What is Styrodur®

Styrodur® can look back on more than 50 years of experience at BASF in Ludwigshafen and belongs to the group of extruded rigid polystyrene foams (XPS). Styrodur®

has a European market focus.

Key benefits of the insulation board:

Low water absorption through closed-cell content

High compressive strength (300 kPa, 500 kPa, 700 kPa)

Typical applications of Styrodur®

3

Perimeter insulation (exterior insulation for building elements with ground contact)

Floor insulation

Flat roof and inverted roof insulation

Insulation of thermal bridges

Styrodur® can be used in almost all structural and civil engineering applications.

Challenge Solution

8

Maximum extruded board thickness was 200 mm

German Energy Saving Ordinance (EnEV) partly requires greater thicknesses and better thermal conductivity

Contactless thermal welding of thin boards to create a thick board

Challenge Solution

Advantage: Better lambda values of the thinner boards are also valid for the welded board

Conventional process Welding

Thickness (mm) 80 160 160

Lambda (mW/mK) 33 38 33

Challenge Solution
