Why Rooflight Overheating Catches So Many People Out

hf 20260813 100206 469b12af 4919 442c 88ac ba8b62109b3c

The Problem Usually Starts With a Good Idea Rooflight overheating rarely begins with an obviously unreasonable design decision. More often, it begins with something entirely desirable: a brighter interior, a stronger connection with the sky and more daylight reaching parts of a home that conventional windows cannot easily serve. Consider a typical contemporary extension. Large […]

Flat Rooflights: Drainage, Falls and Long-Term Reliability

hf 20260813 100148 4b8d2222 30b5 4eb0 81d1 9c4691a29990

A “Flat” Rooflight Still Has to Manage Water The word flat can create a misleading impression when discussing rooflights. Architecturally, a flat rooflight may appear as a simple sheet of glass sitting almost effortlessly within the roof. Rainwater, however, still needs somewhere to go. The visual simplicity of the finished glazing does not remove the […]

What Rooflights Do to a Room That Windows Simply Can’t

Daylight From Above Behaves Differently Daylight entering through a roof does not behave in quite the same way as daylight entering through a wall. A conventional window creates an outward relationship, connecting the interior with a garden, street or landscape beyond. Its view is predominantly towards the horizon. A rooflight turns that relationship upwards, introducing […]

Rooflights vs Roof Lanterns: How to Choose Between Them

hf 20260813 093725 a7165ac4 a70f 4843 97a1 98ad236d5c52

Rooflights and Roof Lanterns Create Different Kinds of Space Rooflights and roof lanterns are often discussed as alternative ways of achieving the same objective: bringing more daylight into a room from above. Yet their architectural effect can be markedly different. The distinction is not simply one of appearance on the roof. Each changes the relationship […]

Why Sightline Figures in Glazing Brochures Are Rarely Comparable

hf 20260709 093052 5d8cec9a c062 4e13 852a 074a1841b220

The Problem With Comparing One Number Against Another Sightline figures are appealing because they appear to make comparison straightforward. Place two glazing brochures side by side, find the published dimensions and the system with the smaller number seems to offer the more minimal result. A difference of only a few millimetres can begin to look […]

Minimal Frames and Maximum Panes: Where the Limits Sit

hf 20260806 192810 a59e7612 ab77 43e3 909e 74009b10694f

Why There Is No Single Maximum Glass Size The question of how large a single pane of glass can be appears to invite a simple answer: a maximum width, a maximum height, perhaps a maximum overall area. In architectural glazing, however, those dimensions rarely exist as universal limits. The realistic size of a pane emerges […]

The Trade-Offs Nobody Explains About Minimal Sliding Systems

hf 20260812 081927 99778070 9716 44fc a942 689dfc51fd38

Minimalism Removes Visual Complexity, Not Technical Complexity The appeal of a minimal sliding system lies partly in how little of the system appears to remain. Large panes of glass replace conventional areas of framing, vertical divisions become increasingly restrained, and tracks or perimeter frames may be integrated into the surrounding architecture. The completed elevation can […]

What Slim Glazing Frames Can Cost You in Thermal Performance

hf 20260804 101257 9d8f792a fca7 479a 960c 5779aec62fb4

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 […]

Why Two Glazing Systems With the Same Sightline Can Perform Differently

hf 20260806 192810 a59e7612 ab77 43e3 909e 74009b10694f

Why Sightline Is an Aesthetic Metric, Not a Performance Rating Sightline dimensions are useful because they describe something immediately visible. When two glazed panels meet, the width of the framing between them contributes directly to the character of the elevation, and it is understandable that architects and homeowners use this measurement when comparing minimal glazing […]

How Slim Can Glazing Sightlines Realistically Go in a UK Home?

Why There Is No Single Minimum Sightline At first glance, asking how slim a glazing sightline can be seems as though it should have a straightforward numerical answer. Contemporary glazing systems are often discussed in terms of increasingly narrow profiles, making it natural to compare one dimension with another. The difficulty is that a sightline […]
