Siding Panels
Lock the insulated panel into the EasyStart strip and slide the vinyl panel into the 
pocket of the corner post. The factory panel has a 3/4" foam setback so that only the 
vinyl will go into the pocket when using a factory cut end. Finish the field cut end of 
the first course by cutting the panel to proper length, and sliding it into the outside 
corner post receiving channel allowing 1/4" for movement (Note: allow 3/8" in all 
receiving channels if the temperature is under 40 degrees F). It may be necessary to 
remove some of the insulation from the back of the panel to allow the panel to be set 
into the corner posts, or j-channels.
How To Seam And Overlap
The foam is set back 3/4" from both ends of the Insulated Siding panel. The adhesive 
begins 2" back from each end of the foam. The correct way to seam two (2) Insulated 
Siding panels is to slip the vinyl edge of the bottom portion of the seam between the 
foam and the vinyl on the adjoining panel- then slide the panels together until the 
proper foam-to-foam contact is achieved.
Installation Under Window and Crown Area
Several options are available too secure the topmost 
Insulated Siding panel below the eaves. Each method 
will require cutting the panel to the desired width, then 
using a hot knife, or utility knife to clean enough foam 
from the back of the cut Insulated Siding panel so that 
the snap lock punch can be used to properly crimp the 
Insulated Siding panel as illustrated below right.
Using an undersill molding (A): 
Build out an undersill/utility 
molding with a furring strip to the 
proper dimension. Snap lock the 
properly fit Insulated Siding panel, 
and slide into undersill molding checking 
for proper free movement.
Using a j-channel (B): Snap lock the properly fit 
Insulated Siding panel, and slide into the j-channel 
checking for proper free movement.
A Dual Undersill Molding, or Snap-in Crown Molding may also be used to 
secure the top course of siding. When using a Snap-in Crown Molding, the top 
of the panel will be nail slot punched, instead of snap-lock punched.
Note:
Foam-to-foam 
contact is critical 
for proper long 
term weathering 
and optimal  
insulation value.
