Bring daylight through the wall – Smart, efficient, and powerful
Intura side wall system
In many properties, especially older homes, commercial buildings, or areas with strict planning rules, adding a window or direct skylight is simply not possible. The Intura SunTube side wall System solves this problem by guiding light horizontally into hard-to-reach rooms—without structural alterations to the facade or roofline.
Our system is suitable for both residential and commercial buildings.
Typical applications
- Basements and underground rooms with no access to exterior walls
- Corridors, hallways, and stairwells deep within the building
- Internal bathrooms or utility rooms without windows
- Facades where window placement is restricted or undesirable
- Heritage buildings where visual integrity must be preserved
Product features
- Compatible with the SunTube daylight system
- Reflective, rigid aluminium tubing for maximum light transmission
- Includes a side wall module for horizontal light redirection
- Wall diffuser with sleek, low-profile design for clean interior finish
- Expandable with the EcoPower insulation element for superior thermal performance
Diameter Ø25, Ø35 and Ø55
The Intura SunTube, available in diameters of Ø25, Ø35, or Ø55 cm, is a versatile daylight tube perfect for both residential and commercial spaces.
The Intura SunTube side wall daylight system is a smart daylighting solution designed to transfer natural sunlight horizontally through a wall or facade—ideal for spaces where traditional skylights or windows are not possible.
This system is engineered to channel daylight from a roof-mounted dome through a highly reflective tube and then redirect it sideways through a wall-mounted ceiling diffuser. It’s the perfect solution for bringing daylight into basements, internal rooms, or buildings with restricted facade design.
"Let daylight reach the darkest corners of your building - through walls, not just roofs."
Energy-efficient and sustainable
The Side Wall Daylight System doesn't just enhance comfort—it also reduces the need for artificial lighting during the day. Combined with the optional EcoPower insulation element, it delivers excellent thermal efficiency, helping to maintain airtightness and support low-energy building standards.
Installation & compatibility
This system is easy to integrate into new builds or retrofits. It connects seamlessly with other SunTube components, including roof domes, elbows, and ceiling diffusers. The side wall module allows for flexible tube routing and is ideal where a vertical drop is not feasible.
