Timber windows: DOMUS, Rationel AURA, Rationel FORMA
DOMUS the natural window with the modern expression
DOMUS windows and doors are made of a sturdy construction where natural timber is desired inside as well as outside. The design of DOMUS is especially suited for modern residential construction and refurbishment of detached houses from the last 30-50 years.
Rationel AURA enjoy the energy from natural timber
Our new energy-contributing AURA window is specifically designed for Passive House and Low-energy buildings. AURA allows you to combine the natural look with a future-oriented, pure design for modern buildings. AURA ensures high levels of incident light and solar heat, the best insulation available, and thus free heat and, not least, a healthy indoor climate. The window comes with security ironmongery as standard.
Rationel FORMA natures own materials inside as well as outside
Today it is possible for older and classic homes to be refurbished to enjoy the advantages of energy-efficient windows. Our Rationel FORMA range features all-timber windows with narrow, non-continuous glazing bars. Also ideal for new builds if a classic expression is desired.
