How To Specify Architectural Glazing

When specifying architectural glazing systems, architects and developers must consider numerous factors. Ensuring compliance with building codes and regulations, particularly those related to energy efficiency and safety, is paramount. Functional requirements such as sunlight exposure, heat management, noise reduction, privacy, and security must also be addressed.

Additionally, climate-related factors like solar exposure, wind loads, and condensation control should be taken into account, alongside prioritising low U-values and high solar heat gain coefficients to maximise energy efficiency.

Moreover, aesthetics, safety, and noise insulation are crucial considerations. Architects must also factor in maintenance, longevity, cost, and collaboration with suppliers. By carefully making all these considerations, designers and homeowners can make informed decisions that meet the project’s requirements.

Framed Architectural Glazing and Glass Specifications

When specifying architectural glazing systems, various design choices come into play. Initially, the frame material is a key decision, with options ranging from aluminium to timber and even steel, depending on the project’s needs and desired aesthetics.

Glass size is another critical factor in the specification process. While glazing can typically be customised to fit nearly any size requirement, larger panels may necessitate additional support to withstand higher than average wind loads. Depending on the climate, double or triple glazing may be chosen to optimise thermal performance.

Additionally, the colour of the glass is a significant consideration, as it is influenced by the size of the glazing and its thickness. Low iron glass, lacking the green tint of clear glass, may be preferred for its enhanced clarity and transparency, particularly when viewing through the glass is a priority.

Performance Specifications

While aesthetics play a significant role in specifying glazing systems, the primary considerations revolve around solar heat gain coefficients and low U-values.

Solar heat gain coefficient (SHGC) and U-values are closely intertwined. SHGC evaluates how effectively the glazing blocks heat from the sun, aiming for minimal SHGC to minimise heat transfer from outside to inside, ensuring occupants’ comfort. A favourable SHGC rating also aids in retaining cold air indoors, enhancing cost efficiency for air-conditioned spaces. This, in turn, assigns the glazing a U-value, which measures its thermal performance.

Various factors can impact glazing performance, including whether the glass is double or triple glazed. Depending on the building’s requirements, architects and developers will specify the necessary type of glazing to meet thermal performance needs.

As specification can be an intricate and longwinded process, the Belgravia team caters its expertise on a project-by-project basis, ensuring your chosen glazing systems are optimised for your specific performance and aesthetic requirements.
