INSTALLATION

INSTALL IN 3 EASY STEPS!

Already cut to size and ready to install, JointFlash slides conveniently behind the siding and is held securely in place as you nail the end of the piece.

No other flashing system is installed quicker or easier!

Step 1:

Install the first pieces of lap siding without nailing the end near the butt joint.

Step 2:

Simply tuck the piece of JointFlash™ behind the loose end of the previously installed siding. Make sure the JointFlash™ is centered on the joint and is overlapping by at least one inch.

Step 3:

Install the remaining piece of siding and nail down the butt joint as usual to hold the JointFlash™ securely in place.

JointFlash was designed by professional siding contractors to save you time and money, without sacrificing quality.

Whether you’re working on residential homes, multi-family units, or commercial projects, JointFlash provides the reliable protection and quality finish you need.

With JointFlash products, you’re not just installing siding—you’re reinforcing the integrity of every build. Our solutions offer long-term defense against the elements, ensuring siding looks and performs at its best for years to come.
