We do not make up topics just to get clicks. Our topics come from the questions people really ask us. Architects ask us when they plan a building. Builders ask us on-site. Homeowners ask us when they plan their project. If the same question keeps coming up, we write about it.
02
The first draft is written by someone who works with that glazing system. This might be a technical advisor, a designer, or a product expert.
They write using three things, in this order. First, our own finished projects and what we learned from them. Second, the building rules and the glass standards that apply. Third, the maker's technical data for the system we supply. When we give a number or a limit, we say where it comes from. We name the rule or standard and link to the official source so you can check it yourself.
03
Before any article goes live, a second qualified person reads it. They check three things. That the facts are right and not made too simple. That any rule or standard we mention is current and stated correctly. That the advice matches how the work is really done on site.
This checker can send the article back, ask for proof, or stop it from going live. Two experts must agree. This is the most important safety step in how we work. The name of the person who checked each article is shown on the article itself.
04
Each article shows who wrote it, who checked it, and the date it was last checked. Rules, standards, and products change over time. So we go back and review our advice on a regular basis. We update it when a rule changes, a standard is replaced, or a product changes. Being right matters more than leaving an old article alone.
Architectural glazing has become increasingly popular in modern architecture. This technique, involving the use of glass in building exteriors and interiors, marries aesthetic appeal with functional benefits. Architectural glazing not only transforms the visual dynamics of structures but also enhances their performance in energy efficiency, security, and comfort. Our glazing team at IQ Glass has put together this article to teach you everything you need to know about architectural glazing, its capabilities and why it's so popular for architectural projects.
Architectural glazing refers to the use of glass as a significant component in building design, valued for both its structural properties and aesthetic appearance. It serves multiple purposes, such as allowing natural light to flood interiors, providing thermal and acoustic insulation, and offering unobstructed views of the property's surroundings. Unlike conventional windows, architectural glazing often involves advanced glass technologies and innovative design solutions, making it a sophisticated element in modern architecture.
Architectural glazing can be found in various settings, from residential homes to skyscrapers, where it plays a crucial role in enhancing the building's overall visual appeal and performance.
The history of architectural glazing is marked by significant advancements and innovations. Early uses of glass in architecture date back to Roman times and became more popular during the Industrial Revolution with the development of plate glass. The 20th century saw further innovations with the introduction of float glass and insulated glazing units (IGUs), which improved both the quality and affordability of architectural glass. More recently, advancements like low-emissivity coatings, laminated glass, and smart glass have pushed the boundaries of what architectural glazing can achieve. At IQ Glass our architectural glazing experts we are at the forefront of this innovation.
Double glazing consists of two glass panes separated by a spacer filled with air or gas, enhancing thermal insulation. This type of glazing is widely used in residential and commercial buildings for its ability to reduce heat loss, improve energy efficiency, and increase comfort by minimising drafts and cold spots.
Triple glazing includes three layers of glass which helps to provide a superior thermal performance, especially in colder climates. The additional pane and insulating layer offer significant energy savings and enhanced indoor comfort.
Low-emissivity (Low-E) glazing features a special coating that reflects infrared radiation while allowing visible light to pass through. This enhances insulation and energy efficiency, making it an excellent choice for reducing energy consumption and improving indoor comfort.
Laminated glazing consists of two or more layers of glass bonded with an interlayer, typically made of polyvinyl butyral (PVB). This type of glazing provides enhanced safety and security, as the interlayer holds the glass together even when shattered, reducing injury risk and providing better home security when looking at glass options specifically.
Tempered glazing, also known as toughened glass, is heat-treated to increase its strength and durability. When broken, it shatters into small, blunt pieces, reducing injury risk. This makes it ideal for areas where safety is a concern, such as doors, windows, and facades.
