<\/div><\/div>\n\n\n\n

You know those glass buildings that look like they are made entirely of windows? The ones where you can see people working on the fifteenth floor from the street? That is curtain walling. It is everywhere now, but most people walk past it every day without knowing what it is called or how it works.
<\/h2>\n\n\n\n
<\/div><\/div>\n\n\n\n

I spent some time looking into this because honestly, I was curious about how those buildings stay up. Turns out the glass is not holding anything up at all. The building has a concrete or steel frame inside, and the glass front just hangs off it like a jacket. That is why they call it a curtain wall.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n
Curtainwalling in Modern Architectural Design<\/h5>\n\n\n\n
<\/div><\/div>\n\n\n\n

Here is how buildings used to work. The walls did everything. They held up the roof, they held up the floors, they kept the weather out. If you wanted a window, you had to leave a hole in the wall, and the hole could only be so big because the wall needed to stay strong.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

Then someone figured out that if you build a frame first, the walls do not need to carry anything. They can just be a skin. This changed everything. Suddenly architects could make windows as big as they wanted. They could wrap whole buildings in glass if they felt like it. And plenty of them did.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

Curtainwalling is just the name for that skin. It is a frame, usually aluminium, that holds glass or panels. It gets bolted onto the edge of the floors, hangs down, and keeps the weather out. Simple idea, but it takes a lot of engineering to get right.
<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

The system has to handle rain, wind, heat, cold, and the fact that buildings move around a bit in the wind. All while looking neat and tidy from the outside. That is harder than it sounds.
<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

Koemmerling Aluminium Systems knows this stuff better than most. The company spent over a hundred years making windows and doors before getting into aluminium facades. That matters because making windows teaches you about seals, about what lasts, about how things fit together. Those lessons carry over into curtain walling.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n
What does curtainwalling mean in contemporary construction?<\/h5>\n\n\n\n
<\/div><\/div>\n\n\n\n

If you are on a building site and someone says curtain wall, they mean a metal grid. Vertical bits called mullions, horizontal bits called transoms. The grid holds glass or solid panels. That is it really.
<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

But the grid has to do a lot:<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n
    \n
  • Deal with movement: Buildings sway. They also expand when hot and shrink when cold. The glass fixed to the front has to move with all that without cracking. Engineers spend a lot of time figuring this out.<\/li>\n\n\n\n
  • Stop heat leaking: Metal conducts heat like crazy. If you just bolted aluminium frames straight onto a building, heat would pour out in winter and pour in during summer. Modern systems put plastic strips inside the frames to break that heat flow. They call these thermal breaks.<\/li>\n\n\n\n
  • Keep water out: Rain does not just fall straight down. Wind drives it sideways, sometimes upwards. The joints between glass and frame have to stop water getting in, year after year, without failing.<\/li>\n<\/ul>\n\n\n\n
    <\/div><\/div>\n\n\n\n

    Choosing a curtain wall is a big decision. Get it wrong and the building leaks, or costs a fortune to heat and cool, or looks rubbish within a few years. That is why developers tend to go with suppliers who have been around a while.<\/p>\n\n\n\n

    <\/div><\/div>\n\n\n\n
    How aluminium curtain walling shapes building exteriors<\/h5>\n\n\n\n
    <\/div><\/div>\n\n\n\n

    Aluminium is the material that makes all this possible. Not steel, not wood, not plastic. Aluminium. Aluminium curtain walling works because the metal has properties that suit tall buildings perfectly.<\/p>\n\n\n\n

    <\/div><\/div>\n\n\n\n
      \n
    • It is light. Steel strong enough for a frame would weigh too much hanging off the edge of a building. Aluminium gives you strength without the weight.<\/li>\n\n\n\n
    • It does not rust. Steel rusts. Aluminium forms a protective layer that stops corrosion, which matters when rain hits the facade constantly.<\/li>\n\n\n\n
    • You can shape it. Makers push aluminium through dies to create complicated profiles, with channels for gaskets, thermal breaks, and fixings that all fit together precisely.<\/li>\n\n\n\n
    • It takes colour well. Powder coating or anodizing means the frames can be almost any colour and stay that way for decades without fading or peeling.
      <\/li>\n<\/ul>\n\n\n\n
      <\/div><\/div>\n\n\n\n

      Next time you walk past a glass building, look at the corners. The lines are sharp. The joints are clean. That precision comes from the material and from the people who design the profiles.
      <\/p>\n\n\n\n

      <\/div><\/div>\n\n\n\n

      Koemmerling focuses on these details. The engineers have spent years developing profiles that work well and look right. Other companies sometimes copy those designs, which tells you something about the quality.<\/p>\n\n\n\n

      <\/div><\/div>\n\n\n\n
      The visual appeal of modern curtain walling<\/h5>\n\n\n\n
      <\/div><\/div>\n\n\n\n

      Looks matter with modern curtain walling. Not just because architects want pretty pictures for their websites, but because the people who own and use the building have to look at it every day. A good facade gives a building presence. It catches light differently through the day. It reflects the sky or the buildings opposite. It makes the place look like someone thought about it.
      <\/p>\n\n\n\n

      <\/div><\/div>\n\n\n\n

      There are different ways to put curtain walls together, and each gives a different look:<\/p>\n\n\n\n

