since 2005.

KLH UK was formed in 2005 as a specialist supplier of cross-laminated timber panels.
We are supported by two manufacturing plants in Austria combining the experience of 20 years of producing panels with state of the art technology. Our business has delivered 30,000 projects across 30+ countries since the first KLH panels were produced in 1999.

Our customers value our collaborative and can-do approach. Our hope is that you enjoy the experience of working with KLH UK and taking advantage of our 15 years of experience delivering CLT projects to the UK market.


The growing importance of environmental and energy issues has increasingly moved the use of wood as a renewable construction material into the foreground of modern, ecological building culture. And for sound reasons: Timber is naturally carbon-neutral and energy-efficient in every respect.

'Constructing with KLH® is therefore a valuable contribution to climate and environmental protection. With its PEFC certification, KLH® guarantees to exclusively source the valuable raw material of wood from sustainably managed forestry.

In the production of its solid timber boards, KLH® focusses on contemporary, energy-saving and environmentally friendly production methods. Their production is also entirely harmless for our employees and has no effects harmful to human health whatsoever. KLH® - CLT elements comply with emissions class 1. They can be unhesitatingly disposed of thermally and do not leave behind more residue than non-laminated timber when burned.

Technical Approvals, Certificates and Eco-labels


As a project partner, we see our co-operative attitude as an essential part of our philosophy. As a team, we work across departmental disciplines, both internally and externally.

We really wanted to say thank you to everyone who has been involved in getting us this far. We have been really excited to see the structure go up and the on-site team have done an amazing job. The CLT looks great.

I would like to record that I have been very impressed with your work on site and the efficiency of your construction team. The finished product is exactly as expected and was completed ahead of programme. Thank you for the efforts of your team.

Mayfield School are delighted with the new buildings. Innovative use of space and light in the atrium areas and other specialist classrooms will enhance the possibilities available to our staff and students.
The Sixth Form is designed not only to give a real feature (Heller-Up staircase), but is also a practical and useable large space which can be used by the whole school for various activities. The new building and external areas have created a real ‘WOW’ factor for our community as a whole.

Allison Greenwood | Deputy Headteacher | Mayfield School

The Mayfield School Project was delivered on time and within budget. It is to an excellent quality of workmanship which surpassed the expectations of the client team and the end user. The building’s design is rational, durable and above all maintainable which will ensure that Mayfield School will continue to provide teaching excellence within the London Borough of Redbridge.

Steve McConaghy | Senior Construction Project Manager| London Borough of Redbridge

I am the HT of a school in the UK which has been constructed using CLT. I am tremendously impressed with the very calm and purposeful learning environment that has been created. The students are so proud of the building and the exposed CLT is a major factor in this as it gives a high-end quality finish not common in schools in the UK. The CLT construction method enabled the building process to be rapid which was a major factor in us moving in on time.

Keir Smith | Head Teacher | William Perkin C of E School

We are completely delighted with the CLT!!! It’s been very exciting seeing our project in the factory and then going-up on site so quickly.
We love the exposed CLT walls and the character it gives the interiors – we can’t wait to move in. I think that the KLH team has been excellent throughout, from first contact, through the quotation stage to shop-drawings and the on-site erection crew – everyone has been very professional and helpful at all times. It has been a pleasure working with you all – I would be very happy to use KLH again in the future.

There is a great ambience in occupying a CLT school and it generates interest and a positive atmosphere with students, staff and visitors. Would definitely recommend it to another school.