There are a lot of considerations when buying Architectural glazing, here are some of the main benefits you should consider;
Architectural glass significantly contributes to energy savings by improving the thermal performance of buildings. High-performance glazing reduces the need for artificial heating and cooling. This helps to lower energy bills and reduce greenhouse gas emissions.
Likely to be the most popular reason for its use, Architectural glazing offers unparalleled design flexibility, enabling architects to create stunning, light-filled spaces that blur the line between indoors and outdoors. The sleek, modern look of glass transforms the appearance of any structure, adding sophistication and elegance. Take a look at some of the stunning architectural glazing projects by IQ Glass.
Glazing allows natural light to penetrate deep into interiors, creating bright and inviting spaces. This not only enhances visual appeal but also improves occupants' well-being, as natural light is known to boost mood and productivity.
In less remote and private environments, noise pollution can be a common concern. Architectural glazing as a bonus solution provides excellent acoustic insulation, with laminated and double-glazed units effectively reducing external noise and creating quieter, more comfortable indoor environments for your family and friends to enjoy.
In homes, architectural glazing is used in windows, doors, skylights, and conservatories. It enhances the living experience by providing natural light, insulation, and a connection to the outdoors. Homeowners enjoy panoramic views, increased property value, and a modern aesthetic. Some of the most popular applications of architectural glazing in a residential environment include roof glazing.
Commercial building projects require a fully bespoke solution. Projects such as office complexes, shopping centres, and hotels, benefit greatly from architectural glazing. It improves energy efficiency and comfort while creating visually striking facades that attract visitors and clients. Glazed atriums, structural curtain walls, and storefronts are common applications.
Public buildings, including schools, hospitals, and museums, utilise architectural glazing to create functional and welcoming spaces. Glazing improves daylighting, reduces energy costs, and enhances the overall environment, making these facilities more pleasant and efficient.
Various types of glass are used in architectural glazing, each offering unique properties and benefits. These include float glass, low-iron glass for clarity, tinted glass for solar control, and coated glass for energy efficiency. The choice of glass depends on project requirements, such as thermal performance, safety, and aesthetics.
Frames and supports used in architectural glazing are crucial elements not to be overlooked. Common materials include aluminium, steel, and uPVC, each offering different levels of strength, durability, and thermal performance. The choice of frame material impacts the overall performance and appearance of the glazing system and should therefore be purposefully chosen.
Understanding the different types of architectural glass available is crucial for selecting the right solution for any project. Here are some common types of architectural glass used today:
Smart glass allows dynamic changes in its properties, including adjusting tint, opacity, or thermal properties in response to environmental conditions or user preferences. It's used in privacy windows, sunroofs, and energy-efficient buildings.
Solar control glass reduces the amount of solar heat entering a building while maintaining high levels of natural light transmission. This type is beneficial in hot climates, helping to reduce cooling loads and improve comfort.
Electrochromic glazing, also commonly referred to as "dynamic glass," uses a thin layer of electrochromic material that changes opacity with electrical voltage. This allows precise control over light and heat entering a building, offering significant energy savings and enhanced comfort.
Maintaining architectural glazing's performance and appearance requires regular cleaning and inspection. We recommend using non-abrasive materials and appropriate cleaning agents to avoid damaging the glass and frames. Regular inspections help identify signs of wear or damage, such as cracks, condensation, or seal failure.
Common issues like condensation, cracks, and seal failure should be promptly addressed to prevent further damage and maintain performance and quality. Condensation can be mitigated by improving the ventilation, while cracks and seal failures typically require professional repair or replacement.
While regular cleaning and minor repairs can be performed by building owners, professional maintenance services offer several advantages. Professionals have the expertise and tools to conduct thorough inspections, identify potential issues early, and perform high-quality repairs, ensuring the glazing system's longevity and performance.
Iconic buildings like The Shard in London and the Louvre Pyramid in Paris showcase architectural glazing's potential. These structures exemplify how glazing can create modern architectural marvels and highlight its aesthetic and structural capabilities.
