Product comparison
COMPACFOAM combines strength with excellent thermal insulation and low weight. As a versatile construction element and high-quality insulating material, it is versatile and easy to work with standard woodworking machines (screwing, drilling, sawing, planing, milling).
The material is resistant to moisture and frost, temperature-stable up to 90°C, not brittle at low temperatures and therefore suitable for refrigeration technology. It does not swell or shrink and is resistant to ageing and rotting.
Available as sandwich panels, panels, rods or profile bars in standard formats and customized cuts. COMPACFOAM is recyclable and sustainable.

Why COMPACFOAM in timber construction?
Modern timber buildings require rot-proof solutions in the base area and at window connections. Solid wood thresholds fail when exposed to moisture. COMPACFOAM combines the processing advantages of wood with the durability of a modern technical material.
decay protection
No rotting, no mold growth
Subsequent damage to the external waterproofing leads to moisture penetration and severe damage to the load-bearing structure in solid wood sleepers. COMPACFOAM is rot-proof and permanently prevents biological infestation.
SEALING SAFETY
Permanent connection tightness
Sealing defects cause considerable consequential damage to load-bearing timber structures. In COMPACFOAM Building waterproofing materials such as membranes, liquid plastics, or bitumen sheets can be applied directly without any additional measures.
THERMAL INSULATION
No thermal bridges, optimal insulation values
Standard solutions lead to energy losses and condensation problems in critical connection areas. COMPACFOAM offers excellent insulation values to prevent thermal bridges and ensures optimal thermal protection.
DESIGN FREEDOM
Free milling for customized profiles
Conventional materials limit design freedom and require compromises. COMPACFOAM Free milling enables individual profiles to be created precisely according to design requirements – freedom in design.

Customer testimonials
„The material is completely stable over the long term. Even at high temperatures and humidity, there is no shrinkage or settling of the wall structures.“
Heiner T.
Production manager
"The material can be processed like wood, so we didn't need any expensive machines or changes in production."
Stefan H.
Design engineer
„The material is incredibly ductile without yielding. This means that even under high point loads, it always remains stable and safe.“
Enrico S.
Design engineer
FAQ
Compacfoam has very low thermal conductivity and high compressive strength. This makes it ideal for preventing thermal bridges at structural connections—such as balcony beams, thresholds, or window connections—without compromising load-bearing capacity.
Yes, Compacfoam is highly pressure-resistant and dimensionally stable. It can reliably absorb static forces, making it ideal for threshold supports, substructures, facade fastenings, or support points under wooden posts.
Compacfoam is moisture-resistant and rot-proof. It absorbs hardly any water and remains dimensionally stable even under changing climatic conditions—a decisive advantage in timber construction, where moisture protection is crucial.
Yes, Compacfoam is chemically neutral and does not react with wood or wood preservatives. It can be combined excellently with wood, e.g., as a load-bearing or insulating connecting element between wooden elements or between wood and concrete.
Compacfoam Can be worked with standard woodworking tools—sawing, milling, drilling, and screwing are all possible without any problems. This makes handling particularly easy and efficient for carpenters and timber construction companies.
Thanks to its excellent insulating properties and the prevention of thermal bridges, it contributes to Compacfoam Significantly contributes to energy efficiency and reduces heating requirements—an important factor in energy-optimized timber construction projects and passive houses.
Compacfoam is resistant to aging, dimensionally stable, and resistant to rot and pest infestation. It retains its mechanical and thermal properties for decades—even under changing loads.
Yes, due to its material structure, it appears Compacfoam Sound-insulating and can help reduce structure-borne noise transmission in wooden structures, for example at connection points or fastenings.
Compacfoam is 100% recyclable, durable, and helps reduce energy consumption in buildings thanks to its insulating properties. Combined with wood, a renewable building material, it creates a sustainable, resource-efficient construction method.
Typical areas of application include thermally separated sill supports, balcony connections, window and door connections, facade fastenings, substructures, and load transfer elements in timber frame and timber module construction. Wherever high compressive strength and good insulation are required at the same time, Compacfoam the optimal solution.
Compacfoam is available as sheets and rods (up to 6 m in length) in any format. Customized profiles are possible.
