Ducting Solutions for Home Ventilation Systems
A ventilation system is only as good as the ducting used.
BPC Ventilation supply the most comprehensive range of quality ventilation and duct solutions and we can design a system to suit any type of property.
There are two types of ducting solutions: The Radial System or the Branched System
Radial Semi Rigid Ducting:
Radial ducting is the latest innovation on ventilation systems and can provide a quieter and more efficient ventilation system compared to rigid ductwork.
Radial Ducting is a system of smooth bore pipes which are crushproof, semi flexible with zero air loss. The pipes have an anti-static and antibacterial lining which individually connects each room to a manifold and are available in both circular (75mm or 90mm) and oval (51mmx114mm) fittings. Radial ducting is suitable for any type of property; including timber framed houses, passive house approval homes and can be used in areas with limited access.
- Zero air leakage ductwork (pipe ends are mechanically fitted with rubber seals)
- Low air resistance
- 50 percent faster installation rate than traditional branch systems (PVC/metal)
- No crosstalk between rooms (Quieter)
- Smaller pipework than tradtional branch systems
- No sealants required
- Hygienic smooth inner surface
- Easy to install
- Easy to clean
- supplied in 50m coils
- crushproof up to 16 Kn/m
- SAP appendix Q recognised
- Up to 85% less connections than traditional Rigid Ductwork
- Suitable for DIY installation
- Installation recommended below loft insulation to improve heat retention compared to older systems
Do not confuse this ducting with flexible or semi rigid aluminium ducting.
Rigid/branched ducting is commonly used and is a cost-effective ductwork solution on ventilation systems.
Branched Ducting a system of round or flat PVC or EPE rigid ductwork which are typically 150mm or 125mm which branch out with T-pieces into various rooms. PVC Rigid ductwork has been used for over 50 years in domestic installations.
- Available from 100mm to 300mm diameters
- Cost efficient
- Excellent air flow rates
- PVC range suitable for DIY installations
- Suitable for exposed locations
- SAP appendix Q listed
- Can be commercially cleaned
- Galvanised metal suitable for traditional systems
- Installation above the loft insulation and insulated separately is recommended
- Galvanised metal has high crushability
- PVC rectangular range available for areas of limited height.
Round PVC Piping (100mm, 125mm or 150mm)
The most traditional form of ducting pipe and has excellent airflow with minimum pressure loss
Flat PVC Piping (204mm x 60mm or 220mm x 90mm)
Used between studwork walls and below concrete ceilings to allow for ceiling heights to be maintained.
Thermal ducting is commonly used within the Radial Duct System and is constructed of EPP foam which provides a quality air supply with a high thermal resistance.
- Easy to install with a simple pushfit
- No need for extra Rockwood or foil wrapping
- No requirement for additional clamping
- Very low leakage
- Full range including round and rectangular solution
Round EPE Foam Pipe (125mm and 160mm)
Flat EPE Foam Pipe (220mm x 90mm)
Ranging from 100mm to 200mm insulated flexible ducting is used for light duct applications and is available in various types (not recommended or approved for installation on new houses)
- Insulated Aluminium - 25mm foil faced insulation with a aluminium core, used for numerous types of ventilation systems including MEV units and extractor fans in cold areas
- Insulated Acoustic aluminium - 25mm foil faced insulation with a perforated inner core, used as silencers to ventilation units and as treatment towards noise transfer between room
- PVC - Not normally used in quality ventilation systems
- Aluminium - Normally used for final connections between solid rigid ducting and air valves
- Combi - PVC coated aluminium for better durability, normally used for final connections between solid rigid ducting and air valves
