Glass in building - Glazing and airborne sound insulation - Product descriptions, determination of properties and extension rules
This European Standard assigns sound insulation values to all transparent, translucent and opaque glass products, described in the European Standards for basic, special basic or processed glass products, when intended to be used in glazed assemblies in buildings, and which exhibit properties of acoustic protection, either as a prime intention or as a supplementary characteristic.
This document outlines the procedure, by which glass products may be rated, according to their acoustic performance which enables assessment of compliance with the acoustic requirements of buildings.
Rigorous technical analysis of measurement data remains an option, but this standard is intended to enable the derivation of simpler indices of performance, which can be adopted with confidence by non-specialists.
By adopting the principles of this standard the formulation of acoustic requirements in Building Codes and for product specification to satisfy particular needs for glazing is simplified.
It is recognised that the acoustic test procedures contained within EN ISO 140-1 and EN ISO 140-3 relate only to glass panes and their combinations. Although the same principles should be followed as closely as possible, it is inevitable that some compromises are necessary, because of the bulkier construction of other glazing types, e.g. glass blocks, paver units, channel-shaped glass, structural glazing and structural sealant glazing. Guidelines on how to adapt the test procedures for these glazing types are offered in Clause 4.
All the considerations of this standard relate to panes of glass/glazing alone. Incorporation of them into windows may cause changes in acoustic performance as a result of other influences, e.g. frame design, frame material, glazing material/method, mounting method, air tightness, etc. Measurements of the sound insulation of complete windows (glass and frame) may be undertaken to resolve such issues.

Dieses Dokument befasst sich mit der Festlegung und Beurteilung von Schalldämmwerten für alle durchsichtigen, durchscheinenden und opaken Glaserzeugnisse, die in den Europäischen Normen über Basisglaserzeugnisse, spezielle Basisglaserzeugnisse oder über weiterverarbeitete Glaserzeugnisse mit Schallschutzeigenschaften, vorgesehen für den Gebrauch in verglasten Bauteilen von Gebäuden, beschrieben sind und die entweder als Hauptzweck oder als ergänzende Charakteristik Schalldämmung aufweisen.
Dieses Dokument bezieht sich auf Labormessverfahren, die in EN ISO 10140 1:2016, Anhang D, beschrieben werden, und legt erweiterte Regeln fest, die ohne weitere Prüfungen angewandt werden können. Es liefert außerdem typische Schalldämmwerte für einen großen Bereich gängiger Glaserzeugnisse, die verwendet werden können, wenn keine Messwerte zur Verfügung stehen.
Alle Überlegungen dieses Dokuments beziehen sich nur auf Scheiben aus Glas/Glaserzeugnisse. Ihr Einbau in Fenster kann Änderungen der akustischen Eigenschaften verursachen, die auf andere Einflüsse zurückzuführen sind; hierzu gehören die Konstruktion der Rahmen, der Rahmenwerkstoff, das Verglasungsmaterial/ verfahren, die Einbaumethode, Luftdichtigkeit usw. Zur Klärung dieser Frage dürfen Messungen der Schalldämmung an vollständigen Fenstern (Scheiben und Rahmen) durchgeführt werden
Verre dans la construction - Vitrages et isolation aux bruits aériens - Descriptions de produits, détermination des propriétés et règles d'extension
Le présent document traite de la détermination et de l’évaluation des performances d’isolation acoustique de tous les produits verriers transparents, translucides et opaques décrits dans le document relatif aux produits de base, aux produits de base spéciaux ou aux produits en verre traité, lorsqu’ils sont destinés à être utilisés dans des ensembles vitrés dans des bâtiments, et qui présentent des propriétés de protection acoustique, que ce soit en première intention ou comme caractéristique supplémentaire.
Le présent document se réfère à la méthode de mesurage en laboratoire décrite dans l’EN ISO 10140 1:2016, Annexe D, et définit des règles d’extension pouvant être appliquées sans essais supplémentaires. Il indique également les données de performance type pour une gamme de produits verriers courants, qui peuvent être utilisées en l’absence de données mesurées.
