“Top Joint”: the butyl extruder

The Marval butyl extruder “Top Joint” is used to apply butyl (first barrier) on the double glazing spacer profile. It seals profiles from 6 to 30 mm, simultaneously on both sides, with a high quality result.
The extrusion heads can be opened manually or, on request, completely automatically, and a simple adjustment is all it takes to seal even shaped frames.
