2. 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)

3. 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.

8. 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

9. Conventional process Welding
Thickness (mm) 80 160 160
Lambda (mW/mK) 33 38 33
Challenge Solution

The thermal welding of different building products offers new potential
in the construction industry.
Excellent compressive strength
outstanding lambda values
Neopor is the enhancement
of Styropor
