Triple Glazed Flat Roof Windows

No matter what your project, we will have a flat roof window for you — but with so many styles and sizes to choose from, it can often be difficult to decide between double and triple glazing. While both are fantastic for drawing in additional natural light, triple glazed windows are perfect for those looking to create an extra layer of defence against the elements.

While single glazing features one pane of glass, triple glazing boasts three. This sealed construction creates a protective barrier against the exterior environment. As well as allowing you to create a stylish and light-filled interior space, triple glazed flat roof windows have an array of other benefits…


Triple glazed flat roof windows like Fakro DSF-D U6 Triple Glazed Smoke Ventilation Flat-Glass Flat Roof Window offer fantastic insulation levels, so you will be able to retain your interior warmth, no matter what the weather is doing outside. The ultimate choice for homeowners in particularly exposed locations, triple glazed flat roof windows will help you fight against even the harshest winter conditions.

Triple glazing is also extremely thermally efficient, which allows for long-term energy savings on bills. This makes them perfect for those looking to achieve the lowest u-value possible or reduce their carbon output. Plus, due to the thickness of the glass, triple glazing can also stop exterior noise in its tracks, which can be very beneficial for homes positioned near busy roads, flight paths or train lines.

With three panes of glass and argon gas, triple glazed flat roof windows provide better insulation than single or double glazed options. The multiple layers prevent heat loss and noise pollution while letting in plentiful natural light. Triple glazing offers homeowners the best of both worlds – beautiful, pure glass to appreciate views and light, with the highest levels of energy efficiency.
