Wattens primary school

Educational facility, Tyrol

The new Wattens Primary School was successfully realized using innovative ribbed floor elements – a combination of our CLTPLUS cross-laminated timber panels and glulam products. The modern, climate-friendly school building blends harmoniously into the surroundings of Kirchplatz and today provides an inspiring learning environment for more than 200 pupils. Designed as a hybrid structure, the school combines a concrete basement level with solid timber construction in the upper floors, serving as an outstanding example of sustainable and future-oriented building. The project design, which won first place in the 2023 GP competition, was developed by ARGE Studio Lois Architektur and architect Iris Reiter. Through its successful combination of functionality, architecture, and sustainability, the new Wattens Primary School sets a strong benchmark for modern educational buildings.

Innovative solutions for modern educational facilities

ribbed ceilings are produced in our CLT plant in Steinfeld

Ribbed ceilings made of CLTPLUS in the planning stage

How are ribbed ceilings created?

A ribbed ceiling element measures over 20 m² and consists of two glulam ribs and one CLTPLUS ceiling element each.

In the joinery service centre, precise processing is first carried out on both solid wood products. The glulam ribs and the CLTPLUS ceiling elements are then joined together using screw press bonding. A joint-filling 2-component adhesive is used to ensure a durable and stable connection.

Solution approach

A special feature of this timber building is the more than 150 factory prefabricated ribbed ceilings made from CLTPLUS ceiling elements and glulam. These combine outstanding strength, enormous stability and high load-bearing capacity with low weight. Thanks to trained employees in the joinery service centre, as well as annual factory production control, these have been produced at THEURL as special solutions since 2024.

Result

A total of 405 m³ of visual-grade glulam was used for the project. Of this, 236 m³ was incorporated into the innovative glulam ribbed floor elements, while approximately 170 m³ was used for beams and columns. The structure was further complemented by more than 400 m³ of CLTPLUS floor elements with thicknesses of 120 mm and 160 mm. To ensure optimal protection during construction, the finished ribbed floor elements were fully covered with a weatherproof membrane bonded to the CLTPLUS surface. Thanks to the use of our in-house swap-body transport system, all elements were delivered efficiently, ensuring a smooth and reliable construction process.

Double columns made of glulam

On a total of 18 double columns made of glulam, numerous and very complex processes such as rebates, slots, drill holes and recesses are carried out on the joinery machines. These are necessary for the steel components, which are assembled on site.

Two stairs made of glulam wedges and CLTPLUS

For the direct connection of the floors, two CLTPLUS stairs with attached glulam wedges are prefabricated in the factory. The result: the stairs can be easily used during the entire construction period and there is no need for temporary site stairs.
