Frequently Asked Questions
What work belongs in Curtain Wall, Façade & Movement Joints?
This stage covers flexible sealing of curtain-wall modules, façade interfaces, window perimeters, aluminium cladding, and movement joints. The assigned Products include Bostik Seal-N-Flex FC, P390, P590, Dowsil 791, SA Contractors, Sikaflex Construction AP, and RLA MS Pro. Several are general building Products, so final membership requires trades-owner confirmation.
Why are polyurethane and MS polymer Products considered?
The evidence for these sealants names window perimeters, curtain walls, fenestration, aluminium, or metal cladding. Those are direct work-context signals for façade and movement sealing, but chemistry alone is not the reason for inclusion. Each Product remains subject to its own substrate, movement, weathering, and cure limits.
Is every façade sealant a Glazing Product?
No. A façade or movement-joint description can support adjacent construction work without proving a Glazing trade role. Products such as P390, P590, Sikaflex Construction AP, and RLA MS Pro need the trades owner to confirm whether glazing customers use them or whether they belong only in broader construction journeys.
Does SA Sealproof have direct glazing evidence?
Yes. SA Sealproof is described for curtain-wall modules and glass-to-metal framing systems, including movement in butt and lap-shear joints. Its local snapshot therefore supports this stage more directly than general construction sealants. The live Product is Archived, so it is excluded from the published stage until a current successor or restore decision is made.
Should Sikasil Pool be in this stage?
Sikasil Pool is documented for flexible joints involving glass, aluminium, and immersed or wet-area conditions. That creates a plausible overlap with Glazing, but pool work is better served by Waterproofing. It is excluded from this stage; the Waterproofing journey owns it.
