Why Do New Windows Feel Colder After Sunset? New windows can feel noticeably colder after sunset, even when they are performing exactly as intended. During daylight hours, sunlight passing through the glazing can contribute warmth to a room, while solar radiation may also increase the temperature of the glass and surrounding surfaces. As daylight fades, […]

Is Replacing Windows One Room at a Time a Sensible Approach? Replacing every window in a property at the same time is not always necessary, nor is it necessarily the most appropriate approach to a renovation. For homeowners managing a limited budget, living through building work or improving a property over several years, replacing windows […]
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 […]
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 […]
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 […]
Why Replacing Walls With Glass Changes the Room Completely A glass wall may visually disappear, but environmentally it behaves very differently from the insulated wall it replaces. That distinction becomes increasingly important as the amount of glazing grows. An opaque external wall is primarily designed to separate the internal environment from external conditions. Architectural glazing […]
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 […]
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 […]
Why Windows Often Receive Too Much—and Too Little—Attention Few elements of a home renovation attract as much attention as new windows. They are among the most visible investments homeowners make, they can transform the appearance of a property and they are frequently promoted as a solution to rising energy costs. At the same time, their […]
Passivhaus Is About Comfort, Not Just Energy Bills Mention Passivhaus and many people immediately think of exceptionally low energy bills, thick insulation and triple glazed windows. 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 […]
Section 1: Treat the House as One Design Project, Not Twenty Separate Windows When homeowners decide to replace every window in their house, it is natural to begin by looking at the individual windows themselves. One may have failed seals, another may be difficult to open, while others simply look tired or no longer meet […]
