Norwegian Cross-Laminated Timber from Splitkon

Cross-Laminated Timber from Splitkon is manufactured exclusively using PEFC-certified timber from Norwegian forests. This ensures the highest quality – tailored to Nordic conditions. Splitkon supplies the Norwegian construction industry with cross-laminated timber from one of the world’s largest CLT manufacturing facilities.

Timber is a renewable resource. Timber products, such as glulam and cross-laminated timber, therefore have a favourable environmental profile.

What is Cross-Laminated Timber?

Cross-Laminated Timber, also known as CLT (Cross-Laminated Timber), consists of cross-laminated layers of timber lamellas, or boards, assembled into solid elements. The layers are oriented at 90 degrees to each other. Cross-Laminated Timber can be manufactured in various thicknesses, from three layers upwards, depending on the applications and functions the project requires.

CLT elements provide a highly stable building component with high stiffness and load-bearing capacity. Cross-Laminated Timber can be produced in large dimensions and prefabricated into finished elements used for walls, floors and roofs in buildings of all sizes. During manufacturing, we incorporate cut-outs for ventilation, water, drainage, etc. CLT elements are assembled efficiently and are often used as stabilising panels in various structural systems.

Office building constructed in cross-laminated timber

The elements have significant fire resistance and an effective moisture-stabilising function when the elements are exposed in interior environments.

The use of cross-laminated timber has experienced steady growth in Norway and Sweden over the past ten years. Timber is the building material of the future. Splitkon has an ambition to be the leading player in the further development of cross-laminated timber. We will constantly challenge ourselves and continue the excellent work that is carried out every day in the factory, in the laboratory and in collaboration with our customers and partners.

As Norway’s only industrial manufacturer of large-scale cross-laminated timber, we deliver to commercial buildings, residential properties, cabins, schools and other applications.

SporX is located in Drammen and is one of the world’s most environmentally friendly office buildings. From the foundation to the roof terrace you will find 10 storeys built with 100% SplitkonCross-Laminated Timber and glulam.

Opportunities of building with cross-laminated timber

Splitkon AS possesses comprehensive expertise in structural systems using glulam and cross-laminated timber that surpasses most in the industry.

Splitkon’s engineers have extensive experience in the design and engineering of glulam structures for all types of small and large buildings. The combination of glulam and cross-laminated timber enables our designers to create buildings with large spans and open floor areas.

Cross-laminated timber from Splitkon is available in three different grades, depending on the intended use. Splitkon delivers cross-laminated timber without edge gluing to ensure even distribution of gaps during drying and to prevent larger drying cracks. Timber is a living material with natural variations in colour and structure, which must be accepted when using visible timber.

Visible

Suitable for permanently visible surfaces in residential and public buildings. Surface controlled, with knots and structural defects repaired where necessary

Not visible

Used in buildings without special requirements for surface quality. Surface in accordance with appearance class ‘Industrial’. May contain surface defects and glue residue.

Industrial visible

Quality for use in buildings with lower requirements (ref. visible quality) for surface quality. Surface controlled and sanded with 80 grit. May contain surface defects.

Questions and answers

The construction industry is undergoing significant change, and the need to build more sustainable buildings with cross-laminated timber is absolutely essential for us. Here we have compiled some of the most common questions.

Hva er Massivtre?

Cross-laminated timber consists of cross-laminated layers of timber lamellas, or boards, which are assembled into solid elements. Cross-laminated timber can be produced in various thicknesses, from three layers upwards, depending on the application and functions required.

Hvor store elementer kan Splitkon lage?

We can manufacture elements from 6 cm to 36 cm thick, and they can be from 2.4×6 metres up to 3.5×16 metres (For rendered surfaces: maximum width 3.2 m).

Hvordan produseres Massivtre?

We use lamellas that are cross-laid at 90 degrees to each other, with adhesive between each layer. The lamellas are then pressed together to form a large, solid panel.

Hva vil det si at Splitkon er PEFC-sertifisert?

This means we can guarantee that our raw materials come from sustainable forestry
You can read more about PEFC certification at www.pefc.no

Hva slags trevirke brukes?

We use Norwegian spruce that has been dried and strength graded according to our requirements. This comes from sawmills within a radius of approximately 200 kilometres from the factory.

Hvorfor bygge i massivtre?

Cross-laminated timber elements provide a highly stable building component with excellent stiffness and load-bearing capacity. CLT manufactured with MUF adhesive offers significant fire resistance and an effective moisture-stabilising function when the elements are exposed to interior environments.

A sustainable choice as timber inherently has no negative impact on the environment. It also creates a healthy indoor environment as exposed timber in buildings gives people a special sense of well-being.

Hvordan kvalitetssikres våre produkter?

We have our own laboratory used for testing and analysis. Here we check, amongst other things, that the timber has the correct quality upon arrival. Every single board is measured for moisture content at our facility.

At the start of our production line, the timber is monitored so that an additional check can be made to remove any defects where necessary. In accordance with our technical approval, we test both finger joints and finished elements daily to verify that they meet the requirements for strength and delamination.

Hvem leverer Splitkon byggesystemer til?

We deliver modern building systems in cross-laminated timber and glued laminated timber for commercial buildings, offices, agricultural buildings, housing, flats, schools, halls and cabins, amongst others

Hvorfor er massivtre miljøvennlig?

One cubic metre of CLT binds approximately 800 kilograms of CO2. By comparison, the same quantity of concrete produces CO2 emissions of 385 kilograms.
