Under-tiling dilatation profiles are the type of profile used to eliminate problems such as expansion and contraction caused by temperature changes, depending on the material type. With its high UV-resistant, polymer-based, chemical-resistant filler, PRF.140 is the profile designed by the Evimetal family for this purpose. Thanks to its winged structure, it can be easily applied under ceramics. It has a structure that can easily tolerate situations such as expansion or contraction caused by temperature differences.
