Timber Frame Wall Systems

We are specialists in closed panel construction and industry leaders in the design of energy efficient timber frame panels.

All our timber frames and closed panels are designed and manufactured right here in our Elgin premises, providing a cost-effective and flexible service. Our designers use cutting edge analysis and modelling techniques to design the connections and fittings that ensure our panels can integrate seamlessly into your design.

ACJ Group is proud to have developed Them-u-wall, one of the most energy efficient closed panel systems on the market, ideal for use in passive house construction.

We can supply panels direct to you, as required.  ACJ Design, our in-house architectural services team, uses the latest BIM systems to ensure complete integration with your project.  Call us now on 01343 559327 to speak to one of our designers.
