What is BS EN 410 - Glass in building about?
BS EN 410 is a European Standard. BS EN 410 discusses scope, definitions, symbols, light transmittance and much more in detail to ensure maximum efficiency. BS EN 410 also contains relevant annexes.
BS EN 410 has been prepared by Technical Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by NBN.
BS EN 410 applies both to conventional glazing and to absorbing or reflecting solar-control glazing, used as vertical or horizontal glazed apertures. The appropriate formulae for single, double, and triple glazing are given.
Note 1: BS EN 410 applies to all transparent materials except those that show significant transmission in the wavelength region of 5 μm to 50 μm of ambient temperature radiation, such as certain plastic materials.
Note 2: Materials with light-scattering properties for incident radiation are dealt with as conventional transparent materials subject to certain conditions (see 5.2).
Note 3: Angular light and solar properties of glass in the building are excluded from this standard. However, research work in this area is summarised in Bibliography [1], [2] and [3].
Note 4: While BS EN 410 presents the formulae for the exact calculations of the spectral characteristics of glazing, it does not consider the uncertainty of the measurements necessary to determine the spectral parameters that are used in the calculations. It should be noted that, for simple glazing systems where few measurements are required, the uncertainty of the results will be satisfactory if correct measurements procedures have been followed. When the glazing systems become complex and a large number of measurements are required to determine the spectral parameters, the uncertainty is cumulative with the number of measurements and should be considered in the final results.
Note 5: In Annex B, the procedure for the calculation of spectral characteristics of laminated glass makes a specific reference to coated glass. The same procedure can be adopted for filmed glass (e.g. adhesive-backed polymeric film applied to glass).

Why should you use BS EN 410 - Glass in building?
Determining the luminous and solar characteristics of glazing glass in buildings is becoming more important than ever. Using BS EN 410 can ensure precision and high performance.
BS EN 410 specifies methods of determining the luminous and solar characteristics of glazing in buildings. This characteristic can serve as a basis for lighting, heating and cooling calculations of rooms and permit comparison between different types of glazing. These characteristics also ensure that the temperature of the rooms is maintained. Energy efficiency is taken into consideration too.
Standardizing glazed glass is crucial as the majority of households prefer high-performance glazed glass considering its numerous benefits like temperature maintenance, durability and saving energy. Compliance with BS EN 410 ensures maximum efficiency and durability.
What’s changed since the last update?
BS EN 410:2011 supersedes BS EN 410:1998 which is withdrawn. BS EN 410:2011 includes some changes with respect to BS EN 410:1998. These include:
- A procedure is provided for the calculation of the spectral properties of laminated glass
- A formula is introduced for determining the total shading coefficient
- Guidance is also given on how to determine the spectral characteristics of screen-printed glass
- The external and internal heat transfer coefficients have been amended slightly to reflect changes to EN 673.
- Table 3 and Table 6 have been updated to make them more practical
