	HT-300 Pipe Support System Also available with the HT-300 Insulation System is the engineered pipe support. This support can be engineered to withstand pressures up to 1,695psi using the 2# density HT-300 insulation. This allows for continuous use of a single insulation for an entire project and eliminates the "thermal shorts" that can be caused by cal-sil, cellular glass and other expensive products with much higher k-factors (lower R-values). >Photo courtesy of a HiTHERM fabricator.
