To understand how to correctly fasten your Flat roof, we recommend a wind load calculation for each roof that needs to be mechanically fastened. This calculation results in fastener advice along with an installation plan with which you can complete your project as efficiently as possible.

By calculating the wind load, our team of experts take into account the different membrane widths and the distance between fasteners, to provide you with the best solution.  

On the strength of our close relationship with roofing membrane and insulation suppliers worldwide, over the years we have generated a vast volume of standard calculation values, enabling us to provide you with the most optimal installation plan.
