Wind load

About our Tests

This ‘test’ video is a tongue in cheek look at windloading using StoVentec as our guinea pig. Wind load is often the largest force applied to the façade of the building, either with a positive pressure or a negative suction load. It can vary dramatically due to location, building shape, size, proximity to other buildings or topographical features. In extreme circumstances this can lead to structural failure of key components, such as windows, facade cladding, roofs and sometimes even masonry.

The BBA has recently changed its interpretation of wind load calculations. The results are a significant increase in the Factor of Safety (FoS) now applied to mechanical rail systems. Unless it can be demonstrated otherwise, additional fixings will be required to comply with the changes. This affects all system providers. You’ll be glad to know that all mechanical system from Sto comply.

About the System

The StoVentec Facade system is a ventilated rainscreen cladding system, offering a host of advantages including:

• Unrestrictive designs – allows for tight curves and a variety of materials and textures
• StoVentec rainscreen permits the use of dark colours by minimising the build-up of heat
• Suitable for new build and refurbishment projects
• Can incorporate Sto insulation panels to exceed current U Value requirements
