Significant and Uninterrupted Energy Saving.
CUSMART® flexible tubes with external industrial insulation are suitable for all heating and hot water supply plumbing networks inside and outside buildings. The insulation is a cross-linked polyethylene (PE-X) foam structured in closed type microcells. Energy saving is a result of the spectacular reduction of temperature loss to over 50% compared to similar networks without insulation.
The CUSMART® all-inclusive flexible copper tube system includes a full range of CUSMART FITTINGS (press and compression fittings), as well as tools, ensuring reliable results in every application.
