Standard EN 13022-1 določa zahteve za ustreznost za uporabo podprtih in nepodprtih steklenih proizvodov za uporabo v okviru strukturne zasteklitve (SSG). Slika 1 prikazuje štiri shematske risbe sistemov strukturne zasteklitve, slika 2 pa tri sekcijske risbe sistema strukturne zasteklitve tipa II za namene ponazoritve. Ta evropski standard za steklene proizvode se šteje za dopolnilo k zahtevam, opredeljenim v ustreznih standardih, v zvezi s preverjanjem ustreznosti za uporabo v sistemih strukturne zasteklitve. V tem evropskem standardu so obravnavana le natrij-kalcijeva silikatna stekla. Plastična zasteklitev je zunaj področja uporabe tega evropskega standarda. Vsi stekleni proizvodi, ki izpolnjujejo zahteve tega evropskega standarda, so ustrezni za uporabo v sistemih strukturne zasteklitve, kot je opredeljeno v smernicah ETAG 002 »Sistemi strukturne zasteklitve«. Vsi stekleni proizvodi so vgrajeni in vezani v podporo pod nadzorovanimi okoljskimi pogoji, kot je opisano v točki 5 standarda FprEN 13022-2:2013. Ko ima zunanje tesnjenje izolacijskega stekla strukturno funkcijo in/ali je izpostavljeno UV-sevanju brez zaščite, se v zasnovi stekla dovoli le tesnilna masa na osnovi silikona.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2014 and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13022-1:2006+A1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 13022-1 is one of a series of interrelated standards dealing with: — glass products for structural sealant glazing systems; — installation of glass products in a structural manner on building façades; — UV-resistant and structural sealant for use in structural sealant glazing. The interrelated parts are: — EN 13022-1: Glass in building — Structural sealant glazing — Part 1: Glass products for structural sealant glazing systems for supported and unsupported monolithic and multiple glazing — EN 13022-2: Glass in building — Structural sealant glazing — Part 2: Assembly rules — EN 15434: Glass in building — Product standard for structural and/or ultra-violet resistant sealant (for use with structural sealant glazing and/or insulating glass units with exposed seals) According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13022-1:2014 (E) 7 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

This part of the standard is one of a series of interrelated standards dealing with:  glass products for structural sealant glazing systems;  installation of glass products in a structural manner on building façades;  UV-resistant and structural sealant for use in structural sealant glazing. The interrelated parts are:  EN 13022-1: Glass in building — Structural sealant glazing — Part 1: Glass products for structural sealant glazing systems for supported and unsupported monolithic and multiple glazing  EN 13022-2: Glass in building — Structural sealant glazing — Part 2: Assembly rules  EN 15434: Glass in building — Product standard for structural and/or ultra-violet resistant sealant (for use with structural sealant glazing and/or insulating glass units with exposed seals) kSIST FprEN 13022-1:2013

FprEN 13022-1:2013 (E) 4 1 Scope 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 FprEN 13022-2:2013. 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.

FprEN 13022-1:2013 (E) 7 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 minimised. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
