Leadax lead replacements are suitable for Code 5 lead sheet applications and a wide range of watertight connections. Explore the applications and find the right Leadax solution for your project.
Lead replacements were once used mainly for traditional lead sheet applications. Leadax can be used much more widely to create high-quality waterproofing details.
That includes applications supporting the energy transition, changing requirements for indoor climate control, and efforts to reduce the cost of construction defects. Need help choosing the right solution? Our team can help you assess your project.
