Lineal Starter Application for Windows
and Door Surrounds
When securing window and corner starter strips, outside corner
pieces (OSCP), inside corner pieces (ISCP), one piece corners,
lineals—basically, any vertically mounted siding product—always
place the top nail (or staple) first, and in a manner that allows the
part to hang from it without dropping. This promotes movement
downward only, a must for a good corner joint. This is the only time
you should not center a nail (or staple). It is also preferred to use
the nail slots closest to the locking area (when using product with
double nail slots).
Remember to place the nails for the horizontal pieces in the center
of the nailing slots as shown. Space nails 8" to 10" apart.
Using a 1/2" J-channel as a starter for lineals
NOTE: Slide the lineals on from either end of the
J-channel (the lineal will not snap over the J-channel
as with a New Construction Starter Strip), or pull the
J-channel away from the window slightly and zip the
lineal into place.
If the opening has no framework, such as a brick molding, use the
metal starter (illustrated below left), or the Remodeling Window and
Door Starter (illustrated below) in place of the New Construction
Window and Door Starter Strip shown above. The lineal’s locking
leg will fit behind the aluminum starter and into the receiving
pocket of the Remodeling Window and Door Starter.
