2. Window insulation - Wikipedia

   en.wikipedia.org/wiki/Window_insulation

   The proportion of glass fibre in the profiles is 25%. The material used for this insulating bar stands out for its low thermal conductivity value (0.30 W/m2K) and its good mechanical properties even at higher temperatures. A non-thermally-separated frame from an aluminum window has a thermal transmission coefficient of 6.8 W/m2K. If the system ...

3. Window covering - Wikipedia

   en.wikipedia.org/wiki/Window_covering

   Window coverings comprise materials used to cover a window to manage sunlight, privacy, additional weatherproofing or for purely decorative purposes. Window coverings are typically used on the interior side of windows, but exterior solutions are also available. Window coverings may be used to manage overheating and glare issues due to sunlight.

4. Curtain wall (architecture) - Wikipedia

   en.wikipedia.org/wiki/Curtain_wall_(architecture)

   Designed by the architect Peter Ellis and built in 1864, it is the world's first building to feature a metal-framed glass curtain wall. 16 Cook Street, Liverpool, 1866. Extensive use is made of floor-to-ceiling glass, enabling light to penetrate deeper into the building, thus maximizing floor space. Glass curtain wall of Bauhaus Dessau, 1926

5. Window insulation film - Wikipedia

   en.wikipedia.org/wiki/Window_insulation_film

   A film is attached to the window frame to trap a pocket of air between the glass and the film, creating a double-glazed system with an insulating gap of still air. Thermal conductivity of still air is 0.024 W/(m.K) and much lower than that of glass (0.96 W/(m.K)). [1]

6. Rainscreen - Wikipedia

   en.wikipedia.org/wiki/Rainscreen

   Rainscreen cladding is a kind of double-wall construction that utilizes a surface to help keep the rain out, as well as an inner layer to offer thermal insulation, prevent excessive air leakage and carry wind loading. The surface breathes just like a skin as the inner layer reduces energy losses. [10]

7. Thermal transmittance - Wikipedia

   en.wikipedia.org/wiki/Thermal_transmittance

   The frame and double sealing of the window system are the actual weak points in the window insulation. Typical thermal transmittance values for common building structures are as follows: [citation needed] Single glazing: 5.7 W/(m 2 ⋅K) Single glazed windows, allowing for frames: 4.5 W/(m 2 ⋅K) Double glazed windows, allowing for frames: 3.3 ...
