The primary seal is the key to preventing moisture vapour transmission and gas permeation. the butyl used for this purpose seals the spacer width and prevents moisture from entering the insulating glass unit on the one hand and the gas contained in it from escaping on the other hand.
The secondary seal connects the panes of insulating glass units with each other and hermetically seals the spacer width. The space between the spacer bar and the edge of the pane is filled with sealant and thus serves as a second level of sealing.All of our secondary sealants are, of course, fully compliant with EN 1279.
Unlike most other materials, glass is a material that represents lightness, timeless elegance and transparency. This is why glass façades have had a significant impact on modern architecture and have defined our cityscapes for decades. On the one hand, they must satisfy the most demanding aesthetic expectations; on the other hand, as smart technical systems, the must fulfil a multitude of construction-relevant functions. These requirements are reconciled perfectly by all-glass façades built with structural glazing.
Our high-performance, silicone-based structural glazing products guarantee that such façades with their fascinating designs will be long-lasting even under extreme climate conditions and will preserve their quality for years to come. Furthermore, with Ködispace 4SG, our Warm Edge System developed especially for use in façades, extremely tight and durable gas-filled façade glass panes can be realised.
