Details

Reliable Automatic Welder

UNIROOF ST is an efficient and reliable automatic welder for thermoplastic membranes on the roof. It’s ideal for parapets, edges, medium sized roofs, residential roof projects and more. UNIROOF ST is compact, easy to operate, and easy to transport thanks to its carrying handle and light weight of only 38.6 lbs. The pressure roller’s high contact pressure and low-maintenance, direct drive guarantee optimal welding results.
UNIROOF ST easily welds edges up to 4″, as well as on or at the parapet. This significantly reduces the need to hand weld specific areas on the roof. The brushless motor in the 3,450W hot air blower promised to provide precise welding and a long life span of the tool.
