xps foam insulation board - 1

Extruded polystyrene foam boardsFIBRANxpsare a thermal insulating material (XPS) produced from polystyrene and suitable blowing agents by the process of continuous extrusion thus forming a continuous board at the desired thickness (20-200 mm). This is then cut and packed in various dimensions and shapes regarding surface and edges.

By far most of the mass of the final product is composed of polystyrene (PS), a thermoplastic polymer of styrene which itself is a compound of carbon and hydrogen. Crystal-clear, high heat resistant general purpose polystyrene (GP-PS) is used. Small amounts of certain additives are included in order to facilitate the production process or for enhancement of the properties of the final product - like colorants and flame retardants. Foaming is achieved by adding physical blowing agents, about 5-8% of the total mass. In accordance with the latest EU-regulationsFIBRANuses agents / gases that have no harmful effects on the UV-protective layer of stratospheric ozone (ODP=0) and a marginal or non-existent contribution to the “greenhouse effect” (low or zero GWP) without perceptible depreciation of the thermal insulating properties of the product.

The produced material is a solidified, homogeneous and stable foam with closed (> 95%) polyhedral cells ranging 0.1 – 0.4 mm in diameter and having a wall thickness of only 1μm. Accordingly, a mere 3% of the product volume is solid matter the remaining 97% being occupied by gas. This results in particular low densities.

FIBRANxpsboards are characterized by their high and lasting thermal insulating property, minimal water absorption, high compression strength and dimensional stability. Ignition is not easy, compatibility with building materials like cement, gypsum, lime and sand is excellent whereas skinned and grooved boards offer superb adherence on concrete and mortar coatings
