Page 1 of 3 Aquatherm Advanced The Aquatherm Greenpipe Advanced and Climatherm Advanced systems include a thermal, UV, and vapor barrier, with a thickness ranging from 5/16"to 5/8". This barrier serves as suitable insulation in applications where building codes require the pipe the to insulated. In certain applications, the barrier can also help the piping system meet the 25/50 FSI/SDI requirements.
- Before beginning the fusion process, the barrier covering the part of the pipe that will be fused must be removed.
- Using the marking guide, mark the proper welding depth on the barrier. Then mark the barrier 1/2" to 1" further away from the end of the pipe. This second mark will help ensure that the barrier does not come into direct contact with the welding tool.
- Make an incision lengthwise in the barrier, running from the second mark to the end of the pipe.
- Using the second mark as a guideline, make a smooth cut around the circumference of the pipe. When finished, pull away the barrier at the end of the pipe, exposing a usable welding surface. It is important to remove enough of the barrier so that it will not be exposed to the welding tools during the fusion process.
- Once the barrier is removed, proceed with the heat fusion as outlined, taking care not to damage the barrier.
- Be sure to check the newly exposed barrier for a complete seal. If the cutting or fusion processes have damaged the bond between the barrier and pipe, it is important to reseal the barrier with a suitable fire-rated tape.
