Slim profile
A minimalist exterior and larger glazed area allow more daylight into the room.
A new generation timber-aluminium window
More light.
Less frame.
AruAL SlimLine combines Nordic timber, weather-resistant aluminium and an exceptionally slim profile. A contemporary timber-aluminium window that gives architecture more room to breathe.
02 / Benefit
The AruAL SlimLine construction reduces the visible frame and increases the glazed area. The result is more daylight, cleaner facade lines and a calmer interior - without compromising the warmth of timber or the durability of aluminium.
A minimalist exterior and larger glazed area allow more daylight into the room.
The natural, custom-finished interior surface brings the warmth of timber into the room.

Triple glazing with tested air permeability, wind resistance and watertightness.
03 / Models

Interior profile options
Choose the timber interior profile that best suits your design. Both options retain SlimLine's characteristic slender appearance. There is no separate glazing bead on the inside - the minimalist integrated profile creates a clean, continuous surface.

04 / Detail
On the outside, aluminium profiles cover the complete sash and frame. The aluminium cladding can be finished in a suitable RAL colour, with a choice of standard, semi-matt or textured surfaces. Inside, the timber profile is available with either a square edge or a 15-degree bevel and can be finished in RAL colours or translucent stains to suit the interior.
05 / Inspiration
Large glazed areas and slim profiles complement both Nordic timber homes and clean-lined contemporary architecture.
