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.

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
