Air conditioning , duct and pipe lagging

Pipe lagging is made of 100% closed-cell polyethylene foam. It has a low water vapor transmission rate making it excellent in insulating both cold and hot water pipes. Pipe lagging is used to insulate pipes against heat gain or heat loss and prevent condensation on cold water plumbing and has an operating temperature of -40C and +90C.Its close-celled structure allows it to reduce unwanted plumbing noises, prevent condensation, corrosion and maximizing energy saving.
Our pipes come in both reflective finish and white finish, and is available in a full range of diameters to suit Copper, PVC, PPR, galvanized steel and stainless-steel pipe sizes.
For severe exposure especially rooftop applications, cladding should be used.
When should your plumber use pipe lagging?
There are two main uses for lagging, and the material chosen will depend on what the main application of the lagging is for:
ACOUSTICS: Lagging is designed to contain the intrusive noise generated by the turbulent flow of waste-water through piping and fittings. This lagging comprises a noise barrier to contain pipe-wall vibrating noise. There are several types of materials used for this purpose, including loaded vinyl and convoluted foam. Each material will have a U-Factor, which is a performance rating measuring how well a given material prevents heat from escaping.
THERMAL INSULATION: This pipe lagging is normally a highly flexible elastometric material fitted around metal pipes to reduce the movement due to thermal changes in the pipe.

HVAC {Heating, Ventilation and Air Conditioning} systems are some of the biggest consumers of energy. Uninsulated or poorly insulated ducts lose through conduction 10%-30% of the energy used to heat and cool a building. The HVAC system then has to compensate for the heat loss/heat gain by conditioning additional air. This added conditioning raises energy consumption and consequently, the energy bills.
This particular duct wrap is thermally insulated made of closed cell polyethylene foam fused with reinforced aluminum foil facing. It’s closed cell structure ensures prevention of condensation while offering excellent insulation against heat loss or heat gain.
Duct wrap is ideal for circular and rectangular ductwork. This solution is recommended for service temperatures of up to 95C. The thermal insulation solutions are often applied to air conditioning, warm air and extractor ducts, located in plant rooms or externally.
Apart from thermal properties, it also delivers acoustic performance which can be desirable for applications to ducts that carry fluids, gases, or particle solids at high velocities.
