Decorative board WANUT are made from extruded polystyrene (XPS) which is extremely thermo resistant material. The effect of even surface is achieved by using a process of constant extruding of the polystyrene by adding an expanding agents, which allows the production of desired width (20-200mm). The material is then cut and packed in various shapes and sizes. The final finish is made by firm polymeric resins according to the future application of the board.
The produced material is hardened ,homogeneous and stable foam with closed (> 95 %) polyhedral cells ranging from 0.1 - 0.4 mm in diameter and a wall thickness of only 1 micrometer . Accordingly , only 10% of the product volume is solid , and the remaining 80% are occupied by gas. / which determine the high levels of insulation /.The insullation with our decorative boards WALNUT is specific due to its minimal water absorption, high compressive strength and dimensional stability. Our boards are extremely fire resistant in combination with any building materials.
According to the latest EU regulations, the material used for our decorative boards, do not affect the UV protective stratospheric ozone (ODP=0). The greenhouse effect (minimal GWP) is at extremely low level, which does not interfere with the thermal insulation characteristic of our product.
Application of the insulation boards WALNUT:
1. Insulation for interior design or accenting design - please choose an interior option when placing an order
2. Facade insulation /remediation of buildings/ - please choose an option for exterior when placing an order
3. Ceiling insulation - please choose an option for exterior when placing an order
4. Sound insulation of interior walls - please choose an option for interior when placing an order
5. Sound insulation of facades - please choose an option for exterior when placing an order
Important: Please choose the size and the application of the WALNUT boards (exterior or interior) from the drop down menue when placing an order.
Please check the insturction for INSTALATION in the main menue of our website.
