High-Tech Solutions for Perfect Facades Architecture thrives on change. On creative ideas and bold solutions that fascinate and surprise us every time. Curtain walls are a particularly severe challenge for planners, because they not only set the character of the structure but must also meet stringent requirements. Creative Facade Architecture To strike the ideal balance between aesthetic appeal and energy efficiency, architects are increasingly turning to glass for curtain wall construction. As transparent structural glazing walls, single or double glazed or even double skin facades. Glass can...

For structural glazing silicone adhesive sealants Sikasil® SG see page 16. Four-Sided Structural Glazing Two-Sided Structural Glazing Optimum Transparency Optimum Safety Structural glazing systems can be either two-sided or four-sided, with each design having its own particular advantages. In general, for efficient and energy-saving building management, double and triple glazing is recommended. Frameless Appearance Four-sided structural glazing is impressive first and foremost because of its monolithic frameless appearance. All four sides of the large-format pane element are bonded to an adapter...

These fasteners are embedded in holes in the glass pane with “glass cement”. The glasses can be single...

16 Stock Exchange; Johannesburg, South Africa 17 Zorlu Plaza, Istanbul, Turkey Structural Glazing – Sophisticated Architecture and Innovative Technology Structural glazing modules are subject to extremely high stresses. They must accommodate wind and snow loads as well as thermal expansion, and permanently transfer the forces to the support structure, while also withstanding weathering over many years. Specialized Products Durable Construction High-modulus Sikasil® SG silicone adhesive sealants offer the best properties for this purpose. The latest development with highest design factor is described...

18 Airport Barajas Madrid, Spain; Richard Rogers & Estudio Lamela Joint Design – Correct Planning is Essential In structural glazing, the adhesive joints should be planned and arranged according to optical requirements, but they should also take into account dimensional changes in the adjacent parts under the effect of temperature and the movement capability of the silicone adhesive. The joint design thus combines shape with functionality. Important Seven criteria must be observed: 1. The joint seal must be able to freely accommodate tensile and compressive movements between the joint edges....

A Right joint dimension in its original state (h = joint bite, e = joint thickness) B Besides tensile movements the adhesive bond C also absorbs shear movements in all directions. D It is essential that bonding on three sides is avoided. Glass pane Structural glazing joint Calculating the Joint Thickness e With all structural glazing constructions, the adhesive bond is subject to considerable shear movements. The joint thickness (glue line thickness) must therefore be designed so that the movement capability is not exceeded. Criteria for Calculating the Joint Thickness e - Dimensions of the elements...

Calculation Values for Sikasil® SG and Sikasil® IG products ETAG Movement capability (ASTM C719) 3b. Calculation of the minimum Joint Thickness e (ETAG 002) The calculated deformations of the long and short panel edges yield the total movements according to the formula above (Pythagoras’ theorem). ∆l = total change in length v = vertical h = horizontal 3a. Calculation of the minimum Joint Thickness e (ASTM C1401) Sikasil® SG silicone adhesive sealants are permitted maximum elongation of ±12.5% (c = 0.125). The total of expansion and contraction must not exceed 25%. With these restrictions, the...
