Timber Innovations are experienced in a variety of techniques to achieve Passivhaus / ‘Near Zero Energy’ compliance. Our staff can offer an early design stage review of your plans to identify any potential challenges.
Design & Engineering
We can offer design & engineering input to improve buildability and are always happy to meet with potential clients to discuss their ideas and offer advice based on our experience. Our manufacture process is inherently flexible and we regularly design and manufacture bespoke solutions to eliminate / reduce cold bridging.
The scope of our works would normally include the complete installation of insulation & airtightness seals where appropriate and is supervised by trained passivhaus tradespersons.
High comfort, low energy
Passivhaus and ‘Near Zero Energy’ buildings provide a high level of occupant comfort while using very little energy for heating and cooling. They are built with meticulous attention to detail and rigorous design and construction according to principles developed by the Passivhaus Institute in Germany, and can be certified through an exacting quality assurance process.
We offer timber frame & SIPS solutions to meet Passivhaus and ‘Near Zero Energy’ requirements.

Our Larsen Truss Build System
A Larsen Truss is a lightweight wall extension with the purpose of creating extra wall space to house insulation. The concept was first invented in 1981 by the Canadian builder, John Larsen.
A Larsen Truss enables us to execute the following:
- Simply and effectively increase the sizing of a wall cavity on new builds, achieving high levels of wall insulation
- Reduce thermal bridging in walls
- Cut down the number of materials used in energy-efficient construction
- Add a protective air/vapour barrier to new builds
- Lessen the reliance on fossil fuels to heat homes
The Larsen truss is constructed using a structural stud (typically 38×140 CLS) and an outer ex 50×50 batten zone fixed with 11mm OSB bracing sections to significantly reduce cold bridging, specialist air tight or breathable boards / membranes are factory fitted to suit the required specification’
When alternative vapour barrier methods are used, Larsen Trusses can also be installed directly into an existing frame.
