Key Performance Requirements for Flat Roof Fasteners

There is a range of requirements that a fastening element must meet for flat-roof applications. 

Tensile Strength and Pull-Out Resistance

In addition to the static function concerning tensile strength, the physical properties of the building also play a role, taking into account the minimisation of thermal bridges. 

Corrosion Resistance in Flat Roofing Environments

Also, greater state-of-the-art corrosion resistance is required. 

Ageing Resistance and Long-Term Roof Durability

If plastic fastener combinations are installed, the ageing resistance must be certified as well. 

Resistance to Imposed Loads and Insulation Compatibility

Depending on the insulating material used, attention should also be paid to the fastener combination concerning resistance to imposed loads. 

Installation Efficiency and Pre-Assembled Fastener Systems

Good plasticity with the same high-quality standard, if necessary, also mechanically or in the form of pre-stored fastener combinations, completes the list of requirements on mechanical flat roof fastening elements. In the next part of our flat roof guide, we will look at the several types of securing the position of roof waterproofing membranes.
