If you’re involved in specifying rainscreen systems, you'll know how essential it is to ensure that the spacing and fixing of the bar and bracket support system is accurate.
There are two main factors to consider – the weight of the rainscreen itself, and the wind and how this may affect the fixing of the rainscreen.
The weight of the rainscreen is important as this will determine the type and number of fasteners required to support the material. Wind can put considerable force on a structure and could potentially rip the rainscreen off the building if not fixed correctly.
Additionally, location, height, the size and shape of the building, whether the openings are large or small, the type of surrounding landscape can also have a big impact on how the rainscreen should be fixed. Leaving a facade fixing pattern to chance is a big risk, and over-specifying for the sake of safety can significantly increase the cost to the contractor or client.
Fortunately, there are UK-specific European regulations which detail exactly how to arrive at a safe fixing pattern but are technically very complex.
If you are interested in using Fixfast’s façade bar and bracket system, the technical team at Fixfast can carry out facade calculations. These give the information you need to give an a structurally safe & sound fixing pattern, as well as recommending the correct type of fastener for your project.
We will send you a full report via email.
The calculation report is clear and comprehensive showing exactly what you need to know to fix a façade safely and cost effectively.
All calculations are in accordance with European Standards (EN 1991-1-1:2002. Eurocode 1: Actions on structures — Part 1-1: General actions; EN 1991-1-4:2005 + A1:2010.
