What Does Supply-Only Actually Mean? The term supply only is frequently used within the glazing industry, yet it is often misunderstood by homeowners comparing quotations for windows and doors. While it may appear to describe a simpler or more affordable purchasing option, it actually refers to a distinct procurement route in which the supplier provides […]

Why Price Is Only One Part of the Decision When homeowners receive several glazing quotations, it is entirely understandable that the first comparison is often the final figure at the bottom of the page. Price provides an immediate and measurable point of reference, particularly when the quotations appear to describe similar products. However, architects rarely […]
Why Two Quotes Rarely Cover the Same Thing Receiving several quotations for a window project is often recommended as a sensible way to compare options and understand the market. Yet many homeowners quickly discover that the proposals they receive differ considerably, not only in price but also in the products, terminology and levels of detail […]
Why Every Window Project Costs Something Different One of the most common questions homeowners ask at the beginning of a renovation or self-build project is, “How much will my new windows cost?” It is an entirely reasonable question, yet one that rarely has a simple or meaningful answer. Unlike many household purchases, architectural glazing is […]
Why Every Building Site Is Different No two building sites are exactly alike, and neither are the environmental conditions that shape the performance of a building over time. While it is easy to think of glazing as a standard element that can be selected from a catalogue, architects approach specification from a very different perspective. […]
What a Window Seal Actually Does When people think about windows, their attention naturally focuses on the visible elements: the glass, the frame or the overall design. Yet one of the most important components is almost entirely hidden from view. The perimeter seal around an insulated glazing unit performs a critical role in maintaining the […]
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 […]
Why Good Glazing Is Difficult to Judge at First Glance One of the most persistent misconceptions in residential architecture is that high-quality glazing can be recognised simply by looking at it. Modern manufacturing has made it possible for products at very different levels of engineering and performance to share remarkably similar visual characteristics. Slim sightlines, […]
Not Every Draught Comes Through the Window Feeling a movement of air near a window can understandably lead homeowners to conclude that the window itself is letting cold air inside. In many cases, however, the source of that sensation is more complex. Buildings are constantly responding to differences in temperature, air pressure and ventilation, creating […]
Comfort Is About More Than Temperature When homeowners think about improving the comfort of their home, attention often centres on insulation, heating efficiency and reducing energy bills. While these are all important considerations, comfort is shaped by far more than temperature alone. The sounds that enter a home throughout the day—from passing traffic and aircraft […]
Protection Starts Before Anything Is Ordered When homeowners invest in premium glazing, it is natural to assume that protecting it begins on installation day. Frames are carefully handled, glass is lifted into place and protective coverings are applied while construction continues. Although these steps are important, architects understand that the real protection begins much earlier. […]
Matching Doesn’t Mean Copying When planning a new-build wing alongside an older property, many homeowners assume the safest approach is to make every window and door identical. If the original house has traditional timber casements, should the extension copy them exactly? If the existing façade follows a particular pattern, should the new addition simply repeat […]
Great Architecture Starts With Light, Not Windows When homeowners begin thinking about glazing, their attention naturally turns to windows. They compare frame materials, opening styles, sightlines and product ranges, assuming these choices are where good design begins. Architects approach the process from an entirely different direction. Before they think about windows, they think about light. […]
Windows Influence the Design From Day One Many homeowners begin a renovation believing that windows are one of the final decisions to make. The assumption is understandable. After all, windows are installed relatively late in the construction process, so it seems logical to choose them once the structure is taking shape. Architects approach renovations very […]
Window Planning Starts Before Planning Permission One of the most common misconceptions in self-build projects is that windows can be chosen once the structure has been designed or, worse still, once construction is already underway. Architects rarely work this way. Long before planning permission is submitted, glazing is already helping to shape the architecture. Decisions […]
The Biggest Glazing Decision Is Where It Goes When homeowners begin planning an extension, the conversation about glazing often starts with products. Should the project include sliding doors, bifold doors or fixed glass? Which frame material is best? How large can the panes be? While these are important questions, architects rarely begin there. They know […]
Section 1: The Frame Material Is Only One Part of the Cost When homeowners first begin researching aluminium windows, one assumption appears again and again: “They’re expensive because aluminium is expensive.” It seems like a logical conclusion. After all, if the frame is made from metal rather than uPVC, surely the material itself must account […]
Section 1: Aluminium Doesn’t Rot, Warp or Rust Like Many People Assume When homeowners ask how long aluminium windows last, they are often looking for a simple number. Twenty years? Thirty years? Forty years? While those figures can provide a useful indication, they do not explain why aluminium has become one of the most trusted […]
Section 1: Performance Starts Long Before Energy Ratings When homeowners begin comparing aluminium and uPVC windows, one specification often dominates the conversation: the U-value. Energy ratings have become one of the most familiar ways of judging modern glazing, leading many people to assume that the window with the lowest published figure must automatically be the […]
Section 1: What Are Window Sightlines? When homeowners begin comparing aluminium windows, conversations usually focus on frame colours, glazing performance, security or energy efficiency. Sightlines are rarely the first topic discussed, yet architects often notice them almost immediately. In fact, the width and proportion of a window’s visible frame can have a greater influence on […]
Section 1: The Problem: Aluminium Is Extremely Good at Conducting Heat Aluminium has become one of the defining materials of contemporary architecture. Its strength, durability and ability to support slim, elegant frames make it an obvious choice for modern windows and doors. Yet aluminium also possesses one characteristic that once limited its use in residential […]
Section 1: Why Two Materials Can Be Better Than One When homeowners first encounter alu-clad windows, they often assume they represent a compromise between timber and aluminium. The name itself can create the impression that one material has simply been added to another as a protective layer. Architects see the concept rather differently. They do […]
Section 1: Have You Agreed the Right Specification—Not Just the Right Product? Paying a deposit often feels like the point where a glazing project becomes official. The decisions appear to have been made, the products selected and the installation begins to feel real. Yet architects rarely think of this stage as simply ordering windows and […]
Section 1: Don’t Start by Comparing Quotes—Start by Comparing Expertise When homeowners begin looking for a glazing supplier, the first comparison is often price. Quotations are gathered, specifications are skimmed and attention naturally focuses on the figure at the bottom of the page. It is an understandable approach, particularly when glazing represents a significant investment […]
