Available in 3 formats.
The general insulated wooden block is made of OSB 3 and includes 264 mm thick graphite EPS insulation. The U-value (insulation value) achieved is 0.15 W/m²/K.
The insulation is free to slide in order to form the tenon necessary for interlocking.
The “traditional” insulated wooden block is the most commonly used in a self-build.
