Isolant thermique et phonique adapté à la protection incendie

Phenolic (or resolic) foam is a very rigid, closed-pore foam made from an emulsion of a phenoplast (a phenol-formaldehyde resin that was once used to produce bakelite). It is used for its thermal insulation properties, its resistance to crushing and its heat resistance1. It is one of the best insulation on the market: more efficient than polystyrene, and can replace polyurethane foam.

Phenolic foam is a synthetic insulating material produced from petroleum derivatives, it is also known as “resolic foam”. This foam has many insulating properties:

• Thermal insulation

Phenolic foam has been specially developed as an insulator, which is why it has very effective thermal insulation properties. It is the most efficient thermal insulation on the market. Thanks to a high insulation value (0.020W / mK), it has an excellent thickness / performance ratio.

• Sound insulation

The honeycomb structure of phenolic foam makes it a very good sound insulator. It thus absorbs sounds, noises and vibrations within its cells and does not propagate parasitic noise. An ideal material for insulating walls and partitions.

• Fire resistance

Resole foam has very good fire resistance, it is even used in the manufacture of fire doors. In the event of fire, the foam resists combustion and emits little toxic smoke.

• Strength & durability

Phenolic foam has a fairly long lifespan, so it provides long-lasting thermal and sound insulation.

• Moisture resistance

Phenolic foam is not waterproof, which is why it is not as is, not moisture resistant. It therefore needs to be coupled with a vapor barrier or waterproof coating in order to provide optimal insulation performance and not suffer damage from humidity.

• Packaging

The phenolic foam is packaged in the form of rigid panels.

• Insulation of Buildings
• Roof insulation

This insulation can be used for roof and attic insulation, it can be used outside or inside the roof. The installation of phenolic foam panels must in all cases be accompanied by a vapor barrier.

• Exterior and interior insulation of walls

Phenolic foam can also be used for wall insulation, given its low thickness it can be used to insulate walls from the inside with the addition of a vapor barrier or waterproof coating.

• Floor insulation

Its sturdiness allows it to withstand a significant amount of weight, which is why it is also used as insulation for floors.

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

Phenolic foam is also used as cold and hot pipe insulation. It is used as a shell coupled with a vapor barrier on chilled water, cold water and hot water pipes.

It is resistant to temperatures between -50 ° C and + 110 ° C

• Insulation for industry and process

The characteristics of phenolic foam make it an effective insulator in the industrial sector. It comes in the form of shells and elbows to fit mild steel, stainless steel, carbon, copper and plastic pipes.

SMI offers Kingspan brand shells and elbows, the market leader in phenolic foam insulation. The products are perfectly suited to industrial and construction uses.
