Three Panes Sounds Better Than Two — and Sometimes It Is Triple glazing has an appealing simplicity to it. If two panes of glass provide insulation, three must surely provide more. For homeowners already investing heavily in a renovation or self-build, choosing the apparently higher specification can feel like an obvious decision: improve the glazing […]

Warning Sign One: Rooms Feel Draughty Around the Windows A room can be warm according to the thermostat and still feel uncomfortable beside a window. That experience is often described simply as a draught, but the sensation does not always identify the problem as neatly as the word suggests. There may be unwanted air movement […]
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 […]
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 […]
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 […]
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 […]
Regret #1: Focusing On Products Instead Of Outcomes One of the most common regrets homeowners have after a glazing upgrade begins long before any windows or doors are ordered. It starts with the way the decision is approached. Many glazing projects begin with products. Homeowners compare frame materials, explore different manufacturers, review sightline dimensions and […]
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 […]
