Roofing and façade systems are among the most critical components of a building, serving as the primary barrier between the structure and the external environment. Rain, snow, wind, solar radiation, and temperature fluctuations are first encountered at these surfaces. For this reason, sealing solutions used in roof and façade applications not only prevent water ingress but also contribute significantly to the durability of the building envelope, energy efficiency, and long-term service life.
Over time, joints, connection details, and penetration points may become vulnerable due to structural movement, material aging, or environmental exposure. Water infiltration at these locations can reduce the effectiveness of thermal insulation, promote corrosion of structural components, and lead to moisture-related damage within the building interior.
Roof and façade sealing applications are widely used in the following areas:
Metal roof joints
Sandwich panel connections
Roof flashing around chimneys
Roof windows
Gutters and downpipes
Façade panel joints
Glass roof systems
Roof penetrations (ventilation ducts, service penetrations, etc.)
Balcony and parapet details
Solar panel mounting points.
Products used in these applications are expected to provide long-term resistance to UV radiation, precipitation, temperature fluctuations, and prolonged exposure to outdoor environmental conditions.
Technologies Used
Polyurethane Sealants
Polyurethane sealants are widely used in roof and façade details requiring high mechanical strength.
Their elastic properties allow them to accommodate structural movement while providing durable, long-lasting sealing performance.
Typical applications include reinforced concrete joints, roof joints, precast concrete elements, and metal connections.
Hybrid Polymer Technology
Hybrid Polymer-based products provide excellent adhesion combined with permanent elasticity for exterior roof and façade applications.
Their principal advantages include application on damp substrates, outstanding UV resistance, paintability, low shrinkage, and excellent adhesion to a wide variety of construction materials.
Their compatibility with metal, concrete, wood, aluminum, PVC, and composite substrates also makes them a preferred solution for maintenance and repair applications.
