THERMOFLEX® is GT Globe's line of highly efficient insulated PEX pipes. Specially designed to respond to the most intensive environments and climates, the PEX pipes are insulated with almost 5 inches of high quality, closed cell polyethylene foam which provides thermal performance and protection against water migration. The two GTPEX® or GTPEX-R® pipes are used for supply and return. GTGlobe Industries Research and Development team has created this high-tech foam under specific criteria in order to reach the maximum insulation performance.

The shell material is a virgin plastic corrugated tile pipe that prevents environmental water, harsh environmental conditions or particles to get into the system which could interrupt the efficiency of your installation. The heavy duty tiles also prevent the heart of THERMOFLEX® to be compressed which will also lose its thermo efficiency. The pipe should be installed underground for maximum insulation efficiency. Usage of THERMOFLEX® offers prime efficiency and flexibility in your most simple to most complex installations
