What Is RAL Silicone Sealant?

RAL silicone sealant is a standard silicone sealant that has been colour matched to a specific shade in the RAL colour system, rather than being left in a generic white, clear or grey finish.

The RAL system is widely used across construction, architecture and manufacturing to specify exact colours, which makes it a natural fit for sealants used alongside colour-matched frames, cladding and panels. Instead of a sealant joint standing out against a coloured surface, a RAL matched sealant blends in for a clean, professional finish.

RAL sealant is commonly used for windows and doors, aluminium frames, cladding and panel systems, and general finishing work where colour consistency matters. Because it's matched to a recognised RAL code, it's straightforward to specify the same colour again on a future project.
