02 / Benefit

A window does not have to frame the view.
It can set it free.

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.

01

Slim profile

A minimalist exterior and larger glazed area allow more daylight into the room.

02

Timber inside

The natural, custom-finished interior surface brings the warmth of timber into the room.

03

Aluminium outside

The weather-resistant exterior cladding reduces maintenance and offers a wide choice of colours.

04

Made for Nordic conditions

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

03 / Models

One design language.
Four solutions.

AruAL SlimLine timber-aluminium windows are available in four models. Begin with the opening direction: the 78 mm profile is slim and versatile, while the 92 mm profile suits projects where greater construction depth and energy efficiency take priority.

Interior profile options

Modern or Softline?

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.

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.