Toutes les considérations du présent document font référence aux verres et produits verriers seuls. Leur incorporation dans des fenêtres peut modifier la performance acoustique en raison d’autres influences, par exemple la conception du châssis, le matériau du châssis, le matériau/la méthode de vitrage, la méthode de montage, l’étanchéité à l’air, etc. Des mesures de l’isolation acoustique de fenêtres complètes (verre et châssis) peuvent être entreprises pour résoudre ces questions.
Steklo v gradbeništvu - Steklo in izolirnost pred zvokom v zraku - Opis proizvoda, opredelitev lastnosti in pravila razširitve (vključno z dopolnilom A1)
Ta evropski standard dodeljuje vrednosti izolirnosti pred zvokom vsem proizvodom iz prozornega, prosojnega in neprozornega stekla, ki so opisani v evropskih standardih za proizvode iz osnovnega, posebnega osnovnega ali obdelanega stekla in kadar so namenjeni uporabi v zastekljenih sestavih na stavbah, pri tem pa izkazujejo lastnosti zaščite pred hrupom kot glavni namen ali pa dodatno lastnost.
Ta dokument določa postopek, s katerim je mogoče proizvode iz stekla oceniti glede na njihove akustične lastnosti, kar omogoča oceno skladnosti z akustičnimi zahtevami stavb.
Možna je tudi stroga tehnična analiza merilnih podatkov, vendar pa je ta standard namenjen omogočanju izpeljave enostavnejših indeksov zmogljivosti, ki jih lahko brez pomislekov sprejmejo nestrokovnjaki.
S sprejetjem načel tega standarda se poenostavi formulacija akustičnih zahtev v gradbenih predpisih in za specifikacije proizvodov, da se izpolnijo določene potrebe glede zasteklitve.
Znano je, da se postopki akustičnega preskusa iz standardov EN ISO 140-1 in EN ISO 140-3 navezujejo samo na steklene plošče in njihove kombinacije. Čeprav naj bi se enaka načela čim bolj upoštevala, se kompromisom ni mogoče izogniti zaradi zajetne konstrukcije drugih vrst zasteklitve, npr. steklenih blokov, tlakovnih enot, stekla v obliki kanala, strukturne zasteklitve in strukturne tesnjene zasteklitve. Smernice glede sprejetja preskusnih postopkov za te vrste zasteklitve so na voljo v točki 4.
Vsi vidiki tega standarda se navezujejo na plošče iz stekla/samo zasteklitev. Vgradnja v okna lahko spremeni akustične lastnosti zaradi drugih vplivov, npr. zasnove okvirja, materiala okvirja, materiala/metode zasteklitve, metode pritrditve, zračne neprepustnosti itd. Takšne težave je mogoče odpraviti z merjenjem izolirnosti pred zvokom pri celotnih oknih (steklo in okvir).

Overview
EN 12758:2019+A1:2023 - "Glass in building - Glazing and airborne sound insulation" is a CEN European Standard that assigns acoustic ratings to transparent, translucent and opaque glass products intended for use in glazed building assemblies. The standard defines a practical procedure to determine and declare the acoustic performance of glass panes, laminated glass and insulating glass units (IGUs), and provides extension rules and typical performance data so manufacturers, specifiers and non‑specialists can assess compliance with building acoustic requirements.
Key topics and technical requirements
- Scope: Covers basic, special basic and processed glass types when they provide acoustic protection either primarily or as a secondary characteristic. Applies to panes and glass products alone (not whole windows).
- Measurement basis: Refers to laboratory methods in EN ISO 10140 (notably Annex D) and rating in accordance with EN ISO 717‑1 (airborne sound insulation).
- Sound rating and indices: Uses Sound Reduction Index (R) and weighted indices (Rw) plus spectrum adaptation terms for application to different noise types (e.g., urban traffic, living activities).
- Extension rules: Provides rules to extrapolate acoustic performance from tested configurations to other product variants (e.g., thickness, coatings, interlayers) without repeating full tests.
- Processed products: Addresses treated glasses - strengthened, thermally toughened, laminated (including acoustic PVB interlayers), coated and insulating glass units (IGUs).
- Adaptation guidance: Offers guidance for adapting test procedures to bulkier glazing types (glass blocks, channel‑shaped glass, structural glazing) where laboratory protocols for simple panes are less directly applicable.
