Modern design is about innovative, non-traditional shapes and materials that create an atmosphere of style and sophistication. RED, our acronym for Rectangular European Design, has set the standard for custom linear gas fireplaces. Our Red 40 ST is an amazing See-Through version of our Red 40 with the same variety of stone and glass media options, enhanced accent lighting and porcelain or granite refractory liners. With 21 variations of options, a cleaner design and the brand promise – No one builds a better fire.
