Flat Roofing Ventilation, Terminals & Cable Entry Systems FAQs

Why is ventilation important in a flat roof?

Proper ventilation helps reduce the build-up of condensation and moisture within the roof structure. This can help protect insulation, timber components and roof coverings from long-term damage while improving the overall lifespan of the roof.

What is a flat roof breather vent?

A flat roof breather vent allows air to circulate within the roof void, helping to reduce condensation and maintain a healthier roof structure. Breather vents are commonly used on cold roof constructions.

What is the difference between a breather vent and a roof terminal?

A breather vent is primarily designed to provide ventilation to the roof void, whereas a roof terminal is typically used to terminate extraction systems, soil vent pipes or mechanical ventilation ductwork above roof level.

What is the Ubbink OFT2 Flat Roof Vent used for?

The Ubbink OFT2, often referred to as a mushroom vent, is designed to provide roof void ventilation and help prevent condensation build-up within flat roof constructions.

What are the Ubbink OFT1, OFT4 and OFT5 terminals used for?

These flat roof terminals are designed for a variety of ventilation applications, including mechanical extract systems, soil vent pipes and other ventilation duct installations requiring a weatherproof roof termination.

What is the Ubbink Ventus Flat Roof Terminal?

The Ubbink Ventus is a high-efficiency ventilation terminal designed to optimise airflow while maintaining a weatherproof roof penetration. It is suitable for a range of ventilation and extraction applications.

Can these products be used with MVHR systems?

Many flat roof terminals can be used with Mechanical Ventilation with Heat Recovery (MVHR) systems. Always check the product specification to ensure compatibility with your particular ventilation system.

What is a cable and duct entry terminal?

A cable and duct entry terminal provides a weatherproof route for cables, pipes and ductwork passing through a flat roof. They are commonly used for solar PV systems, heat pumps, electrical services and ventilation installations.

Can I use a cable entry terminal for solar panel installations?

Yes. Insulated cable and duct entry terminals are ideal for routing solar PV cables through flat roof constructions while maintaining a secure and weather-resistant seal.

Are cable entry terminals suitable for air source heat pumps?

Yes. Many cable and duct entry terminals feature a large internal diameter, making them suitable for insulated heat pump pipework and associated electrical cabling.

What are flat roof pipe collars used for?

Pipe collars are designed to create a watertight seal around pipes passing through a roof covering. They help maintain the weatherproof integrity of the roof while accommodating service penetrations.

What are solar panel support tubs?

Solar panel support tubs are designed to provide a stable and secure mounting base for solar PV systems installed on flat roofs. They help distribute weight and can be used with ballast systems where appropriate.

Are these products suitable for all flat roofing systems?

Many ventilation terminals, breather vents and cable entry systems are suitable for use with a wide range of flat roofing systems, including felt, EPDM, GRP and single-ply membranes. Always check the manufacturer's technical information before installation.

Do these products include fixings?

Fixings vary by product. Please refer to the individual product description and technical data sheet for details of what is included.

Can these products be installed on commercial buildings?

Yes. Many of the products within this category are suitable for both residential and commercial flat roof applications.

How do I choose the correct flat roof terminal?

The correct terminal will depend on its intended use, such as roof void ventilation, mechanical extraction, soil venting, cable entry or ducting. If you are unsure which product is best for your project, please contact our technical team for assistance.
