Heat Treated Glass – Features and Flaws

Books can and have been written on this topic but hopefully this extremely summarised account will enlighten some.

To increase the strength of float glass we can heat treat it. There are 2 levels of treatment covered under the current standards. Heat Strengthened and Toughened (also known as Fully Tempered). Strengthened glass increases the strength of the glass by 2 and Toughened increases it by 4 to 5 times compared to annealed glass of the same thickness. Of the 2 only Toughened glass is classified as a class A safety glass.

Thermal Fracture in Glass Units

Thermal fracture is the name given to glass breakages that occur due to high ranges of temperature variation within the glass unit. When areas within a glass unit heat up faster and to a higher temperature than other areas within the same unit then it will lead to increased stresses with in a unit and the chance of the glass cracking increases.

Assessing the Visual Appearance and Acceptability of Glass

Traditionally in the UK glass in commercial buildings has been assessed in line with TN 35 published by the CWCT, GGF Guidelines, Hadamar and various BS EN standards. These documents define inspection methodology in terms of viewing distance and angle and crucially what is or isn’t considered to be a defect.

Effect of floor slab movement on system selection

Glazing and cladding systems need to be designed to allow for building movements without compromising the performance or safety of the system. Therefore, the effects of building movements on the glazing system selection needs to be considered at the early planning stage of a project to ensure that the correct glazing system is specified.
