Holzraum System creates a Single Integrated Manufacturing Model combining structural, building fabric, energy performance, manufacturing and mechanical systems perspectives and aligns them with the project stakeholders' goals.
Holzraum System works with architects, engineers, builders and developers and connects them with our manufacturing processes and efficiencies in order to provide building envelope analysis and consulting as needed, resulting in a complete integration of project design intent, passive house principals and cost-effective offsite manufacturing. Holzraum System keeps the envelope design and planning process connected - always maintaining alignment between client, engineering and manufacturing perspectives. As we create a precise and comprehensive single 3D model of your structure, we apply our building science training and Wufi static and dynamic software tools. This eliminates thermal bridging, achieves superb air-tightness, and delivers highly vapor-open moisture profiles in our exterior wall and roof assemblies: eliminating risks of mold conditions and assembly decay and assuring the safest, healthiest indoor air quality possible.
When the S.I.M.M. is complete, a detailed set of geometry drawings is prepared and reviewed by the project's structural engineer, architect and builder to ensure the whole team agrees with design intent and fabrication strategies. Once the drawings have been approved for fabrication, Holzraum System creates machine files and factory instructions from the S.I.M.M. to ensure that every aligned perspective is manifest in the delivered panels and loose parts.
Holzraum System® marries high-performance wooden building envelope design and translation for off-site manufacturing with interpretation and advocacy for designers, developers, owners, and manufacturers.

Holzraum System Performance Envelopes
Our envelopes are built with only wood-based materials allowing nature to deliver extremely high-tech benefits that synthetics just can't touch.
Vapor Open Exterior Insulation
Wood fiber’s natural ability to store and release moisture and its' high vapor permeability of 20 perms allows the wall and roof assemblies to provide between 2x and 4x the drying capacity when compared to outside layers for typical plywood or OSB sheathed assemblies.
Health and Indoor Air Quality
Indoor air quality starts with how the structure is built and what products were used to build it. Holzraum System's use of only natural and fully breathable layers in our wall and roof assemblies insures that synthetic chemicals are not introduced into the structure and that unhealthy conditions like mold and rot won't develop during occupancy.
Thermal Storage Capacity
Compared with conventional insulation materials like glass wool or foam, wood fiber insulation comes with an especially high density. This creates a phase shift or delay in thermal transfer time through the fabric of the building so that the midday temperatures only reach the internal side when it's already cooler outside.
Moisture Management | Hygric Buffering
Holzraum wooden assemblies are hygroscopic, meaning they can absorb, store, and redistribute water - acting as a moisture buffer. When the air is very dry, the materials will release moisture into the indoor air (by evaporation). Eliminating low permeability layers like foam insulation allows the movement of excess moisture through the envelope instead of trapping it within the wall or roof assemblies where it can cause problems like mold, rot, and reduced insulating capacity.
Carbon Sequestration = Carbon Smart
Building construction and operation represent a large portion of annual CO2 emissions. Unlike concrete, steel, and other synthetic materials which release large amounts of CO2 during production, wooden assemblies hold carbon in their structure, significantly reducing your project's embodied energy footprint while also reducing operational energy by employing passive house strategies.
Chain of Custody Material Sourcing - PEFC Certified
A critical requirement to delivering our envelope's extremely low carbon footprint is to ensure sustainable material sourcing. All structural and non-structural framing elements in Holzraum System interior/exterior wall panels, roof panels and floor panels are manufactured using PEFC certified materials. www.pefc.org
