Round ducting VSP

Round ducting VSP for ventilation systems

Round ducting VSP is the backbone of supply and exhaust ventilation systems in residential, commercial and industrial buildings. The round cross-section ensures stable aerodynamics, low airflow resistance and highly airtight connections, while the spiral seam gives the duct rigidity and strength. The range includes both the ducts themselves and a full set of fittings — bends, reducers, tees and connectors — allowing systems of any configuration to be assembled from components by a single manufacturer. VSP's own production guarantees consistent quality and precise geometry, with delivery to projects in Estonia, Latvia and Lithuania.
