This European Standard specifies requirements for the suitability for use of supported and unsupported glass products for use in “Structural Sealant Glazing” (SSG) applications. Four schematic drawings of SSG systems are shown in Figure 1 and three section drawings of an SSG type II system are shown in Figure 2 for illustration purposes. This European Standard on glass products is considered as a supplement to the requirements specified in the corresponding standards with regard to verifying the suitability for use in SSG systems.
Only soda lime silicate glasses are taken into consideration in this European Standard.
Plastic glazing is excluded from the scope of this European Standard.
Any glass products meeting the requirements of this European Standard are suitable for use in SSG systems as defined in ETAG 0021) “Structural sealant glazing system”.
All glass products are installed and bonded into the support under controlled environmental conditions as described in Clause 5 of EN 13022-2:2014.
When the outer seal of the insulating glass unit has a structural function and/or is exposed to UV radiation without any protection, only silicone based sealant are permitted in the construction of the unit.
NOTE 1 Retaining devices may be required by national regulations.
NOTE 2 In case of laminated glass and laminated safety glass, SSGS of types III and IV may be forbidden by national regulation.
NOTE The section drawings above are examples of structural sealant glazing system type II and IV.
SITUATION 1
The SSG seal is applied on face 2 of the insulating glass unit. The outer IGU sealant has no structural function and therefore only contributes to the resistance of the unit against the ingress of water (vapour and liquid) and air. Depending on the type and construction of the IGU sealant any leakage of gas from the unit will be minimized. The SSG seal need to have adhesion to the glass and steel surfaces to withstand the mechanical stresses that results from the exposure of the IGU to the climatic elements and in particular the effects of solar radiation.
SITUATION 2
The SSG seal is applied on face 4 of the insulating glass unit. The outer IGU sealant has a structural function as well as having to maintain the integrity and performance of the IGU.
SITUATION 3
The SSG seal is applied on face 2 of the laminated glass or laminated safety glass or monolithic glass unit. The sealant has a structural function and any loads applied to the glass will be transferred to it.
NOTE In case of laminated glass and laminated safety glass, SSG of types III and IV may be forbidden by national regulation.
