Reynaers SL 38

Reynaers SL 38 is a system for the manufacture of super insulating and ultra-fine joinery. This system not only offers solutions for replacing old narrow-profile steel joinery, but also meets the requirements of modern and minimalist architecture. Thanks to the excellent thermal qualities and the three design variants, this system allows more than ever the anticipation of architectural trends.
