For these applications, 125mm creates excessive resistance that degrades extraction performance and increases fan noise, while rectangular flat-channel ducting — though more space-efficient — has worse aerodynamic properties than equivalent-area round duct and is harder to clean. Where space allows, 150mm round PVC is the preferred specification for kitchen and range hood extraction runs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIt is also widely used for MEV (mechanical extract ventilation) central spigot connections and for the main extract branches on residential ventilation systems where the air flow rate requires the larger bore.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat this is not designed for\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePVC round ducting in this range has no thermal insulation. Runs through cold loft voids, undercroft spaces, or unheated areas will lose heat and are susceptible to condensation on the duct exterior. For those applications — including MVHR trunk runs and heat pump water heater connections — the Verplas Self-Seal Thermal range in 160mm is the correct product. Note also that some older MVHR units and heat pump water heaters specify a 150mm spigot; the Verplas 160mm to 150mm thermal adaptor bridges that connection without reverting to uninsulated PVC for the main run.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSustainability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eVerplas manufactures all PVC duct lengths from recycled windows and door frames, diverting material that would otherwise go to landfill.
