* Length of Dekfast will vary depending on the total thickness of the rigid insulation and metal deck.
The following information should be used to determine system components needed once insulation
size has been selected. Refer to Fastener Selection Guide on pages 11, 12 for proper fasteners required
for selected componenets.
SEAM-LOC 24 PANEL CLIPS
- The floating clip allows the roof surface (panels) to move independently of the roof substructure to
allow for thermal expansion and contraction. These clips are designed with a vertical tab that slides
along the base section of the clip. Clips are placed along the male leg of each panel prior to installing
adjacent panels. Design wind uplift requirements must be considered for proper clip spacing
- The fixed clip does not allow the roof surface (panels) to move independently of the roof substructure
allowing for thermal expansion and contraction. These clips are only recommended for buildings
designed with panel lengths less than 30'-0".
