AEROFLEX closed cell EPDM foam pipe insulation, also known as pipe lagging, insulates air conditioning, copper refrigeration, hot water, solar and chilled water pipes. It is flexible and lightweight, so installation is easy and neat, with outstanding ultraviolet and weather resistance for outdoor runs. Ideal for all domestic and commercial insulation applications, and delivered Australia wide.
Air Conditioning Pipe Insulation
Split-system and ducted air conditioners run two copper refrigerant lines between the indoor and outdoor units, and both need insulating to stop condensation, sweating and lost efficiency. Aeroflex EPDM tube slides straight over the copper, stays flexible around bends and stands up to sun and weather on outdoor runs.
9mm and 13mm walls are the most common choices for domestic split-system lines. Thicker walls suit long outdoor runs, roof spaces and humid climates. Always check the equipment manufacturer’s installation instructions for the wall thickness they specify.

Hot Water & Solar Pipe Insulation
Aeroflex HT is the high-temperature grade, rated to 150°C, for solar hot water flow and return lines, heat pump hot water systems and hot water plumbing. Insulating hot water pipes cuts heat loss between the tank and the tap, so hot water arrives faster and the system works less.
HT tube is available in 10mm to 35mm ID to suit common copper solar and hot water pipe sizes.
Aeroflex Pipe Insulation — The Difference is EPDM
AEROFLEX is an ideal insulation for frost control on sub-zero piping. It prevents heat gain and condensation problems on chilled water and refrigerant pipelines, and it also prevents heat loss from hot water plumbing pipes

AEROFLEX INSULATION COMPARISONS
FIREGLASS
(open-cell structure insulation)
Fiberglass thermal insulation is made from compacted small glass fibers. Air occupies the spaces between the fibers which allow atmospheric moisture to penetrate into the insulation, resulting in very high water vapor permeability.
POLYURETHANE
(semi open-cell structure insulation)
PU Foam is made of polyols and polyisocy- anates mixed with HCFCs or similar gases. The cell wall is very thin and brittle, making it semi-opened cell easily. This allows much moisture penetration, which resulting in high water vapor permeability.
AEROFLEX
(closed cell structure insulation)
Aeroflex is made from synthetic elastomers based material. The elastomeric material makes Aeroflex flexible with closed cell struc- ture (mainly nitrogen gas inside), resulting in very low water vapor permeability
These 10 situations resulted in insulation failure; seven were caused by the design engineer and three by the installing contractor.
Review some of the chilled water pipe insulation failures by consultants and installers.
• The valves and unions were not insulated — guaranteed to result in condensation and dripping.
• Lack of sealant on joints of pipe insulation.
• Choice of wrong insulation — use of fiberglass, urethane, plastic foam or a cheap hardware store flexible insulation. They work great until they fill up with condensation or melt.
• Lack of commissioning — a quality control inspection is needed on all pipe insulation.
• Workmanship by the pipe fitter or carpenter or whoever was available, suggest experienced install.
• Use of the wrong hangers or the wrong insulation at hangers.
• Lack of adequate space for the insulation around each pipe — installing the supply and return pipes too close to each other will cause problems of condensation and dripping.
• The design engineer used a canned insulation spec that was obsolete 30 years ago.
• The design engineer is in Melbourne and does not understand the humidity issues in northern Australia, insulation product that may work in Melbourne may not work in Darwin.
• The specified pipe insulation was too thin.
