Red Flag One: You Cannot Tell Exactly What Window Has Been Quoted A window quotation can contain a great deal of information and still leave the most important question unanswered: what, precisely, is being proposed? A product name and overall dimensions may create an impression of specificity, but they do not necessarily reveal enough about […]

First Decide What You Are Trying to Protect Reducing a glazing budget becomes much easier once there is agreement about what the glazing is supposed to achieve. On one project, the priority may be an uninterrupted view across the garden. On another, it may be thermal comfort, generous daylight or the ability to open a […]
Start With the House, Not the Window Catalogue The most effective way to reduce the cost of windows is often to make better decisions before choosing them. It is easy to begin with materials, brands and individual prices, but those comparisons come relatively late in the process. By then, the architecture may already have determined […]
The Biggest Underestimate Is Usually the Specification, Not the Window When a glazing budget begins to move, it is tempting to assume that the windows themselves have simply become more expensive. Often, the explanation is more complicated. An early allowance may have been established when the project consisted of preliminary drawings, approximate opening sizes and […]
Why Two Similar-Looking Windows Can Cost Very Different Amounts At first glance, the difference between a moderately priced window and one costing £1,200 can be surprisingly difficult to see. Both may have double or triple glazing, similar dimensions and frames that appear broadly comparable. Once installed, particularly when viewed from several metres away, there may […]
The First Price Is Not Always the Final Cost The price paid for windows and doors at the beginning of a project is only one way of measuring their cost. Glazing becomes part of the fabric of a building, which means that changing it later can involve far more than purchasing a second set of […]
£30,000 Is a Budget, Not a Glazing Specification A budget of £30,000 sounds precise. In architectural glazing, however, it does not describe a particular quantity of windows, a certain size of sliding door or a predetermined level of specification. It establishes a financial boundary. What happens within that boundary depends on the architecture. Two projects […]
The Window or Door System You Are Actually Buying The first line to understand in any glazing quotation is the most fundamental: what window or door system are you actually being offered? Descriptions such as “aluminium window”, “sliding door” or even the dimensions of an opening do not provide enough information to establish that two […]
The Same Drawings Do Not Always Produce the Same Specification When two glazing companies receive the same architectural drawings, it is natural to assume they are pricing the same job. Often, however, the drawings establish the size and position of the openings without defining every decision required to turn those openings into manufactured windows and […]
Start With the Glazing as a Complete System An annual review of architectural glazing is most useful when it begins with the whole opening rather than an individual pane of glass. A window or glazed door is an assembly in which glass, frames, seals, hardware and, where relevant, tracks and thresholds work together. Looking at […]
Glazing Lives at the Most Exposed Part of the Building Windows and glazed doors occupy a demanding position within the architecture of a home. They form part of the boundary between a relatively controlled interior and an external environment that changes continuously. Across the seasons, frames, seals and surrounding components encounter variations in temperature, moisture, […]
A Glazing Guarantee Is Rarely One Simple Promise A glazing guarantee can sound reassuringly straightforward. A particular period is quoted, the installation is described as guaranteed, and it is easy to assume that every element of the finished glazing carries the same protection. In practice, a substantial window or door installation can contain several distinct […]
Start With Access, Not Cleaning Products With large architectural glazing, the first consideration should not be which cleaning product to use, but whether the glass can be reached safely in the first place. Floor-to-ceiling windows, tall fixed panes and expansive glazed elevations can appear straightforward from inside a room, yet their external surfaces may sit […]
Why Winter Reveals More About Your Glazing Windows and glazed doors form part of the boundary between two very different environments, and winter makes that role particularly noticeable. As external temperatures fall and heating keeps the interior warmer, the difference between conditions inside and outside becomes greater. Add stronger winds, prolonged rain and higher levels […]
Glass Is Not the Architecture — It Serves the Architecture Large areas of glass have become closely associated with contemporary residential architecture. It is easy to understand why. Glazing can bring daylight deep into a home, create a stronger relationship with the landscape and give rooms a sense of openness that would be difficult to […]
The Best Glazing Trend May Be Not Looking Trend-Led When planning a major renovation or new home, it is natural to want the finished building to feel contemporary. The difficulty is that what feels current today can become the detail that dates the building tomorrow. Glazing is particularly exposed to this cycle. Frame colours become […]
The Glazing Project Starts Before Anyone Chooses a Window An architectural glazing project rarely begins with a product. It begins with an idea about how the building should feel and function. At the earliest design stage, the important questions are usually architectural. Where should daylight enter the building? Which views deserve to be framed? How […]
Forty Years Is a Design Question, Not a Warranty Claim Architects routinely design homes expected to remain useful for many decades. Yet glazing decisions can become dominated by what happens at the beginning of that life: how the system looks, whether it meets the current performance requirements, what it costs and how successfully it delivers […]
The Most Important Glazing Decisions Often Happen Before a Product Is Chosen One of the most useful distinctions in architectural glazing is the difference between designing the glazing and selecting the product. Homeowners often associate the glazing decision with choosing a manufacturer, comparing frame materials or deciding between particular window and sliding-door systems. By the […]
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 […]
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 […]
