SST – Structural Spacer Tape
ARBOPROTECT Pro®
ARBOPROTECT Pro® SST is a specialised load-bearing PVC foam tape, designed to act as a spacing element between the insulated glass (IG) unit and frame during the assembly of structural glazing fabrications. SST forms an effective short-term bond between the frame and the IG unit, creating a gap of the correct dimensions for the structural silicone, which is used as the primary bond.

Unique properties of ARBOPROTECT Pro® SST
ARBOPROTECT PRO® SST eases the assembly of structural glazing elements by forming an effective short-term bond that holds the IG unit in correct position while the structural silicone is applied and cures. It is compatible with Ultraglaze Structural Silicone.

Main Applications
ARBOPROTECT Pro® SST are recommended for use as a spacing element in structurally glazed fabrications where the IG unit must be held in correct position during structural silicone application and cure.
Structural Glazing Assembly
Acts as a spacing element between the IG unit and frame, holding the correct gap for structural silicone during assembly.
IG Unit Positioning
Forms an effective short-term bond to hold the IG unit in the correct position while the structural silicone is applied.
Structural Silicone Preparation
Creates a gap of the correct dimensions for Ultraglaze Structural Silicone, which is used as the primary structural bond.
Glazed Curtain Wall & Façade
Used in structurally glazed curtain wall and façade fabrications where precise IG unit spacing is critical.
