Finding the right adhesive or sealant to suit a specification is critical and Sika, a world leader in bonding, sealing and reinforcing solutions, both for on-site and for industrial applications, has fine-tuned their sealing and bonding solutions for the facades, fenestration and insulating glass market.
To strike the ideal balance between aesthetic appeal and energy efficiency, architects are increasingly turning to glass curtain wall construction. Glass can be well combined with other materials such as natural stone, metals or plastic coated metals, giving planners a wide scope for creativity. But facades must also provide long-term durability. This requires perfect adhesion between the components and highly elastic, weatherproofing solutions. These specifications call for high-tech products, which are tailored to meet specific demands and guarantee peak performance in every respect. Sika supplies a wide range of tried-and-tested, innovative facade products for every demand.
The facades are mainly responsible for the energy balance of a building. The excellent thermal insulating effect of bonded double- or triple-glazed units with coated glass – sealed by dual-seal technology – can save much of the energy otherwise consumed for heating or cooling.
Structural bonding of the glass to the sash frame stiffens the window. As a result, the glass supports the frame instead of the usual situation where the frame supports the glass. Reduced requirements to the structural strength for the sash frame enable numerous options for improved window structures. The face widths of the sash frames are narrower, which increases the incoming light and improves the insulation characteristics. Permanent secure bonding of the glass with the frame reduces maintenance costs because the structure retains its dimensional stability. Settling of the sash frames is largely excluded. Automation of the glazing process and reduction of steel reinforcement make enormous contributions to improved productivity in window manufacturing.