      <\/div><\/div>\n\n\n\n
        \n
      1. Unitized systems: Big panels built in a factory, trucked to site, lifted by crane, and bolted together. Fast installation, consistent quality, and the joints between panels become part of the design. You see these on big commercial towers mostly.<\/li>\n\n\n\n
      2. Stick systems: Frames assembled piece by piece on scaffolding. More labour, more flexibility during construction, and often used where access is tricky or the design changes floor by floor.<\/li>\n\n\n\n
      3. Structural silicone glazing: Glass bonded to the frame with silicone, so from outside you see no metal caps or covers. Just glass and the reflections on it. This is the seamless look you see on high end projects.
        <\/li>\n<\/ol>\n\n\n\n
        <\/div><\/div>\n\n\n\n

        Each approach suits different budgets and design goals. But all of them rely on getting the details right early, because fixing mistakes in a curtain wall after installation is expensive and complicated.<\/p>\n\n\n\n

        <\/div><\/div>\n\n\n\n
        Where curtainwalling is commonly used today<\/h5>\n\n\n\n
        <\/div><\/div>\n\n\n\n

        Curtainwalling turns up in more places than people realise. Yes, office towers. But also:<\/p>\n\n\n\n

        <\/div><\/div>\n\n\n\n
          \n
        • Airports: Those big, light spaces where you wait for flights, they need glass to feel open rather than cramped. Curtain walls make that possible across large areas.<\/li>\n\n\n\n
        • Train stations and bus interchanges: Places where natural light helps people find their way and feel safe.<\/li>\n\n\n\n
        • Museums and galleries: Modern cultural buildings often want transparency to invite people in. Glass walls say “this is for everyone” in a way that stone cannot.<\/li>\n\n\n\n
        • Expensive apartments: Developers sell views. Floor to ceiling glass makes the most of those views and the price they can charge.<\/li>\n\n\n\n
        • Mixed use developments: Shops with offices above, all wrapped in the same facade system, tying the building together visually.
          <\/li>\n<\/ul>\n\n\n\n
          <\/div><\/div>\n\n\n\n

          The system adapts to each use. Airports need huge spans. Apartments need thermal performance so balconies are usable. Offices need solar control so staff are not roasted by afternoon sun. Good suppliers understand these differences and design accordingly.
          <\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n

          Koemmerling has worked across all these building types. The systems go into new builds and also into refurbishments, replacing old facades on existing buildings to update their look and performance.<\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n
          The role of curtainwalling in light-filled structures<\/h5>\n\n\n\n
          <\/div><\/div>\n\n\n\n

          Here is the thing about curtainwalling. It lets light in. Not through small holes in a wall, but across whole floors. Offices built with curtain walls feel different to work in. Deeper spaces get daylight. Corners are bright rather than gloomy. People sit near glass rather than in the middle of a dark floor.<\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n

          Research backs up what people already know: daylight makes workspaces better. People concentrate more, feel less tired, call in sick less often. Hospitals with natural light in patient rooms see faster recovery times. Schools with good daylight have students who perform better. These are not minor effects.
          <\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n

          In homes, the difference is even clearer. A living room with a full height glass wall feels larger than the same space with standard windows. The line between inside and outside blurs. City views become part of the apartment. Private gardens feel connected to the rooms they serve.
          <\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n

          This focus on light is not a passing trend. Building regulations in many countries now require minimum daylight levels in occupied spaces. Curtain walls help meet those requirements while giving architects freedom to design interesting shapes.
          <\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n

          Koemmerling’s systems are designed with this in mind. The frames are slim where they need to be slim, letting glass dominate the facade. The engineering focuses on thermal performance so large glass areas do not turn buildings into greenhouses or fridges.<\/p>\n\n\n\n

          Frequently Asked Questions about Curtainwalling<\/h5>\n\n\n\n
          <\/div><\/div>\n\n\n\n
          What is the difference between a curtain wall and a standard window wall?<\/h6>\n\n\n\n

          A window wall sits between the floor slabs. It rests on the slab below and stops at the slab above. A curtain wall runs past those slabs, fixed to them but not resting on them. This means curtain walls can run floor after floor without a break. That is why tall buildings look seamless from outside. Window walls always have a visible break at each floor level.<\/p>\n\n\n\n

          <\/div><\/div>\n\n\n\n
          How does curtainwalling help make a building more energy efficient?<\/h6>\n\n\n\n

          Modern curtain walls use thermal breaks in the frames. These are strips of plastic that separate the inside metal from the outside metal. Heat cannot travel easily through plastic, so the frame stays warmer inside. The glass itself matters too. Double or triple glazing with special coatings lets light through but holds heat in, or reflects heat out depending on the climate. The whole system is designed to be airtight, stopping drafts that waste energy.<\/p>\n\n\n\n

          Why do architects and builders trust Koemmerling for facade systems?<\/h6>\n\n\n\n

          Koemmerling has been making windows and doors for over a hundred years. That experience shows in the details. The profiles are well designed. The thermal breaks work. The gaskets seal properly. The finishes last. Builders trust the systems because they install without fights on site. Architects specify them because the profiles are slim and the performance data stacks up. The company works in over one hundred countries, so the products have to perform in different climates and meet different regulations. That breadth of experience matters when a project is complicated.

          <\/div><\/div>\n\n\n\n

          Whether it is a new office tower downtown or an old house getting new windows, Koemmerling brings the same approach: get the details right, use good materials, and make sure it lasts. That is why the name keeps coming up when people talk about quality aluminium systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
