Interior Insulation STEICOinternal Wood Fiber – Insulation Boards with STEICOinterior Coating System
In many cases, interior insulation offers a practical solution – for example, for preserving valuable facades, for temporarily used buildings, or when you need only specific rooms or apartments to insulate. With just a few centimeters of STEICOinternal wood fiber insulation board, you can achieve significant improvements.
Strong Performance, Slim Insulation
The lambda value (λ) indicates a material’s thermal conductivity. The lower the value, the thinner the insulation layer can be. STEICOinternal offers a λD value (thermal conductivity) of 0.038 W/(m·K). The new STEICOinterior coating system can be used multifunctionally as an adhesive, reinforcing, and finishing layer.
Only 6 cm Insulation for 63% Better Energy Efficiency
The U-value measures the total heat transfer through a wall structure. The lower the U-value, the less heating energy is lost. Unrenovated brick walls often have a U-value of 1.12 W/(m²·K). With only 6 cm of STEICOinternal interior insulation, this value can be improved to 0.41 W/(m²·K) – an energy efficiency improvement of 63%.
Warm Walls = Comfort and Well-being
Our sense of comfort at home depends not only on room temperature but also on the surface temperature of the walls. In uninsulated houses, walls remain cold, making residents feel chilly even in overheated rooms. The STEICOinternal wood fiber insulation system helps raise the inner wall temperature, creating a more pleasant indoor climate – and allowing for lower heating needs without sacrificing comfort.
Naturally Insulate from the Inside
STEICOinternal wood fiber insulation boards are produced using the STEICO PureWood process. In this method, the wood’s natural lignin acts as a binding agent. Only untreated softwood from sustainably managed, PEFC-certified forests near STEICO’s production sites is used.
The Institute for Building Biology and Sustainability (IBR), Rosenheim, awards its seal to healthy, environmentally compatible building materials. STEICOinternal insulation boards carry this respected certification for healthy indoor living.
STEICOinternal Saves and Stores COâ‚‚
The carbon component of COâ‚‚ is stored in the wood fibers of STEICO insulation materials, effectively removing COâ‚‚ from the atmosphere for the long term. In addition, STEICO wood fiber insulation reduces heating demand and related COâ‚‚ emissions.
For example, 100 m² of 6 cm STEICOinternal insulation stores about as much CO₂ as a small car emits over approximately 12,400 km.
STEICOinterior Complements the STEICO Interior Insulation System
All from one source: With STEICOinterior, STEICO expands its interior product line. The STEICOinterior Render L lime-based coating system enhances the performance of STEICO wood fiber insulation and plaster carrier boards. For final wall and ceiling coatings, STEICOinterior Color SI is recommended.
Building Physics Reliability
Within the coordinated interior system, STEICOinternal wood fiber boards and mineral STEICOinterior components complement each other perfectly. They are vapor-permeable, capillary-active, and moisture-absorbing, supporting a balanced indoor climate. These materials can absorb, store, and release humidity as needed. In addition, the high lime content of the STEICOinterior coating has a naturally alkaline effect.
Affordable and Fast Installation
Installing STEICOinternal insulation does not require scaffolding or cranes. Weather conditions are irrelevant, allowing work year-round. The lightweight boards are easy to handle and install even in confined spaces.
Reducing Thermal Bridges with System Accessories
The STEICO product range includes solutions for every detail:
-
For window reveals, the STEICObase wood fiber board (only 20 mm thick).
-
For connections between interior walls and ceilings, the tapered STEICOtri provides effective edge insulation.
