The character of Sigilla.
A multi-purpose architectural sealant range used for joint, gap and edge sealing across many substrates. Built for finished-home projects and window-and-door packages at home, and for engineering close-out and maintenance channels abroad.
Three chemistries, one supplier
MS / PU / neutral silicone: pick the right chemistry per substrate while keeping a single supplier and PO line.
±25% joint movement
High movement capability handles thermal expansion and structural micro-movement without joint failure.
Wide service temperature
Performs from −20 °C to +80 °C: suited to cold-region winters and Middle-East summer envelopes alike.
Fast skin-over
Touch-dry in 10–30 min keeps sites moving: installer can mask, tool and clean in one pass.
