JACKODUR® Atlas Insulated Raft System

JACKODUR® Atlas – made of extruded polystyrene foam (XPS) – is an intelligent, efficient thermal insulation and formwork system for floor slabs. The innovation part is the new, economical interlocking system, which provides thermal bridge-free insulation in all types of buildings.

The Atlas system will mitigate the key thermal bridge at the junction of the floor slab and the external walls.

Supplied as bespoke, perimeter or as standard items in the JRS option to minimize waste on site and ensure a rapid build programme whilst offering complete design flexibility.

Features and benefits:

• Lightweight – easy assembly.
• Speed of construction.
• Cut to fit individual raft design.
• Energy efficient. Bespoke U-value.
• Technically approved.

The Atlas system is available in several thicknesses to achieve the target U-Values of domestic, commercial and Passive house builds.

Available in JACKODUR® 300 kPa, 500 kPa and 700 kPa compressive strengths.