- Limitations: Notes that installation factors (frame design, sealing, mounting) affect in‑situ performance - recommending whole‑window testing where needed.
Practical applications and users
- Who uses it: Glass manufacturers, IGU and laminated glass producers, façade and window system designers, acoustic consultants, architects, building code writers and product certifiers.
- Practical uses:
- Declare product acoustic performance for product datasheets.
- Use extension rules to reduce testing burden when developing variants.
- Specify glazing to meet building acoustic requirements in specifications and codes.
- Provide baseline acoustic data for façade and window system acoustic design, with in‑situ verification of full assemblies if required.

SIST EN 12758:2019+A1:2023は、建物におけるガラスの音響絶縁に関する重要な標準です。この標準の範囲は、透明、半透明、および不透明なガラス製品の音響性能を評価し、建物のガラス装置で使用される際の特性を明確に定義することにあります。特に、音響保護の特性が主目的または補足的特性として求められる場合において、各製品に音響絶縁値が割り当てられます。 この標準の強みは、そのシンプルな性能指標を求める過程にあります。専門家でないユーザーでも自信をもって適用できるように設計されており、ガラス製品の音響パフォーマンスを評価するための手続きが明確に示されています。厳格な技術分析が可能であるにもかかわらず、簡易な評価を導出できることは、非専門家にとって大きな利点です。これにより、建築基準法における音響要件の定式化や、特定のニーズに応じた製品仕様の策定が簡素化されます。 また、この標準ではEN ISO 140-1及びEN ISO 140-3に関連する音響試験手順がガラス板の組み合わせに限定されている点も重要です。他のガラスの種類、たとえばガラスブロックやチャネル型ガラス、構造用ガラスなどでは、構造上の制約から妥協が避けられない場合もありますが、この標準にはそれらの試験手順に関する適応指針が提供されています。 SIST EN 12758:2019+A1:2023は、ガラスおよびガラス装置に特化したものであり、ウィンドウに組み込むと他の要因により音響性能が変化する可能性があることを認識しています。フレームデザインや材料、取り付け方法、気密性などの他の要因の影響を考慮し、完全なウィンドウ（ガラスとフレーム）の音響絶縁測定を実施することも推奨されています。 この標準は、建物における音響性能向上のための重要な基盤を提供しており、音響保護の実現において非常に関連性があります。音響絶縁性能を適切に測定し、実際の使用におけるインパクトを明確にするためのガイドラインを確立していることが、この標準の重要性をさらに高めています。
La norme EN 12758:2019+A1:2023 fournit un cadre exhaustif pour l'évaluation de l'isolation acoustique des produits en verre utilisés dans les bâtiments. Cette norme européenne est essentielle pour attribuer des valeurs d'insonorisation aux différents types de verre, qu'ils soient transparents, translucides ou opaques. Son énoncé clair permet une compréhension simplifiée des exigences acoustiques pour la conception de façades avec vitrage, facilitant l'application de ces normes par des professionnels non spécialistes. L'un des points forts de cette norme réside dans sa capacité à établir des indices de performance acoustique accessibles, tout en permettant une analyse technique rigoureuse des données de mesure. Cela permet d'évaluer la conformité avec les exigences acoustiques des bâtiments, en assurant que les produits en verre utilisés répondent à des standards élevés de protection acoustique. En adoptant les principes de cette norme, la formulation des exigences acoustiques dans les codes du bâtiment est clarifiée, ce qui améliore considérablement le processus de spécification des produits de vitrage pour des besoins spécifiques. Il est important de noter que, bien que les procédures d'essai acoustique standard décrites dans EN ISO 140-1 et EN ISO 140-3 concernent principalement les panneaux de verre, la norme EN 12758 intègre des lignes directrices pour adapter ces procédures pour d'autres types de vitrages, tels que les blocs de verre et les unitaires de pavé. Les compromis nécessaires lors de l'évaluation de ces types de vitrage sont abordés dans le document, ce qui démontre la flexibilité et l'application pratique de la norme dans des contextes variés. De plus, la norme rappelle que les considérations acoustiques se concentrent sur les panneaux de verre seuls.
