Flat Roof- Void Vent OFT2
Due to its stable resistance, the Flat Roof Void Vent works perfectly under all wind conditions. It has an integrated adhesive plate and the extra screw holes ensure that the duct remains firmly in place. Due to its design, the PP hood has a very large ventilation capacity. The roof duct is protected against rain and is suitable for new construction and renovation. The Flat Roof Vent is elegant on your roof, small in size, robust in design and delivers top performance.
Key features & benefits:
- Made of high-quality PP / Aluminium
- Applicable for all weather conditions
- High ventilation capacity
- No rain ingress
- Elegant design
- For new build and renovation purposes
Application:
- Void vent for 3 layer torch on felt /asphalt / GRP
- Black Cap & Aluminium flange only- No stack provided
Flat Roof Terminals- OFT1
The OFT Flat Roof Terminal is engineered to provide effective and efficient ventilation solutions for flat roof applications. Its design incorporates a large free vent area and low pressure (Pa) resistance, which significantly enhances airflow while reducing energy consumption.
Key features & benefits:
- Large Free Vent Area / Low Pa Resistance: Ensures optimal airflow with minimal resistance, enhancing the efficiency of your ventilation system.
- Accommodates Ducting up to 166mm: Designed for seamless termination through a flat roof to ducting with a diameter from 110mm to 166mm.
- Customisable Spigot Length: The spigot can be cut (below the roof) providing flexibility to meet specific ventilation needs.
- Compliance with Building Standards: Meets the necessary requirements for ventilation in flat roof constructions, ensuring adherence to building regulations.
Application:
- Residential Buildings: Ideal for a variety of home ventilation needs
- Bathroom Fans: Ensures effective ventilation for bathrooms
- Utility Fans: Suitable for utility room ventilation.
- For roof coverings: • Asphalt • Built up felt • EPDM • Bitumen • GRP roofs
Flat Roof Terminals - OFT4
The OFT 4 is designed to offer optimal ventilation for flat roofs, featuring a special low air resistance cowl with a pressure/airflow resistance of less than 1.0 Pascal at 225m³/h. Available in a variety of materials, it ensures efficient airflow with minimal resistance. The twin-walled pipework above the roofline includes an integral condensation drain, providing effective moisture management. The stack pipe comes with an integral collar and separate flashings to match the selected materials. Please note, the OFT 4 is not recommended for extreme areas due to the openness of the cowl.
Key features & benefits:
- Low Pa Resistance: Large free vent area with low pressure/airflow resistance.
- Twin-Walled Pipework: Ensures robust insulation and includes an integral condensation drain.
- Accommodates Ducting up to 166mm: Designed for seamless termination through a flat roof to ducting with a diameter from 110mm to 166mm.
- Material Compatibility: Available in most materials, offering flexibility to match any project.
Application:
- Flat Roof Ventilation: Suitable for ducting up to 166mm.
- Heat Recovery Units: Ideal for efficient heat recovery systems.
- Residential Buildings: Perfect for home ventilation solutions.
- Kitchen Extracts: Efficiently manages kitchen ventilation needs.
- For roof coverings : • Asphalt • Built up felt • EPDM • Bitumen • GRP roofs
Flat Roof Terminals - OFT5
The OFT 5 insulated terminal range is expertly designed for use with heat recovery systems and high-volume extract fans, accommodating both mechanical and natural (passive) ventilation installations. With its superior insulation above the roof space, it significantly reduces the risk of condensation. The internal spigot measures 166mm (excluding the OFT 5 180mm), with additional reducers provided to ensure versatile application. Note that the external height of all OFT 5 models is fixed and cannot be reduced.
Key features & benefits:
- Low Pa Resistance: Large free vent area ensures minimal pressure/airflow resistance.
- Enhanced Insulation: Fully insulated up to the cowl, providing higher insulation value.
- Accommodates Ducting up to 180mm: Designed for seamless termination through a flat roof to ducting with a diameter from 131 mm to 180mm (Asphalt only)
- Durable Construction: Features a 2-piece stack with an aluminum flange for durability and ease of installation.
Application:
- Heat Recovery Units: Optimised for efficient heat recovery system integration.
- Kitchen Extracts: Effectively manages high-volume kitchen ventilation needs.
- Versatile Ducting: Allows termination through a flat roof void to ducting up to 180mm when used with reducers.
- For roof coverings : • Asphalt • Built up felt • EPDM • Bitumen • GRP roofs
