As a leading UK manufacturer of cutting-edge Flatglass Rooflights, the Roofglaze Technical Team have a full and comprehensive understanding of non-fragility, the legal requirements surrounding specifying non-fragile rooflights and the issues that should be considered when designing rooflights into buildings.
In the realm of roof and building design, the terms “non-fragile” and “walk-on” are often used interchangeably, but they represent distinct concepts. It is imperative for designers and specifiers to recognize these differences to avoid over-specifying or, more critically, under-specifying these specialized products.
Roofglaze’s Technical Team is poised to guide professionals through this nuanced landscape, ensuring that rooflights are chosen and specified with precision, aligning seamlessly with the project’s needs, safety requirements, and design aspirations. Their expertise serves as an invaluable resource in the pursuit of excellence in construction and architectural design.
When designing a roof or building, the terms “non-fragile” and “walk-on” are often used interchangeably when, in reality, they are quite different and the designer / specifier should ensure that they understand the difference so as not to over-specify, or more crucially under-specify, these types of products.
A non-fragile rooflight is not designed to be walked on. It is designed to save lives by preventing people or objects accidentally falling through it when accessing roof areas that are not designed for regular foot traffic.
On the other hand, a walk-on rooflight is engineered with structural requirements in mind and is intended to bear the weight of deliberate foot traffic. These rooflights are specified in areas where regular access by individuals is part of the design, such as rooftop terraces or observation decks. Their robust construction and load-bearing capabilities make them suitable for these purposes.
Understanding these distinctions is essential for architects, designers, and specifiers to ensure the appropriate selection and placement of rooflights within a building’s design, prioritizing both safety and functionality.
A walk-on rooflight is designed to take structural requirements into consideration and should be specified where deliberate foot traffic will occur.
