Thrakon PU Gun Foam

About this product

Thrakon PU Gun Foam is a 750ml, one-component, self-expanding polyurethane foam for professional mounting, filling and sealing. It cures by reacting with air humidity and bonds to almost every building material you will meet on site.

Its main use is filling holes and gaps in thermal insulation boards, where a good fill matters for the airtightness of the job. That makes it a natural fit for external thermal insulation (ETICS) work, though it does the same job on general construction. High filling capacity and good sealing mean fewer passes to close a gap.

The formulation also gives waterproofing and mould protection, so the filled joint stays dry and clean over time. It is gun-grade, so it needs a foam gun for application, for better control and less waste.
