Facade joints are sealing systems designed to protect the gaps between building elements from environmental exposure. These joints are engineered to safely accommodate the expansion and contraction caused by temperature fluctuations, wind loads, vibration, and the natural movement of the building structure.
In modern buildings, façade systems serve not only as architectural features but also as critical components of the building envelope. They play a vital role in resisting rainwater and wind, controlling air infiltration, improving energy efficiency, and enhancing acoustic performance. For this reason, selecting the appropriate sealant for façade joints is essential to ensuring the long-term performance of the building.
Facade joint sealing is widely used in the following applications:
Aluminum curtain wall systems
Precast concrete panels
Natural stone façade cladding
Composite panel façades
Glass façade systems
Window and frame perimeters
Reinforced concrete structural joints
Façade repair and renovation projects.
Joint width, joint depth, and the anticipated movement capability should be determined during the design phase, and the selected sealant must be capable of meeting these performance requirements.
Technologies Used
Neutral Silicones
Neutral-cure silicones are among the most widely used sealing systems for façade applications.
Their excellent compatibility with aluminum, glass, concrete, and a wide variety of façade materials makes them a preferred solution.
Thanks to their outstanding UV resistance, excellent weatherability, long service life, and high movement capability, they are particularly suitable for exterior façade applications.
Polyurethane Sealants
Polyurethane sealants have been used for many years in façade joints and movement joints requiring high mechanical strength.
They provide reliable performance in reinforced concrete joints and precast concrete panel connections.
Hybrid Polymer Technology
Hybrid Polymer-based products combine excellent adhesion with long-lasting elasticity.
Their paintability provides a significant advantage in renovation and refurbishment projects.
They are particularly well suited for façade details incorporating multiple construction materials, including concrete, natural stone, metal, painted surfaces, wood, and composite materials.
