Benslow Lane by Truck CLT – WUFI analysis, Woodfibre insulation, Air and windtightness by Partel

Trunk CLT provided a full design, engineering, and supply and erection service for this detached house in Hertfordshire. Trunk CLT is headed by Mike Jacob and Jim Johnstone. Mike is a Chartered Construction Manager, and Certified Passivhaus Tradesperson, director at Trunk low energy and has worked in the emerging low energy construction sector for many years. Jim is a CLT and solid timber construction industry specialist. Jim has extensive experience delivering groundbreaking bespoke one off and multi-storey timber projects in London, Nationwide and abroad. It’s a positive blend of technical, practical and project management skills which ensures real quality of construction  together with passivhaus standards.

With extensive forward planning at each junction Truck CLT have been able minimise the heat losses from both a an air tightness and thermal bridging point of view. The building has a complete CLT structure with 180mm to 160mm of Schneider Holz wood fibre insulation, The building fabric is secured with a range of airtight tapes and high performance membranes all supplied by Partel.  This level of detail is consuming but where these points can slow down the project they are critical towards achieving long term efficiency and a safe building fabric. Also Truck CLT always makes up for this in other areas like for instance the projects principle structure was erected in just two days, admirable to say the least!

​It’s one of the nicer, and technically solid projects we’ve been involved in recently. It’s also fantastic to see how the finishes can be exactly as desired.
