Welcome to the SFS intec Tutorial. The following demonstration will talk you through the ideal way to install the SFS intec clamping fastener to secure the side lap of profiled sheets. This is key to achieving the air tightness requirements of Part L2, and meeting a building’s Energy Performance Certificate.
You will already have applied your Pink Strip sealant tape and positioned your top strip. Clamping fasteners are designed to clamp the side laps of profiled sheets on metal roofing and cladding panels. Designed with an integral 40 shore EPDM washer and threadless free-spin zone underneath the head, the fastener eliminates traditional problems such as over-driving and stripping out which can cause water ingress and air leakage.
Specifically for this demonstration we are using the SLP2 purpose-made side lap stitching fastener to secure 2 side end laps already sealed with SFS intec warranted Pink Strip sealant.
Put the fastener into the end of the drill nose and put into position over the joint. Insert the fastener into the lap and drive down until the fastener head is flush and spinning freely.
The free spin zone sections clamp both sheets tightly together, therefore compressing the butyl sealant, preventing air leakage and water ingress through the outer skin.
The design features of this fastener ensure a small pilot hole thread forms into both outer skins of the metal building.
Unlike traditional fasteners, no matter how much you continue to drill and spin the clamping fastener, you cannot over-drive it and strip it out.
Do not worry if the fastener appears loose once you have followed these steps. This means that the purpose-designed free spin zone under the head of the fastener has securely clamped the materials together.
