X-fix connects CLT!

X-fix is …

… a timber to timber coupling system for easy and fast joining of cross laminated timber Elements in wall – wall Connections or ceiling joints .

… a double dovetail shaped connector for CLT panels made from plywood without any metal.

… time saving on the building site, with just a hammer for the self tightening X-fix coupling System and the CLT Panels are clamped together 100 % accurate and form-locking.

… the future in CLT building minimizing CLT waste and speeding up onsite installation. 

X- fix News:

June 2021: SEMA Software for timber construction integrates all X-fix models into the SEMA Data Store.

See in this video link how easily you can plan X-fix in your projects with the SEMA timber construction software.

April 2021: KVD Houtbouw / BE produces wonderful solid CLT houses with its SCM Oikos from inexpensive 1.2 m standard CLT panels and X-fix.

In Turnhout / BE, our customer Kristof Van Dun (KVD Houtbouw) uses his SCM Oikos CNC system to produce wall and ceiling elements with almost no waste from 1.2 m standard panels and X-Fix. In this way, wooden structures made of inexpensive standard material can be manufactured very flexibly and individually according to customer requirements. Incidentally, Kristof buys the raw panels in winter. Ideal in view of the sharp rise in raw material prices and the long delivery times in the industry. Many timber construction companies have a CNC joinery system for 1.2 m panels. In the case of a new building, an extension or an addition, the carpenter takes away the solid construction from the bricklayer. With standard CLT and X-fix.

New X-fix C models 60, 130 and 180 mm:

In addition to the ETA 18-0254 approved models X-fix C 45 mm and X-fix C 90 mm, the new models in the lengths X-fix C 60 mm, X-fix C 130 mm and X-fix C 180 mm are being tested. X-fix C 45 mm is approved for CLT 3s from 60 mm. X-fix C 90 is approved for all CLT board structures from 3 layers.

Winter 2020/2021: Züblin Timber builds Collegium Academicum Heidelberg without screws but with X-fix – a new era in timber construction:

Picture: Collegium Academicum

Without screws – a new era in timber construction: Züblin Timber in Aichach / DE is using X-fix to build a student residence without screws. For the first time, X-fix is also used to connect glued laminated timber and structural beech. The all-wood construction for the Heidelberg student residence, designed by the architects Drexler Guinand Jauslin and planned by Pirmin Jung, does not require any screws. But over 3000 # X-fix C 90 hold the future-oriented building together. X-fix connects pillars and beams made of structural beech or glulam with CLT panels  to give the building the necessary rigidity.

2020/2021  Implenia builds KIM Inno-City in Winterthur/CH with X-fix:

A large-scale development  with X-fix planned by BDE Architects from Winterthur. After the positive experience with the “Krokodil” in Winterthur, Implenia is again building with X-fix C. The 10,000 m2 visible floor ceiling connected with 6000 # X-fix C comes from HASSLACHER NORICA TIMBER (approx. 2500 m3 CLT).


TS3  – new gastro hall for Handl Tyrol Speck – with X-fix as an assembly aid:

The catering area of the large new building of the Handl Speck company in Pians is covered by a 650m2 cross-laminated timber ceiling with the new TS3 adhesive technology paired with X-fix. TS3 technology is a revolution in timber construction. 


April 2020 Bateschwiler/ Laufenburg, CH counts on X-fix for wall and ceilings:

Video: Balteschwiler

Architects, planners and construction professionals saw a “rotating X-fix sail” at the Balteschwiler stand at Swissbau in Basel 2020. “We will supply our customers with construction kits for walls and ceilings with X-fix. We have already completed several orders for this “, says Matthias Huber, head of timber construction projects at Balteschwiler. The Reichenbacher machining center with vacuum clamping table from Balteschwiler offers the ideal prerequisites for X-fix milling.

February 2020: Belgian walls and ceiling elements made of standard CLT panels from Binderholz with X-fix:

The Belgian X-fix pioneer Kristof Van Dun shows how walls and ceiling elements for extensions and new buildings can be made from standard CLT panels with a width of 1.25 m from Binder Holz at low cost. With his SCM Oikos, Van Dun manufactures the individual parts of the walls and assembles them in the factory. Installation is quick and uncomplicated as usual. “We have four new projects in the pipeline in which we will use X-fix C 90”, reports Femke Dryts, chief technician at Van Dun.

Opening X-fix Timberdome Diemenstein on the campus of the TU Kaiserslautern 05.09.2019: Pavilion with a span of twelve meters is inaugurated. The new wood research campus of the Department of Architecture of the Technical University of Kaiserslautern (TUK) is currently being built in the Diemerstein Valley near Kaiserslautern. Its entrance is characterized by a wooden pavilion – an X-fix Timberdome – with a span of twelve meters of an area of 100 square meters.
The wooden pavilion has Dr. Christopher Robeller and his team of the DTC TU Kaiserslautern designed and manufactured. The architects worked closely with the timber construction company CLTech. The statics comes from Pirmin Jung engineers. The pavilion is unique in its kind worldwide. X-fix makes it possible.

“Crocodile” Winterthur client Implenia / CH is highly satisfied with Hasslacher ceiling systems combined with X-fix, a report from the construction site: Site manager Adrian Ulrich of the company Implenia / CH is thrilled with X-fix and the Hasslacher Norica Timber ceiling elements. “We save more than 30% of the laying time for the floors,” says Adrian Ulrich. “In addition, the X-fix ceiling connection system is qualitatively better, because X-fix automatically closes the gap between the visible ceiling elements.” Ulrich is also satisfied with the static properties of X-fix C. “An X-fix C connector can take 28 kN of shear and tensile load and is therefore more cost-effective compared to steel screws and steel sheet plates that would be necessary to absorb the enormous shear forces of the building in the storey ceilings. “

Ligna Hannover 2019,  X-fix Timberdome hosted by LEDINEK:  On the stand of the company LEDINEK, we were showing the X-fix Timberdome at the Ligna 2019 in Hanover. Many international experts acknowledged how easy it is to connect CLT components with X-fix on the construction site or in the factory in a way that saves resources and time. The current X-fix construction projects such as the “Crocodile” in Lokstadt / Winterthur were also well received by the industry. Thanks to the great Ledinek team.

Lokstadt “Crocodile” (Switzerland), X-fix bulk order for Hasslacher Norica Timber:   X-fix partner Hasslacher Norica Timber builds 20.000 m2 CLT ceilings (24 cm thickness) for customer Implenia,  in Winterthur (Switzerland).  The name of the building: the “Crocodile” in the “Lokstadt”. Over 10.000 # X-fix C ceiling connectors make the highly sophisticated sight-ceiling construction possible.  The 24 cm thick CLT panels with visible surface are connected with X-fix C without  gaps. The main advantages: enormous time savings of installation time and excellent dimensional stability
