Installing barbed fittings

Barbed fittings are designed for use with low pressure pipe, such as drip watering systems. The barbed fittings are low cost and can neatly be installed inside the pipe using hot water.

Before fitting barbed connections ensure that the pressures used in the system will be below 4.0 bar (drip systems usually operate at around 1 bar) and are only designed for above-ground installations. Barbed fittings can only be used with soft walled above ground pipe - generally this is soft enough to distort when squeezed hard.

Green Walls improve air quaility by up to 60%

According to a study by Lancaster University, the addition of green walls in city environments could reduce the amount of particulate matter (PM) by 60% and the amount of Nitrogen Dioxide (NO2) by 40%.
