The terrace base stabilizes the support and also protects sensitive surfaces such as roofing felt. The system is easy to install, user-friendly, and built to withstand Nordic climates. The support height is flexible and adjustable from 27 to 287 mm.
All components of the Knudsen Terrace System – except the terrace base – are made from 100% recycled material sourced from the food industry, making the system both strong and environmentally friendly.
Unlike traditional solutions such as wooden wedges, plastic wedges are unaffected by moisture, cold, or mold. Knudsen Kilen products also have a documented lifespan of at least 75 years.
An EPD (Environmental Product Declaration) is available for all products, allowing the system to be used in sustainable, certified construction projects.



The Knudsen Terrace System is frost-proof and weather-resistant to handle the Scandinavian climate.


Transform your tired old terrace into the perfect outdoor space
The terrace system can be used on most stable and pressure-resistant surfaces as well as on roofing felt.
The terrace sole stabilises the modular structure on uneven foundations and protects vulnerable surfaces.
