GGF launches 21 new and updated Data Sheets

The GGF has new and updated Data Sheets available specifically targeted at ensuring members are fully up to date with the correct technical information and latest guidance.

For the first time there is now a complete set of curved glass Data Sheets, which provide advice on all the types available, annealed, thermally treated, laminated an insulating units.The publications deal with complex shape requirements and tolerances through to safety performance requirements and visual quality.

In line with the safety requirements of BS ISO 11485-3 the latest Data Sheets explain the testing and performance necessary to classify curved safety glass within the UK.  Importantly the claim for manufacturers and installers of curved safety glass is included, with the steps required for members to comply, giving end users complete confidence in the final safety performance.

Updated Data Sheets in Section 4:

4.12.1 Curved Glass Part 1: Generalities - Terminology, Properties and Basis of Measurement and Test (link)

4.12.2 Curved Glass Part 2: Curved Annealed Glass (link)

4.12.3 Curved Glass Part 3: Curved Thermally Treated Glasses (link)

4.12.4 Curved Glass Part 4: Curved Laminated Glasses (link)

4.12.5 Curved Glass Part 5: Curved Insulating Glass Units (link)

Following publication of EN 15752-1 and EN 15755-1 the whole suite of Data Sheets providing advice, testing and installation of adhesive backed polymeric films has been revised and updated.  Particular attention has been given to water quality during installation, cure times and preparation of the glass surfaces to be filmed.

Data Sheet 5.16.1 has also been revised, and details all appropriate optical and visual quality factors of fire-resistant glass, used either as single panes or incorporated into an IGU.

Updated Data Sheets in Section 5:

5.16.1 Appearance and Visual Quality Specification for Fire-Resistant Glass and Insulating Glass Units (IGUs) Incorporating Fire-Resistant Glass (link)

5.18.1 Visual Quality for Adhesive Backed Polymeric Filmed Glass (link)

5.18.2 Installation Quality Standard for Applying Adhesive Backed Polymeric Film to Glass (link)

5.18.3 Recommendations for Adhesive Backed Polymeric Film Applied to Glass: Definitions, Descriptions and Components (link)

5.18.4 Recommendations for Adhesive Backed Polymeric Film Applied to Glass in the Overhead Position for Containment of Glass in the Event of Failure: Types of Systems and Precautions in Use (link)

5.18.5 Recommendations for Adhesive Backed Polymeric Film Applied to Glass in the Overhead Position for Containment of Glass in the Event of Failure: Test Method (link)

5.18.6 Recommendations for Blast Mitigation: Adhesive Backed Polymeric Film Applied to Glass (link)

5.18.7 Standard for On-Site Peel Adhesion Testing of Aged Adhesive Backed Polymeric Film Applied to Vertical Flat Glass (link)<

5.18.8 Adhesive Backed Polymeric Film Guidelines for Installation onto Existing Glazing (link)

Following the revision of GGF Data Sheet 4.4.1 for thermally treated soda lime silicate glass products, two new publications complete the suite of latest information and advice available, which include spontaneous breakage and interference phenomenon.  As larger and higher performing glass types are used, effects such as anisotropy or iridescence are sometimes more noticeable.  This Data Sheet details the features of anisotropy, the effects of incident polarised light and viewing angles necessary to highlight this particular phenomenon.

Updated Data Sheets in Section 4:

4.4.1 Thermally Treated Soda Lime Silicate Glass Products – General (link)

4.4.2 Thermally Treated Soda Lime Silicate Glass Products - Spontaneous Breakage (link)

4.4.3 Thermally Treated Glass: Appearance - Interference Phenomenon (link)

Steve Rice, GGF Director of Technical Affairs commented: “Revised and updated Data Sheets in line with the latest British, European and International standards gives a welcome boost the technical knowledge and best industry advice available to our members and to the broader glass and glazing industry.  With the recent introduction of approved document Q, Members also have access to whole suite of security glazing Data Sheets with the 8.1 series.  As security concerns and terrorism threats increase technical advice is crucial in reducing harm or damage to people in property. This new information will help mitigate the effects of manual attack, firearms attack, and blast resistance.”

Updated Data Sheets in Section 8:

8.1.1 Security Glazing - Part 1: Definitions and Description (link)

8.1.2 Security Glazing - Part 2: Manual Attack Resistant Glazing (link)

8.1.3 Security Glazing - Part 3: Bullet Resistant Glazing (link)

8.1.4 Security Glazing - Part 4: Explosion Resistant Glazing (link)

8.1.5 Security Glazing - Part 5: Framing and Installation (link)
