CLT Material – A Natural and Strong Choice for Sliding Doors

CLT material (Cross Laminated Timber) is an innovative and ecological solid wood structure that has become especially popular in modern wood construction. Made from cross-glued layers of wood panels, CLT is precise, strong, and stable, retaining its shape excellently over time. This makes CLT an ideal choice for interior doors.

Sliding doors made of CLT material offer exceptional durability and natural aesthetics. The living surface and warm tone of solid wood make the door a striking part of the interior. A CLT door is manufactured as a multi-layered structure, with the top layer always being premium Nordic spruce, and the edges are finished to be knot-free and flawless. The structural rigidity of CLT ensures that the sliding door works flawlessly year after year.

The advantages of CLT are:

● CLT is a very sturdy and massive structure

● Excellent strength properties

● Pleasant and healthy indoor air

As a building material, CLT is a healthy and breathable choice. Indoor air remains consistent when a house is built from floor to ceiling with breathable, moisture-regulating material. Wood absorbs and releases moisture, balancing the humidity of the room air. Spruce has also been shown to have antibacterial properties.

CLT doors combine aesthetics and durability

CLT doors not only bring visual warmth to a space but also act as excellent sound insulators. This makes CLT sliding doors a practical solution for offices or spaces that require both openness and privacy. Door panels can be surface-treated, for example, with varnish or tinted according to the Teknos translucent color chart, giving them extra protection and allowing them to reflect the desired interior style.See how we implemented a CLT door solution together with a client.

CLT material is used in the Liune product family in sliding doors, surface sliding doors, and hinged doors. In hinged doors, the strength and dimensional stability of CLT enable a high-quality and premium door experience. Thanks to the solid wood structure, the doors are sturdy and silent to use, offering a strong alternative to traditional MDF or particleboard doors.

The advantages of CLT doors also include their ecological nature. The steel frame of the door is made of SSAB Zero Steel, manufactured from recycled steel by SSAB, produced with fossil-free electricity and biogas. By choosing a CLT sliding or hinged door, you are making a sustainable choice that supports carbon-neutral construction and ecological interior design.
