Quiet-Vent Metal 45° Bend With Seals
Product Part Number
125mm - QV-B45125M
150mm - QV-B45150M
180mm - QV-B45180M
Quiest-Vent 45° bend metal is constructed of galvanised metal, it uses 2 male spigots which will fit within flexible hose or round pipe.
-Can be use with galvanised steel spiral ducting (round metal ducting - P100M-1)
Our metal ducting is manufactured in the UK with top quality materials that will supply a durable product suitable for domestic and commercial systems
It is perfectly suited for ducting your ventilation system, kitchen extractor fan, bathroom fan or in-line extract fans
It can be used as a part of a long ductwork run for a variety of purposes including whole house ventilation, passive stack vent, positive input, air conditioning, HVAC, and heat recovery systems.
Galvanised metal ducting is suitable for use in all buildings to provide superior airflow performance vs. comparative size rectangular or flexible PVC or Aluminium duct. It is suitable to use in compliance with Part F Building Regulations. Metal ducting is best suited for larger ductwork due to its superior strength.
Compatible with most other lead manufacturers for galvanised metal ducting
To provide the best performance in airtightness and durability we recommend you provide greater mechanical strength to a joint by using a combination of plastic ducting sealant and aluminium duct sealing tape
- Apply duct sealant to the male fitting
- Push together
- Apply aluminium duct sealing tape over joint
Insulation of Ductwork
It is important that any ducting located in colder areas, such as loft spaces, are always insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/ (m.k) or less.
This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space.
If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm rockwool
It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations
