02 · Materials
Timber or aluminium clad timber windows?
Rationel exclusively use timber, but for enhanced durability and reduced upkeep, we also provide aluminum-clad frames. Timber windows are an excellent option for both contemporary and classic residences. The incorporation of solid timber at the heart of our frames ensures exceptional thermal and acoustic efficiency. Alu clad windows retain the same solid timber core while introducing external aluminum cladding. This cladding significantly prolongs the lifespan of your windows and grants you windows that demand minimal upkeep, allowing you to effortlessly relish their benefits.
