Wooden constructions are on the rise again – encouraged by a strong trend towards sustainable and resource efficient buildings. Load-bearing timber-glass composite elements – a novel concept to use the in-plane loadbearing potential of glass – could contribute to a more efficient use of materials in façades. The current study relates to the adhesive bond between the glass pane and the timber substructure. The applicability of structural sealants such as silicones is limited due to their distinct flexibility which leads to large deformations of the joint. Further potential arises from the use of adhesives of medium and high stiffness. Their general performance as well as their durability have not
yet been evaluated with respect to the proposed use in building constructions. This paper draws attention to the ageing stability of two promising adhesives. Small-scale adhesively bonded specimens which are composed of a wooden and a glass piece are exposed to different ageing scenarios which relate to the impacts typically encountered in façades. Based on the results it can be concluded that the considered high-modules adhesives enable an increase of characteristic failure loads and a reduction of joint deformation, but also reveal shortcomings regarding their ageing stability.
