Manthorpe GTV AD Roof Tile Vent Adaptor - 110mm Pipe Outlet

Manthorpe GTV AD Roof Tile Vent Adaptor - 110mm Pipe Outlet is a roof vent adaptor designed to connect compatible roof tile vents to extractor fans, mechanical ventilation or soil pipework, helping improve airflow and prevent moisture build-up from poorly routed ventilation.

It clips or fits to the underside/spigot of the compatible roof vent and sits internally at loft level, creating the transition from the external roof vent to the duct or flexipipe.

Best for

• Connecting roof vents to extractor fans, mechanical ventilation or soil pipes where specified
• Loft-level ducting work behind a roof-level tile/slate vent
• Ensuring moist air is routed outside rather than into the roof void

Key features

• Creates a ducted extraction route through the roof covering
• Helps prevent warm moist extractor air being released into the loft void
• Improves airflow from fans when paired with correctly sized ducting
• No tile cutting or lead flashing required where the compatible vent system supports clip-fit installation

Compatible with / used with

• Used with compatible roof tile vents only; check the exact Manthorpe, Klober or Timloc vent family before ordering
• Used with flexipipe or ducting for bathroom/kitchen extractor fans
• Can be used for soil ventilation where the vent/adaptor combination allows it
• Internal/loft-level accessory; the external roof vent is sold separately unless stated as a kit

Ventilation performance

• The adaptor itself does not create roof-space ventilation; performance depends on the compatible vent tile/slate vent and connected ducting.

Things to consider before buying

• Check the exact vent family and pipe diameter before buying
• Confirm whether the product is an adaptor only, flexipipe only or a combined kit
• For powered extraction, keep duct runs as short and smooth as practical and follow fan manufacturer guidance
• This accessory does not replace the need for the correct external roof tile/slate vent
