Isolation phonique et thermique ITE et coquilles isolantes pour HVAC

Glass wool with a woolly consistency is obtained by melting from sand and recycled glass (cullet) (standard PR EN ISO 9229) 1. It was invented in 1938, by Russell Games Slayter of Owens-Corning2, since it has been used extensively for thermal insulation, sound insulation and fire protection of all types of buildings3.

Glass wool is produced from recycled sand and broken glass, it is one of the most widely used insulators in France.

Glass wool has several advantages:

• Thermal insulation

Glass wool has real thermal insulation properties. The air is trapped in its small cavities which allows it to have an insulating action and prevent heat loss.

Glass wool is one of the cheapest heat insulating materials on the market.

• Sound insulation

Glass wool has a porous and elastic structure which gives it real sound insulation power. Glass wool absorbs noise, shocks and vibrations and thus prevents the transmission of sound.

• Fire resistance

Glass wool is made up of elements which are incombustible in nature, which is why it participates in passive fire protection of buildings. It does not spread flames and does not conduct heat. Beyond its thermal and acoustic insulating capacities, it is also an ideal material for fire protection.

• Strength & durability

Glass wool does not warp over time, it retains its thickness and has a lifespan of about ten years.

• Moisture resistance

Glass wool is classified as non-hydrophilic, it does not absorb moisture from the air. When wet it should be allowed to dry so that it retains all of its insulating properties.

• Various packaging

Glass wool can be packaged in rolls, panels or flakes.

• Insulation of Buildings

Glass wool is one of the most common insulators in France in the building industry, it has a very low cost, which makes it possible to maintain good energy performance for a small budget.

• Roof insulation: attic

Glass wool can be used for the insulation of lost and convertible attics. This material helps to reduce heat loss and helps save energy in structures.

Several types of packaging are possible: flexible rolls, semi-rigid rolls or wool flakes.

• Exterior and interior insulation of walls

As part of thermal and acoustic insulation from the inside, the glass wool used comes in two forms: semi-rigid rolls (high mechanical resistance) or rigid panels. It is placed on the interior wall of the walls and thus prevents thermal bridges and heat loss.

For thermal insulation on the outside, glass wool is this time in the form of semi-rigid panels placed on the exterior facade of the building.

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

Glass wool can also be used as an insulation for ventilation, air conditioning and heating systems.

• Insulation of ventilation ducts and ducts

Glass wool is used as an insulation for ventilation and air conditioning ducts. It acts as thermal and acoustic insulator through the interior or exterior of aeraulic networks conveying air.

Insulating the ventilation ducts helps maintain the temperature of the air flow inside the duct.

• Pipe and pipe insulation

Glass wool can also be used for the insulation of heating pipes and domestic hot water.

It then comes in the form of cylindrical shells that surround the outside of the pipes.

• Insulation for industry and process

Glass wool is an insulating material for industry and is used for thermal insulation, industry vapor insulation, heating pipes, domestic hot water and hot applications.

SMI offers a whole range of glass wool-based insulation for use in building insulation, heating, ventilation and heating systems as well as for industry and its processes.

We work with ISOVER, a leading company in glass wool insulation. We offer several products in their range: interior and exterior sheath felts, interior sheath panels for the insulation of your ventilation ducts. Protective shells for heating and domestic hot water pipes…
