KnuckleHeads will prevent damage caused by ponding water, wind, ice, flying debris or seismic events and protect the integrity of the roofing system including roof-mounted structures and equipment.
They are engineered with a Universal Base. A range of head designs are available depending on the particular support application needed.
KnuckleHeads can be attached directly to the roof substrate either mechanically combined with GREEN LINK Adhesive/Sealant, or with GREEN LINK Adhesive/Sealant alone.
Where the protocols of the original single-ply membrane manufacturer and/or warranty provider must be met, a Halo Target Flashing can be applied. MB, EPDM, PVC, and TPO Halo Target Flashings are available from GREEN LINK. Flashings are heat welded and/or adhered to the KnuckleHead base and to the roofing membrane.
In some applications, GREEN LINK Adhesive/Sealant by itself is sufficient to create a strong bond with more than 250 psi shear strength to ensure KnuckleHead integrity under high wind conditions or seismic events. Pipe straps are available to provide additional security.
