Note: If the installation of the first story of Amvic ICF will take a few days to complete, it is recommended to protect the chalk line to avoid it being washed away by rain or wind gusts.

Note: It is possible to snap the chalk line at 1/2” (13mm) away from the face of the actual wall. This becomes beneficial when the wall placement needs to be adjusted by allowing the installer to see where the marked outline is located.

Note: It is advisable to follow window manufacturers guidelines for rough opening sizes to ensure proper dimensions are achieved with taking into consideration the buck configuration. It is important to verify with the window manufacturer that the specified rough opening is the size of the buck and not the size of the actual window.

Note: Most windows in ICF construction should be placed on the solid area of the opening and not directly on top of the of the EPS panels. This will provide proper support and eliminate potential issues of sagging and movement over time.
