Pitched Roof Terminals

Stack Terminals- Insulated

UB46, UB47, UB48 & UB49.

Proper insulation of ductwork in ventilation, heating, or cooling systems is essential to minimise heat loss and prevent condensation. Ubbink offers a comprehensive range of insulated terminals designed for easy installation and maintenance.

Key Features:

• Compatible with tiles and slates, suitable for roof pitches from 25° to 45°.
• Fully insulated, including the cowl, to prevent condensation in varying temperature conditions.  

Product Specifications:
Our insulated terminals are available in the following models:

• UB46: 125mm diameter | Free vent area: 12,250mm²
• UB47: 150mm diameter | Free vent area: 17,750mm²
• UB48: 180mm diameter | Free vent area: 19,100mm²
• UB49: 160mm diameter | Free vent area: 18,750mm²

All models maintain a pressure airflow resistance of <1.0 Pascal at 225m³/h, ensuring high efficiency and performance.

Stack Terminals- Twin walled

UB34 & UB35 

The Multivent Service Terminals are designed for systems requiring low resistance, making them ideal for mechanical and natural (passive) ventilation installations.

Key Features:

• Twin-walled pipework above the roofline with an integrated condensation drain.
• Compatible with tiled and slated pitched roofs (25–45°).
• Universal flashing included for both tiles and slates.
• Special versions for lower or higher pitches available on request.

Specifications:

• UB34: 125mm diameter | Free vent area: 12,250mm²
• UB35: 160mm diameter | Free vent area: 18,750mm²

Both models maintain a pressure airflow resistance of <1.0 Pascal at 225m³/h, ensuring excellent efficiency.

In-line Terminal

UB37

The Ubbink Plain Tile Terminal (UB37) is an in-line pitched roof terminal designed for use with small plain, non-interlocking tiles. It is ideal for terminating 110mm diameter mechanical extract systems and soil & vent systems where external pressure testing is not required.

Key Features:

• Aesthetic design matches the UB8 roof ventilating tile.
• Free vent area: 6,250mm².
• Pressure/airflow resistance: 11Pa at 100m³/h.

The UB37 provides an efficient, visually integrated solution for ventilation needs.

In-line Slate Terminal

UB39

The Ubbink Vepac Terminal (UB39) is an in-line service terminal designed for slated roofs with pitches of 25–55°. It is ideal for terminating 110mm diameter mechanical extract systems and soil & vent systems where external pressure testing is not required.

Key Features:

• Matches the UB11 roof ventilating slate for a seamless aesthetic.
• Adapter must be fitted before roof installation.
• Not suitable as a pitched roof void vent due to the absence of an insect grille.

Specifications:

• Free vent area: 7,800mm².
• Pressure/airflow resistance: 19.0 Pascals at 100m³/h.

The UB39 combines functionality with a discreet design for efficient ventilation.

Universal Hooded Terminals

UB41

The UB41 is a Universal Service Terminal designed for use with most tiled and slated pitched roofs, eliminating the need to match specific tile or slate designs.

Key Features:

• Versatile Design: Suitable for ducting connections from 100mm to 160mm diameter with a stepped adaptor.
• Easy Installation: Adaptor can be trimmed to the required diameter and secured with solvent weld or PVC glue.
• Flexible Flashing: Includes a 500mm x 500mm Ubiflex flashing skirt, fitting seamlessly into most tiles and slates.
• Multi-Purpose: Can also terminate soil and vent pipes where external pressure testing is not required.

The UB41’s streamlined hood and circular upstand provide a sleek and efficient solution for a wide range of ventilation needs.
