One of the last steps in installing glass curtain walling is creating a weathertight barrier against air and water infiltration between glass panels. Sealing the joints with a silicone sealant is a critical process that ensures the glass curtain wall\u2019s structural integrity, weather resistance, and long-term durability. A properly sealed curtain wall also helps to improve the building’s energy efficiency by reducing air leakage and heat transfer.<\/p>\n\n\n\n

For professional builders, sealing glass curtain walls is a critical final task that demands precision, expertise, and the right choice of materials. The builders must adhere to local and project-specific standards when choosing a sealant for curtain walls (e.g., ASTM, EN). In Penosil product range we have a few sealants for sealing glass curtain walls, such as Penosil Facade & Glazing Silicone 340\/340c<\/a>.<\/strong> It is a neutral alkoxy-cure silicone developed specifically for facade weatherproofing and glazing applications.<\/p>\n\n\n\n

Why use neutral silicone for sealing glass curtain walls instead of other types of sealants? Well, compared to other types of sealants, the neutral cure sealants such as alkoxy and oxime silicones offer a non-corrosive cure. This means that neutral silicones can be used in contact with aluminium and other most common curtain walling materials, without damaging them or degrading the sealant joint. Metals, laminated glass and some glazed surfaces are not always compatible with other types of sealants. Also, neutral silicones are totally UV proof and have extremely long service life which makes them perfect for facade works. Even though neutral silicones can be used in contact with many materials, we always recommend performing a compatibility test with adjacent materials, such as the glass, aluminium frames, and other components before starting the work.<\/p>\n\n\n\n

Neutral alkoxy silicone forms a strong bond between glass and frame, and ensures a durable seal that is weather-, UV and ageing resistant. The non-sagging and permanently elastic formula of Penosil Facade & Glazing Silicone 340\/340c<\/a><\/strong><\/strong> has been specifically developed for sealing vertical and horizontal facade joints. Its high movement capability (\u00b125%) accommodates the movements of the curtain wall components due to temperature changes and other factors, preventing cracks and maintaining the integrity of the seal. This versatile product comes in ten different colour options and can also be used for other types of facade works such as weatherproofing joints between concrete facade panels, sealing window and door perimeter joints, and glazing works.<\/p>\n\n\n\n
