NeatHeat baseboard front cover is made of polymer and the end caps are ABS plastic. They are melt proof until approximately 460 degrees F. You can save yourself up to $75 per hour in labor plus the cost of material by installing NeatHeat instead of having a plumber install new baseboard throughout your home. You can install NeatHeat throughout the entire property in less time and without specials tools as it snaps on over the existing baseboard heater. NeatHeat will never rust or need replacing. It doesn?t have any sharp edges and helps protect against children?s and grandchildren?s fingers touching the sharp fins inside.
