2. ETFE - Wikipedia

   en.wikipedia.org/wiki/ETFE

   ETFE is effectively the high-strength version of the other three in this group. ETFE film is self-cleaning (due to its nonstick properties) and recyclable. [2] As a film for roofing it can be stretched and still be taut if some variation in size, such as that caused by thermal expansion, were to occur.

3. Low emissivity - Wikipedia

   en.wikipedia.org/wiki/Low_emissivity

   As it is an opaque material, the remaining 10 percent must be reflected. Conversely, a low-e material such as aluminum foil has a thermal emissivity/absorptance value of 0.03 and as an opaque material, the thermal reflectance value must be 1.0 - 0.03 =0.97, meaning it reflects 97 percent of radiant thermal energy. Low-emissivity building ...

4. List of refractive indices - Wikipedia

   en.wikipedia.org/wiki/List_of_refractive_indices

   Refraction at interface. Many materials have a well-characterized refractive index, but these indices often depend strongly upon the frequency of light, causing optical dispersion.

5. Vector Foiltec - Wikipedia

   en.wikipedia.org/wiki/Vector_Foiltec

   Vector Foiltec is a business using transparent plastic cushions filled with air as an architectural cladding technology. This solution can be better than glass panels in applications such as roofs over aggressive environments where chemicals would attack a metal window frame, or where the transparent panels have to accommodate deformation due to changing thermal conditions.

8. Refractive index and extinction coefficient of thin film ...

   en.wikipedia.org/wiki/Refractive_index_and...

   The challenge of characterizing thin films involves extracting t, n(λ) and k(λ) of the film from the measurement of R(λ) and/or T(λ). This can be achieved by combining the Forouhi–Bloomer dispersion equations for n ( λ ) and k ( λ ) with the Fresnel equations for the reflection and transmission of light at an interface [ 21 ] to obtain ...
