Le PSX pour isoler efficacement les systèmes HVAC et les toitures

Cousin of expanded polystyrene, extruded polystyrene (XPS, also called rigid styrofoam) differs by its method of manufacture, which gives it specific properties. In particular, very high mechanical resistance but also to compression and water, while maintaining very good thermal insulation qualities.

Extruded Polystyrene (PSX) is a synthetic insulation produced from polymer foams. It has been specially developed for thermal insulation, so it has several insulating characteristics:

• Thermal insulation

Extruded polystyrene is composed of beads of styrene monomers extruded by a blowing agent (CO2 or HCF gas). This structure allows the PSX plates to block the flow of cold air to the interior and thus prevent heat loss.

• Sound insulation

PSX is a good thermal insulator, however it does not constitute an acoustic insulator.

• Fire resistance

Extruded polystyrene is rated E in the fire resistance classification, which means it burns rapidly on contact with flames. It also gives off toxic fumes when burned.

It is therefore not suitable for places where the risk of fire is high.

• Strength & durability

Extruded Polystyrene is a compression resistant material, it is quite sturdy and withstands extreme weather conditions. It has a fairly long lifespan, from 50 to 75 years.

• Moisture resistance

PSX is very hydrophobic which gives it real resistance to humidity. It thus prevents any moisture transfer between the inside and the outside.

• Packaging

Extruded polystyrene is found in fairly dense panels. The PSX plates are then placed directly on the surfaces to be insulated.

• Insulation of Buildings

Extruded polystyrene can be used for the insulation of new buildings but is not suitable for old buildings.

• Roof and attic insulation

It is very suitable for places where there is significant heat loss, which is why it is perfect for insulating roofs and attics. It thus prevents the entry of humidity and blocks heat loss.

• External wall insulation

Thanks to its hydrophobic characteristics, PSX is also a very good insulator for exterior walls.

• Floor insulation

The PSX is not afraid of compression, which is why it is perfectly suited to insulating floors.

• Insulation of HVAC systems (Heating, Ventilation and Air conditioning)
• Pipe and pipe insulation

Extruded polystyrene can be used to insulate pipes for refrigeration networks, chilled water pipes, negative fluids and frost protection.

It comes in the form of shells, staves, bottoms and shaped parts.

• Insulation for industry and process

PSX has high mechanical resistance, which is why it can be used as an insulator in industrial settings. It is resistant to temperatures ranging from -65 ° C to + 85 ° C.

SMI works in collaboration with the leaders in insulation based on extruded polystyrene, we are reseller of recognized brands such as Styrofoam. We thus offer a whole range of shells, staves and elbows in extruded polystyrene for the insulation of HVAC systems.
