Rationel produce timber and aluminum-clad timber windows and doors, all featuring the distinctive Scandinavian flush frame design.

​

Presently, Rationel offers two distinct design lines tailored to complement the character of various buildings:

​

• FORMA: This line is distinguished by molded beadings and slim astral bars, making it suitable for traditional buildings such as barn conversions.

• AURA: Characterized by square-edge lines, AURA is ideal for modern and minimalist projects.

​

Both design lines are available with the option of triple or double glazing units. An additional "plus" next to the line name signifies that the frame includes external aluminum cladding.

​

Rationel sources its timber from certified sustainably managed forests to ensure environmental responsibility in its production processes.
