Why are extruded polystyrene board widths mostly 600mm?

Expanded polystyrene sheets can be customized in length due to their continuous extrusion process. Previously, the width was limited to 600mm, but with technological advancements, it can now be extended to 1200mm. As for thickness, it ranges from 10mm thin to a maximum of 100mm thick.

What are the specifications of the extruded foam board?

Radiant Floor Specifications: 1670*600*20mm, 1670*600*30mm, etc.

Specifications for thermal insulation in construction: 2000*600*200mm, 2000*600*30mm, etc.

What are the flame-retardant properties of extruded polystyrene?

Different standards have varying classification methods. Extruded boards are commonly categorized by their flame retardancy into B1, B2, and B3 levels. B1 is flame-resistant (oxygen index greater than 30%), B2 is combustible (oxygen index greater than 26%), and B3 is highly flammable.
