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 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 […]

Why Slimmer Does Not Automatically Mean Colder It is easy to assume that making a glazing frame slimmer must come at the expense of thermal performance. The reasoning appears intuitive: if there is less visible frame around the glass, there must surely be less material available to resist heat transfer. In practice, however, sightline and […]

Understanding How Modern Glazing Is Constructed To understand why moisture can appear between the panes of a window, it is helpful to first understand how modern glazing is constructed. Although double and triple glazing may appear to be simple assemblies of glass, they are in fact carefully engineered insulated glazing units designed to improve thermal […]

While these characteristics are often associated with Passivhaus buildings, they are not what defines the standard. At its heart, Passivhaus is a design philosophy centred on creating homes that […]

Triple Glazing Isn’t Automatically the Right Answer One of the most common misconceptions surrounding modern glazing is that triple glazing is always the superior choice. It is an understandable assumption. Three panes of glass sound inherently better than two, and as energy efficiency has become a greater priority for homeowners, triple glazing has increasingly been […]

Why Every Home Saves a Different Amount One of the most common questions homeowners ask is, “How much will new windows save me on my energy bills?” It is an understandable question, but it does not have a single answer. Unlike replacing an old appliance with one that has a published energy rating, the impact […]

What a U-Value Actually Measures U-values are often presented as one of the most important numbers when comparing windows and doors, yet they are rarely explained in a way that makes sense to homeowners. The term itself sounds highly technical, leading many people to assume it requires specialist knowledge to understand. In reality, the concept […]

What “Energy-Efficient Glazing” Actually Means The term energy-efficient glazing appears everywhere—from manufacturer websites and product brochures to renovation programmes and property listings. Yet despite its widespread use, it is often misunderstood. Many homeowners assume it simply means thicker glass or additional panes, while others believe any new window will automatically deliver exceptional energy savings. In […]

What A U-Value Actually Measures A U-value is one of the most commonly quoted performance figures in the glazing industry. It appears in brochures, technical documents, building regulation discussions and sales conversations. Yet despite how often it is used, many homeowners are never given a clear explanation of what the number actually means. In simple […]

Why Purchase Price Dominates The Decision When homeowners compare window quotations, the purchase price is usually the first figure they notice. It is clear, immediate and easy to compare. One quotation is higher, another is lower, and the difference can feel significant, especially on a larger renovation, extension or self-build project where costs are already […]

More Glass Does Not Automatically Mean Better Performance One of the reasons triple glazing has become so widely recommended is that it appears to offer a simple upgrade path. If double glazing consists of two panes of glass and triple glazing consists of three, it seems logical to assume that triple glazing must always perform […]
