Why Winter Light Behaves So Differently in the UK Winter does not simply give a UK home fewer hours of summer-style light. The angle, duration and availability of sunlight all change. During winter, the sun remains much lower in the sky and the days become considerably shorter. That changes both which elevations receive direct sunlight […]

The Fundamental Difference: Direct Sun Versus Diffuse Daylight North- and south-facing windows can use exactly the same glass and still create very different conditions inside a home. The reason begins with the path of the sun. In the UK, the sun travels predominantly across the southern part of the sky. A south-facing elevation therefore has […]

North, South, East and West: What Actually Changes? The direction a window faces changes when sunlight reaches it, the angle at which that sunlight arrives and how solar exposure varies throughout the day. That means two identical panes of glass on different elevations can create very different conditions inside the same home. South-facing glazing can […]

What Is Actually Between the Panes of Double and Triple Glazing? Look closely at a modern double-glazed window and the space between the panes can appear to contain nothing at all. But that apparently empty space is an important part of the glazing specification. Double glazing uses two panes of glass separated by a controlled […]

What Is the Spacer Inside Double or Triple Glazing? Look closely at the perimeter of a double-glazed unit and you will usually see a narrow strip running between the panes. That component is the spacer. Its most obvious job is contained in its name: it maintains a controlled distance between the individual panes of glass, […]

What Is Acoustic Laminated Glass? Acoustic laminated glass is designed to reduce the transmission of sound through glazing more effectively than a conventional glass construction selected without a specific acoustic objective. Like other laminated glass, it consists of two or more glass plies bonded together with an interlayer. In an acoustic laminate, a specialist interlayer […]

What Do We Actually Mean by Switchable Glass? “Privacy glass” can describe several very different products, so the terminology needs to be understood before deciding whether any of them are appropriate for a home. At its simplest, privacy glass can mean conventional glass that is permanently obscured. Frosted, etched or patterned glass allows light through […]

How Self-Cleaning Glass Actually Works The name “self-cleaning glass” can make the technology sound more dramatic than it really is. The glass does not actively clean itself, and there is no hidden mechanism removing dirt from the surface. Instead, a specialist coating changes the way certain deposits and water behave on the external face of […]

What Is Ultra-Clear Glass? Ultra-clear glass is designed to provide greater visual clarity and colour neutrality than conventional clear glass. The difference comes primarily from the raw material itself: ultra-clear glass is manufactured with a lower iron content, reducing the characteristic green cast naturally present in standard clear glass. That distinction is important because “clear” […]

What Solar Control Glass Actually Does Solar control glass is designed to reduce the amount of solar energy passing through the glazing and contributing to heat inside the building. That becomes particularly relevant where architecture uses large areas of glass to bring in daylight, open up views and create a stronger connection with the landscape. […]

Where the Green Colour in Glass Comes From Glass is transparent, but that does not mean it is completely colourless. Standard clear architectural glass naturally has a subtle green appearance, and the main reason is the small amount of iron present within the raw materials used to manufacture it. For most conventional windows, this colour […]

The Fundamental Difference: What Happens When the Glass Breaks? The clearest way to understand the difference between toughened and laminated glass is not simply to ask which one is stronger. It is to ask a more useful question: what happens if the glass actually breaks? Toughened glass has undergone a controlled heat-treatment process that changes […]

What Is a Low-E Coating? Low-E stands for low emissivity. In practical terms, a low-E coating is an extremely thin engineered layer incorporated into the glazing to help reduce the transfer of radiant heat through the glass. It can have a significant influence on thermal performance while remaining visually subtle within the finished window or […]

What Does “Tolerance” Actually Mean in Glazing? In architectural glazing, tolerance describes the dimensional variation that needs to be anticipated when different parts of a building come together. A drawing may show an opening with precise dimensions and perfectly straight lines, but the physical building is assembled from structural steel, masonry, concrete, timber, finishes and […]

Why Would Glass Need to Be Craned in the First Place? Large-format glazing does not automatically require a crane. Many substantial glass units can be installed using other professionally determined handling methods, depending on their dimensions, weight and the conditions of the site. Specialist lifting becomes relevant when the combination of the glass itself and […]

Large Glass Is Not Delivered Like an Ordinary Window Oversized architectural glazing may look remarkably simple once installed, but getting it into position can be a significant construction exercise. As panels become larger, they generally become heavier and more demanding to handle, changing the way they need to be transported, unloaded and moved around the […]

What Does Deflection Actually Mean? Deflection is the term used to describe the movement or bending of a structural element when it is subjected to load. A steel beam spanning above a large sliding-door opening may appear completely rigid, but in structural terms it is not necessarily motionless. As loads are applied, a degree of […]

A Structural Opening Is Not Just a Hole for the Glass One of the most common misconceptions with large-format glazing is that the structure can be designed first and the glass simply made to fit the opening afterwards. At a basic level, that sounds reasonable: the engineer establishes a structurally suitable opening, the steelwork is […]

A Corner Is Not Just Something That Gets in the Way of the View When designing a highly glazed extension or contemporary home, it is easy to see the corner as an obstruction. Two large areas of glass might offer an uninterrupted view of the garden or landscape, only for a vertical post at their […]

What Does “Corner Glazing Without a Post” Actually Mean? One of the most common misconceptions around postless corner glazing is that the corner is somehow constructed without a frame or supporting structure. In reality, “postless” usually describes what we see rather than everything that is happening within the construction. A conventional glazed corner typically uses […]

The Problem Usually Starts With a Good Idea Rooflight overheating rarely begins with an obviously unreasonable design decision. More often, it begins with something entirely desirable: a brighter interior, a stronger connection with the sky and more daylight reaching parts of a home that conventional windows cannot easily serve. Consider a typical contemporary extension. Large […]

A “Flat” Rooflight Still Has to Manage Water The word flat can create a misleading impression when discussing rooflights. Architecturally, a flat rooflight may appear as a simple sheet of glass sitting almost effortlessly within the roof. Rainwater, however, still needs somewhere to go. The visual simplicity of the finished glazing does not remove the […]

Daylight From Above Behaves Differently Daylight entering through a roof does not behave in quite the same way as daylight entering through a wall. A conventional window creates an outward relationship, connecting the interior with a garden, street or landscape beyond. Its view is predominantly towards the horizon. A rooflight turns that relationship upwards, introducing […]
