Vevor's Aluminum Heat Transfer Plates are perfect for improving heat transfer in floor heating systems. These plates are designed for even heat distribution from 1/2" PEX tubing. Featuring a cuttable plate design, use tin snips to freely cut the plates and customize the length in accordance with your needs. The U-shaped channel easily snaps on to 1/2 PEX tubing and the channel can be widened with pliers. The plates are 0.016" thick and can be effortlessly stapled.
