Standard – Annealed
Standard float glass which is generally used in Windows where there is not much requirement of thermal / Sound / Safety
Safety & Security – Toughened Glass & Sentry Glass
Toughened Glass is up to 5 times stronger than annealed glass of the same thickness. lt breaks into small pieces to reduce risk of serious injury.
Sentry Glass has ionoplast interlayers (from Dupont) which help create lighter, safer, more structural glass that can stand up to greater loads and higher threat levels. Taking advantage of the interlayer’s extra rigidity and toughness, structural glass systems — from floors and stairs to balcony rails and minimally supported glass canopies — can enjoy new design freedom.
Noise Control – Laminated Glass
With increasing traffic on the road, rail and in the air, noise insulation has become a very important topic. It is not a question of it being a luxury anymore it is essential that noise reduction is considered in the specification of the glazing. With regard to employment law, comfort and medical necessity, noise insulation in building construction is an undisputed requirement to decrease stress – and noise related illnesses. The desired acoustic performance can be achieved through combining various thicknesses of glass with a PVB interlayer.
Solar Control – Tinted, Reflective, IGU (Double Glass) & Low e
In winter, the fact that glass allows the sun’s heat as well as light into a building can be beneficial; but in summer months, without solar control it can become uncomfortably hot. Solar control glass provides a more comfortable environment, and can help to reduce the capital outlay, running costs and carbon emissions of a building throughout the year, by reducing or eliminating the requirement for air conditioning.
Given the variety of building designs and climatic conditions and the different levels of exposure to solar radiation during the year, the choice of glass must be able to protect the inside of the building to ensure maximum comfort, minimize energy consumption, guarantee safety and, not least, provide the optical and aesthetic qualities that satisfy the designer.
Solar control glass controls solar radiation by managing reflectance, transmittance and absorptance. For solar control purposes, and assuming solar radiation at near normal incidence, these are defined as:
Solar control can be achieved in a number of ways, including body-tinted glass, coated glass, laminated glass with tinted interlayers and IGUs.
