Description
90 degree galvanized metal elbow bend which uses 2 male spigots, which will fit inside round pipe or flexible hose. Best used with galvanised steel spiral ducting (round metal ducting - P100M-1).
NOTE: Supplied without rubber Seals
Our metal ducting is UK manufactured 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.
Compatibility
Compatible with most other lead manufacturers for galvanised metal ducting
Performance
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.
Installation
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
