At Viracon we continually strive to help our customers in as many ways as we can. Tech Talks provide educational information about individual architectural glass topics.
Glass facades deliver many benefits including daylight, views and dynamic aesthetics. A counterpoint is that birds do not perceive glass as an obstacle to their flight path. This document provides information to balance glass benefits with the adverse impact on birds.
When using silk-screen, spandrel or DigitalDistinctions™ in architectural building applications, the design details require careful consideration to avoid an unintended aesthetic result such as a moiré pattern or an uneven, checkerboard appearance. Moiré is an optical phenomenon that typically appears as a wavy, rippled or circular pattern.
The appearance and performance of an existing glass façade can be altered by applying a film or coating to the glass. There are risks associated with the use of such films and coatings, including glass breakage or incompatibility. This document provides items that should be considered prior to applying a coating or film to glass.
Overall, flat glass for commercial buildings is uniquely resistant to chemical attacks and other types of deterioration. However, glass staining can occur from a reaction to acids used during new concrete cleaning, masonry runoff and prolonged water contact during storage and shipment.
Fully tempered glass is susceptible to spontaneous breakage due to the presence of nickel sulfide inclusions. To mitigate the risk of breakage, fully tempered glass can be heat soak tested. This document outlines the process and benefits associated with heat soak testing.
The use of insulating glass continues to grow worldwide as a result of the desire to build more energy efficient buildings. The various types of glazing systems utilized today require insulating glass units to be accommodating in their structural characteristic as well as the visual aspects of the unit.
Strain patterns, sometimes referred to as iridescence, anisotropy or quench patterns, are an inherent characteristic of heat treated glass. This document describes how strain patterns form as well as expected visual characteristics.
The solar spectrum encompasses all energy coming from the sun and is made of three components; visible, infrared and ultraviolet. Visible is light you see when looking at the sun, infrared is the heat you feel on your skin and ultraviolet fades fabrics and deteriorates plastic.
Glass breakage can occur for several reasons; one of which is thermal stress. This document provides information about how to identify and minimize thermal stress glass breakage.
Glass viewing windows in swimming pools and aquariums are subjected to hydrostatic pressures. This document provides guidance for selecting the appropriate glass type and thickness based on the specific hydrostatic pressure to which the glass will be exposed.
The following video provides an overview of daylighting and glass selection.
